Question

我正在调用网址＆＃34; localhost / Student / 1＆＃34;返回id = 1的学生。我的路线配置：

routes.MapRoute(
               name: "StudentID",
               url: "Student/{id}",
               defaults: new { controller = "Student", action = "Get}
           );

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

public class StudentController : Controller
    {
        // GET: Student
        [Authorize]
        public ActionResult Index()
        {
            SchoolDbEntities db = new SchoolDbEntities();
            return View(db.Students);
        }
        [Route("Student/{id}")]
        [ActionName("Get")]
        public ActionResult Get(int id)
        {
            SchoolDbEntities db = new SchoolDbEntities();
            var student = db.Students.Where(s => s.Id == id);
            return View(student);
        }
    }

我配置了路由表并使用路由属性。但是，当我运行应用程序时，它会抛出一个错误：无法找到资源。

我如何实现与使用webapi相同的功能。

Answer 1

如果要在MVC中使用属性路由，则必须在routes.MapMvcAttributeRoutes()类中调用RouteConfig来注册它们。

请注意，注册顺序很重要。通过在route.MapMvcAttributeRoutes()呼叫之前调用routes.MapRoute()，MVC将查看传统路由之前的属性路由。第一条匹配路线获胜。

routes.MapMvcAttributeRoutes();

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

在您的控制器中设置属性路由，如下所示：

[RoutePrefix("Student")]    
public class StudentController : Controller
    {
        // GET: Student
        [Authorize]
        public ActionResult Index()
        {
            SchoolDbEntities db = new SchoolDbEntities();
            return View(db.Students);
        }

        [Route("{id}")]
        public ActionResult Get(int id)
        {
            SchoolDbEntities db = new SchoolDbEntities();
            var student = db.Students.Where(s => s.Id == id);
            return View(student);
        }
    }

这将匹配URL＆＃34; Student / 1＆＃34;。

我想在mvc
