[c＃应用程序在没有提琴手的情况下不会发送请求

Question

我已将此应用程序编码为c＃。该应用程序使用httpclient和webrequests方法。

我面临的问题是，当我运行应用程序时，它实际上并未发送请求。但是，当我运行提琴手然后运行应用程序时，它会发送请求并且可以正常运行。可能是什么原因？

此发送请求。

public void Login()
        {

            Loginfirst();

            //Create cookies

            // create request
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www." + server_site + ".com/login");
            //request.CookieContainer = cookieJar;

            request.Method = "POST";
            string postData = "email=" + Username + "&password=" + Password + "&remember=false&request_type=ajax";
            byte[] byteArray = Encoding.UTF8.GetBytes(postData);


            //set the contenttype property
            request.ContentType = "application/x-www-form-urlencoded";
            request.ServicePoint.Expect100Continue = true;
            //request.AllowAutoRedirect = true;
            //set header
            request.UserAgent = User_Agent;
            request.Accept = "application/json";
            request.Headers.Add("X-Requested-with", "XMLHttpRequest");


            request.Headers.Add("Cookie", m_cookies);

            log_file("line 975" + m_cookies);


            //request.Headers["Cookie"] = "rlogin=" + Username + "";
            request.KeepAlive = false;
            //set the contentlength property of the WebRequest
            request.ContentLength = byteArray.Length;

            // get the stream containing returned by the server.
            Stream dataStream = request.GetRequestStream();
            // Write the data to the request stream
            dataStream.Write(byteArray, 0, byteArray.Length);
            //close the Stream object
            dataStream.Close();
            // get the response

                }

                dataStream = response.GetResponseStream();
                //open the stream using a streamreader for easy access.
                StreamReader reader = new StreamReader(dataStream);

                    Login();
                    return;

t0 = new Task(bb0.Login);
                t0.Start();

    t1 = new Task(bb1.Login);
                t1.Start();
    t2 = new Task(bb2.Login);
                t2.Start();

任务t0在没有提琴手的情况下工作。没有提琴手，任务t1将无法工作。没有提琴手，任务t2将无法工作。

您一次只能成功完成一项任务。就像您运行t2一样，则无法使用t1，反之亦然。

这只会创建请求对象。您必须调用GetResponse()或BeginGetResponse()才能将请求实际发送到服务器。
