web api 2 路由 - 找不到资源 [英] web api 2 routing - The resource cannot be found

问题描述

我已将 Web Api 控制器添加到 MVC 5 应用程序，但我一直收到错误 404 - 找不到资源.我已将 GlobalConfiguration.Configure(WebApiConfig.Register) 添加到 Application_Start()

I've added Web Api controller to MVC 5 application but all the time I get Error 404 - The resource cannot be found. I've added GlobalConfiguration.Configure(WebApiConfig.Register) to Application_Start()

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
        GlobalConfiguration.Configure(WebApiConfig.Register);
    }

我已经注册了路线

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

推荐答案

WebApi 路由在我将 Register api 方法的位置更改为 register 路由的上方后开始工作:

WebApi routing started to work after I've changed the position of Register api method to be above of register routes:

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        GlobalConfiguration.Configure(WebApiConfig.Register);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
