所有 ASP.NET Web API 控制器都返回 404 [英] All ASP.NET Web API controllers return 404

问题描述

我正在尝试让 API 控制器在 ASP.NET MVC 4 Web 应用程序中工作.但是，每个请求都会导致 404，我很难过.:/

I'm trying to get an API Controller to work inside an ASP.NET MVC 4 web app. However, every request results in a 404 and I'm stumped. :/

我有来自项目模板的标准 API 控制器路由，定义如下:

I have the standard API controller route from the project template defined like:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

在 Global.asax 中调用注册:

The registration is invoked in Global.asax:

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    // Register API routes
    WebApiConfig.Register(GlobalConfiguration.Configuration);

    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);

    RouteConfig.RegisterRoutes(RouteTable.Routes);
}

我有一个像这样的基本 API 控制器:

I have a basic API controller like this:

namespace Website.Controllers
{
    public class FavoritesController : ApiController
    {       
        // GET api/<controller>
        public IEnumerable<string> Get()
        {
            return new [] { "first", "second" };
        }

        // PUT api/<controller>/5
        public void Put(int id)
        {

        }

        // DELETE api/<controller>/5
        public void Delete(int id)
        {

        }
    }
}

现在，当我浏览到 localhost:59900/api/Favorites 时，我希望调用 Get 方法，但我得到的是 404strong> 状态代码和以下响应:

Now, when I browse to localhost:59900/api/Favorites I expect the Get method to be invoked, but instead I get a 404 status code and the following response:

<Error>
   <Message>
       No HTTP resource was found that matches the request URI 'http://localhost:59900/api/Favorites'.
   </Message>
   <MessageDetail>
      No type was found that matches the controller named 'Favorites'.
   </MessageDetail>
</Error>

任何帮助将不胜感激，我在这里有点失去理智.:) 谢谢！

Any help would be greatly appreciated, I'm losing my mind a little bit over here. :) Thanks!

推荐答案

我遇到的一件事是我的配置在 GLobal.asax 文件中以错误的顺序注册，例如:

One thing I ran into was having my configurations registered in the wrong order in my GLobal.asax file for instance:

正确的顺序:

AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);

顺序错误:

AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
WebApiConfig.Register(GlobalConfiguration.Configuration);

只是说，这是我的问题，更改顺序很明显，但有时会被忽视，并会导致很多挫折.

Just saying, this was my problem and changing the order is obvious, but sometimes overlooked and can cause much frustration.
