即使 HTTPGetEnabled 设置为 true，也无法访问 WSDL

Question

我创建了一个 Windows 服务并使用 installutil.exe 安装它。

但即使 HTTPGetEnabled 设置为 true，我也无法访问“MEX”端点。 总是收到错误“此服务的元数据发布当前已禁用。”

你能帮我解决这个问题吗？

下面是我的 App.Config 文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
      <behaviors>
        <serviceBehaviors>
          <behavior name ="MyBehaviour">
            <serviceMetadata httpGetEnabled="true"/>
          </behavior>
        </serviceBehaviors>
      </behaviors>
        <services>
            <service name="GenerateResult.GenerateResult" behaviorConfiguration="MyBehaviour">
                <endpoint address="http://localhost:5050/GetResultService" binding="basicHttpBinding"
                    bindingConfiguration="" contract="GenerateResult.IGenerateResult" />
                <endpoint address="http://localhost:5050/GetResultService/mex" 
                    binding="mexHttpBinding"
                    bindingConfiguration="" contract="IMetadataExchange" />
        </service>    
    </services>
</system.serviceModel>

尽管我们已经设置了serviceMetadata 属性，但我们需要设置一个HTTP 基地址来启用httpGetEnabled 属性。
请参考以下代码段。

  <system.serviceModel>
    <services>
      <service  name="ConsoleApp3.TestService" behaviorConfiguration="mybeh"> 
        <endpoint address="myservice" binding="basicHttpBinding" contract="ConsoleApp3.ITestService" bindingConfiguration=""></endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" bindingConfiguration=""></endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:21011/"/>
          </baseAddresses>
        </host>
      </service>
    </services>
    <bindings>
   <basicHttpBinding>
   </basicHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="mybeh">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

如果问题仍然存在，请随时告诉我。
