title="原因"></a>原因</h3><p>在tomcat官方wiki文档的<em><a href="https://wiki.apache.org/tomcat/HowTo/FasterStartUp" target="_blank" rel="noopener">HowToFasterStartUp</a></em>章节中，Entropy Source部分有一段这样的说明：</p><blockquote><p>Tomcat 7+严重依赖SecureRandom类为其sessionID和其他地方提供随机值。如果用于初始化SecureRandom的熵源缺少熵，则可能会在启动期间导致延迟，具体取决于您的JRE。发生这种情况时，您会在日志中看到警告，例如：<br><strong><date> org.apache.catalina.util.SessionIdGenerator createSecureRandom<br>INFO: Creation of SecureRandom instance for session ID generation using [SHA1PRNG] took [5172] milliseconds.</date></strong><br>有一种方法可以通过设置以下系统属性来配置JRE以使用非阻塞熵源：<br><strong>-Djava.security.egd = file:/dev/./urandom</strong><br>另请注意，使用非阻塞源替换阻塞熵源实际上会降低安全性，因为您获得的随机数据较少。</p></blockquote><p>从这里我们得知Tocmat的Session ID是通过SHA1PRNG算法计算得到的，计算Session ID的时候必须有一个密钥，为了提高安全性Tomcat在启动的时候会通过随机生成一个密钥，它强依赖于获取熵池中的随机数来进行创建。<br>那么什么是<strong>/dev/random</strong>？什么是<strong>熵池</strong>？</p><p><strong>/dev/random</strong><br>从维基百科得知，在UNIX操作系统（包括类UNIX系统）中，<code>/dev/random</code>是一个特殊的设备文件，可以用作随机数生成器或伪随机数生成器。<br>Linux内核中的是第一个以<code>背景噪声</code>产生真正的随机数产生的实现，它允许程序访问来自设备驱动程序或其它来源的背景噪声。<br>Linux上有两个通用的随机设备：<code>/dev/random</code>和<code>/dev/urandom</code>。其中<code>/dev/random</code>的随机性最好，因为它是一个阻塞的设备。而<code>/dev/random</code>的一个副本是<code>/dev/urandom</code>（“unblocked”，非阻塞的随机数生成器），它会重复使用熵池中的数据以产生伪随机数据。这表示对<code>/dev/urandom</code>的读取操作不会产生阻塞，但其输出的熵可能小于<code>/dev/random</code>的。所以它可以作为生成较低强度密码的伪随机数生成器，不建议用于生成高强度长期密码。</p><p><strong>熵池</strong><br>熵池本质上是若干字节，<code>/proc/sys/kernel/random/entropy_avail</code>中存储了熵池现在的大小，<code>/proc/sys/kernel/random/poolsize</code>是熵池的最大容量，单位都是bit。如果<code>entropy_avail</code>的值小于要产生的随机数bit数，那么<code>/dev/random</code>就会堵塞。</p><p><strong>为什么熵池不够用？</strong></p><p>熵池实际上是从各种noice source中获取数据，noice source可能是键盘事件、鼠标事件、设备时钟中等。linux内核从2.4升级到2.6时，处于安全性的考虑，废弃了一些source。source减少了，熵池补给的速度当然也变慢，进而不够用。<br>其实，通过消耗熵池，可以构造DDOS攻击。原理很简单，熵池空了，依赖随机数的业务（SSL，加密等）就不能正常进行。</p><p>通过以上信息，笔者得知该问题是由于熵池不足导致的。<strong>怎么解决？</strong></p><h3

上一篇我们讲到分析有道翻译接口请求，并利用python3构造参数爬取接口。在本篇中，我将会针对有道翻译接口进行图形化界面的设计。</p><h4 id="一、器欲尽其能，必先得其法。"><a href="#一、器欲尽其能，必先得其法。" class="headerlink" title="一、器欲尽其能，必先得其法。"></a>一、器欲尽其能，必先得其法。</h4><p> 像java中的<code>AWT</code>和<code>Swing</code>一样，在python3中也自带了GUI工具包，利用其中的<code>Tkinter</code>组件，我们可以方便快捷的设计我们的图形界面。</p><p>PS：需要注意的是，在python2和python3中其导入方式存在差异。<br><figure class="highlight

title="三、只要功夫深，铁杵磨成针"></a>三、只要功夫深，铁杵磨成针</h4><p>对<code>tkinter</code>有了简单的了解后，首先我们在面板上添加文本区组件和按钮组件，将主要功能展示出来<br><img src="/assets/blogImg/youdao-spider-bottom/youdao-spider-bottom-1.png" class="img-center-normal"></p><p>其次，我们针对不同的语言增加翻译选项<br><img src="/assets/blogImg/youdao-spider-bottom/youdao-spider-bottom-2.png" class="img-center-normal"></p><p>重新调整组件和布局<br><img src="/assets/blogImg/youdao-spider-bottom/youdao-spider-bottom-3.png" class="img-center-normal"></p><p>这样，一个简单的GUI界面就实现了，好像有点丑，一股浓浓的windows经典风格。。。</p><h4 id="四、不畏浮云遮望眼，只缘身在最高层。"><a href="#四、不畏浮云遮望眼，只缘身在最高层。" class="headerlink" title="四、不畏浮云遮望眼，只缘身在最高层。"></a>四、不畏浮云遮望眼，只缘身在最高层。</h4><p> 我们前面都是直接使用<code>tkinter</code>模块下的 GUI 组件，这些组件看上去特别复(chou)古(lou)，仿佛将我门带回了20年前。为了更好的视觉效果，<code>Tkinter</code>后来引入了一个<code>ttk</code>组件作为补充（主要就是简单包装、美化一下），并使用功能更强大的Combobox取代了原来的Listbox，且新增了 LabeledScale（带标签的 Scale）、Notebook（多文档窗口）、Progressbar（进度条）、Treeview（树）等组件。ttk作为一个模块被放在tkinter包下，使用ttk组件与使用普通的Tkinter组件并没有多大的区别，只要导入ttk模块即可。<br> 其实，tkinter中还存在一个进阶组件ttk，tk带有17个小部件，其中11个已经存在于tkinter中：Button，Checkbutton，Entry，Frame，Label，LabelFrame，Menubutton，PanedWindow，Radiobutton，Scale和Scrollbar。 6个新的窗口小部件类是：Combobox，Notebook，Progressbar，Separator，Sizegrip和Treeview。所有这些类都是Widget的子类。<br>导入方式如下：<br><figure class="highlight capnproto"><table><tr><td class="gutter"><pre><span

src="/assets/blogImg/youdao-spider-bottom/youdao-spider-bottom-4.png" class="img-center-normal"></p><p>还可利用<code>Progressbar</code>进度条组件，增加进度条显示<br><img src="/assets/blogImg/youdao-spider-bottom/youdao-spider-bottom-5.png" class="img-center-normal"></p><p>以及菜单、多标签和弹出窗体的实现</p><p><img src="/assets/blogImg/youdao-spider-bottom/youdao-spider-bottom-6.png"

class="img-center-normal"></p><p>我们还可利用<code>pyinstaller</code>将程序打包成exe在windows平台上进行方便的使用，这样我们利用python的GUI就完成了有道词典的图形界面制作。</p><p>最后，附上完整代码：<br><figure class="highlight routeros"><table><tr><td

<content type="html"><![CDATA[<p><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-0.jpg" class="img-center-slider"><br> 平时偶尔会用到翻译工具，其中最常用的就是有道翻译了，web端的有道翻译，在早期是直接可以爬到接口来使用的，但自从有道翻译推出他的API服务的时候，就对这个接口做了反爬虫的机制，从而来推广他的付费接口服务。这个反爬虫机制在爬虫领域算是一个非常经典的技术手段，今天我们就来对它一探究竟吧。</p><a id="more"></a><h4 id="一、莫听穿林打叶声，何妨吟啸且徐行。"><a href="#一、莫听穿林打叶声，何妨吟啸且徐行。" class="headerlink" title="一、莫听穿林打叶声，何妨吟啸且徐行。"></a>一、莫听穿林打叶声，何妨吟啸且徐行。</h4><p>首先我们使用chrome浏览器打开有道翻译的链接：<a href="http://fanyi.youdao.com" target="_blank" rel="noopener">http://fanyi.youdao.com</a><br>然后使用<code>F12</code>或<code>ctrl+shift+i</code>唤起“开发者工具”，鼠标右键点击<code>检查</code>一样，也就是审查元素，选择<code>Network</code>网络监听窗口，如下图所示，之后页面中所有的请求都会在这里显示出来：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-1.png" class="img-center-normal"></p><p>接着我们在左侧翻译的窗口输入我们需要翻译的文字，比如输入“你好”，然后浏览器就会向有道发起异步ajax请求，在下面就可以看到所有的请求：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-2.png" class="img-center-normal"></p><p>我们点开第一条请求，在<code>Headers</code>可以看到，在进行翻译的时候，发送的请求就是图中<code>Request URL</code>后的URL：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-3.png" class="img-center-normal"></p><p>接着我们滚动到最下面，可以看到有一个<code>Form Data</code>的地方，这是请求时所携带的参数，这些数据就是在翻译的时候浏览器给服务器发送的数据：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-4.png" class="img-center-normal"><br><em>Tip：在我们请求多次后，发现每次翻译时有些参数固定不变，而有些参数会动态变化，这就是我们破解有道反爬虫机制的关键点，后面会讲到。</em></p><p>然后再点击<code>Response</code>，这里就是接口返回的结果：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-5.png" class="img-center-normal"></p><p>最后我们选择<code>Application</code>应用窗口，点击左侧<code>Storage</code>-<code>Cookies</code>,选择有道翻译的域名，这里存储的是cookie信息，cookie校验也是反爬虫的常见手段，这也是我们后面需要注意的：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-6.png" class="img-center-normal"></p><h4 id="二、工欲善其事，必先利其器。"><a href="#二、工欲善其事，必先利其器。" class="headerlink" title="二、工欲善其事，必先利其器。"></a>二、工欲善其事，必先利其器。</h4><blockquote><p>运行平台：Windows<br>Python版本：Python3.x<br>IDE：Eclipse + PyDev插件</p></blockquote><p>到现在为止，我们得到了url和入参，我们就可以简单写一个爬虫，去调用有道翻译的接口了，我们选用python3来进行爬虫编写。<br>这里使用的是Python3自带的网络请求库urllib，也伪造一下包括cookie在内的请求头，相关代码如下：<br><figure class="highlight

