Question

控制器：

public class DownloadListController : ApiController
{
    private MovieService _movieService;

    public DownloadListController()
    {
        _movieService = new MovieService();
    }

    public void Post([FromBody]string asd)
    {
        // Do something
    }

    public string Get()
    {
        return "test";
    }
}

Global.asax中

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

    // WebApiConfig.Register(GlobalConfiguration.Configuration);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    GlobalConfiguration.Configure(WebApiConfig.Register);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

WebApiConfig

public static void Register(HttpConfiguration config)
{
    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{action}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );

    // Uncomment the following line of code to enable query support for actions with an IQueryable or IQueryable<T> return type.
    // To avoid processing unexpected or malicious queries, use the validation settings on QueryableAttribute to validate incoming queries.
    // For more information, visit http://go.microsoft.com/fwlink/?LinkId=279712.
    //config.EnableQuerySupport();

    // To disable tracing in your application, please comment out or remove the following line of code
    // For more information, refer to: http://www.asp.net/web-api
    config.EnableSystemDiagnosticsTracing();
}

当我运行应用程序并浏览到http://localhost:4229/api/DownloadList时，我得到了404，而我在网络请求中看到的是GET请求。

当我向URI发出POST请求时，情况也是如此，结果是404.

我错过了什么？我需要做些什么来解决这个问题？

Answer 1

Web API不使用显式操作。它们由HTTP动词暗示。因此，您的{action}

中不应该有routeTemplate

routeTemplate: "api/{controller}/{id}",

使用MVC 5 Api控制器获得404
