[代码][Link 1]

## **一、流程** ##

1.  获取BaiDuID（[http://yun.baidu.com/][http_yun.baidu.com]）
2.  获取token（[https://passport.baidu.com/v2/api/?getapi&tpl=netdisk&apiver=v3][https_passport.baidu.com_v2_api_getapi_tpl_netdisk_apiver_v3]）
3.  完成登录。如果cookie里有BaiDuSS登录成功。
4.  好像如果要获取百度云数据还需要从其他链接更新cookie。

> 许多教程里有获取gid，UBI等数据，经测试后不是一定需要。至于百度账户的验证码有时需要有时不需要，下面代码中也有。