50}</code>，这就是有道词典的反爬虫机制，接下来我们就来一步一步破解它。</p><h4 id="三、横看成岭侧成峰，远近高低各不同。"><a href="#三、横看成岭侧成峰，远近高低各不同。" class="headerlink" title="三、横看成岭侧成峰，远近高低各不同。"></a>三、横看成岭侧成峰，远近高低各不同。</h4><p>我们刚才有讲到，在有道翻译web页面尝试进行了多次翻译，并且每次翻译后都去查看相应的网络请求入参，比较每次请求的<code>Form Data</code>的值，我们注意到，除<code>i</code>代表翻译的源字符串以外，<code>salt</code>和<code>sign</code>以及<code>ts</code>这三个参数是动态变化的，其他的参数都是固定值。<br>这里我分别用“great”和“date”两个单词翻译时候<code>Form Data</code>的数据进行比较：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-7.png" class="img-center-normal"></p><p>经过多次变换语种等尝试，观察键值的变化，我们可以对请求携带的参数有如下猜测：</p><ul><li>i：需要进行翻译的字符串</li><li>from：源语言的语种</li><li>to：翻译后的语种</li><li>smartresult：智能结果，固定值</li><li>client：客户端，固定值</li><li>salt：加密用到的盐，待定</li><li>sign：签名字符串，待定</li><li>ts：毫秒时间戳</li><li>bv：未知的md5值，固定值</li><li>doctype：文档类型，固定值</li><li>version：版本，固定值</li><li>keyfrom：键来源，固定值</li><li>action：操作动作，固定值</li><li>typoResult：是否打印错误，固定值</li></ul><p>那么这三个动态参数的值是怎么产生的呢？这里我们可以分析一下，这三个值在每次请求的时候都不一样，只有两种情况：<br>第一是每次翻译的时候，浏览器会从有道服务器获取这三个值。这样可以达到每次翻译的时候值不同的需求。<br>第二是在本地，用js代码按照一定的规则生成的。<br>那么我们首先来看第一个情况，我们可以看到在每次发送翻译请求的时候，并没有一个请求是专门用来获取这几个值的：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-8.png" class="img-center-normal"></p><p>所以就可以排除了第一种情况。就只剩下一种可能，那就是在本地自己生成的，如果是在本地自己生成的，那么规则是什么呢？</p><h4 id="四、欲穷千里目，更上一层楼。"><a href="#四、欲穷千里目，更上一层楼。" class="headerlink" title="四、欲穷千里目，更上一层楼。"></a>四、欲穷千里目，更上一层楼。</h4><p>这里我们点击<code>Elements</code>审查元素，查看网页源代码，查找所有的js文件，找到一个<code>fanyi.min.js</code>：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-9.png" class="img-center-normal"></p><p>同样，我们在<code>Sources</code>-<code>Page</code>中也可以看到该js文件：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-10.png" class="img-center-normal"></p><p>打开该js文件，可以看到该js是被压缩过的，我们复制出来使用在线格式化工具对齐进行格式化，然后把格式化后的代码，复制下来，用编辑器打开，然后搜索<code>salt</code>，可以找到相关的代码片段：<br><img src="/assets/blogImg/youdao-spider-top/youdao-spider-top-11.jpg" class="img-center-normal"></p><p>这里我们就可以发现动态值的生成原理了：</p><ul><li>i：需要进行翻译的字符串的前5000字</li><li>salt：当前毫秒时间戳与10以内随机数字字符串的拼接</li><li>sign：”fanyideskweb”+i+salt+”p09@Bn{h02_BIEe]$P^nG”的md5值</li><li>ts：当前毫秒时间戳</li></ul><p>在得到<code>salt</code>和<code>sign</code>以及<code>ts</code>的生成原理后，我们就可以开始进一步改写Python代码，来对接有道的接口了：<br><figure

