有谁知道为什么我收到的HttpWebRequest超时? [英] Does anyone know why I receive an HttpWebRequest Timeout?
问题描述
我在想,如果你能帮助我,我是个有一个错误。我有我创建了一个HTTP管理器,可以帮助我处理发布/从网站上歌厅的数据。它一直很好,直到最近,当我试图用两者的混合。第一循环轮一切正常,在第二圈就挂在HttpWebRequest.GetRequestStream()。我已阅读所有过网,并没有发现任何真正的解决方案。下面是为取/接收代码块:
I was wondering if you can help me with a bug I ma having. I have a HTTP Manager I have created that helps me dealing with POSTing/GETing data from websites. It has worked fine until recently when I am trying to use a mixture of both. First loop round everything works, on the second loop it hangs on HttpWebRequest.GetRequestStream(). I have read all over the net and have found no real solution. Below are the codeblocks for the fetching/receiving:
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] buffer = encoding.GetBytes(_PostData);
_HttpWebRequest = (HttpWebRequest)WebRequest.Create(_FetchUrl);
_HttpWebRequest.Credentials = _Credentials;
_HttpWebRequest.Method = _RequestType.ToString();
_HttpWebRequest.ContentType = "application/x-www-form-urlencoded";
_HttpWebRequest.ContentLength = buffer.Length;
_HttpWebRequest.UserAgent = userAgent;
_HttpWebRequest.CookieContainer = _CookieContainer;
_HttpWebRequest.KeepAlive = false;
_HttpWebRequest.AllowAutoRedirect = _AllowAutoRedirect;
_HttpWebRequest.AutomaticDecompression = DecompressionMethods.GZip;
_HttpWebRequest.ServicePoint.Expect100Continue = false;
if (_RequestType.Equals(RequestTypes.POST))
{
// Write POST
Stream reqStream = _HttpWebRequest.GetRequestStream();
{
reqStream.Write(buffer, 0, buffer.Length);
reqStream.Flush();
reqStream.Close();
}
}
和的的回复:
HttpWebResponse httpWebResponse = (HttpWebResponse)_HttpWebRequest.GetResponse();
{
Stream responseStream = httpWebResponse.GetResponseStream();
{
if (_UseGzip)
{
if (httpWebResponse.ContentEncoding.ToLower().Contains("gzip"))
{
responseStream = new GZipStream(responseStream, CompressionMode.Decompress);
}
else
{
responseStream = new DeflateStream(responseStream, CompressionMode.Decompress);
}
}
if (responseStream != null)
{
StreamReader streamReader = new StreamReader(responseStream);
{
try
{
_PageContent = streamReader.ReadToEnd();
}
finally
{
streamReader.Close();
responseStream.Close();
httpWebResponse.Close();
}
}
}
else
{
_PageContent = string.Empty;
}
}
}
_HttpWebRequest.Abort();
任何人都可以看到任何破绽,为什么我的代码是挂?所有的数据流都被关闭,我已经设置了允许连接到100,我不明白这是为什么打破。
Can anyone see any flaws to why my code is hanging? All streams are being closed, I have set the allowed connections to over 100, I don't understand why this is breaking.
推荐答案
这可能是由于这样的事实,你不处理你的WebResponse类或流或StreamReaders的:
This may be due to the fact that you are not disposing of your WebResponse or streams or StreamReaders:
var request = WebRequest.Create(...);
using (var response = request.GetResponse())
{
using (var responseStream = response.GetResponseStream())
{
using (var reader = new StreamReader(responseStream))
{
// use the reader
}
}
}
