三.关于验证码识别登录

####验证码识别

验证码图片url不变，验证码不变
- 　　请求验证码图片获得验证码图片，通过打码品台识别
验证码url不变，验证码会变
- 　　思路：对方服务器在返回烟验证码的时候，会和每个用户信息进行一个对应，之后再用户发起post请求的时候，会对比post请求的中的验证码和当前用户真正存储在服务器端的验证码是否相同　　
- 操作：
  - 实例化session
  - 使用session请求登录页面获得验证的地址
  - 使用session请求验证码，识别
  - 使用session发送post请求
使用selenniu登录，遇到验证码
- 　　url不变，验证码不变，同上
- 　　url不变，验证码会变
  - 使用selenium请求登录页面，同时拿到验证码地址
  - 获取登录页面中的cookie，就是实例化的浏览器中使用get——cookies，交给request模块去请求，识别
  - 输入验证码识别
