在服务器上打开 IncludeExceptionDetailInFaults(来自 ServiceBehaviorAttribute 或来自 <serviceDebug> 配置行为)

问题描述

我有一个运行良好的 WCF 服务，但发生了一些变化，我不知道是什么.

I have a WCF service that has been working perfectly, and something has changed and I don't know what.

我得到了这个例外:

System.ServiceModel.FaultException:由于内部错误，服务器无法处理请求.有关错误的更多信息，请在服务器上打开 IncludeExceptionDetailInFaults(来自 ServiceBehaviorAttribute 或来自配置行为)以便将异常信息发送回客户端，或者根据 Microsoft .NET Framework 3.0 SDK 文档打开跟踪并检查服务器跟踪日志.

System.ServiceModel.FaultException: The server was unable to process the request due to an internal error. For more information about the error, either turn on IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute or from the configuration behavior) on the server in order to send the exception information back to the client, or turn on tracing as per the Microsoft .NET Framework 3.0 SDK documentation and inspect the server trace logs.

这很令人困惑，因为我运行的是 .NET 4.0.

This is confusing because I am running .NET 4.0.

在哪里打开 IncludeExceptionDetailInFaults?我正在努力寻找它.

Where do I turn on IncludeExceptionDetailInFaults? I'm battling to find it.

推荐答案

定义一个行为 在您的 .config 文件中:

Define a behavior in your .config file:

<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="debug">
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    ...
  </system.serviceModel>
</configuration>

然后按照以下方式将行为应用于您的服务:

Then apply the behavior to your service along these lines:

<configuration>
  <system.serviceModel>
    ...
    <services>
      <service name="MyServiceName" behaviorConfiguration="debug" />
    </services>
  </system.serviceModel>
</configuration>

您也可以通过编程方式进行设置.请参阅这个问题.

You can also set it programmatically. See this question.
