Question

当我尝试发送/接收大量请求/响应时，Web服务（asmx）出现问题...我一直收到错误“基础连接已关闭：接收时发生意外错误“

HttpWebRequest request = HttpWebRequest.Create("https://test.smth.cin:443/ws/1.0") as HttpWebRequest;
request.KeepAlive = true;
request.Method = "POST";
request.ContentType = "text/xml; charset=utf-8";
request.ClientCertificates.Add(Cert);
request.Headers.Add("SOAPAction", @"https://test.smth.cin:443/ws/1.0" + p_SOAPAction);
request.Timeout = 2200000;
StreamWriter requestWriter = new StreamWriter(request.GetRequestStream(),System.Text.Encoding.UTF8);
requestWriter.Write(str_SOAP);
requestWriter.Flush();
requestWriter.Close(); 



   HttpWebResponse response = request.GetResponse() as HttpWebResponse;
    Stream responsedata = response.GetResponseStream();
    StreamReader responsereader = new StreamReader(responsedata);

    WS_Response ws_r = new WS_Response();
    XmlDocument WS_XML_Response = new XmlDocument();

    byte[] encodedString = Encoding.UTF8.GetBytes(str_SOAP);

    // Put the byte array into a stream and rewind it to the beginning
    MemoryStream ms = new MemoryStream(encodedString);
    ms.Flush();
    ms.Position = 0;
    WS_XML_Response.Load(ms);

我还在webconfig中设置<httpRuntime maxRequestLength="200000" executionTimeout="360000" />，但我仍然收到错误。

有什么想法吗？

Answer 1

请更改u maxRequestLenght = Int32.MaxValue（）;

这将是某个地方 = 2147481263

Answer 2

当我在过去看到这个错误时，问题是响应XML无效并且由于在处理无效XML期间发生异常而关闭连接。我会尝试保存原始XML请求数据，然后根据Web服务的架构验证XML数据。你可能会发现响应XML中存在一些无效的东西导致连接被强制关闭。
