在C＃控制台应用程序中发送SOAP请求时发生错误

Question

我想在C＃控制台应用程序中发布请求，并且出现此错误。该请求在SOAPUI中工作，没有WSDL文件，因此我必须直接在代码中加载XML（我高度怀疑这是错误的来源）。

上的控制台应用程序的输出如下：

的SOAPUI请求工作如下：

这里是我使用的这个SOAP请求传送的C＃控制台应用程序。

using System.Threading.Tasks; 
using System.Xml; 

namespace IMSPostpaidtoPrepaid 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      Program obj = new Program(); 
      obj.createSOAPWebRequest(); 
     } 

     //Create the method that returns the HttpWebRequest 
     public void createSOAPWebRequest() 
     { 

      //Making the Web Request 
      HttpWebRequest Req = (HttpWebRequest)WebRequest.Create(@"http://127.1.1.0:9090/spg"); 

      //Content Type 
      Req.ContentType = "text/xml;charset=utf-8"; 
      Req.Accept = "text/xml"; 

      //HTTP Method 
      Req.Method = "POST"; 

      //SOAP Action 
      Req.Headers.Add("SOAPAction", "\"SOAPAction:urn#LstSbr\""); 

      NetworkCredential creds = new NetworkCredential("username", "pass"); 
      Req.Credentials = creds; 

      Req.Headers.Add("MessageID", "1"); //Adding the MessageID in the header 

      string DN = "+26342720450"; 
      string DOMAIN = "ims.telone.co.zw"; 

      //Build the XML 
      string xmlRequest = String.Concat(
       "<?xml version=\"1.0\" encoding=\"utf-8\"?>", 
       "<soap:Envelope", 
       "  xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\"", 
       "  xmlns:m=\"http://www.huawei.com/SPG\"", 
       "  xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"", 
       "  xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">", 
       " <soap:Body>", 
       "<m:LstSbr xmlns=\"urn#LstSbr\">", 
       " <m:DN>", DN, "</ m:DN>", 
       " <m:DOMAIN>", DOMAIN, "</ m:DOMAIN>", 
       " </m:LstSbr>", 
       " </soap:Body>", 
       "</soap:Envelope>"); 


      //Pull Request into UTF-8 Byte Array 
      byte[] reqBytes = new UTF8Encoding().GetBytes(xmlRequest); 

      //Set the content length 
      Req.ContentLength = reqBytes.Length; 

      //Write the XML to Request Stream 
      try 
      { 
       using (Stream reqStream = Req.GetRequestStream()) 
       { 
        reqStream.Write(reqBytes, 0, reqBytes.Length); 
       } 
      } 
      catch (Exception ex) 
      { 
       Console.WriteLine("Exception of type " + ex.GetType().Name + " " + ex.Message); 
       Console.ReadLine(); 
       throw; 
      } 

      //Headers and Content are set, lets call the service 
      HttpWebResponse resp = (HttpWebResponse)Req.GetResponse(); 

      string xmlResponse = null; 

      using (StreamReader sr = new StreamReader(resp.GetResponseStream())) 
      { 
       xmlResponse = sr.ReadToEnd(); 
      } 
      Console.WriteLine(xmlResponse); 
      Console.ReadLine(); 

     } 

    } 
}

这是我用来发布到Web服务的基本方法。

static XNamespace soapNs = "http://schemas.xmlsoap.org/soap/envelope/"; 
static XNamespace topNs = "Company.WebService"; 

private System.Net.HttpWebResponse ExecutePost(string webserviceUrl, string soapAction, string postData) { 
    var webReq = (HttpWebRequest)WebRequest.Create(webserviceUrl); 
    webReq.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip; 
    webReq.ContentType = "text/xml;charset=UTF-8"; 
    webReq.UserAgent = "Opera/12.02 (Android 4.1; Linux; Opera Mobi/ADR-1111101157; U; en-US) Presto/2.9.201 Version/12.02"; 
    webReq.Referer = "http://www.company.com"; 
    webReq.Headers.Add("SOAPAction", soapAction); 
    webReq.Method = "POST"; 

    var encoded = Encoding.UTF8.GetBytes(postData); 
    webReq.ContentLength = encoded.Length; 
    var dataStream = webReq.GetRequestStream(); 
    dataStream.Write(encoded, 0, encoded.Length); 
    dataStream.Close(); 

    System.Net.WebResponse response; 
    try { response = webReq.GetResponse(); } 
    catch { 
     ("Unable to post:\n" + postData).Dump(); 
     throw; 
    } 

    return response as System.Net.HttpWebResponse; 
} 

然后，我可以建立任何我想要做的事情来做我所需要的。例如，这里是我将如何使用它。

private void CreateTransaction(string webServiceUrl, string ticket, double costPerUnit) { 
    string soapAction = "Company.WebService/ICompanyWebService/CreatePurchaseTransaction"; 
    var soapEnvelope = new XElement(soapNs + "Envelope", 
         new XAttribute(XNamespace.Xmlns + "soapenv", "http://schemas.xmlsoap.org/soap/envelope/"), 
         new XAttribute(XNamespace.Xmlns + "top", "Company.WebService"),      
        new XElement(soapNs + "Body", 
         new XElement(topNs + "CreatePurchaseTransaction", 
          new XElement(topNs + "command", 
           new XElement(topNs + "BillTransaction", "true"), 
           new XElement(topNs + "BillingComments", "Created By C# Code"), 
           new XElement(topNs + "Department", "Development"), 
           new XElement(topNs + "LineItems", GetManualPurchaseLineItems(topNs, costPerUnit)),         
           new XElement(topNs + "Surcharge", "42.21"), 
           new XElement(topNs + "Tax", "true"), 
           new XElement(topNs + "TransactionDate", DateTime.Now.ToString("yyyy-MM-dd")) 
        )))); 

    var webResp = ExecutePost(webServiceUrl, soapAction, soapEnvelope.ToString()); 
    if (webResp.StatusCode != HttpStatusCode.OK) 
     throw new Exception("Unable To Create The Transaction"); 

    var sr = new StreamReader(webResp.GetResponseStream()); 
    var xDoc = XDocument.Parse(sr.ReadToEnd()); 
    var result = xDoc.Descendants(topNs + "ResultType").Single(); 
    if (result.Value.Equals("Success", StringComparison.CurrentCultureIgnoreCase) == false) 
     throw new Exception("Unable to post the purchase transaction. Look in the xDoc for more details."); 
} 

private IEnumerable<XElement> GetManualPurchaseLineItems(XNamespace topNs, double costPerUnit) { 
    var lineItems = new List<XElement>(); 

    lineItems.Add(new XElement(topNs + "PurchaseLineItem", 
         new XElement(topNs + "Count", "5"), 
         new XElement(topNs + "ExpenseClass", "Tech Time"), 
         new XElement(topNs + "ItemName", "Brushing and Flossing"), 
         new XElement(topNs + "Location", "Your House"), 
         new XElement(topNs + "UnitCost", costPerUnit.ToString("#.00")))); 

    return lineItems; 
} 

您需要将其调整为您的控制台应用程序，但这是否有助于您继续操作？
