Error info:
WS-Metadata Exchange Error
    URI: http://localhost:8080/WCFTest/Service.svc
HTTP GET Error
    URI: http://localhost:8080/WCFTest/Service.svc

在service的web.config中添加
 <behaviors>
      <serviceBehaviors>
        <behavior name="returnFaults" >
          <serviceMetadata httpGetEnabled="true" />
    <serviceMetadata httpGetEnabled="true" />
</behavior>
 </serviceBehaviors>
</behaviors>

即可。
