c# - 创建 wcf 服务后，如何从 wsdl 判断它是 Restful 还是 SOAP 的？

Question

我创建了一个服务，我看到一个页面说:

You have created a service.

To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:

但是我如何判断它是 SOAP 还是 REST 服务呢？我如何从 wsdl 等中分辨出来？

服务配置:

<services> 
    <service name="VLSContentService"
             behaviorConfiguration="VLSContentServiceBehaviour" > 
        <endpoint name="rest" 
            address="" 
            behaviorConfiguration="VLSContentServiceEndpointBehaviour" 
            binding="webHttpBinding" 
            contract="IVLSContentServiceREST" /> 
        <endpoint name="soap" 
            address="soap" 
            binding="basicHttpBinding" 
            contract="IVLSContentServiceREST"/> 
    </service> 
</services>

更新:

嗨，马克，

我的配置是:

 <services>
      <service behaviorConfiguration="VLSContentServiceBehaviour" name="VLSContentService">
        <endpoint name="rest" address="" behaviorConfiguration="VLSContentServiceEndpointBehaviour" binding="webHttpBinding" contract="IVLSContentServiceREST" />
        <endpoint name="soap" address="soap" binding="basicHttpBinding" contract="IVLSContentServiceREST"/>
      </service>
    </services>

所以基本上我浏览到 .svc 文件，我看到了一个 wsdl 的链接。但是我怎么知道那是用于 SOAP 还是 REST 端点。我是否正确配置了它？

谢谢

<system.serviceModel>

  <!---Add the service-->
  <services>
    <service behaviorConfiguration="VLSContentServiceBehaviour" name="VLSContentService">
       <endpoint name="rest" 
           address="" 
           behaviorConfiguration="VLSContentServiceEndpointBehaviour" 
           binding="webHttpBinding" 
           contract="IVLSContentServiceREST" />
    </service>
 </services>
 <!---Add the behaviours-->
 <behaviors>
    <serviceBehaviors>
       <behavior name="VLSContentServiceBehaviour">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
       </behavior>
    </serviceBehaviors>
    <endpointBehaviors>
       <behavior name="VLSContentServiceEndpointBehaviour">
         <webHttp />
       </behavior>
    </endpointBehaviors>
  </behaviors>
  <serviceHostingEnvironment aspNetCompatibilityEnabled="false" />
</system.serviceModel>

Pete，试试这个 - 没有元数据发布，什么都没有 - 只是 webHttpBinding - 你应该不再看到任何 WSDL...

<system.serviceModel>
   <services>
      <service name="VLSContentService">
          <endpoint name="rest" 
              address="" 
              binding="webHttpBinding" 
              contract="IVLSContentServiceREST" />
      </service>
   </services>
   <serviceHostingEnvironment aspNetCompatibilityEnabled="false" />
</system.serviceModel>

服务可以是 REST 和 SOAP，WCF 服务可以有多个端点，包括两者的混合 SOAP 和休息。在 WSDL 上，SOAP 端点将显示在 wsdl:definitions/wsdl:service/wsdl:port 元素中； REST 端点不会。因此，如果您在服务中只有一个端点，如果 WSDL 中有一个 wsdl:port 条目，那么它就是一个 SOAP 端点；否则就是 REST。

您可以运行下面的代码并查看 wsdl 以查看它只显示一个 wsdl:port 元素，用于 SOAP 端点。

    public interface ITest
    {

        [WebGet]
        string Echo(string text);
    }
    public class Service : ITest
    {
        public string Echo(string text)
        {
            return text;
        }
    }
    public static void Test()
    {
        string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
        ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress));
        host.Description.Behaviors.Add(new ServiceMetadataBehavior { HttpGetEnabled = true });
        host.AddServiceEndpoint(typeof(ITest), new BasicHttpBinding(), "soap");
        host.AddServiceEndpoint(typeof(ITest), new WebHttpBinding(), "rest").Behaviors.Add(new WebHttpBehavior());
        host.Open();
        Console.WriteLine("Host opened");

        Console.Write("Press ENTER to close the host");
        Console.ReadLine();
        host.Close();
    }
}
