c# - 新的 WebApi 项目没有 API 的默认路由（但仍然有效）

Question

我创建了一个新的 WebAPI MVC 项目，API 控制器具有路径http://localhost:1234/api并且它们从该路由工作，但是RegisterRoutes该类不包含默认路由，它包含以下内容：

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 }
    );
}

API 的路由在哪里？

Answer 1

Visual Studio 项目模板创建一个默认路由，如下所示：

routes.MapHttpRoute(
   name: "API Default",
   routeTemplate: "api/{controller}/{id}",
   defaults: new { id = RouteParameter.Optional }
);

您可以在文件中找到它，该WebApiConfig.cs文件位于App_Start目录中

它住在不同的班级：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;

namespace HelloWorldApi
{
    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{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();
        }
    }
}
