获取响应流时出错(ReadDone1):ReceiveFailure

Question

我正在使用Xamarin开发一个Android应用程序,在将Xamarin升级到它的最新版本之后,我的WebRequest中抛出了以下异常:

{System.Net.WebException:获取响应流时出错(ReadDone1):ReceiveFailure ---> System.IO.IOException:EndRead failure ---> System.Net.Sockets.SocketException:System.Net.Sockets上的peer重置连接.Socket.EndReceive(IAsyncResult结果)[0x00000] in:0在System.Net.Sockets.NetworkStream.EndRead(IAsyncResult ar)[0x00000] in:0 ---内部异常堆栈跟踪结束---在System.Net .Sockets.NetworkStream.EndRead(IAsyncResult ar)[0x00000] in:0 at Mono.Security.Protocol.Tls.SslStreamBase.InternalReadCallback(IAsyncResult result)[0x00000] in:0 ---内部异常堆栈跟踪结束---在System.Net.HttpWebRequest.EndGetResponse(IAsyncResult asyncResult)[0x00000] in:0 in System.Threading.Tasks.TaskFactory1 [System.Net.WebResponse] .InnerInvoke(System.Threading.Tasks.TaskCompletionSource1 tcs,System.Func)

这是代码:

try
{
    ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);

    string data = "access_token=" + System.Web.HttpUtility.UrlEncode(accessToken) + "&refresh_token=" + System.Web.HttpUtility.UrlEncode(refreshToken);

    WebRequest myWebRequest = (HttpWebRequest)WebRequest.Create(url + "?" + data);

    myWebRequest.Method = method;
    myWebRequest.ContentLength = data.Length;
    myWebRequest.ContentType = "application/x-www-form-urlencoded";
    HttpWebResponse response = await myWebRequest.GetResponseAsync() as HttpWebResponse;

    string headerSetCookie = response.Headers["Set-Cookie"];
    response.Close();
    return headerSetCookie;    
}
catch (Exception e)
{
    throw e;
}

有什么想法它会引发异常吗？还在Xamarin论坛上发布了这个问题:https://forums.xamarin.com/discussion/32554/error-getting-response-stream-readdone1-receivefailure？new = 1

谢谢你的问候.