title="一、NoSQL简介"></a>一、NoSQL简介</h3><p> NoSQL(NoSQL = Not Only SQL )，意即“不仅仅是SQL”，泛指非关系型的数据库。<br> NoSQL 是一项全新的数据库革命性运动，早期就有人提出，发展至2009年趋势越发高涨。NoSQL的拥护者们提倡运用非关系型的数据存储，相对于铺天盖地的关系型数据库运用，这一概念无疑是一种全新的思维的注入，NoSQL的非关系特性助力大型Web2.0网站的再次起飞，使其成为了后Web2.0时代的宠儿。<br><a id="more"></a></p><h4 id="单机时代模型"><a href="#单机时代模型" class="headerlink" title="单机时代模型"></a>单机时代模型</h4><p><img src="/assets/blogImg/nosql-redis/nosql-redis-1.png" class="img-center-normal"><br> 如果每次存储成千上万条数据，这样很会导致mysql的性能很差，存储以及读取速度很慢，然后就演变成缓存+mysql+垂直拆分的方式。</p><h4 id="Cache作为中间缓存"><a href="#Cache作为中间缓存" class="headerlink" title="Cache作为中间缓存"></a>Cache作为中间缓存</h4><p><img src="/assets/blogImg/nosql-redis/nosql-redis-2.png" class="img-center-normal"><br> 将所有的数据先保存到缓存中，然后再存入mysql中，减小数据库压力，提高效率。<br> 但是当数据再次增加到又一个量级，上面的方式也不能满足需求，由于数据库的写入压力增加，Memcached只能缓解数据库的读取压力。读写集中在一个数据库上让数据库不堪重负，大部分网站开始使用主从复制技术来达到读写分离，以提高读写性能和读库的可扩展性。Mysql的master-slave模式成为这个时候的网站标配了。 </p><h4 id="主从分离模式"><a href="#主从分离模式" class="headerlink" title="主从分离模式"></a>主从分离模式</h4><p><img src="/assets/blogImg/nosql-redis/nosql-redis-3.png" class="img-center-normal"><br> 在redis的高速缓存，MySQL的主从复制，读写分离的基础之上，这时MySQL主库的写压力开始出现瓶颈，而数据量的持续猛增，由于MyISAM使用表锁，在高并发下会出现严重的锁问题，大量的高并发MySQL应用开始使用InnoDB引擎代替MyISAM。 </p><h4 id="分表分库模式"><a href="#分表分库模式" class="headerlink" title="分表分库模式"></a>分表分库模式</h4><p><img src="/assets/blogImg/nosql-redis/nosql-redis-4.png" class="img-center-normal"><br> 将变化小的、业务相关的放在一个数据库，变化多的，不相关的数据放在一个数据库。</p><h3 id="二、NoSQL的风声水起"><a href="#二、NoSQL的风声水起" class="headerlink" title="二、NoSQL的风声水起"></a>二、NoSQL的风声水起</h3><p><img src="/assets/blogImg/nosql-redis/nosql-redis-5.png" class="img-center-normal"><br> 随着互联网web2.0网站的兴起，传统的关系数据库在应付web2.0网站，特别是超大规模和高并发的SNS类型的web2.0纯动态网站已经显得力不从心，暴露了很多难以克服的问题：</p><h5 id="1-对数据库高并发读写的需求"><a href="#1-对数据库高并发读写的需求" class="headerlink" title="1. 对数据库高并发读写的需求"></a>1. 对数据库高并发读写的需求</h5><p> 网站要根据用户个性化信息来实时生成动态页面和提供动态信息，所以基本上无法使用动态页面静态化技术，因此数据库并发负载非常高，往往要达到每秒上万次读写请求。关系数据库应付上万次SQL查询还勉强顶得住，但是应付上万次SQL写数据请求，硬盘IO就已经无法承受了。</p><h5 id="2-对海量数据的高效率存储和访问的需求"><a href="#2-对海量数据的高效率存储和访问的需求" class="headerlink" title="2. 对海量数据的高效率存储和访问的需求"></a>2. 对海量数据的高效率存储和访问的需求</h5><p> 对于大型的SNS网站，每天用户产生海量的用户动态，以国外的Friendfeed为例，一个月就达到了2.5亿条用户动态，对于关系数据库来说，在一张2.5亿条记录的表里面进行SQL查询，效率是极其低下乃至不可忍受的。</p><h5 id="3-对数据库的高可扩展性和高可用性的需求"><a href="#3-对数据库的高可扩展性和高可用性的需求" class="headerlink" title="3. 对数据库的高可扩展性和高可用性的需求"></a>3. 对数据库的高可扩展性和高可用性的需求</h5><p> 在基于Web的架构当中，数据库是最难进行横向扩展的，当一个应用系统的用户量和访问量与日俱增的时候，你的数据库却没有办法像Web服务器和应用服务器那样简单的通过添加更多的硬件和服务节点来扩展性能和负载能力。对于很多需要提供7*24小时不间断服务的网站来说，对数据库系统进行升级和扩展是非常痛苦的事情，往往需要停机维护和数据迁移，为什么数据库不能通过不断的添加服务器节点来实现扩展呢？</p><p> 在上面提到的“三高”的需求面前，关系数据库遇到了难以克服的障碍，而对于Web2.0网站来说，关系数据库的很多主要特性却往往无用武之地，例如：</p><h5 id="1-数据库事务一致性需求"><a href="#1-数据库事务一致性需求" class="headerlink" title="1. 数据库事务一致性需求"></a>1. 数据库事务一致性需求</h5><p> 很多Web实时系统并不要求严格的数据库事务，对读一致性的要求很低，有些场合对写一致性要求也不高。因此数据库事务管理成了数据库高负载下一个沉重的负担。</p><h5 id="2-数据库的写实时性和读实时性需求"><a href="#2-数据库的写实时性和读实时性需求" class="headerlink" title="2. 数据库的写实时性和读实时性需求"></a>2. 数据库的写实时性和读实时性需求</h5><p> 对关系数据库来说，插入一条数据之后立刻查询，是肯定可以读出来这条数据的。并不要求这么高的实时性。</p><h5 id="3-对复杂的SQL查询，特别是多表关联查询的需求"><a href="#3-对复杂的SQL查询，特别是多表关联查询的需求" class="headerlink" title="3. 对复杂的SQL查询，特别是多表关联查询的需求"></a>3. 对复杂的SQL查询，特别是多表关联查询的需求</h5><p> 任何大数据量的Web系统，都非常忌讳多个大表的关联查询，以及复杂的数据分析类型的复杂SQL报表查询，特别是SNS类型的网站，从需求以及产品设计角度，就避免了这种情况的产生。往往更多的只是单表的主键查询，以及单表的简单条件分页查询，SQL的功能被极大的弱化了。</p><blockquote><p>而非关系型的数据库则由于其本身的特点得到了非常迅速的发展。NoSQL数据库的产生就是为了解决大规模数据集合多重数据种类带来的挑战，尤其是大数据应用难题。<br><img src="/assets/blogImg/nosql-redis/nosql-redis-6.png" class="img-center-normal"></p></blockquote><h3 id="三、NoSQL无与伦比的特点"><a href="#三、NoSQL无与伦比的特点" class="headerlink" title="三、NoSQL无与伦比的特点"></a>三、NoSQL无与伦比的特点</h3><p>在大数据存取上具备关系型数据库无法比拟的性能优势，例如：</p><h5 id="1-易扩展"><a href="#1-易扩展" class="headerlink" title="1. 易扩展"></a>1. 易扩展</h5><p> NoSQL数据库种类繁多，但是一个共同的特点都是去掉关系数据库的关系型特性。数据之间无关系，这样就非常容易扩展。也无形之间，在架构的层面上带来了可扩展的能力。</p><h5 id="2-大数据量，高性能"><a href="#2-大数据量，高性能" class="headerlink" title="2. 大数据量，高性能"></a>2. 大数据量，高性能</h5><p> NoSQL数据库都具有非常高的读写性能，尤其在大数据量下，同样表现优秀。这得益于它的无关系性，数据库的结构简单。</p><h5 id="3-多样灵活的数据模型"><a href="#3-多样灵活的数据模型" class="headerlink" title="3. 多样灵活的数据模型"></a>3. 多样灵活的数据模型</h5><p> 在NoSQL中不仅可以存储String，hash，set、Zset等数据类型，还可以保存javaBean以及多种复杂的数据类型。NoSQL无需事先为要存储的数据建立字段，随时可以存储自定义的数据格式。而在关系数据库里，增删字段是一件非常麻烦的事情。如果是非常大数据量的表，增加字段简直就是一个噩梦。这点在大数据量的Web2.0时代尤其明显。</p><h5 id="4-高可用"><a href="#4-高可用" class="headerlink" title="4. 高可用"></a>4. 高可用</h5><p> NoSQL在不太影响性能的情况，就可以方便的实现高可用的架构。比如Cassandra，HBase模型，通过复制模型也能实现高可用。</p><h3 id="四、Redis的脱颖而出"><a href="#四、Redis的脱颖而出" class="headerlink" title="四、Redis的脱颖而出"></a>四、Redis的脱颖而出</h3><p><img src="/assets/blogImg/nosql-redis/nosql-redis-7.png" class="img-center-logo"></p><h4 id="1、redis简介"><a href="#1、redis简介" class="headerlink" title="1、redis简介"></a>1、redis简介</h4><p> redis是NoSQL数据库中使用较为广泛的非关系型内存数据库，redis内部是一个key-value存储系统。它支持存储的value类型相对更多，包括string(字符串)、list(链表)、set(集合)、zset(sorted set –有序集合)和hash（哈希类型，类似于Java中的map）。Redis基于内存运行并支持持久化的NoSQL数据库，是当前最热门的NoSql数据库之一，也被人们称为数据结构服务器。</p><h4 id="2、redis特点"><a href="#2、redis特点" class="headerlink" title="2、redis特点"></a>2、redis特点</h4><ol><li>速度快<br>Redis是用C语言实现的；<br>Redis的所有数据存储在内存中。 </li><li>持久化<br>Redis的所有数据存储在内存中，对数据的更新将异步地保存到磁盘上。 </li><li>支持多种数据结构<br>Redis支持五种数据结构：String、List、Set、Hash、Zset </li><li>支持多种编程语言<br>Java、php、Python、Ruby、Lua、Node.js </li><li>功能丰富<br>除了支持五种数据结构之外，还支持事务、流水线、发布/订阅、消息队列等功能。 </li><li>源码简单<br>约23000行C语言源代码。 </li><li>主从复制<br>主服务器（master）执行添加、修改、删除，从服务器执行查询。 </li><li>高可用及分布式<br>Redis-Sentinel（v2.8）支持高可用<br>Redis-Cluster（v3.0）支持分布式</li></ol><p> 和Memcached类似，Redis支持存储的value类型相对更多，包括string(字符串)、list(链表)、set(集合)、zset(sorted set –有序集合)和hash（哈希类型）。这些数据类型都支持push/pop、add/remove及取交集并集和差集及更丰富的操作，而且这些操作都是原子性的。在此基础上，Redis支持各种不同方式的排序。与Memcached一样，为了保证效率，数据都是缓存在内存中。区别的是Redis会周期性的把更新的数据写入磁盘或者把修改操作写入追加的记录文件，并且在此基础上实现了master-slave(主从)同步（数据可以从主服务器向任意数量的从服务器上同步，从服务器可以是关联其他从服务器的主服务器。）。<br> 因此，Redis的出现，很大程度补偿了Memcached这类key/value存储的不足，在部分场合可以对关系数据库起到很好的补充作用。</p><h4 id="3、如何使用redis"><a href="#3、如何使用redis" class="headerlink" title="3、如何使用redis?"></a>3、如何使用redis?</h4><p> 你一定要知道的是：redis的key名要区分大小写，在redis中除了 和空格外，其他的字符都可以做为key名，且长度不做限制，不过为了性能考虑，一般key名不要设置的太长。redis功能强大，支持数据类型丰富，以下是redis操作命令大全，基本上涵盖了redis所有的命令！</p><h5 id="1、redis命令基本篇"><a href="#1、redis命令基本篇"

