Question

我有一个方法，我用来登录网站。每次，此方法都会创建一个新的Webrequest和Webresponse，它在前两次工作正常。但是，我第三次调用它时，它会挂起（在using (Stream stream = request.GetRequestStream())行）。我不知道为什么。我正在处理一切。这是我的方法：

public static void Login()
{
    //Create HTTP request
    HttpWebRequest request =
        WebRequest.CreateHttp("https://www.mcgamerzone.com/login?username=username&url=/settings/security");

    //Set request headers
    request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
    request.KeepAlive = true;
    request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0";
    request.Method = "POST";
    request.Headers = new WebHeaderCollection {
        {"Accept-Language", "en-US,en;q=0.5"}
    };

    //Post data
    Dictionary<string, string> postDict = new Dictionary<string, string> {
        {"login", "Login"},
        {"password", "password"},
        {"username", "username"}
    };

    //Post data as byte array
    byte[] postData = new FormUrlEncodedContent(postDict).ReadAsByteArrayAsync().Result;
    request.ContentLength = postData.Length;
    request.ContentType = "application/x-www-form-urlencoded";

    //Write post data to request stream
    using (Stream stream = request.GetRequestStream())
        stream.Write(postData, 0, postData.Length);
}

然后在控制台应用程序中使用它：

static void Main(string[] args)
{
    Login();
    Console.WriteLine("Logged in");

    Login();
    Console.WriteLine("Logged in");

    Login();
    Console.WriteLine("Logged in");
}

＆＃34;登录＆＃34;在控制台中出现2次。第三个出现大约需要3分钟我无法弄清楚它悬挂的原因。当然，这不是因为我没有正确处理对象，因为我每次都在创建一个新对象。 Wireshark表明它没有向服务器发送信息，服务器也没有发送信息。

HttpWebRequest挂在第三个电话上
