HttpHelper想自定义添加一个HTTP头结果报错，求解决

.zZ

我想做一个模拟登录到微信公众平台的程序，
通过抓包发现登录之后GET到主页的HTTP都不里面有一个：Host: mp.weixin.qq.com
我想在HttpItem里面的Header.Add("Host", "mp.weixin.qq.com")方法添加，结果报错。
如图

不能直接修改HOST应该怎么办？

我把代码也贴上

[C#] 纯文本查看 复制代码

HttpItem item = new HttpItem();
            item.URL = url;
            item.Encoding = Encoding.UTF8;
            item.Method = "GET";
            item.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; InfoPath.2; .NET CLR 2.0.50727; .NET4.0C; .NET4.0E; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)";
            item.Referer = "mp.weixin.qq.com/cgi-bin/login?lang=zh_CN";
            item.ContentType = "application/x-www-form-urlencoded; charset=UTF-8";
            item.Accept = "application/x-shockwave-flash, image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/xaml+xml, application/x-ms-xbap, application/x-ms-application, application/vnd.ms-xpsdocument, */*";
            item.Cookie = cookies;
            item.Header.Add("Host", "mp.weixin.qq.com");

站长苏飞

哈哈，host可以直接修改，有这个属性，不能加到header