<title>JVM的内存区域划分</title>

<content type="html"><![CDATA[<p><img src="/assets/blogImg/jvm-memory-division/jvm-memory-division-0.png" class="img-center-logo"><br> 学过C语言的朋友都知道C编译器在划分内存区域的时候经常将管理的区域划分为数据段和代码段，数据段包括堆、栈以及静态数据区。那么在Java语言当中，内存又是如何划分的呢？<br> 由于Java程序是交由JVM执行的，所以我们在谈Java内存区域划分的时候事实上是指JVM内存区域划分。</p><a id="more"></a><p> 在讨论JVM内存区域划分之前，先来看一下Java程序具体执行的过程：<br><img src="/assets/blogImg/jvm-memory-division/jvm-memory-division-1.jpg" class="img-center-normal"><br> 如上图所示，首先Java源代码文件(.java后缀)会被Java编译器编译为字节码文件(.class后缀)，然后由JVM中的类加载器加载各个类的字节码文件，加载完毕之后，交由JVM执行引擎执行。在整个程序执行过程中，JVM会用一段空间来存储程序执行期间需要用到的数据和相关信息，这段空间一般被称作为Runtime Data Area（运行时数据区），也就是我们常说的JVM内存。因此，在Java中我们常常说到的内存管理就是针对这段空间进行管理（如何分配和回收内存空间）。<br> 在知道了JVM内存是什么东西之后，下面我们就来讨论一下这段空间具体是如何划分区域的，是不是也像C语言中一样也存在栈和堆呢？</p><h3 id="一、运行时数据区包括哪几部分？"><a href="#一、运行时数据区包括哪几部分？" class="headerlink" title="一、运行时数据区包括哪几部分？"></a>一、运行时数据区包括哪几部分？</h3><p> 根据《Java虚拟机规范》的规定，运行时数据区通常包括这几个部分：程序计数器(Program Counter Register)、Java栈(VM Stack)、本地方法栈(Native Method Stack)、方法区(Method Area)、堆(Heap)。<br><img src="/assets/blogImg/jvm-memory-division/jvm-memory-division-2.jpg" class="img-center-normal"><br> 如上图所示，JVM中的运行时数据区应该包括这些部分。在JVM规范中虽然规定了程序在执行期间运行时数据区应该包括这几部分，但是至于具体如何实现并没有做出规定，不同的虚拟机厂商可以有不同的实现方式。</p><h3 id="二、运行时数据区的每部分到底存储了哪些数据？"><a href="#二、运行时数据区的每部分到底存储了哪些数据？" class="headerlink" title="二、运行时数据区的每部分到底存储了哪些数据？"></a>二、运行时数据区的每部分到底存储了哪些数据？</h3><p> 下面我们来了解一下运行时数据区的每部分具体用来存储程序执行过程中的哪些数据。</p><h4 id="1、程序计数器"><a href="#1、程序计数器" class="headerlink" title="1、程序计数器"></a>1、程序计数器</h4><p> 程序计数器（Program Counter Register），也有称作为PC寄存器。想必学过汇编语言的朋友对程序计数器这个概念并不陌生，在汇编语言中，程序计数器是指CPU中的寄存器，它保存的是程序当前执行的指令的地址（也可以说保存下一条指令的所在存储单元的地址），当CPU需要执行指令时，需要从程序计数器中得到当前需要执行的指令所在存储单元的地址，然后根据得到的地址获取到指令，在得到指令之后，程序计数器便自动加1或者根据转移指针得到下一条指令的地址，如此循环，直至执行完所有的指令。<br> 虽然JVM中的程序计数器并不像汇编语言中的程序计数器一样是物理概念上的CPU寄存器，但是JVM中的程序计数器的功能跟汇编语言中的程序计数器的功能在逻辑上是等同的，也就是说是用来指示 执行哪条指令的。<br> 由于在JVM中，多线程是通过线程轮流切换来获得CPU执行时间的，因此，在任一具体时刻，一个CPU的内核只会执行一条线程中的指令，因此，为了能够使得每个线程都在线程切换后能够恢复在切换之前的程序执行位置，每个线程都需要有自己独立的程序计数器，并且不能互相被干扰，否则就会影响到程序的正常执行次序。因此，可以这么说，程序计数器是每个线程所私有的。<br> 在JVM规范中规定，如果线程执行的是非native方法，则程序计数器中保存的是当前需要执行的指令的地址；如果线程执行的是native方法，则程序计数器中的值是undefined。<br> 由于程序计数器中存储的数据所占空间的大小不会随程序的执行而发生改变，因此，对于程序计数器是不会发生内存溢出现象(OutOfMemory)的。</p><h4 id="2、Java栈"><a href="#2、Java栈" class="headerlink" title="2、Java栈"></a>2、Java栈</h4><p> Java栈也称作虚拟机栈（Java Vitual Machine Stack），也就是我们常常所说的栈，跟C语言的数据段中的栈类似。事实上，Java栈是Java方法执行的内存模型。为什么这么说呢？下面就来解释一下其中的原因。<br> Java栈中存放的是一个个的栈帧，每个栈帧对应一个被调用的方法，在栈帧中包括局部变量表(Local Variables)、操作数栈(Operand Stack)、指向当前方法所属的类的运行时常量池（运行时常量池的概念在方法区部分会谈到）的引用(Reference to runtime constant pool)、方法返回地址(Return Address)和一些额外的附加信息。当线程执行一个方法时，就会随之创建一个对应的栈帧，并将建立的栈帧压栈。当方法执行完毕之后，便会将栈帧出栈。因此可知，线程当前执行的方法所对应的栈帧必定位于Java栈的顶部。讲到这里，大家就应该会明白为什么 在 使用 递归方法的时候容易导致栈内存溢出的现象了以及为什么栈区的空间不用程序员去管理了（当然在Java中，程序员基本不用关系到内存分配和释放的事情，因为Java有自己的垃圾回收机制），这部分空间的分配和释放都是由系统自动实施的。对于所有的程序设计语言来说，栈这部分空间对程序员来说是不透明的。下图表示了一个Java栈的模型：<br><img src="/assets/blogImg/jvm-memory-division/jvm-memory-division-3.jpg" class="img-center-normal"><br> 局部变量表，顾名思义，想必不用解释大家应该明白它的作用了吧。就是用来存储方法中的局部变量（包括在方法中声明的非静态变量以及函数形参）。对于基本数据类型的变量，则直接存储它的值，对于引用类型的变量，则存的是指向对象的引用。局部变量表的大小在编译器就可以确定其大小了，因此在程序执行期间局部变量表的大小是不会改变的。<br> 操作数栈，想必学过数据结构中的栈的朋友想必对表达式求值问题不会陌生，栈最典型的一个应用就是用来对表达式求值。想想一个线程执行方法的过程中，实际上就是不断执行语句的过程，而归根到底就是进行计算的过程。因此可以这么说，程序中的所有计算过程都是在借助于操作数栈来完成的。<br> 指向运行时常量池的引用，因为在方法执行的过程中有可能需要用到类中的常量，所以必须要有一个引用指向运行时常量。<br> 方法返回地址，当一个方法执行完毕之后，要返回之前调用它的地方，因此在栈帧中必须保存一个方法返回地址。<br> 由于每个线程正在执行的方法可能不同，因此每个线程都会有一个自己的Java栈，互不干扰。</p><h4 id="3、本地方法栈"><a href="#3、本地方法栈" class="headerlink" title="3、本地方法栈"></a>3、本地方法栈</h4><p> 本地方法栈与Java栈的作用和原理非常相似。区别只不过是Java栈是为执行Java方法服务的，而本地方法栈则是为执行本地方法（Native Method）服务的。在JVM规范中，并没有对本地方发展的具体实现方法以及数据结构作强制规定，虚拟机可以自由实现它。在HotSopt虚拟机中直接就把本地方法栈和Java栈合二为一。</p><h4 id="4、堆"><a href="#4、堆" class="headerlink" title="4、堆"></a>4、堆</h4><p> 在C语言中，堆这部分空间是唯一一个程序员可以管理的内存区域。程序员可以通过malloc函数和free函数在堆上申请和释放空间。那么在Java中是怎么样的呢？<br> Java中的堆是用来存储对象本身的以及数组（当然，数组引用是存放在Java栈中的）。只不过和C语言中的不同，在Java中，程序员基本不用去关心空间释放的问题，Java的垃圾回收机制会自动进行处理。因此这部分空间也是Java垃圾收集器管理的主要区域。另外，堆是被所有线程共享的，在JVM中只有一个堆。</p><h4 id="5、方法区"><a href="#5、方法区" class="headerlink" title="5、方法区"></a>5、方法区</h4><p> 方法区在JVM中也是一个非常重要的区域，它与堆一样，是被线程共享的区域。在方法区中，存储了每个类的信息（包括类的名称、方法信息、字段信息）、静态变量、常量以及编译器编译后的代码等。<br> 在Class文件中除了类的字段、方法、接口等描述信息外，还有一项信息是常量池，用来存储编译期间生成的字面量和符号引用。<br> 在方法区中有一个非常重要的部分就是运行时常量池，它是每一个类或接口的常量池的运行时表示形式，在类和接口被加载到JVM后，对应的运行时常量池就被创建出来。当然并非Class文件常量池中的内容才能进入运行时常量池，在运行期间也可将新的常量放入运行时常量池中，比如String的intern方法。<br> 在JVM规范中，没有强制要求方法区必须实现垃圾回收。很多人习惯将方法区称为“永久代”，是因为HotSpot虚拟机以永久代来实现方法区，从而JVM的垃圾收集器可以像管理堆区一样管理这部分区域，从而不需要专门为这部分设计垃圾回收机制。不过自从JDK7之后，Hotspot虚拟机便将运行时常量池从永久代移除了。</p><hr><p>特别感谢<a href="http://www.cnblogs.com/dolphin0520/" target="_blank" rel="noopener">@海子</a></p>]]></content>

<p> MySQL中没有Rank排名函数，当我们需要查询排名时，只能使用MySQL数据库中的基本查询语句来查询普通排名。尽管如此，可不要小瞧基础而简单的查询语句，我们可以利用其来达到Rank函数一样的高级排名效果。</p>
<p>在这里我用一个简单例子来实现排名的查询：</p>
<p>首先我们先创建一个我们需要进行高级排名查询的<code>players</code>表，<br>

<content type="html"><![CDATA[<h4 id="前言"><a href="#前言" class="headerlink" title="前言"></a>前言</h4><p>Android采用的是java语言进行开发，但是Android系统有自己的虚拟机Dalvik和ART,代码编译最终不是采用的java的class，而是使用的smali。我们反编译得到的代码，jar的话可能很多地方无法正确的解释出来，如果我们反编译的是smali则可以正确的理解程序的意思。因此，我们有必要熟悉smali语法。<br><a id="more"></a></p><h4 id="关键字"><a href="#关键字" class="headerlink" title="关键字"></a>关键字</h4><p>.field private isFlag:z — 定义变量<br>.method — 方法<br>.parameter — 方法参数<br>.prologue — 方法开始<br>.line 12 —

对象赋值<br>iget-object — 调用对象<br>invoke-static — 调用静态函数</p><h4 id="数据类型"><a href="#数据类型" class="headerlink" title="数据类型"></a>数据类型</h4><p>java里面包含两种数据类型，基本数据类型和引用类型(包括对象)，同时映射到smali也是有这两大类型。</p><p><strong>基本数据类型</strong></p><ul><li>B — byte</li><li>C — char</li><li>D — double (64 bits)</li><li>F —

id="寄存器与变量"><a href="#寄存器与变量" class="headerlink"

p0</code>(this)<br><code>v3 p1</code>第一个参数<br><code>v4 p2</code>第二个参数<br><code>v5 p3</code>第三个参数</p></blockquote><p>当然，如果是静态方法的话就只有5个寄存器了，不需要存this了。<br><code>.registers</code>使用这个指令指定方法中寄存器的总数<br><code>.locals</code>使用这个指定表明方法中非参寄存器的总数，放在方法的第一行。</p><h4 id="方法和字段"><a href="#方法和字段"

