有道云笔记自动签到

主体步骤

1. 笔记本装fiddler；猎豹WiFi开热点；

2. 手机连接热点，WiFi设置代理-手动-主机为192.168.1.1，端口为8888；

3. 手机浏览器访问fiddler代理ip+端口，如猎豹WiFi是192.168.191.1:8888，安装fiddler证书到手机；否则app是不给联网的。

4. 抓app的包。

5. 分析app登录、签到时都干了什么。

具体实施

好，假设你已经做好了准备工作。

（1）第一步，device_open

当有道云笔记app打开时，app访问device_open，fiddler抓到的包：
注意返回的delusers数组，删除用户？怪吓人的。

上图是POST请求，下图是服务器返回（下同）。

把程序放在服务器上：



设置crontab例行任务

# signin.sh
cd /home/whuliss/Documents/
date >> signin_log
java SignIn >> signin_log
