Answer 4

是post登陆，但是不行。不知道是不是17k限制了什么？我已经试过不止6个方法  都不行！！！！！！！！！！

Answer 5

HttpClient 可以实现跨域(cookie的读写)  都能读写了，你还不能模拟登录么？
随便找个简单的例子你看吧 http://www.jb51.net/article/32255.htm

Answer 6

你没有把登录后返回的Cookies添加到cookieContainer: cookieContainer.Add(response.Cookies);
我测试可以获取登录后的个人中心页面。准备好充值了吗？using System;