<content type="html"><![CDATA[<p><img src="/assets/blogImg/baiduip/baiduip-1.png" class="img-center-normal"><br>如上图，就是现在打开下面的百度高精度IP定位服务的API首页的提示。<br><del>API首页：<a href="http://lbsyun.baidu.com/index.php?title=webapi/high-acc-ip" target="_blank" rel="noopener">http://lbsyun.baidu.com/index.php?title=webapi/high-acc-ip</a></del></p><h3 id="ip定位历史"><a href="#ip定位历史" class="headerlink" title="ip定位历史"></a>ip定位历史</h3><p>关于IP定位，最早是通过运营商实现，每个运营商申请到的ip段，在某个范围内使用。<br>因此早期只能是国家为单位的基础数据。<br>对于比较大的国家，就进一步划分，比如，中国某通讯公司（不打广告），固定将某些ip分配某些机房使用，而这些机房则具备地域属性，因此就可以知道某些ip的位置是哪个省市区。<br>在进一步，网上有种测算路由的方式进行定位，就是由大范围逐个跳转，跟踪路由。从而对比找出ip所在的小范围。<br><a id="more"></a></p><h3 id="前提条件"><a href="#前提条件" class="headerlink" title="前提条件"></a>前提条件</h3><p>如今，网络铺设已经有个相当多的特性，比如：<br>A.国内的某大运营商，ip资源够用，直接给用户分配公网ip。我以前就在这种网络下用动态域名工具玩过网站。<br>B.部分运营上为了缓解ip资源不足问题，某个大范围使用代理转发方式，给到用户的是私网ip，用户最终用代理的ip池的ip访问公网。<br>C.电话运营商，ip资源利用率过低，几乎是一个省份用一个ip池进行代理给用户的手机网络上网</p><h3 id="延伸价值"><a href="#延伸价值" class="headerlink" title="延伸价值"></a>延伸价值</h3><p>随着<a href="http://lib.csdn.net/base/hadoop" target="_blank" rel="noopener">大数据</a>的发展，百度做了大数据匿名收集数据，数据实时分析。因此可以将手机收集到的精准GPS数据和当前所用IP数据成对上报给后端服务器，运算过之后，就可以得出某个IP的分布范围数据。<br>误差说明：<br>对于上述A的情况，精确度可以达到几十米<br>对于上述B的情况，可能得覆盖一个城市的范围<br>对于上述C的情况，往往是一个省份的误差程度<br>因此，对于有线宽带用户，分配了相对固定的公网IP，用户在这个线路下有放置了wifi无线路由器，wifi下有接入了手机用户，手机里运行了百度的服务，比如百度地图，或者百度地图SDK。<br>其定位精度就可以达到几十米范围。对于这种数据，只有bat这种大头才能实现的了这个规模的数据手机，因此准确度几乎无法被超越，更大的互联网公司除外</p><h3 id="定位分析"><a href="#定位分析" class="headerlink" title="定位分析"></a>定位分析</h3><p>目前百度定位提供了WIFI,基站，GPS等多种定位方式，适用于室内、室外多种定位场景，具有出色的定位性能：定位精度高(其实我是想吐槽的)、覆盖率广、网络定位请求流量小、定位速度快。<br><img src="/assets/blogImg/baiduip/baiduip-2.png" class="img-center-normal"><br>众所周知，通过IP地址我们只能查到某一个市级城市的宽带服务商所在地。<br>但是，百度高精度定位却能产生近乎30m内的定位精度，这是为什么呢？</p><h3 id="百度高精度定位产生"><a href="#百度高精度定位产生" class="headerlink" title="百度高精度定位产生"></a>百度高精度定位产生</h3><p>百度官方文档显示：2016年8月26日，高精度IP定位服务API正式上线。</p><p> 百度高精度IP定位服务，其根本来源于百度匿名收集服务，它的源头则是：手机位置服务。当然，不排除百度其他应用的sdk，百度的其他应用如百度地图，也进行了这个匿名收集服务，至少百度收集这些数据并非出于泄露隐私目的，毕竟这项数据单方面来说是脱敏的，就好比是网络上一张盖住脸的裸体照片。但是，大数据发展导致我们可以用各个数据源去拼凑一个完整画像，有意无意导致一个泄露隐私的结果。<br> 因此百度在接到投诉后，首先将高精度 IP 定位接口的配额大幅下调，其次，很快就关停了新用户开通这项服务。<br> 在百度高精度IP定位服务刚上线的 2016 年 9 月、10月，那时候百度给的的配额还相对较高，公开申请：<br>认证企业开发者10W 次 /天，认证个人开发者1W 次 /天，非认证用户通过手机验证1k 次 /天。<br> 但是不确定在10月份或11月份某一天，百度直接下调到：<br>认证企业开发者300次/天，认证个人开发者100次/天，非认证用户数据不详。<br> 然而在12月10号前百度撤销了官方api文档，并停止了该服务的ak权限的申请，之前已经申请了的权限的ak仍可继续使用。推测原因是这项功能推出后，被太多人用来达成不良目的所导致（例如定位QQ，微信，陌陌等社交账号所在位置）。然而像类似于任天堂《Pokemon Go》这款LBS-AR游戏并没有很好地去使用这一服务。</p><h3 id="何去何从"><a href="#何去何从" class="headerlink" title="何去何从"></a>何去何从</h3><p> 针对现状来看，百度的这项服务，目前推测有2个方向：<br>1，关停（停止新接入或者整个服务对外关停）。<br>2，整顿权限（以更严格的审核方式对外提供）<br><strong>更新：2017年7月起，开发者陆续收到百度终止高精度IP定位服务API的通知邮件。<br>至此，百度高精度定位服务正式退出历史舞台。<br>原文：</strong></p><blockquote><p>亲爱的开发者，您好！<br> 我们很抱歉的通知您，目前您正在使用的「高精度IP定位服务API，后文简称本服务」，由于国家《网络安全法》等法律法规的要求，及出于保护用户权益和安全性的考量，我们将终止您对「本服务」的使用权限。具体终止时间为2017年7月28日。如有疑问，可发送邮件到<a href="mailto:mapapi@baidu.com" target="_blank"

<content

id="more"></a><p>对于Android编程我们知道分为SDK编程和NDK编程，当然Android签名校验也都是通过SDK或NDK来实现的。SDK编程也就是我们通常所说的java端的即编译出来的classes.dex静态校验，NDK编程也就是C / C++端的即编译出来的*.so动态加载的校验。</p><p>总之，<br>Java层一般通过getPackageManager().getPackageInfo.signatures来获取签名信息。<br>NDK层一般调用Native方法/DLL/Lua脚本等通过获取Java的context/Activity对象，动态JNI反射调用getPackageInfo等来获取签名。</p><p>好了，话不多说，切入正题。</p><p>群里聊天，小伙伴找我去除某款图像处理软件的广告，介于此软件已一年未更新，且互联网上出现的修改版均无法使用。。。。那么。。开搞。。。。</p><p>apk重签名，闪退，断定有签名校验。<br>直接拖入AndroidKiller大法，一段等待之后反编译完毕。</p><p>因为没有错误提示，那么对整个项目搜索<br><figure

src="/assets/blogImg/idasignature/idasignature-5.png"></p><p>搜索<code>signature</code> 勾选上<code>Find all occurences</code><br><img src="/assets/blogImg/idasignature/idasignature-6.png"></p><p>搜索完毕，没什么说的，妥妥的在5个Function中找到<br><img src="/assets/blogImg/idasignature/idasignature-7.png"></p><p>双击第一个Function跳过去<br><img src="/assets/blogImg/idasignature/idasignature-8.png"></p><p>右键选择<code>Graph view</code>切换图形视图<br><img src="/assets/blogImg/idasignature/idasignature-9.png"></p><p>通过视图，我们找到了一个关键跳转（可以通过Ctrl+鼠标滑轮来调整视图缩放）<br><img src="/assets/blogImg/idasignature/idasignature-10.png"></p><p>右键选择<code>Text view</code>切换回文本视图<br><img src="/assets/blogImg/idasignature/idasignature-11.png"></p><p>其对应的就是文本视图界面中的<br><img src="/assets/blogImg/idasignature/idasignature-12.png"></p><p>F5看一下C语言代码（这样做的前提是，你的IDA Pro必须支持F5功能）<br><img src="/assets/blogImg/idasignature/idasignature-13.png"></p><p>通过分析C代码我们得知这里将获取到的签名信息进行判断，<br>由此我们得知BEQ指令就是问是不是不相等，不相等那么为真的意思。而查阅之后印证了我们的判断：</p><blockquote><p>BEQ指令是“相等（或为0）跳转指令”，<br>BNE指令是“不相等（或不为0）跳转指令”，<br>B指令是“无条件跳转指令”，<br>CBZ 指令是“比较，为零则跳转”，<br>CBNZ指令是“比较，为非零则跳转”。</p></blockquote><p>通过工具，我们发现：</p><blockquote><p>BNE跳转指令对应的HEX机器码是D1，<br>BEQ跳转指令对应的HEX机器码是D0，<br>CBZ跳转指令对应的HEX机器码是B1，<br>CBNZ跳转指令对应的HEX机器码是B9。</p></blockquote><p>回过头来，简单的看一下指令流程，BEQ下面是exit方法，则说明不能跳转指令为签名验证失败，反向逻辑一下，把BEQ指令改为相反的BNE指令即可。</p><p>修改方式一：我们可以在HEX界面右键<code>Edit</code>将D0改为D1，再右键<code>Apply changes</code>来保存修改，需要注意的是，在IDA中的修改仅仅是为了验证我们修改的正确与否，源文件并不会改变，我们可以定位修改位置后再利用010Editor、UltraEdit等编辑器来对源文件进行修改。</p><p><img src="/assets/blogImg/idasignature/idasignature-14.png"></p><p><img src="/assets/blogImg/idasignature/idasignature-15.png"></p><p>验证发现BEQ已经修改为BNE<br><img src="/assets/blogImg/idasignature/idasignature-16.png"></p><p>修改方式二：当然，强大的IDA怎么可能没有修改后保存的功能呢。我们可以使用Edit->Patch Program菜单来方便的进行修改保存。<br>（需要注意的是，Patch Program菜单是GUI版本的IDA的一项隐藏功能，用户需要编辑idagui.cfg配置文件才能激活该菜单， 编辑IDA配置文件cfg目录下的idagui.cfg，修改DISPLAY_PATCH_SUBMENU=YES，重启IDA即可）</p><p>首先我们在IDA View 中显示十六进制机器码, Options -> General -> Disassembly -> Number of opcode bytes = 8<br><img src="/assets/blogImg/idasignature/idasignature-17.png"></p><p>然后Edit->Patch Program->Change byte<br><img src="/assets/blogImg/idasignature/idasignature-18.png"></p><p>将D0改为D1，OK<br><img src="/assets/blogImg/idasignature/idasignature-19.png"></p><p>然后Edit->Patch Program->Apple patches to input file<br><img src="/assets/blogImg/idasignature/idasignature-20.png"></p><p>OK即可<br><img src="/assets/blogImg/idasignature/idasignature-21.png"></p><p>同理，我们找到其他方法中的跳转点来进行反向逻辑，保存so文件，覆盖原文件，回编译，安装。完美运行~</p><p>具体去广告过程不是本次重点所以就不再过多陈述，另外说一点sdk23以上的权限请求问题，当过完签名校验并去除广告后，当要读取图库照片来进行处理时，原本应该进行文件存储的权限请求，但是此时却FC了，当我手动给予权限后才正常。想想就苦恼，让人安装后边还得手动给权限。。。。</p><p>不行，我们得解决了它。我们知道如果APP运行在Android 6.0或以上版本的手机，并且target sdk>=23，那么在使用一些相对敏感的权限时，需要征求用户的许可。比如读写sdcard，摄像，联系人信息等。 这是Android 6.0，在原有的AndroidManifest.xml声明权限的基础上，新增了运行时权限动态检测。不过为了兼容性，Android为targetSdkVersion小于23的应用默认授予了所申请的所有权限，所以如果你以前的APP设置的targetSdkVersion低于23，也能正常使用。等于或者大于23，则必须 request permission,否则会崩溃闪退。</p><p>当我们用apktool反编译后破坏了complierSdkversion的值，我们可以在apktool.yml中的sdkInfo中添加<code>complierSdkversion: '23'</code>，或者干脆我们索性将<code>targetSdkVersion</code>设置为<code>22</code>，默认给它权限就好了。(complierSdkversion的值和targetSdkVersion的值一定要统一，不然会出错)</p><p>修改apktool.yml文件完美解决~<br><img src="/assets/blogImg/idasignature/idasignature-22.png"></p><p><strong>步骤回顾：<br>1、反编译apk<br>2、利用关键词查找签名调用<br>3、IDA静态调试分析<br>4、了解arm指令详情作用<br>5、修改逻辑跳转绕过签名校验</strong></p><p><strong>总结：<br>本文主要介绍破解安卓NDK端native方法动态JNI反射so文件签名校验的方法。</strong></p>]]></content>

