Routing 不使用基于约定的路由的web api属性路由

我在一个解决方案中有web api（owin托管）和MVC项目。如果基于约定但属性路由不起作用，则我的web api路由可以工作。为了测试属性路由，我删除了web api路由的默认基于约定的配置。我有以下条目

startup.cs

public partial class Startup
 {

   public void Configuration(IAppBuilder app)
   { 
    var config = new HttpConfiguration();
     app.Map("/api", inner =>
        {
            ConfigureWebApi(config);
            inner.UseWebApi(config);
        });
   }

   public void ConfigureWebApi(HttpConfiguration config)
   {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();
   } // no default convention based routing

public class ProductsController : ApiController
 {
    [Route("api/products")]
    public IHttpActionResult Get()
    {

    }

     [Route("api/products/TopCategories"),HttpGet]
    public IHttpActionResult GetTopCategories()
    {

    }
 }

public class RouteConfig
 {
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        //web api routes from startup.cs
        //GlobalConfiguration.Configure(WebApiConfig.Register);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
}

ProductsController.cs

public partial class Startup
 {

   public void Configuration(IAppBuilder app)
   { 
    var config = new HttpConfiguration();
     app.Map("/api", inner =>
        {
            ConfigureWebApi(config);
            inner.UseWebApi(config);
        });
   }

   public void ConfigureWebApi(HttpConfiguration config)
   {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();
   } // no default convention based routing

public class ProductsController : ApiController
 {
    [Route("api/products")]
    public IHttpActionResult Get()
    {

    }

     [Route("api/products/TopCategories"),HttpGet]
    public IHttpActionResult GetTopCategories()
    {

    }
 }

public class RouteConfig
 {
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        //web api routes from startup.cs
        //GlobalConfiguration.Configure(WebApiConfig.Register);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
}

我不想依赖MVC路由实现web api，但万一这里缺少什么，请告诉我

routeconfig.cs

public partial class Startup
 {

   public void Configuration(IAppBuilder app)
   { 
    var config = new HttpConfiguration();
     app.Map("/api", inner =>
        {
            ConfigureWebApi(config);
            inner.UseWebApi(config);
        });
   }

   public void ConfigureWebApi(HttpConfiguration config)
   {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();
   } // no default convention based routing

public class ProductsController : ApiController
 {
    [Route("api/products")]
    public IHttpActionResult Get()
    {

    }

     [Route("api/products/TopCategories"),HttpGet]
    public IHttpActionResult GetTopCategories()
    {

    }
 }

public class RouteConfig
 {
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        //web api routes from startup.cs
        //GlobalConfiguration.Configure(WebApiConfig.Register);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
}

Global.asax.cs

public partial class Startup
 {

   public void Configuration(IAppBuilder app)
   { 
    var config = new HttpConfiguration();
     app.Map("/api", inner =>
        {
            ConfigureWebApi(config);
            inner.UseWebApi(config);
        });
   }

   public void ConfigureWebApi(HttpConfiguration config)
   {
        // Web API configuration and services

        // Web API routes
        config.MapHttpAttributeRoutes();
   } // no default convention based routing

public class ProductsController : ApiController
 {
    [Route("api/products")]
    public IHttpActionResult Get()
    {

    }

     [Route("api/products/TopCategories"),HttpGet]
    public IHttpActionResult GetTopCategories()
    {

    }
 }

public class RouteConfig
 {
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );
    }
}

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        //web api routes from startup.cs
        //GlobalConfiguration.Configure(WebApiConfig.Register);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);
    }
}

我使用了routeprefix，但出于测试目的删除了它。 我认为下面两个Url都应该工作，但由于某些原因，它们不工作，我得到404错误

(一) 2）

基于堆栈跟踪，出于某种原因，我认为我的MVC路由正在处理“/api”路由（我可能错了）

您是否希望将常量字符串“api”添加到uri两次？一次在app.map中，一次在route属性中。你试过api/api/产品吗？你是对的，比尔，api/api/产品有效。我修复了我的属性并从中删除了api。再次感谢。看起来您会两次向uri添加常量字符串“api”吗？一次在app.map中，一次在route属性中。你试过api/api/产品吗？你是对的，比尔，api/api/产品有效。我修复了我的属性并从中删除了api。再次感谢。
