wcf .svclog 文件中的所有消息体始终为 "... stream ..."，如何通过配置显示真实内容？

Question

我已经通过帮助链接的配置解决了记录用户名和密码的问题

消息记录的安全问题
http://msdn.microsoft.com/en-us/library/ms730318.aspx

但消息正文始终是“......流......”，

有没有办法通过配置或以编程方式解决这个问题？

我只想使用 SvcTraceViewer 工具查看“请求/响应详细的肥皂 xml”。

我已经看到了消息头和正文。我的问题是>>>
正文总是像“......流......”，我需要真正的内容而不仅仅是“......流......”。

Answer 1

是的，默认情况下，WCF 跟踪不会记录整个消息(仅SOAP header )

有许多选项可用于配置 WCF 跟踪。

logEntireMessage :指定是否记录整个消息(消息头和正文)。默认值为 false，表示仅记录 header 。

maxMessagesToLog :指定要记录的最大消息数。当达到配额时，将发出跟踪并且不记录其他消息。默认值为 10000。

maxSizeOfMessageToLog :指定要登录的消息的最大大小(以字节为单位)。超出大小限制的消息不会被记录。服务级别和传输级别消息的默认值为 256K，而格式错误消息的默认值为 4K。

一个非常基本的配置是

<system.diagnostics>
  <sources>
      <source name="System.ServiceModel.MessageLogging">
        <listeners>
                 <add name="messages"
                 type="System.Diagnostics.XmlWriterTraceListener"
                 initializeData="c:\logs\messages.svclog" />
          </listeners>
      </source>
    </sources>
</system.diagnostics>

<system.serviceModel>
  <diagnostics>
    <messageLogging 
         logEntireMessage="true" 
         logMalformedMessages="false"
         logMessagesAtServiceLevel="true" 
         logMessagesAtTransportLevel="false"
         maxMessagesToLog="3000"
         maxSizeOfMessageToLog="2000"/>
  </diagnostics>
</system.serviceModel>

编辑:

你在使用流媒体吗？在流式消息中，仅记录 header 。你无法改变这一点。为了查看正文内容，您唯一的选择就是禁用流媒体。
