DeepSeek Chat API 文档

基础信息

• 基础URL: https://chat.deepseek.com
• 认证方式: Bearer Token (通过Authorization头部传递)

API端点

1. 获取聊天会话列表

GET /api/v0/chat_session/fetch_page?count={数量}

请求头:

Authorization: Bearer <你的token>
Accept: */*
Referer: https://chat.deepseek.com/
User-Agent: Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/132.0.0.0 Mobile Safari/537.36

查询参数:

• count: 要返回的会话数量

响应示例:

{
  "code": 0,
  "data": {
    "biz_data": {
      "chat_sessions": [
        {
          "id": "会话ID",
          "title": "会话标题",
          "updated_at": 时间戳
        }
      ]
    }
  }
}

2. 获取会话消息历史

GET /api/v0/chat/history_messages?chat_session_id={会话ID}

请求头:

Authorization: Bearer <你的token>
Accept: */*
Referer: https://chat.deepseek.com/a/chat/s/{会话ID}
User-Agent: Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/132.0.0.0 Mobile Safari/537.36

查询参数:

• chat_session_id: 要查询的会话ID

响应示例:

{
  "code": 0,
  "data": {
    "biz_data": {
      "messages": [
        {
          "content": "消息内容",
          "role": "user|assistant"
        }
      ]
    }
  }
}

使用流程

1. 首先调用/api/v0/chat_session/fetch_page获取所有会话列表
2. 对每个会话ID调用/api/v0/chat/history_messages获取详细消息
3. 将会话内容保存为标题.txt文件

完整示例代码

#!/bin/bash

# 获取所有会话
curl 'https://chat.deepseek.com/api/v0/chat_session/fetch_page?count=500' \
  -H 'Authorization: Bearer <你的token>' \
  -H 'User-Agent: Mozilla/5.0' > sessions.json

# 提取会话ID和标题
jq -r '.data.biz_data.chat_sessions[] | .id + " " + .title' sessions.json | while read id title; do
  # 获取会话历史
  curl "https://chat.deepseek.com/api/v0/chat/history_messages?chat_session_id=$id" \
    -H 'Authorization: Bearer <你的token>' \
    -H 'User-Agent: Mozilla/5.0' > "$title.json"
  
  # 转换为文本文件
  jq -r '.data.biz_data.messages[] | .role + ": " + .content' "$title.json" > "${title//\//_}.txt"
done

注意：将<你的token>替换为实际的Bearer Token，并确保已安装jq工具处理JSON数据。