<p><strong>核心：破解安卓NDK端native方法动态JNI反射的so文件签名校验</strong></p>
<p>分析之前，关于Android的签名机制就略过啦，先简单恶补一下Android签名校验的方式，方便小白理解。</p>
<p>在讲签名校验的方式前，需要先明确dex文件校验和签名校验：<br>1、将apk以压缩包的形式打开删除原签名后，再签名，安装能够正常打开，但是用IDE工具反编译(classes.dex)后再二次打包，却出现非正常情况的，如：闪退/弹出非正版提示框。可以确定是dex文件校验。<br>2、将apk以压缩包的形式打开删除原签名再签名，安装之后打开异常的，则基本可以断定是签名检验。如果在断网的情况下同样是会出现异常，则是本地的签名检验。如果首先出现的是提示网络没有连接，则是服务器端的签名校验。</p>

<title>使用渐进式 JPEG 来提升用户体验</title>
<link href="http://inplus.top/archives/optimizejpeg/"/>
<id>http://inplus.top/archives/optimizejpeg/</id>
<published>2016-12-01T01:56:40.000Z</published>

<content type="html"><![CDATA[<p> 网络上那些色色的照片都是<code>.jpg</code>格式的（“色色”指的是色彩斑斓的意思 /手动抠鼻/）。不知诸位有没有注意到，这些<code>.jpg</code>格式的图片在呈现的时候，有两种方式，一种是自上而下扫描式的，还有一种就是先是全部的模糊图片，然后逐渐清晰(就像GIF格式的交错显示)。</p><p> JPEG文件有两种保存方式，分别是<em>Baseline JPEG（基准式）</em>和<em>Progressive JPEG（渐进式）</em>。两种格式有相同尺寸以及图像数据，它们的扩展名也是相同的，唯一的区别是二者显示的方式不同。<br><a id="more"></a><br><strong>Baseline JPEG</strong><br> 这种类型的JPEG文件存储方式是按从上到下的扫描方式，把每一行顺序的保存在JPEG文件中。打开这个文件显示它的内容时，数据将按照存储时的顺序从上到下一行一行的被显示出来，直到所有的数据都被读完，就完成了整张图片的显示。如果文件较大或者网络下载速度较慢，那么就会看到图片被一行行加载的效果，这种格式的JPEG没有什么优点，因此，一般都推荐使用<em>Progressive JPEG</em>。<br><img src="/assets/blogImg/optimizejpeg/optimizejpeg-1.gif"></p><p><strong>Progressive JPEG</strong><br> 和<em>Baseline JPEG</em>一遍扫描不同，<em>Progressive JPEG</em>文件包含多次扫描，这些扫描顺寻的存储在JPEG文件中。打开文件过程中，会先显示整个图片的模糊轮廓，随着扫描次数的增加，图片变得越来越清晰。这种格式的主要优点是在网络较慢的情况下，可以看到图片的轮廓知道正在加载的图片大概是什么。在一些网站打开较大图片时，你就会注意到这种技术。<br><img src="/assets/blogImg/optimizejpeg/optimizejpeg-2.gif"></p><p>#####让我们来对比一下：<br> 渐进式图片带来的好处是可以让用户在没有下载完图片就可以看到最终图像的大致轮廓，一定程度上可以提升用户体验。（瀑布流的网站建议还是使用基准式的）<br><img src="/assets/blogImg/optimizejpeg/optimizejpeg-3.jpg"><br> 另外渐进式的图片的大小并不会和基本的图片大小相差很多，有时候可能会比基本图片更小。渐进式的图片的缺点就是吃用户的CPU和内存，不过对于现在的电脑来说这点图片的计算并不算什么。</p><p><strong>下载呈现速度</strong><br> 一个名叫<a href="http://htmlhive.com/" target="_blank" rel="noopener">Ann Robson</a>的人，最近对各个浏览器下渐进式图片呈现做了测试。<br>下图为FireFox浏览器下呈现速度的对比图：<br><img src="/assets/blogImg/optimizejpeg/optimizejpeg-4.jpg"><br> 当大图轮廓加载OK的时候，小图最后一个乳猪还没有出世面；而基准式乳猪图还没有开始加载！显然，罗伯森是想告诉我们，渐进式JPEG下载更快。</p><p>下表为其在各个浏览器下测试的结果：<br><img src="/assets/blogImg/optimizejpeg/optimizejpeg-5.jpg"></p><p>结论很简单，Chrome + Firefox + IE9浏览器下，渐进式图片加载更快，而且是快很多，至于其他浏览器，与基准式图片的加载一致，至少不会拖后腿。</p><p><a href="http://www.webmonkey.com/author/luxagraf/" target="_blank" rel="noopener">Scott Gilbertson</a>对渐进式图片有其他的补充：<br>1.你永不知道基准式图片内容，除非他完全加载出来。<br>2.渐进式图片一开始大小框架就定好，不会像基准式图片一样，由于尺寸未设定而造成回流——提高的渲染性能。<br>3.渐进式图片也有不足，就是吃CPU吃内存。<br>ps: png图片也是可以渐进式呈现的</p><p>内容就是这些，权衡使用在你手。一般而言，大尺寸图片建议使用渐进式JPEG。</p><p>#####那么怎么将图片保存为或者转化为Progressive JPEG呢？<br>方法如下：</p><p><strong>1、PhotoShop</strong><br>在photoshop中有“存储为web所用格式”，打开后选择“连续”就是渐进式JPEG。<br><img src="/assets/blogImg/optimizejpeg/optimizejpeg-6.jpg"></p><p><strong>2、Linux</strong><br>检测是否为<em>progressive jpeg</em>： identify -verbose filename.jpg | grep Interlace<br>（如果输出 None 说明不是progressive jpeg；如果输出 Plane 说明是 progressive jpeg。）<br>将<em>basic jpeg</em>转换成<em>progressive jpeg</em>：> convert infile.jpg -interlace Plane outfile.jpg</p><p><strong>3、PHP</strong><br>使用<a href="http://php.net/manual/en/function.imageinterlace.php" target="_blank" rel="noopener">imageinterlace</a>和<a href="http://www.php.net/manual/en/function.imagejpeg.php" target="_blank"

<p> 网络上那些色色的照片都是<code>.jpg</code>格式的（“色色”指的是色彩斑斓的意思 /手动抠鼻/）。不知诸位有没有注意到，这些<code>.jpg</code>格式的图片在呈现的时候，有两种方式，一种是自上而下扫描式的，还有一种就是先是全部的模糊图片，然后逐渐清晰(就像GIF格式的交错显示)。</p>
<p> JPEG文件有两种保存方式，分别是<em>Baseline JPEG（基准式）</em>和<em>Progressive JPEG（渐进式）</em>。两种格式有相同尺寸以及图像数据，它们的扩展名也是相同的，唯一的区别是二者显示的方式不同。<br>

