获取响应流时出错（ReadDone2）：接收失败

请帮助我。发送帖子后，我有webexception“获取响应流（ReadDone2）：接收失败”错误。帮助摆脱这个错误。谢谢。获取响应流时出错（ReadDone2）：接收失败

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; 
    }

你能后的ConnectionHelper类的代码（或者只是在GetHttpWebRequest方法）？ – clarkb86

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

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

当使用'using'关键字时，是否有必要显式调用Close（）函数？我认为这个流在超出'使用'声明的范围时会自动处理/关闭。 –

我也这么认为，但在实践中没有.Close（）它不会发送请求。 – mironych

在我的情况下，服务器没有响应体。修复服务器后，“接收失败”消失。

所以，你有两个选择：

不要请求响应流，如果你能活着离不开它。

确保服务器发送响应正文。

例如，而不是

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

Python的服务器代码应该是

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