数据解析的时候如果数据里有大括号就会出错需要修改为如下

[soitif]

protected static function _decryptMsg($body, $encodeKey)
    {
        $enc_msg = base64_decode($body);
        $aes_key = base64_decode($encodeKey . '=');
        $secure_key = substr($aes_key, 0, 32);
        $iv = substr($aes_key, 0, 16);
        $msg = openssl_decrypt($enc_msg, 'AES-256-CBC', $secure_key, OPENSSL_RAW_DATA, $iv);
        //$pattern = '/.*(\{.*\})/'; //原正则
        $pattern = "/[^\{]*(\{.*\})/i";
        $msg = preg_replace($pattern, '${1}', $msg);
        return $msg;
    }
