处理非WCF客户端的WCF故障

我创建了一个Wcf服务。它将由Wcf客户端和非Wcf客户端访问。我为FaultException处理创建了自己的类,如下所示;

[DataContract]
public class ErrorResponse
{
    [DataMember]
    public string ErrMsg {get;set;}
}

对于我的服务界面,我有

[ServiceContract]
public interface IService
{
    [OperationContract]
    [FaultContract (typeof(ErrorResponse))]
    [WebInvoke(Method = "POST", UriTemplate = "/XML/GetTypes", BodyStyle = WebMessageBodyStyle.Bare)]
    TypeResponse XMLTypes(TypeRequest TypeRequest);
}

在我的方法XmlTypes中,我有以下内容;

public static TypeResponse XmlTypes(TypeRequest TypeRequest)
{
    //do something
    //raise a error

    ErrorResponse oErrorResponse = new ErrorResponse();
    oErrorResponse.ErrMsg = "Some Error happened";

    FaultCode oFaultCode = new FaultCode("12345");

    throw new FaultException<ErrorResponse>(oErrorResponse , new FaultReason ("Reason for the fault"),
            new FaultCode("TypeRequestFailed", new FaultCode("TypeNotFound")));

这似乎适用于Wcf客户端。

然而,当从非Wcf客户端进行调用时,例如使用WebClient UploadString(我知道我可以使用服务引用,这是出于测试目的),我回来了

  

System.Net.WebException:远程服务器返回错误:(400)   不良请求。

这是我在另一个测试应用中的webclient代码;

WebClient oClient = new WebClient();

oClient.Encoding = UTF8Encoding.UTF8;
oClient.Headers.Add("Content-Type", "application/xml");

try 
{
   txtResponse.Clear();

   sRequest = "<TypeRequest><UserId>1</UserId><Password>asdax12</Password></TypeRequest>";
   txtResponse.Text = oClient.UploadString("http://localhost:49562/Service.svc/XML/XmlTypes", "POST", sRequest).ToString();
}
catch (Exception ex)
{
    txtResponse.Text = ex.ToString();
}

在我的webconfig文件中,我添加了以下示例throwing soap faults for non wcf clients

<system.serviceModel>
  <bindings>
    <customBinding>
      <binding name="basicHttpSoap12Binding">
        <textMessageEncoding messageVersion="Soap12"/>
        <httpTransport/>
      </binding>
    </customBinding>
  </bindings>
  <services>
    <service name="MySoap12Service">
      <endpoint address="" binding="customBinding" bindingConfiguration="basicHttpSoap12Binding"
        bindingNamespace="MySoap12ServiceNamespace"
        contract="MySoap12Service">
      </endpoint>
    </service>
  </services>
</system.serviceModel>

我哪里错了?

答案 0 :(得分:1)

您是否有其他可以称为成功的网络方法? (来自同一个非WCF客户端)

由于你有一个400 http的错误,在我看来,呼叫没有以正确的方式构建或完成,所以如果你能成功调用同一服务中的任何其他方法,这将有助于我们确保呼叫是正确的。
