Question

我正在尝试学习WebApi并且遇到以下错误。

错误CS1929'HttpRequestBase'不包含'CreateResponse'的定义，最好的扩展方法重载'HttpRequestMessageExtensions.CreateResponse（HttpRequestMessage，HttpStatusCode，PilotModel）'需要一个'HttpRequestMessage'类型的接收器

我想从我的Post方法返回一个HTTPResponseMessage，并且需要从WebApi继承，但不能，因为我继承自Controller。我的班级设置不正确吗？我不应该混合路由和WebApi调用吗？我该怎么办？

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;
    }
}

您将需要两个不同的控制器类。

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();
        }
    }
}

您可能还需要添加[FromBody]以区分pilot来自表单数据而不是URL参数（假设您正在使用表单或以其他方式在表单中发送数据）消息）。

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;
        }
    }
}

WebApi在同一类中发布和路由
