当我在HttpwebRequest c#中添加Host时，代理不工作

本文关键字：代理 工作 Host 添加 HttpwebRequest | 更新日期: 2023-09-27 18:01:01

我正试图使用HttpWebRequest Post登录到一个网站。它非常好用。但当我使用代理登录时，它就不起作用了。连接超时，如果我删除部分：

request.Host="abc.com"；

它再次与代理工作良好，但这样做将禁止我登录，因为网站需要这些信息。我怎么能克服这个问题？有什么建议吗？

                HttpWebRequest httpWReq =
               (HttpWebRequest)WebRequest.Create(url);
                ASCIIEncoding encoding = new ASCIIEncoding();
                string postData = post;
                byte[] data = encoding.GetBytes(postData);
                string proxy = "58.20.127.26:3128";
               /////byte[] data = GetBytes(postData);
                WebProxy myProxy = new WebProxy(proxy);
                httpWReq.Proxy = myProxy;
                httpWReq.Method = "POST";
                httpWReq.Accept = "text/html, application/xhtml+xml, */*";
                httpWReq.Referer = refferr;
                httpWReq.CookieContainer = yumCookies;
                httpWReq.ContentType = "application/x-www-form-urlencoded";
                httpWReq.UserAgent = "xxxxxxxxxxx";
                httpWReq.Host = "xxx.com";
                httpWReq.Headers.Add("Accept-Language: en-US");
                httpWReq.ContentLength = data.Length;
                httpWReq.KeepAlive = true;
                httpWReq.Headers.Add("Pragma: no-cache");
                httpWReq.AllowAutoRedirect = true;
                httpWReq.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
                using (Stream stream = httpWReq.GetRequestStream())
                {
                    stream.Write(data, 0, data.Length);
                }
                HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();
                if (response.StatusCode == HttpStatusCode.OK)
                {
                    Stream responseStream = response.GetResponseStream();
                    StreamReader myStreamReader = new StreamReader(responseStream);
                    responseString = myStreamReader.ReadToEnd();
                    if (response.Cookies.Count > 0)
                    {
                        foreach (Cookie ck in response.Cookies)
                        {
                            yumCookies.Add(ck);
                        }
                    }
                }
                response.Close();
                response = null;
                response = null;

当我在HttpwebRequest c#中添加Host时，代理不工作

您能分享更多的细节吗，比如如何创建请求、设置代理等？通常情况下，您不必像那样明确地设置主机。

这是我拥有的一份代码副本，它可以与代理完美配合：

                    var req = WebRequest.Create("http://google.com") as HttpWebRequest;
                    req.Proxy = new WebProxy("proxy-ip", 8080); //proxy ip/port
                    req.ContentType = "text/html";
                    req.Method = "GET";
