相当于存储在数据库中的 Fiddler SOAP 请求/响应

问题描述

我写了很多 WCF 服务给其他服务.我之前在让 Fiddler 记录 SOAP 消息时遇到了麻烦，但现在我可以正常工作了.但是我的老板想要一些完全没有 Fiddler 的东西，我可以将 SOAP 消息传出去，而进来的消息则记录到数据库中.我已经看了很多 WCF 日志记录和诊断并使用数据库源侦听器对其进行了扩展，但是我找不到要使用的数据库源侦听器的实现.

I write a lot of WCF services to other services. I have had trouble with getting Fiddler to log the SOAP messages before but now I have that working. But my boss wants something without Fiddler at all where I can take the SOAP message going out and the one coming in logged to the database. I have looked a lot at WCF Logging and Diagnostics and extending it with Database Source Listener but I cant find an implementation of a Database Source Listener to use.

我认为这甚至不是他想要的.他希望将 Fiddler 的 SOAP 请求/响应显示等价物写入数据库.有人可以帮我吗?

I don't think that's what he even wants. He wants the equivalent of Fiddler's SOAP request/response displays written to the database. Can anyone help me please?

推荐答案

你有两种可能:

1. 编写自定义WCFTrace Listener，调用数据库过程存储日志数据:

1. Write custom WCF Trace Listener, calling database procedure to store logging data:

public class AsyncMSMQTraceListener : TraceListener
{
    public override void TraceData(TraceEventCache eventCache, string source,
                                   TraceEventType eventType, int id, object data)
    {
       // eventType like for example TraceEventType.Information
       var message = data.ToString();

       // Here call datbase save log with message              
    }


    public override void Write(string message)
    {
    }

    public override void WriteLine(string message)
    {
    }
}

但通过这种方式，您将获得跟踪消息，其中请求/响应只是其中的一部分.

but in this way you'll get trace messages, where request/response is only a part of it.

编写自定义消息检查员类:

public class ConsoleOutputMessageInspector : IDispatchMessageInspector
{
    public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
    {
        MessageBuffer buffer = request.CreateBufferedCopy(Int32.MaxValue);
        request = buffer.CreateMessage();

        // Here you can use buffer.CreateMessage().ToString()

        return null;
    }

    public void BeforeSendReply(ref Message reply, object correlationState)
    {
        MessageBuffer buffer = reply.CreateBufferedCopy(Int32.MaxValue);
        reply = buffer.CreateMessage();

        // here you can use buffer.CreateMessage().ToString()
    }
}

注意:无论您选择哪种方法，我都建议对数据库进行某种异步调用，以免阻塞正常的服务流.

Note: Regardless which method you choose, I would suggest to make some kind of an asynchronous call to the database to not block normal service flow.
