我做了一个功能的程序，它不工作时，请求类型是 GET ，如果是 POST ，它总是产生超时异常（和50年代的超时wasnt到达）的行 HttpWebResponse响应=（HttpWebResponse）request.GetResponse（）; 我试过很多东西，但我犯规找到了原因，也许这里有人知道这一点。 修改：得到它的工作，如果有人有兴趣： gist.github/4347248 任何帮助将大大AP preciated。 我的code是：
公共ResRequest请求（字符串URL，请求类型（典型值），CookieCollection饼干，串POSTDATA =，INT超时= 50000） { byte []的数据; 流REQ; 流RESP; HttpWebRequest的要求= WebRequest.Create（URL）为HttpWebRequest的; request.Timeout =超时; request.ContinueTimeout =超时; request.ReadWriteTimeout =超时; request.Proxy =新WebProxy（127.0.0.1，8118）; request.Headers.Add（Htt的prequestHeader.AcceptLanguage，德）; request.Headers.Add（UA-CPU，86）; request.Headers.Add（Htt的prequestHeader.AcceptEncoding，GZIP，放气）; request.UserAgent =Mozilla的/ 4.0（兼容; MSIE 7.0; Windows NT的6.0; WOW64; SLCC1; .NET CLR 2.0.50727; Media Center PC的5.0; .NET CLR 3.5.21022; .NET CLR 3.5.30729; .NET CLR 3.0.30618）; request.CookieContainer =新的CookieContainer（）; request.CookieContainer.Add（饼干）; 如果（典型值== RequestType.POST） { 数据= System.Text.Encoding.Default.GetBytes（POSTDATA）; request.Method =POST; request.ContentType =应用/的X WWW的形式urlen codeD; request.ContentLength = data.Length; REQ = request.GetRequestStream（）; //试了几次后，这产生了超时错误 req.Write（数据，0，data.Length）; req.Close（）; HttpWebResponse响应=（HttpWebResponse）request.GetResponse（）; //这一行产生超时异常 RESP = response.GetResponseStream（）; 如果（（response.ContentEncoding.ToLower（）。包含（GZIP））） { RESP =新System.IO.Com pression.GZipStream（RESP，System.IO.Com pression.Com pressionMode.Decom preSS）; }否则，如果（（response.ContentEncoding.ToLower（）。包含（放气）））{ RESP =新System.IO.Com pression.DeflateStream（RESP，System.IO.Com pression.Com pressionMode.Decom preSS）; } 返回新ResRequest（）{结果=新就是System.IO.StreamReader（RESP，System.Text.Encoding.UTF8）.ReadToEnd（），饼干= response.Cookies，CString的= cookiestring（response.Cookies）}; } 其他 { request.Method =GET; HttpWebResponse响应=（HttpWebResponse）request.GetResponse（）; RESP = response.GetResponseStream（）; 如果（（response.ContentEncoding.ToLower（）。包含（GZIP））） { RESP =新System.IO.Com pression.GZipStream（RESP，System.IO.Com pression.Com pressionMode.Decom preSS）; } 否则，如果（（response.ContentEncoding.ToLower（）。包含（放气））） { RESP =新System.IO.Com pression.DeflateStream（RESP，System.IO.Com pression.Com pressionMode.Decom preSS）; } 返回新ResRequest（）{结果=新就是System.IO.StreamReader（RESP，System.Text.Encoding.UTF8）.ReadToEnd（），饼干= response.Cookies，CString的= cookiestring（response.Cookies）}; } }解决方案
所以它每次都挂在 req.GetRequestStream（），或它的工作原理几试图然后挂机？
如果它工作了几下，然后挂起，它可能是你没有关闭请求不当，这是造成你用完的连接。确保关闭（）和/或的Dispose（）的 HttpWebResponse 的对象，所有的流和读者，你创造的。
I made a Function for a program, which does work when the Request Type is GET, if it is POST, it always produces a Timeout Exception(and the timeout of 50s wasnt reached) on the Line HttpWebResponse response = (HttpWebResponse)request.GetResponse(); I tried many things, but I doesnt found out why, may someone here know it. Edit: Got it to work, if someone is interested: gist.github/4347248 Any help will be greatly appreciated. My Code is:
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) }; } }解决方案
So does it hang on req.GetRequestStream() every time, or does it work "a few tries" and then hang?
If it works a few times and then hangs, it's possible that you're not closing the requests properly, which is causing you to run out of connections. Make sure to Close() and/or Dispose() the HttpWebResponse objects and all of the Streams and Readers that you're creating.
