httphelper登陆3g.ganji出现的问题。。。苏飞大大帮忙看看。。

fsdsdffdsa

一直result.html显示 本次请求并未返回任何数据 ，在 苏飞大大你的开发助手1.0带上 所有参数也是一样，我就考虑到是不是使用cookiecontain,还有就是http 1.1的问题。。。结果都不行。。。。

源码附上吧。。。用户名密码已经带上。。。

站长苏飞

看看是不是跳转了，看看header

fsdsdffdsa

多谢苏飞大大，果然是跳转了页面，之前的代码正确的。。。我这里有个疑问。。。 加上 Allowautoredirect = true  登陆就失败了。。。可是我用winhttp做  http.set_Option(WinHttpRequestOption.WinHttpRequestOption_EnableRedirects, true); 加上没有问题。。。登陆页正确

这个是我httphepler用的不对。。。还是理解的有问题。。。
