如何获取WCF Web服务请求的XML SOAP请求？

Question

我在代码中调用此Web服务,我希望看到XML,但我找不到暴露它的属性.

Answer 1

我想你的意思是你想在客户端看到XML,而不是在服务器上跟踪它.在这种情况下,您的答案在我上面链接的问题中,以及如何检查或修改客户端上的消息.但是,由于该文章的.NET 4版本缺少其C#,并且.NET 3.5示例中存在一些混淆(如果不是错误),这里它会针对您的目的进行扩展.

您可以使用IClientMessageInspector拦截消息:

using System.ServiceModel.Dispatcher;
public class MyMessageInspector : IClientMessageInspector
{ }

该接口中的方法,BeforeSendRequest并AfterReceiveReply允许您访问请求和回复.要使用检查器,您需要将其添加到IEndpointBehavior:

using System.ServiceModel.Description;
public class InspectorBehavior : IEndpointBehavior
{
    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
        clientRuntime.MessageInspectors.Add(new MyMessageInspector());
    }
}

您可以将该接口的其他方法保留为空实现,除非您也想使用它们的功能.阅读操作方法以获取更多详细信息.

实例化客户端后,将行为添加到端点.使用示例WCF项目中的默认名称:

ServiceReference1.Service1Client client = new ServiceReference1.Service1Client();
client.Endpoint.Behaviors.Add(new InspectorBehavior());
client.GetData(123);

设置断点MyMessageInspector.BeforeSendRequest(); request.ToString()重载以显示XML.

如果您要操纵消息,则必须处理消息的副本.有关详细信息,请参阅使用消息类.

Answer 2

选项1

使用邮件跟踪/日志记录.

看看这里和这里.

选项2

您始终可以使用Fiddler查看HTTP请求和响应.

选项3

使用System.Net跟踪.

Answer 3

OperationContext.Current.RequestContext.RequestMessage 

在处理请求期间,此上下文是可访问的服务器端.这不适用于单向操作

Answer 4

我们只需跟踪请求消息即可.

OperationContext context = OperationContext.Current;

if (context != null && context.RequestContext != null)

{

Message msg = context.RequestContext.RequestMessage;

string reqXML = msg.ToString();

}

Answer 5

我只是想将此添加到金伯利的答案中。也许它可以节省一些时间并避免由于未实现 IEndpointBehaviour 接口所需的所有方法而导致的编译错误。
