HttpWebRequest.GetResponse操作已超时

Question

我正在尝试从网站获取简单的gzip编码的html响应，并且该响应持续超时，以下是我的代码：

HttpWebRequest httpClient = (HttpWebRequest)WebRequest.Create(url);
httpClient.Method = "GET";
httpClient.Accept = "text/html, application/xhtml+xml, */*";
httpClient.Headers.Add("Accept-Encoding: gzip, deflate");
httpClient.Headers.Add("Accept-Language: en-US");
httpClient.Headers.Add("DNT: 1");
httpClient.ProtocolVersion = HttpVersion.Version10;
httpClient.KeepAlive = true;
httpClient.Timeout = System.Threading.Timeout.Infinite;
httpClient.CookieContainer = cookieJar;

String responseAsText;
using (HttpWebResponse response = (HttpWebResponse)httpClient.GetResponse())
{
     System.IO.StreamReader sr;
     if (response.ContentEncoding.Equals("gzip"))
     {
          sr = new StreamReader(new GZipStream(response.GetResponseStream(), CompressionMode.Decompress));
     }
     else
     {
           sr = new System.IO.StreamReader(response.GetResponseStream());
     }
     responseAsText = sr.ReadToEnd();
 }

我要输入的网址是“ https client.schwab.com/Login/SignOn/CustomerCenterLogin.aspx”

这在浏览器中工作得很好，使用Fiddler，我查看了浏览器的Request标头，并且由于它的Transfer-Encoding: chunked HttpVersion10 ，我使用了HttpVersion10

我也尝试过设置httpClient.Timeout = System.Threading.Timeout.Infinite ，但是它永远不会返回响应，但是在浏览器中响应会在几秒钟内得到。

请有人帮助我实现这一目标。

可能您可以尝试设置代理属性，这样它就不会将您识别为漫游器。

我认为Nero回答了您的问题..

尝试在代码中添加这些行。

request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0";
