如何拦截来自WCF客户端的原始soap请求/响应（数据）

This question seems to be pretty close to what I am looking for - I was able to setup tracing and I am looking at the log entries for my calls to the service.

这个问题似乎与我正在寻找的非常接近 - 我能够设置跟踪，我正在查看我对服务的调用的日志条目。

However I need to see the raw soap request with the data I am sending to the service and I see no way of doing that from the SvcTraceViewer (only log entries are shown but no data sent to the service) - am I just missing configuration?

但是，我需要查看原始soap请求以及我发送给服务的数据，并且我看不到从SvcTraceViewer执行此操作（仅显示日志条目但没有数据发送到服务） - 我只是缺少配置？

Here's what I got in my web.config:

这是我在web.config中得到的：

  <system.diagnostics>
    <sources>
      <source name="System.ServiceModel"
              switchValue="Verbose"
              propagateActivity="true">
        <listeners>
          <add name="sdt"
              type="System.Diagnostics.XmlWriterTraceListener"
              initializeData="App_Data/Logs/WCFTrace.svclog"  />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>

Any help appreciated!

You don't have a specific tab that shows just the SOAP message - but the XML tab does include the whole SOAP message - no??

您没有显示SOAP消息的特定选项卡 - 但XML选项卡确实包含整个SOAP消息 - 没有？

What is missing for you from this snippet of XML here??

你在这个XML片段中缺少什么？

UPDATE: John, you're unfortunately not showing what your <system.serviceModel>/<diagnostics> section looks like - mine used for this result looks like this:

更新：John，遗憾的是你没有显示你的 / 部分是什么样的 - 我用于此结果的内容如下所示：

<diagnostics>
  <messageLogging 
      logMessagesAtTransportLevel="true" 
      logMessagesAtServiceLevel="false"
      logMalformedMessages="true" 
      logEntireMessage="true"
      maxSizeOfMessageToLog="65535000" 
      maxMessagesToLog="500" />
</diagnostics>

Do you have the same settings? Maybe you're missing logEntireMessage or something else??

你有相同的设置吗？也许你错过了logEntireMessage或其他什么？

I recently encountered the same problem as in the update to the original question: the trace was showing that a message had been sent, but the message itself wasn't there. For me, the fix was to add a System.ServiceModel.MessageLogging source. Here's my system.diagnostics config section:

我最近遇到了与原始问题更新中相同的问题：跟踪显示已发送消息，但消息本身不存在。对我来说，修复是添加System.ServiceModel.MessageLogging源。这是我的system.diagnostics配置部分：

<system.diagnostics>
   <sources>
      <source name="System.ServiceModel" 
              switchValue="Information, ActivityTracing" 
              propagateActivity="true" >
         <listeners>
            <add name="xml"/>
         </listeners>
      </source>
      <source name="System.ServiceModel.MessageLogging">
         <listeners>
            <add name="xml"/>
         </listeners>
      </source>
   </sources>
   <sharedListeners>
      <add name="xml" 
           type="System.Diagnostics.XmlWriterTraceListener" 
           initializeData="C:\logfiles\Traces.svclog" />
   </sharedListeners>
</system.diagnostics>

And my system.serviceModel / diagnostics section:

我的system.serviceModel / diagnostics部分：

<diagnostics>
   <messageLogging
      logMessagesAtTransportLevel="true"
      logMessagesAtServiceLevel="true"
      logMalformedMessages="true"
      logEntireMessage="true"
      maxSizeOfMessageToLog="65535000"
      maxMessagesToLog="500" />
</diagnostics>

Once I added the MessageLogging source, the TraceViewer showed "Message Log Trace" traces which contained the actual SOAP messages.

一旦我添加了MessageLogging源，TraceViewer就显示了包含实际SOAP消息的“消息日志跟踪”跟踪。

There is an another way to see XML SOAP - custom MessageEncoder. The main difference from IDispatchMessageInspector / IClientMessageInspector is that it works on lower level, so it captures original byte content including any malformed xml.

还有另一种方法可以查看XML SOAP - 自定义MessageEncoder。与IDispatchMessageInspector / IClientMessageInspector的主要区别在于它在较低级别上工作，因此它捕获原始字节内容，包括任何格式错误的xml。

In order to implement tracing using this approach you need to wrap a standard textMessageEncoding with custom message encoder as new binding element and apply that custom binding to endpoint in your config.

为了使用此方法实现跟踪，您需要将标准textMessageEncoding与自定义消息编码器包装为新绑定元素，并将该自定义绑定应用于配置中的端点。

Also you can see as example how I did it in my project - wrapping textMessageEncoding, logging encoder, custom binding element and config.

你也可以看看我在项目中是如何做到的 - 包装textMessageEncoding，记录编码器，自定义绑定元素和配置。
