HttpWebOperation 超时。为什么以及要检查什么？

我像这样调用 Web 服务（我的 Web 服务）：

var request = WebRequest.Create(Options.ServerUri + Options.AccountId + "/integration/trip") as HttpWebRequest;
request.Timeout = 20000; // 20 seconds should be plenty, no need for 100 seconds
request.ContentType = "application/json";
request.Headers.Add(HttpRequestHeader.Authorization, "Basic " + Convert.ToBase64String(Encoding.UTF8.GetBytes(Options.LoginName + ":" + Options.Password)));
request.Method = "POST";

var serializedData = (new JavaScriptSerializer()).Serialize(trip);

var bytes = Encoding.UTF8.GetBytes(serializedData);

request.ContentLength = bytes.Length;
var os = request.GetRequestStream();
os.Write(bytes, 0, bytes.Length);
os.Close();

request.GetResponse();

LoggingAndNotifications.LogAndNotify(string.Format("Success uploading trip: {0}", trip.TripId), false);

return true;

此代码重复调用以发布新对象。大约 3 次调用后，我开始在 reguest.GetReponse() 上超时

。服务器端没有错误，事件日志中没有任何错误。感觉就像“有什么东西”阻止我反复点击服务。我应该寻找什么？公司防火墙可以吗？还是我的代码有问题？

I'm calling web service (my web service) like this:

var request = WebRequest.Create(Options.ServerUri + Options.AccountId + "/integration/trip") as HttpWebRequest;
request.Timeout = 20000; // 20 seconds should be plenty, no need for 100 seconds
request.ContentType = "application/json";
request.Headers.Add(HttpRequestHeader.Authorization, "Basic " + Convert.ToBase64String(Encoding.UTF8.GetBytes(Options.LoginName + ":" + Options.Password)));
request.Method = "POST";

var serializedData = (new JavaScriptSerializer()).Serialize(trip);

var bytes = Encoding.UTF8.GetBytes(serializedData);

request.ContentLength = bytes.Length;
var os = request.GetRequestStream();
os.Write(bytes, 0, bytes.Length);
os.Close();

request.GetResponse();

LoggingAndNotifications.LogAndNotify(string.Format("Success uploading trip: {0}", trip.TripId), false);

return true;

This code called repeatedly to post new objects. After about 3 calls I start getting timeouts on reguest.GetReponse()

There is no errors on server side, nothing in Event Log. It feels like "something" stops me from repeatedly hitting service. What should I look for? Is it possible with company firewall? Or something wrong with my code?

我认为问题在于您没有关闭回复。尝试按如下方式编辑您的代码：

var response = request.GetResponse() as HttpWebResponse;
response.Close();

I think the issue is that you are not closing the response. Try editing your code as follows:

var response = request.GetResponse() as HttpWebResponse;
response.Close();

您应该按照

WebRequest myRequest = WebRequest.Create("http://www.contoso.com");

// Return the response. 
WebResponse myResponse = myRequest.GetResponse();

// Code to use the WebResponse goes here.

// Close the response to free resources.
myResponse.Close();

唔。 doco还说

此类型的任何公共静态（在 Visual Basic 中共享）成员都是
线程安全。不保证任何实例成员都是线程
安全。

您可能应该要求某种锁。

You should close the response as per the example in the doco.

WebRequest myRequest = WebRequest.Create("http://www.contoso.com");

// Return the response. 
WebResponse myResponse = myRequest.GetResponse();

// Code to use the WebResponse goes here.

// Close the response to free resources.
myResponse.Close();

Hmm. The doco also says
