将命名空间添加到 WCF 方法

Question

我有这个 WCF 项目，我想向方法添加 'tem' 前缀，而不是像这些行那样输入 XML 代码

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/"> 
<soapenv:Header/><soapenv:Body>
<tem:FetchServiceInfoByBillId>
<USER_NAME>username</USER_NAME>
</tem:FetchServiceInfoByBillId>
</soapenv:Body>
</soapenv:Envelope>

这是界面

[ServiceContract(Namespace ="")]
public interface IOnlineService
{
  [OperationContract]
  [return: MessageParameter(Name = "Error_code")]
  string FetchServiceInfoByBillId(string USER_NAMES);

}

我用这个界面得到了这些XML

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/"> 
<soapenv:Header/><soapenv:Body>
<FetchServiceInfoByBillId>
<USER_NAME>username</USER_NAME>
</FetchServiceInfoByBillId>
</soapenv:Body>
</soapenv:Envelope>

如果我使用 [ServiceContract] 而不是 [ServiceContract(Namespace ="")] 我会在方法和输入之前得到 'tem' 但我只想在方法名称之前得到它

您可以使用 MessageInterceptor 自定义或修改 SOAP 消息。

这是客户端的示例代码：

     public class ClientMessageLogger : IClientMessageInspector
{
    public void AfterReceiveReply(ref Message reply, object correlationState)
    {
        MessageHeader header1 = MessageHeader.CreateHeader("Testreply", "http://Test", "Test");
    request.Headers.Add(header1);
    }

    public object BeforeSendRequest(ref Message request, IClientChannel channel)
    {
        MessageHeader header = MessageHeader.CreateHeader("UserAgent", "http://User", "User1");
    reply.Headers.Add(header);
    return null;

    }
}
[AttributeUsage(AttributeTargets.Interface)]
public class CustomBehavior : Attribute, IContractBehavior
{
    public Type TargetContract => typeof(ServiceReference1.ICalculator);
    public void AddBindingParameters(ContractDescription contractDescription, ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
        return;
    }

    public void ApplyClientBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
        clientRuntime.ClientMessageInspectors.Add(new ClientMessageLogger());
    }
    public void ApplyDispatchBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, DispatchRuntime dispatchRuntime)
    {
        return;
    }

    public void Validate(ContractDescription contractDescription, ServiceEndpoint endpoint)
    {
        return;
    }
}

这是服务的示例代码：

 public class CustomMessageInspector : IDispatchMessageInspector
{
    public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
    {
        MessageHeader header = MessageHeader.CreateHeader("UserAgent", "http://User", "User1");
        request.Headers.Add(header);
        return null;
    }

    public void BeforeSendReply(ref Message reply, object correlationState)
    {
        MessageHeader header1 = MessageHeader.CreateHeader("Testreply", "http://Test", "Test");
        reply.Headers.Add(header1);
    }
}
[AttributeUsage(AttributeTargets.Interface)]
public class CustomBehavior : Attribute, IContractBehavior
{
    public void AddBindingParameters(ContractDescription contractDescription, ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
        return;
    }

    public void ApplyClientBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
        return;
    }
    public void ApplyDispatchBehavior(ContractDescription contractDescription, ServiceEndpoint endpoint, DispatchRuntime dispatchRuntime)
    {
        dispatchRuntime.MessageInspectors.Add(new CustomMessageInspector());
    }

    public void Validate(ContractDescription contractDescription, ServiceEndpoint endpoint)
    {
        return;
    }
}

要应用消息拦截器，您必须添加 CustomBehavior 功能，您可以使用客户端拦截器将其添加到客户端界面，并使用服务器端消息拦截器将其添加到服务器界面。

引用如下：IClientMessageInspector IDispatchMessageInspector

经过几天的搜索，我找到了这个的解决方案。另外，也不是因为客户端的输出有问题

将命名空间添加到 WCF 方法

Add namespace to WCF method

c#

wcf

soap

web-config
