WCF 웹 HTTP 서비스 도움말 페이지

2011-03-02

.NET Framework 버전 4에서는 WCF 웹 HTTP 서비스에 대한 자동 도움말 페이지를 제공합니다. 이 도움말 페이지에는 각 작업에 대한 설명, 요청 및 응답 형식, 스키마 등이 표시됩니다. 이 기능은 기본적으로 사용하지 않도록 설정되어 있습니다. 사용자가 WCF 웹 HTTP 서비스를 찾은 다음 https://localhost:8000/Customers/Help와 같이 해당 URL의 끝에 "/Help"를 추가하면 다음과 같은 도움말 페이지가 표시됩니다.

사용자가 이 도움말 페이지에 나열된 메서드를 클릭하면 메시지 형식과 예제 응답 등 메서드에 대한 자세한 내용을 보여 주는 해당 작업에 대한 상세 페이지가 표시됩니다. 다음 그림은 메서드에 대한 도움말 페이지의 예제입니다.

WCF 웹 HTTP 도움말 페이지 사용

WCF 웹 HTTP 도움말 페이지에는 DescriptionAttribute를 사용하여 지정한 작업에 대한 간략한 설명이 표시됩니다. 이 특성은 해당 특성이 적용되는 작업에 대한 간략한 설명이 포함된 문자열을 제공합니다. 예를 들어 다음 코드에서는 DescriptionAttribute를 사용하여 간략한 설명을 제공하는 방법을 보여 줍니다.

[OperationContract]
[WebGet(UriTemplate="/template1", BodyStyle = WebMessageBodyStyle.Bare)]
[Description("Description for GET /template1")]
SyndicationFeedFormatter GetTemplate1();

WCF 웹 HTTP 도움말 페이지를 사용하도록 설정하려면 서비스의 끝점에 끝점 동작을 추가해야 합니다. 이 작업은 구성 또는 코드에서 수행할 수 있습니다. 구성에서 WCF 웹 HTTP 도움말 페이지를 사용하도록 설정하려면 <webHttp> 요소를 사용하여 끝점 동작을 추가하고 enableHelp를 true로 설정합니다. 그런 다음 끝점을 추가하고 방금 추가한 끝점 동작을 사용하도록 구성합니다. 다음 구성 코드에서는 이 작업을 수행하는 방법을 보여 줍니다.

<endpointBehaviors>
   <behavior name="RESTEndpointBehavior">
      <webHttp enableHelp="true"/>
   </behavior>
</endpointBehaviors>
<!-- ... -->
<services>
   <service behaviorConfiguration="RESTWebServiceBehavior" name="RESTWebService">      <endpoint address="" kind="webHttpEndpoint" behaviorConfiguration="RESTEndpointBehavior" contract="IHello" />
      
      <!-- ... -->
   </service>
</services>

코드에서 WCF 웹 HTTP 도움말 페이지를 사용하도록 설정하려면 서비스 끝점을 추가하고 EnableHelp를 true로 설정한 다음 서비스 끝점에 WebHttpBehavior를 추가합니다. 다음 코드에서는 이 작업을 수행하는 방법을 보여 줍니다.

using (WebServiceHost host = new WebServiceHost(typeof(Service), new Uri("https://localhost:8000/Customers")))
{
   host.AddServiceEndpoint(typeof(ICustomerCollection), new WebHttpBinding(), "");             
   host.Description.Endpoints[0].Behaviors.Add(new WebHttpBehavior { EnableHelp = true });
   // ...
}

도움말 페이지는 해당 페이지의 여러 부분을 식별하는 태그가 포함된 XHTML을 기반으로 하기 때문에 클라이언트에서 XElement 또는 다른 XLinq API를 사용하여 프로그래밍 방식으로 액세스할 수 있습니다.
