Question

请帮帮我。发送帖子查询后，我有一个感觉“错误获得响应流（ReadDone2）：接收失败”。帮助摆脱这个错误。感谢。

一段代码

try
{
string queryContent = string.Format("login={0}&password={1}&mobileDeviceType={2}/",
login, sessionPassword, deviceType);
request = ConnectionHelper.GetHttpWebRequest(loginPageAddress, queryContent);

using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())//after this line //occurs exception - "Error getting response stream (ReadDone2): Receive Failure"
{

ConnectionHelper.ParseSessionsIdFromCookie(response);

string location = response.Headers["Location"];
if (!string.IsNullOrEmpty(location))
{
string responseUri = Utils.GetUriWithoutQuery(response.ResponseUri.ToString());
string locationUri = Utils.CombineUri(responseUri, location);
result = this.DownloadXml(locationUri);
}
response.Close();
}
}
catch (Exception e)
{
errorCout++;
errorText = e.Message;
}

// Methot GetHttpWebRequest

    public static HttpWebRequest GetHttpWebRequest(string uri, string queryContent)
    {
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);            
        request.Proxy = new WebProxy(uri);
        request.UserAgent = Consts.userAgent;
        request.AutomaticDecompression = DecompressionMethods.GZip;
        request.AllowWriteStreamBuffering = true;
        request.AllowAutoRedirect = false;

        string sessionsId = GetSessionsIdForCookie(uri);
        if (!string.IsNullOrEmpty(sessionsId))
            request.Headers.Add(Consts.headerCookieName, sessionsId);

        if (queryContent != string.Empty)
        {
            request.ContentType = "application/x-www-form-urlencoded";
            request.Method = "POST";
            byte[] SomeBytes = Encoding.UTF8.GetBytes(queryContent);
            request.ContentLength = SomeBytes.Length;
            using (Stream newStream = request.GetRequestStream())
            {
                newStream.Write(SomeBytes, 0, SomeBytes.Length);
            }
        }
        else
        {
            request.Method = "GET";
        }

        return request;
    }

Answer 1

在我的情况下，服务器没有发送响应正文。修复服务器后，“接收失败”消失了。

所以你有两个选择：

如果没有响应流，请不要请求响应流。

确保服务器发送响应正文。

，而不是

self.send_response(200)
self.wfile.close()

Python服务器代码应该是

self.send_response(200)
self.send_header('Content-type', 'text/plain')
self.end_headers()
self.wfile.write("Thanks!\n")
self.wfile.close()

Answer 2

using (Stream newStream = request.GetRequestStream())
{
    newStream.Write(SomeBytes, 0, SomeBytes.Length);

    //try to add
    newStream.Close();
}

其非 Xamarin或.NET的错误。：wink：

您的服务器端端点在请求时失败。：中立：

检查您的API端点（如果您拥有api），或者如果您从第三方公司或服务获取API，请与支持人员联系。

为什么随机发生：：wink：因为错误在您的内部if或loop块中，并且会在通过该错误循环或if时发生。

最好的问候。：微笑：
