不能將HTTP頭添加到SOAP請求中

Question

我已經查看了將HTTP頭添加到SOAP請求的答案，並找到了一些好的並使用了代碼。我想我在附加的代碼中擁有一切，但是當我在Fiddler中查看請求時，看不到任何頭文件被添加。有人可以看看我在這裏是否缺少東西嗎？謝謝。這是一項PeopleSoft服務。

UTZ_EMP_BIO_INFO_PortTypeClient utz = new UTZ_EMP_BIO_INFO_PortTypeClient(); 
UTZ_EMP_BIO_INFO_PortType utShare = utz; 


using (System.ServiceModel.OperationContextScope scope = new System.ServiceModel.OperationContextScope((IContextChannel)utz.InnerChannel)) 
     { 
      MessageHeaders messageHeadersElement = System.ServiceModel.OperationContext.Current.OutgoingMessageHeaders; 
      messageHeadersElement.Add(MessageHeader.CreateHeader("SOAPAction", String.Empty, "UTZ_EMP_BIO_INFO.v1")); 

      Console.WriteLine("down under"); 
      SendEmpBioRespV1 resp = default(SendEmpBioRespV1); 
      rqst.GetEmpBioInfoReq.GetEmpBioInfo.UTZ_EMP_SRCH_VW.SSN = "123456789"; 
      rqst.GetEmpBioInfoReq.GetEmpBioInfo.UTZ_EMP_SRCH_VW.EMPLID = ""; 
      resp = utShare.UTZ_EMP_BIO_INFO(rqst); 
      Console.WriteLine(resp.SendEmpBioResp.SendEmpBioInfo.UTZ_EMP_BIO_WRK.CITY); 
     }

我會建議您使用HttpWebRequest類：

http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx

HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("http://www.contoso.com/");

然後就可以調用Headers.Add

myReq.Headers.Add("SOAPAction", "\"http://www.contoso.com/Action\"");

UPDATE ：一個例子：How to send/receive SOAP request and response using C#?

但

根據你的例子，我會使用類似：

using (System.ServiceModel.OperationContextScope scope = new System.ServiceModel.OperationContextScope((IContextChannel)utz.InnerChannel)) 
{ 
    MessageHeaders messageHeadersElement = MessageHeader.CreateHeader("SOAPAction", String.Empty, "UTZ_EMP_BIO_INFO.v1"); 

    OperationContext.Current.OutgoingMessageHeaders.Add(messageHeadersElement); 
etc...
