Question

我创建了Windows服务，并使用installutil.exe安装了它。

但是，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被禁用。”

您能帮我解决这个问题吗？

下面是我的App.Config文件

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mReactRootView = new ReactRootView(this);
        mReactInstanceManager = ReactInstanceManager.builder()
                .setApplication(getApplication())
                .setBundleAssetName("index.android.bundle")
                 .setJSMainModulePath("index.android")
                .addPackage(new MainReactPackage())
                .setUseDeveloperSupport(BuildConfig.DEBUG)
                .setInitialLifecycleState(LifecycleState.BEFORE_RESUME)
                .build();
        mReactRootView.startReactApplication(mReactInstanceManager, "AwesomeReactApp", null);
        setContentView(mReactRootView);

尽管我们已经设置了httpGetEnabled属性，但是我们需要设置HTTP基址来启用serviceMetadata属性。
请参考下面的代码段。

  <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>

请随时让我知道问题是否仍然存在。

static void Main(string[] args)
        {
            Uri uri = new Uri("http://localhost:21011");
            BasicHttpBinding binding = new BasicHttpBinding();
            using (ServiceHost sh = new ServiceHost(typeof(MyService), uri))
            {
                sh.AddServiceEndpoint(typeof(IService), binding, "");
                ServiceMetadataBehavior smb;
                smb = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
                if (smb == null)
                {
                    smb = new ServiceMetadataBehavior()
                    {
                        HttpGetEnabled = true
                    };
                    sh.Description.Behaviors.Add(smb);
                }
                Binding mexbinding = MetadataExchangeBindings.CreateMexHttpBinding();
                sh.AddServiceEndpoint(typeof(IMetadataExchange), mexbinding, "mex");
                sh.Opened += delegate
                {
                    Console.WriteLine("Service is ready");
                };
                sh.Closed += delegate
                {
                    Console.WriteLine("Service is clsoed");
                };
                sh.Open();
                Console.ReadLine();
                //pause
                sh.Close();
                Console.ReadLine();
            }

即使HTTPGetEnabled设置为true，也无法访问WSDL
