request.GetResponse总是提供超时
我为一个程序创建了一个函数，它在请求类型为GET ，如果它是POST ，它总是在Line HttpWebResponse response = (HttpWebResponse)request.GetResponse();上产生一个Timeoutexception（并且没有达到50s的超时）。 HttpWebResponse response = (HttpWebResponse)request.GetResponse();
我尝试了很多东西，但我没有发现原因，也许有人在这里知道。

任何帮助将不胜感激。
我的代码是：
public ResRequest request(string URL, RequestType typ, CookieCollection cookies, string postdata ="", int timeout= 50000) { byte[] data; Stream req; Stream resp; HttpWebRequest request = WebRequest.Create(URL) as HttpWebRequest; request.Timeout = timeout; request.ContinueTimeout = timeout; request.ReadWriteTimeout = timeout; request.Proxy = new WebProxy("127.0.0.1", 8118); request.Headers.Add(HttpRequestHeader.AcceptLanguage, "de"); request.Headers.Add("UA-CPU", "x86"); request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip, deflate"); request.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; WOW64; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.21022; .NET CLR 3.5.30729; .NET CLR 3.0.30618) "; request.CookieContainer = new CookieContainer(); request.CookieContainer.Add(cookies); if (typ == RequestType.POST) { data = System.Text.Encoding.Default.GetBytes(postdata); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = data.Length; req = request.GetRequestStream();//after a few tries this produced a Timeout error req.Write(data, 0, data.Length); req.Close(); HttpWebResponse response = (HttpWebResponse)request.GetResponse();//This line produces a Timeout Exception resp = response.GetResponseStream(); if ((response.ContentEncoding.ToLower().Contains("gzip"))) { resp = new System.IO.Compression.GZipStream(resp, System.IO.Compression.CompressionMode.Decompress); } else if ((response.ContentEncoding.ToLower().Contains("deflate"))) { resp = new System.IO.Compression.DeflateStream(resp, System.IO.Compression.CompressionMode.Decompress); } return new ResRequest() { result = new System.IO.StreamReader(resp, System.Text.Encoding.UTF8).ReadToEnd(), cookies = response.Cookies, cstring = cookiestring(response.Cookies) }; } else { request.Method = "GET"; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); resp = response.GetResponseStream(); if ((response.ContentEncoding.ToLower().Contains("gzip"))) { resp = new System.IO.Compression.GZipStream(resp, System.IO.Compression.CompressionMode.Decompress); } else if ((response.ContentEncoding.ToLower().Contains("deflate"))) { resp = new System.IO.Compression.DeflateStream(resp, System.IO.Compression.CompressionMode.Decompress); } return new ResRequest() { result = new System.IO.StreamReader(resp, System.Text.Encoding.UTF8).ReadToEnd(), cookies = response.Cookies, cstring = cookiestring(response.Cookies) }; } }
那么它每次都挂在req.GetRequestStream() ，还是“几次尝试”然后挂起？
如果它工作了几次然后挂起，那么你可能没有正确关闭请求，这会导致你的连接用完。 确保Close()和/或Dispose() HttpWebResponse对象以及您正在创建的所有Streams和Readers。
你必须使用response.Dispose（）;
方法结束
