WebApi發佈和路由在同一類

Question

我想學習WebApi並得到以下錯誤。

錯誤CS1929「HttpRequestBase」不包含關於「CreateResponse」和最好的擴展方法過載的定義「HttpRequestMessageExtensions.CreateResponse（HttpRequestMessage，HttpStatusCode，PilotModel）」需要類型

的「HttpRequestMessage」的接收器我想從我的Post方法返回一個HTTPResponseMessage，並且需要從WebApi繼承，但不能，因爲我從Controller繼承。我的班級設置有誤嗎？我不應該混合路由和WebApi呼叫？我該怎麼做？

public class RegistrationController : Controller 
{ 
    private RegistrationService registrationService; 

    public RegistrationController() 
    { 
     this.registrationService = new RegistrationService(); 
    } 

    public ActionResult Index() 
    { 
     ViewBag.Title = "Registration Page"; 

     return View(); 
    } 

    public HttpResponseMessage Post(PilotModel pilot) 
    { 
     this.registrationService.RegisterPilot(pilot); 

     var response = Request.CreateResponse<PilotModel>(HttpStatusCode.Created, pilot); 

     return response; 
    } 
}

您將需要兩個不同的控制器類。

namespace MyApp.Controllers 
{ 
    public class RegistrationController : Controller 
    { 
     private RegistrationService registrationService; 

     public RegistrationController() 
     { 
      this.registrationService = new RegistrationService(); 
     } 

     public ActionResult Index() 
     { 
      ViewBag.Title = "Registration Page"; 

      return View(); 
     } 
    } 
} 

你也可能需要添加[FromBody]來區分的pilot是從表格數據，而不是一個URL參數（假設你使用的是形式或在郵件正文中另有發送數據）。

namespace MyApp.ApiControllers 
{ 
    public class RegistrationController : ApiController 
    { 
     private RegistrationService registrationService; 

     public RegistrationController() 
     { 
      this.registrationService = new RegistrationService(); 
     } 

     public HttpResponseMessage Post([FromBody]PilotModel pilot) 
     { 
      this.registrationService.RegisterPilot(pilot); 

      var response = Request.CreateResponse<PilotModel>(HttpStatusCode.Created, pilot); 

      return response; 
     } 
    } 
}
