WebApi Post和Routing在同一类中

本文关键字：一类 Post Routing WebApi | 更新日期: 2023-09-27 18:28:04

我正在尝试学习WebApi，但收到以下错误。

错误CS1929"HttpRequestBase"不包含"CreateResponse"的定义，并且最佳扩展方法重载"HttpRequestMessageExtensions。CreateResponse（HttpRequestMessage、HttpStatusCode、PilotModel）"需要类型为"HttpRequestMessage"的接收器

我想从Post方法返回HTTPResponseMessage，并且需要从WebApi继承，但不能，因为我是从Controller继承的。我的课程设置不正确吗？我不应该把路由和WebApi电话混在一起吗？我该怎么做？

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消息正文中发送数据）。

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;
        }
    }
}