<content type="html"><![CDATA[<p><img src="/assets/blogImg/hexo/hexo-0.png" class="img-left-logo"></p><hr><h1 id="前言"><a href="#前言" class="headerlink" title="前言"></a>前言</h1><p>习惯自己写Blog的朋友一定不会陌生Wordpress，或许也曾在新浪博客和QQ空间留过脚印，但静心认真思考一下，似乎我们又总是向往更加简单自由的写作方式。GitHub给我们提供了一个无限的空间，我们需要珍惜使用，而Hexo的出现从某种意义上来说代替了Jekyll，让我们可以更专注于写作本身。</p><blockquote><p><strong>喜欢写Blog的人，会经历三个阶段。</strong><br>第一阶段，刚接触Blog，觉得很新鲜，试着选择一个免费空间来写。<br>第二阶段，发现免费空间限制太多，就自己购买域名和空间，搭建独立博客。<br>第三阶段，觉得独立博客的管理太麻烦，最好在保留控制权的前提下，让别人来管，自己只负责写文章。</p></blockquote><blockquote><p>大多数Blog作者，都停留在第一和第二阶段，因为第三阶段不太容易到达：你很难找到俯首听命、愿意为你管理服务器的人。</p></blockquote><blockquote><p>但是六年前，情况出现变化，一些程序员开始在GitHub网站上搭建blog。他们既拥有绝对管理权，又享受GitHub带来的便利—-不管何时何地，只要向主机提交commit，就能发布新文章。更妙的是，这一切还是免费的，GitHub提供无限流量，世界各地都有理想的访问速度。</p></blockquote><blockquote><p>今天，我就来示范如何在GitHub上搭建Blog，你可以从中掌握GitHub的Pages功能，以及Hexo软件的基本用法。更重要的是，你会体会到一种建立网站的全新思路。</p></blockquote><hr><a id="more"></a><h1 id="概要"><a href="#概要" class="headerlink" title="概要"></a>概要</h1><h3 id="GitHub-Pages-是什么？"><a href="#GitHub-Pages-是什么？" class="headerlink" title="GitHub Pages 是什么？"></a>GitHub Pages 是什么？</h3><p>如果你对编程有所了解，就一定听说过<a href="https://github.com/" target="_blank" rel="noopener">GitHub</a>。它号称程序员的Facebook，有着极高的人气，许多重要的项目都托管在上面。<br>简单说，它是一个具有版本管理功能的代码仓库，每个项目都有一个主页，列出项目的源文件。</p><p>但是对于一个新手来说，看到一大堆源码，只会让人头晕脑涨，不知何处入手。他希望看到的是，一个简明易懂的网页，说明每一步应该怎么做。因此，GitHub就设计了<a href="http://pages.github.com/" target="_blank" rel="noopener">Pages功能</a>，允许用户自定义项目首页，用来替代默认的源码列表。</p><p><strong>所以，GitHub Pages可以被认为是用户编写的、托管在GitHub 上的静态网页。</strong></p><p>GitHub 提供模板，允许<a href="https://help.github.com/articles/creating-pages-with-the-automatic-generator" target="_blank" rel="noopener">站内生成</a>网页，但也允许用户自己编写网页，然后上传。有意思的是，这种上传并不是单纯的上传，而是会经过Hexo或Jekyll等程序的再处理。</p><h3 id="什么是Hexo？"><a href="#什么是Hexo？" class="headerlink" title="什么是Hexo？"></a>什么是Hexo？</h3><p><a href="https://hexo.io/" target="_blank" rel="noopener">Hexo</a> 是一个快速、简洁且高效的基于Node.js的博客框架。Hexo 使用 Markdown（或其他渲染引擎）解析文章，在几秒内，即可利用靓丽的主题生成静态网页。作者是来自台湾的<a href="https://github.com/tommy351/hexo" target="_blank" rel="noopener">@tommy351</a>。</p><blockquote><p>A fast, simple & powerful blog framework, powered by Node.js.</p></blockquote><p>类似于jekyll、Octopress、Wordpress，我们可以用Hexo创建自己的博客，托管到github、Heroku或Coding上，绑定自己的域名，用markdown写文章。<a href="http://viosay.github.io/" target="_blank" rel="noopener">本博客</a>即使用hexo创建并托管在github上。</p><h3 id="为什么要用hexo"><a href="#为什么要用hexo" class="headerlink" title="为什么要用hexo"></a>为什么要用hexo</h3><blockquote><p>不可思议的快速 ─ 只要一眨眼静态文件即生成完成<br>支持 Markdown<br>仅需一道指令即可部署到 GitHub Pages 和 Heroku<br>已移植 Octopress 插件<br>高扩展性、自订性<br>兼容于 Windows, Mac & Linux</p></blockquote><ul><li>易用。不仅部署简单，平时使用中仅需要<code>hexo new</code> <code>hexo generate</code> <code>hexo server</code> <code>hexo deploy</code>四个命令。不像Jekyll需要很多繁琐的<code>git</code>命令。</li><li>轻。文件少、小，易理解，方便自定义。</li><li>用户多。虽然赶不上Jekyll和Octopress，但遇到什么问题都能搜索到答案，或者找到同样使用hexo的用户进行参考和咨询。</li></ul><h3 id="谁能使用hexo"><a href="#谁能使用hexo" class="headerlink" title="谁能使用hexo"></a>谁能使用hexo</h3><p>这是一个免费开源的博客程序，任何人都可以使用和修改。但是不同于wordpress，hexo由于需要使用<em>Github,Git,Markdown,Node.js</em>这样的工具，好多插件、widget都需要自己安装、设置。所以适合那些<strong>有一定计算机基础，喜欢折腾</strong>的人。但是，不要恐惧，只要跟着本教程走，就能很方便地让自己的博客”飞起来”。</p><h3

<h1 id="前言"><a href="#前言" class="headerlink" title="前言"></a>前言</h1><p>习惯自己写Blog的朋友一定不会陌生Wordpress，或许也曾在新浪博客和QQ空间留过脚印，但静心认真思考一下，似乎我们又总是向往更加简单自由的写作方式。GitHub给我们提供了一个无限的空间，我们需要珍惜使用，而Hexo的出现从某种意义上来说代替了Jekyll，让我们可以更专注于写作本身。</p>
<blockquote>
<p><strong>喜欢写Blog的人，会经历三个阶段。</strong><br>第一阶段，刚接触Blog，觉得很新鲜，试着选择一个免费空间来写。<br>第二阶段，发现免费空间限制太多，就自己购买域名和空间，搭建独立博客。<br>第三阶段，觉得独立博客的管理太麻烦，最好在保留控制权的前提下，让别人来管，自己只负责写文章。</p>
</blockquote>
<blockquote>
<p>大多数Blog作者，都停留在第一和第二阶段，因为第三阶段不太容易到达：你很难找到俯首听命、愿意为你管理服务器的人。</p>
</blockquote>
<blockquote>
<p>但是六年前，情况出现变化，一些程序员开始在GitHub网站上搭建blog。他们既拥有绝对管理权，又享受GitHub带来的便利—-不管何时何地，只要向主机提交commit，就能发布新文章。更妙的是，这一切还是免费的，GitHub提供无限流量，世界各地都有理想的访问速度。</p>
</blockquote>
<blockquote>
<p>今天，我就来示范如何在GitHub上搭建Blog，你可以从中掌握GitHub的Pages功能，以及Hexo软件的基本用法。更重要的是，你会体会到一种建立网站的全新思路。</p>

<content type="html"><</code>这样的语法即可插入链接，<br>使用<code></code>这样的语法即可插入图片。<br>例如：<br><figure class="highlight markdown"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">[<span class="string">寻沫小栈</span>](<span class="link">http://viosay.github.io</span>)</span><br></pre></td></tr></table></figure></p><figure class="highlight markdown"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">![<span class="string">我的头像</span>](<span class="link">http://viosay.github.io/assets/img/head.jpg</span>)</span><br></pre></td></tr></table></figure><p>注意：插入图片的语法和链接的语法很像，只是前面多了一个<code>!</code>。</p><p>另：Markdown支持以比较简短的自动链接形式来处理网址和电子邮件信箱，只要是用尖括号<code><</code>和<code>></code>包起来，Markdown 就会自动把它转成链接。一般网址的链接文字就和链接地址一样。<br>例如：<br><figure class="highlight groovy"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><<span class="string">http:</span><span class="comment">//example.com/></span></span><br></pre></td></tr></table></figure></p><h3 id="5、粗体与斜体"><a href="#5、粗体与斜体" class="headerlink" title="5、粗体与斜体"></a>5、粗体与斜体</h3><p>Markdown的粗体和斜体也非常简单，用两个星号<code>**</code>或两个下划线<code>__</code>包裹一段文本就是粗体的语法，用一个星号<code>*</code>或一个下划线<code>_</code>包裹一段文本就是斜体的语法。<br>例如：<br><figure class="highlight asciidoc"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">*<span class="strong">*这里是粗体*</span><span class="strong">*</span></span><br></pre></td></tr></table></figure></p><figure class="highlight asciidoc"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"><span class="strong">*这里是斜体*</span></span><br></pre></td></tr></table></figure><h3 id="6、分割线与删除线"><a href="#6、分割线与删除线" class="headerlink" title="6、分割线与删除线"></a>6、分割线与删除线</h3><p>分割线的语法只需要另起一行，连续输入三个减号<code>---</code>、下划线<code>___</code>、星号<code>***</code>即可。<br>删除线的语法只需用两个波浪号<code>~~</code>包裹一段文本即可。<br>例如：<br><figure class="highlight yaml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span

class="line">~~本段文字被删除线拦截~~</span><br></pre></td></tr></table></figure><p>注意：对于分割线，行内不得有任何其他字符。</p><h3 id="7、代码句和代码块"><a href="#7、代码句和代码块" class="headerlink" title="7、代码句和代码块"></a>7、代码句和代码块</h3><p>如果你是个程序猿，需要在文章里优雅的引用代码框，在 Markdown 下实现也非常简单。需要引用代码时，如果引用的代码语句只有一段，不分行，可以用一个重音符`将代码语句包裹起来。如果引用的语句为多行的代码块，可以将三个重音符```置于这段代码的首行和末行来包裹代码块。<br>例如：<br><figure class="highlight applescript"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">`hello <span class="built_in">word</span>代码句`</span><br></pre></td></tr></table></figure></p><p><img src="/assets/blogImg/markdown/markdown-1.png"><br>注意：在代码块中使用<code>tab</code>键即可进行缩进。</p><h3 id="8、表格"><a href="#8、表格" class="headerlink" title="8、表格"></a>8、表格</h3><p>相对于那些简单的语法，Markdown表格则较为繁琐和累人。<br>例如：<br><figure class="highlight ruby"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br></pre></td><td class="code"><pre><span

