在Azure中创建WCF服务时如何配置webHttp绑定？

Question

我正在Azure中开发WCF WebRole服务，需要调用一种以JSON格式提供员工数据的方法。但是与普通的WCF Web服务不同，我不知道如何为WCF Webrole和我的代码配置“ Web.config”常规WCF服务的“ Web.config”如下：

<system.serviceModel>
<services>
  <service name="empl.Service1" behaviorConfiguration="empl.Service1Behavior">
    <!-- Service Endpoints -->
    <endpoint  address="" binding="webHttpBinding" contract="empl.IService1" behaviorConfiguration="web">
      <!-- 
          Upon deployment, the following identity element should be removed or replaced to reflect the 
          identity under which the deployed service runs.  If removed, WCF will infer an appropriate identity 
          automatically.
      -->
      <identity>
        <dns value="localhost"/>
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
  </service>
</services>
<behaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp/>
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="empl.Service1Behavior">
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
      <serviceMetadata httpGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

WCF WebRole（Azure）的代码“ Web.config”如下

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior>
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
      <serviceMetadata httpGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" /></system.serviceModel>

现在，我需要获取URI访问“ http：//localhost/Service1.svc/GetId”，该访问应以JSON数据响应。 但是对我来说，这表明“ HTTP400错误请求”。 帮帮我。

错误的请求可能是所发送的请求无效。 如果无法访问或发现您的服务，则可能是其他Http错误代码。 尝试对您的服务启用跟踪，以查看请求错误的原因。 要启用跟踪，请点击此链接
