Answers:
我认为您的意思是您想在客户端看到XML,而不是在服务器上跟踪它。在这种情况下,您的答案将在上面我链接的问题中,以及如何在客户端上检查或修改消息中。但是,由于该文章的.NET 4版本缺少C#,并且.NET 3.5示例中有些混乱(如果不是错误的话),因此此处将其扩展为您的用途。
您可以使用IClientMessageInspector拦截消息,然后再将其发送出去:
using System.ServiceModel.Dispatcher;
public class MyMessageInspector : IClientMessageInspector
{ }
该界面中的方法BeforeSendRequest
和AfterReceiveReply
,使您可以访问请求和答复。要使用检查器,您需要将其添加到IEndpointBehavior中:
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的实现,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);
在中设置一个断点MyMessageInspector.BeforeSendRequest()
;request.ToString()
重载以显示XML。
如果要完全处理消息,则必须处理消息的副本。有关详细信息,请参见使用消息类。
感谢Zach Bonham对另一个找到这些链接的问题的回答。
OperationContext.Current.RequestContext.RequestMessage
该上下文是请求处理期间可访问的服务器端。这不适用于单向操作
我只是想将此添加到Kimberly的答案中。也许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。
最好的祝福

我将以下解决方案用于ASP.NET兼容模式下的IIS托管。感谢Rodney Viana的MSDN博客。
在appSettings下将以下内容添加到您的web.config中:
<add key="LogPath" value="C:\\logpath" />
<add key="LogRequestResponse" value="true" />
将您的global.asax.cs替换为以下内容(还修复名称空间名称):

它应在带有请求和响应XML的LogPath文件夹中创建日志文件。
