发布到XML肥皂服务并且很难获得服务器响应

Question

当代码到达使用(WebResponse webResponse = webRequest.EndGetResponse(asyncResult))的行时，代码将引发500个html错误响应。

using System.Linq; 
using System.Net; 
using System.Text;

     // begin async call to web request. 
     IAsyncResult asyncResult = webRequest.BeginGetResponse(null, null); 

     // suspend this thread until call is complete. You might want to 
     // do something usefull here like update your UI. 
     asyncResult.AsyncWaitHandle.WaitOne(); 

     // get the response from the completed web request. 
     string soapResult; 
     using (WebResponse webResponse = webRequest.EndGetResponse(asyncResult)) 
     using (StreamReader rd = new StreamReader(webResponse.GetResponseStream())) 
     { 
      soapResult = rd.ReadToEnd(); 
     } 
     File.WriteAllText(_outputPath, (soapResult)); 
    } 

    private static void InsertSoapEnvelopeIntoWebRequest(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest) 
    { 
     using (Stream stream = webRequest.GetRequestStream()) 
     { 
      soapEnvelopeXml.Save(stream); 
     } 
    } 

} 

所有我需要做的就是服务响应，这样我可以能够使用

你的SOAP动作似乎是错误的方法。如果你看一下这里的架构（https://iserv.intecon.co.za/allpsws_test/allps.asmx?op=Call），你可以看到它的希望

SOAPAction: "http://intecon.co.za/webservices/allps/Call" 

与小提琴手（或类似的东西），一出戏，并尝试以确保您能获得通话的代码外工作。

使用此头：

Host: iserv.intecon.co.za 
Content-Type: text/xml; charset=utf-8 
SOAPAction: "http://intecon.co.za/webservices/allps/Call" 
Content-Length: 364 

而本机构：

<?xml version="1.0" encoding="utf-8"?> 
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> 
    <soap:Body> 
    <Call xmlns="http://intecon.co.za/webservices/allps/"> 
     <xmlrequest></xmlrequest> 
    </Call> 
    </soap:Body> 
</soap:Envelope> 

我得到一个200 OK响应 - 尽管它看起来像有一个与我打电话系统的问题，可能是因为我不知道我应该传递的XMLRequest应该是什么样子。

编辑：一起抛出一些代码为例：

static void Main(string[] args) 
{ 
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://iserv.intecon.co.za/allpsws_test/allps.asmx"); 

    request.Headers.Add("SOAPAction", "http://intecon.co.za/webservices/allps/Call"); 
    request.ContentType = "text/xml; charset=utf-8"; 
    request.Accept = "text/xml"; 
    request.Method = "POST"; 

    XmlDocument soapRequest = CreateEnvelope(); 

    using (Stream stream = request.GetRequestStream()) 
    { 
     soapRequest.Save(stream); 
    } 

    HttpWebResponse webResponse = (HttpWebResponse)request.GetResponse(); 

    StreamReader reader = new StreamReader(webResponse.GetResponseStream()); 

    string response = reader.ReadToEnd(); 

    Console.WriteLine(response); 
} 

private static XmlDocument CreateEnvelope() 
{ 
    var xmlDocument = new XmlDocument(); 

    xmlDocument.LoadXml(@"<?xml version=""1.0"" encoding=""utf-8""?> 
         <soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/""> 
          <soap:Body> 
          <Call xmlns=""http://intecon.co.za/webservices/allps/""> 
           <xmlrequest></xmlrequest> 
          </Call> 
          </soap:Body> 
         </soap:Envelope>"); 

    return xmlDocument; 
}
