[ASP.net教程]【青椒原创】2016C#模拟谷歌Google登陆GmailYoutube小案例


之所以写这个,是因为本来想写一个Youtube刷评论的工具,把登录做出来了,后面就没继续做下去。

涉及到基本的HttpWatch的应用以及Fiddler的应用(Fd主要用来排查问题,通过对比 浏览器和vs代码 找出问题所在!以浏览器为标准)。

通过HttpWatch抓包分析,我把登录Youtube一共分为三个阶段:

1. 请求 打开录入邮箱地址 页面

2. 请求 回发本邮箱地址,加载邮箱账号 头像

3. 请求 回发本邮箱地址和密码, 登录Youtube

有很多的Cookie和PostData的话是 服务器不做校验的,也就是说重要的 Cookie和Post/Get数据并不是全部你所看到的,这个你可以后期 模拟登陆成功之后,逐个删掉测试看是否还能登陆成功 来判断 该参数是否必须!

上面的原理其实在做其他 网站的模拟 登录 中也是一样的。

大家直接看代码吧,没啥好讲的也。
