我的簡單的API控制器動作似乎沒有工作

Question

我試圖在瀏覽器中查看我的API控制器動作，我似乎無法找到此endpiont解析的URL。我想：

http://localhost:2797/api/Country/Testing  
http://localhost:2797/api/Country/GetTesting  

我得到這個錯誤：

<Error> 
<Message> 
The requested resource does not support http method 'GET'. 
</Message> 
</Error> 


public class CountryController : ApiController 
    { 
     public HttpResponseMessage Testing() 
     { 
      HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, "value"); 
      response.Content = new StringContent("hello", System.Text.Encoding.Unicode); 
      response.Headers.CacheControl = new CacheControlHeaderValue() 
      { 
       MaxAge = TimeSpan.FromMinutes(20) 
      }; 

      return response; 
     } 

    } 

Answer 1

上Testing方法

[HttpGet] 
public HttpResponseMessage Testing() 

的頂部添加[HttpGet]或方法名稱添加Get

public HttpResponseMessage GetTesting()

然後它應該可以通過 http://localhost:2797/api/Country/Testing
