【问题描述】：

出现以下错误：

由于内部错误，服务器无法处理请求。有关该错误的更多信息，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 SDK 文档打开跟踪并检查服务器跟踪日志。

这是我的 WCF web.config 文件：

【参考方案1】：

您的 WCF 服务引发异常。在您的 WCF 配置中更改此项以从服务获取异常消息：

      <serviceDebug includeExceptionDetailInFaults="true"/>

在部署到生产环境时，您需要将其改回 false。