<content type="html"><![CDATA[<p>『摄影师』Andrew Whyte：带着乐高小人去旅行</p><p> 乐高玩具在全世界都拥有著无数粉丝，与之相关的《The Lego Movie》也是横扫世界各地的电影票房。当然，乐高玩具人人会玩，可要是想以这些小方块创作出壹些艺术作品的话可就不是那么容易了。如果你找不到什么灵感的话，那不如来看看摄影师 Andrew Whyte 利用乐高玩偶创造的「Legography」系列作品吧。<br> Andrew Whyte 擅长利用长曝光等方式创作变化多端的微观风格摄影作品。在「Legography」系列作品中，他通过技术手段巧妙地将玩偶所处的微观环境以拟人化的形态呈现在大家眼前。玩偶好似壹个现实世界中的真实身影，在不同的场景中展开各种离奇的故事。<br> 想要了解更多有关「Legography」作品的朋友可以访问 Andrew Whyte 的官方网站。</p><p><img src="/assets/blogImg/legotwo/legotwo-1.jpg" class="img-left-suitable"><br><a id="more"></a></p><blockquote><p>手机镜头的视角与相机大不相同，为了达到目标，作者尝试了19次才把相机玩具扔到了正确地位置。</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-2.jpg" class="img-left-suitable"></p><blockquote><p>iPhone 4s在低光照的情况下画质不佳，即使这样，这张黄昏时的照片还是可以接受的</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-3.jpg" class="img-left-suitable"></p><blockquote><p>很多时候乐高摄影需要趴在地上完成，作者因此也成为了其他游客的拍摄对象</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-4.jpg" class="img-left-suitable"></p><blockquote><p>作者收集了许多腿、躯干、帽子的零件，能帮助小人偶进行换装</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-5.jpg" class="img-left-suitable"></p><blockquote><p>天气不好的时候拍摄仍没有停止，作者还为小人偶加了件雨衣</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-6.jpg" class="img-left-suitable"></p><blockquote><p>有时为了拍摄与野生动物相关的照片，作者遭遇了器械的损坏，甚至还受了伤</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-7.jpg" class="img-left-suitable"></p><blockquote><p>拍摄于朴茨茅斯，英国唯一的岛屿城市。</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-8.jpg" class="img-left-suitable"></p><blockquote><p>由于人偶的表情不能变化，所以大部分的照片都避开了正面，这是唯一的一张人偶自拍照</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-9.jpg" class="img-left-suitable"></p><blockquote><p>SlowShutter实现了作者对于长曝光app的期望，其对焦与曝光锁在黑暗中相当有用</p></blockquote><p><img src="/assets/blogImg/legotwo/legotwo-10.jpg" class="img-left-suitable"></p><blockquote><p>天气一般时，往往尝试了各种滤镜后也不能获得满意的效果。但有时等到第二天早上，就能拍到不需要后期的满意照片</p></blockquote><p> 英国摄影师Andrew Whyte专长于戏剧灯光艺术与对于夜空的长时间曝光，但他最近的一些工作相当引人注目——他为一位一英寸高的小小摄影师拍摄了一组照片。Whyte花了超过一年的时间拍摄了这组称为“乐高摄影师”的系列作品，其中的主角是一个手拿黑色相机的乐高积木人偶。这个小人偶和Whyte一起旅行，一起看日出，一起在伦敦游览。</p><p><img src="/assets/blogImg/legotwo/legotwo-11.jpg" class="img-left-suitable"></p><p> 考虑到便携性，这组乐高摄影是由iPhone完成的，从最初的4s到现在的5s。Whyte使用一款称为645 Pro的应用来获得更多的手动拍摄选项，然后使用Snapseed特效进行后期后上传到乐高摄影的Facebook页面。“作为对于手机摄影的探索，这个项目相当具有启发性，我知道了我能够在几乎任何地方都能用手机拍出高水准的作品。”Whyte说道。另外他还有一些其他的长曝光摄影作品。</p><p><img src="/assets/blogImg/legotwo/legotwo-12.jpg" class="img-left-suitable"></p><p> 英国摄影师Andrew Whyte是一位擅长在弱光环境下创作的职业摄影师。他认为弱光环境下的摄影可以让“光线”和“时间”这两种最具魅力的元素交织在一起。但是在他的整个摄影职业当中，有一个非常重要的摄影项目却并非专注于弱光环境的拍摄，而是一个以乐高玩具小人为主人公的系列作品——《Legography》。</p><p><img src="/assets/blogImg/legotwo/legotwo-13.jpg" class="img-left-suitable"></p><p> 作品中的玩具小人扮演了摄影师的角色，“他”用自己的相机去看世界，而我们也从照片中看到了“他”看到的世界，从作品中你甚至可以读出“他”的性格：执着、专注、勇敢，对摄影有一种热烈的追求，你也能从“他”观看世界的角度中感受到“他”的情绪：思念、好奇、陶醉、孤独……</p><p><img src="/assets/blogImg/legotwo/legotwo-14.jpg" class="img-left-suitable"></p><p> 类似于这样以玩具或者公仔作为摄影兴趣中心的作品相信大家也看过不少。这样的作品很容易具有故事性，也就很容易让我们进入画面，获得情景设置所要传达的感受。</p><p><img src="/assets/blogImg/legotwo/legotwo-15.jpg" class="img-left-suitable"></p><p> 值得一提的是，这个系列的作品均为手机拍摄，并用手机软件修图制作完成。</p><p><img src="/assets/blogImg/legotwo/legotwo-16.jpg" class="img-left-suitable"></p><p> 乐高不一定是小朋友们钟爱的玩具，很多大人也对乐高情有独钟。摄影师Andrew Whyte作为一名“乐高控”，走到哪都要带着他的“Legographer”，于是便有了这一系列照片。</p><p><img src="/assets/blogImg/legotwo/legotwo-17.jpg" class="img-left-suitable"></p><p> Andrew Whyte来自英国，“Legographer”大部分照片拍摄于英格兰南部的著名海滨城市朴茨茅斯。这一系列照片均出自iPhone 4s，拍摄软件为645 Pro Mark II，并经过Snapseed后期处理。这样的拍摄组合另很多人意外，其实Andrew有意想挑战一下手机的弱光拍摄效果，同时也可以达到在实战中提升自己拍摄水平的目的。毫无疑问，他的目的达到了。</p><p><img src="/assets/blogImg/legotwo/legotwo-18.jpg" class="img-left-suitable"></p><p> 英国摄影师Andrew Whyte用镜头记录乐高人偶的英国游记，透过“Mini摄影师”的角度重新看世界！</p><p><img src="/assets/blogImg/legotwo/legotwo-19.jpg" class="img-left-suitable"></p><p> 凭着一点玩心和创意，英国摄影师Andrew Whyte突发奇想，以乐高 (Lego) 小人为主角记录下了他眼中的英伦风光。这位身材小小的“摄影师”相当敬业，克服千难万险拍摄了落日、彩虹等一系列美丽风景。一起来看看吧！</p><p><img src="/assets/blogImg/legotwo/legotwo-20.jpg" class="img-left-suitable"></p><p> 其实，Andrew Whyte不仅为我们带来了一组创意十足的旅行摄影图集，还十分贴心地整理出拍摄这类照片运用的方法和一些注意事项，接下来是“带着乐高小人去旅行”教学篇！</p><p><img src="/assets/blogImg/legotwo/legotwo-21.jpg" class="img-left-suitable"></p><p> 给大家介绍了摄影师Andrew Whyte拍摄的“带着乐高小人去旅行”系列照片，这组照片给人眼前一亮的感觉。其实摄影师不但介绍了这些照片的拍摄背景和器材使用情况，更加难能可贵的是，还为大家总结出了5点拍摄类似专题的注意事项，希望大家看后能有所收获：</p><p><img src="/assets/blogImg/legotwo/legotwo-22.jpg" class="img-left-suitable"></p><p> 寻找一个有趣的故事：任何一个拍摄活动都有主题，这是大家首先要确定的事情。接下来就可以围绕这个主题开始拍摄，可以尝试不同的手法，控制好大场景中的人物比例、小范围的景深问题等。</p><p><img src="/assets/blogImg/legotwo/legotwo-23.jpg" class="img-left-suitable"></p><p> 低角度：有时候我们习惯了同一高度拍摄，却忘了低角度可能有令人意想不到的效果。就像这组照片，很多时候都是贴着水平线拍摄，这样的角度给人新鲜的感觉，把视角低下来没准就能看到另一个世界。</p><p><img src="/assets/blogImg/legotwo/legotwo-24.jpg" class="img-left-suitable"></p><p> 运用技巧弥补：手机拍摄有很大的局限性，但是运用一些小技巧完全可以弥补。例如手机在弱光环境下表现不尽如人意，可以运用手电等照明装置给主体打光;在阴雨天路面积水会反光，这时可以利用影子来遮挡，这样就可以解决光比大的问题了。</p><p><img src="/assets/blogImg/legotwo/legotwo-25.jpg" class="img-left-suitable"></p><p> 反复确定对焦点：刚刚提到了手机拍摄的局限性，所以在拍摄时需要反复确定对焦点，这样才能保证对焦准确。</p><p><img src="/assets/blogImg/legotwo/legotwo-26.jpg" class="img-left-suitable"></p><p> 善于使用App：这组照片使用了645 Pro Mark II和Snapseed，这两个软件搭配使用效果很好。但不意味着大家也要使用，只要运用自己习惯的App，在拍摄是最大限度的发挥其功效，就能拍出满意的照片。</p><p><img src="/assets/blogImg/legotwo/legotwo-27.jpg" class="img-left-suitable"></p><p><img src="/assets/blogImg/legotwo/legotwo-28.jpg" class="img-left-suitable"></p><p><img src="/assets/blogImg/legotwo/legotwo-29.jpg" class="img-left-suitable"></p><p><img src="/assets/blogImg/legotwo/legotwo-30.jpg" class="img-left-suitable"></p><p><img src="/assets/blogImg/legotwo/legotwo-31.jpg"
