发送方和接收方SOAP请求之间的合同不匹配

Question

我在使用.NET C＃发布SOAP请求时遇到问题，错误消息是->由于EndpointDispatcher上的ContractFilter不匹配，因此无法在接收方处理带有操作''的消息。这可能是由于合同不匹配（发送方和接收方之间的操作不匹配）或发送方和接收方之间的绑定/安全不匹配造成的。检查发送方和接收方具有相同的合同和绑定（包括安全性要求，例如消息，传输，无）。

 XmlDocument doc = new XmlDocument();
        string xmlDoc = ReadXML(@"..\..\PayLoad.xml");
        doc.LoadXml(xmlDoc);

        //Create web request
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create("https://teslaperf.sandbox.operations.dynamics.com/soap/services/TSLAJournalUploadConcurGroup");           
        req.Headers.Add("Authorization", OAuthHelper.GetAuthenticationHeader(true));
        req.ContentType = "text/xml;charset=\"utf-8\"";
        req.Accept = "text/xml";
        req.Method = "POST";

        //
        using (Stream stream = req.GetRequestStream())
        {
            doc.Save(stream);
        }

        try
        {
            using (WebResponse response = req.GetResponse())
            {
                using (StreamReader rd = new StreamReader(response.GetResponseStream()))
                {
                    string soapResult = rd.ReadToEnd();
                    Console.WriteLine(soapResult);
                }
            }
        }
        catch (WebException e)
        {
            if (e.Status == WebExceptionStatus.ProtocolError)
            {
                WebResponse resp = e.Response;
                using (StreamReader sr = new StreamReader(resp.GetResponseStream()))
                {
                    Console.WriteLine(sr.ReadToEnd());
                }
            }
        }
