在一个路由中指定多个控制器

Question

在我们的 ASP.NET MVC 架构中，我们有以下路由结构：

http://localhost:80/Students/Details/2 - will give me details about student with id == 2, details include all the classes current student have.

http://localhost:80/Classes/Details/2 - will give me details about classes with id == 2, details include all the students current class have.

http://localhost:80/Schedule/Details/class=2&student=2 - will give me details about specific schedule for student with id=2 that has class with id=2

到目前为止，这工作正常。

现在，我们的团队对 asp.net mvc 还很陌生，我们正在考虑让路由更直观一些。因此，我们将有一条长路线，而不是三条单独的路线，如下所示：

http://localhost:80/Students/2/Classes/2/Homework/ 

它会像这样工作：

http://localhost:80/Students/ - will give list of students
http://localhost:80/Students/2 - will give details about student 2
http://localhost:80/Students/2/Classes - will give all the classes for student with id 2
http://localhost:80/Students/2/Classes/2 - will give schedule for class with id 2 and student with id 2. 

不确定这是否合理/可能，只是想获得更多意见

MVC 路由映射到控制器类中的单个操作。
您可以为每个案例配置一个路由，映射到每个案例的不同操作。请记住，路由应按从更具体到更通用的顺序排列。

在您的 App_Start/RouteConfig.cs 中：

        routes.MapRoute(
            name: "StudentSchedule",
            url: "students/{studentID}/classes/{classID}",
            defaults: new { controller = "Home", action = "StudentSchedule" }
        );
        routes.MapRoute(
            name: "StudentClasses",
            url: "students/{studentID}/classes",
            defaults: new { controller = "Home", action = "StudentClasses" }
        );
        routes.MapRoute(
            name: "StudentDetails",
            url: "students/{studentID}",
            defaults: new { controller = "Home", action = "StudentDetails" }
        );
        routes.MapRoute(
            name: "StudentsList",
            url: "students",
            defaults: new { controller = "Home", action = "Students" }
        );

因此，您的操作将如下所示，您必须添加代码以从数据库中获取数据，您可以在应用程序的单独类/层上共享代码：

    public ActionResult Students()
    {
        var viewmodel = new StudentsViewModel();
        ...
        return View(viewmodel);
    }

    public ActionResult StudentDetails(int studentID)
    {
        var viewmodel = new StudentDetailsViewModel();
        ...
        return View(viewmodel);
    }

    public ActionResult StudentClasses(int studentID)
    {
        var viewmodel = new StudentClassesViewModel();
        ...
        return View(viewmodel);
    }

    public ActionResult StudentSchedule(int studentID, int classID)
    {
        var viewmodel = new StudentScheduleViewModel();
        ...
        return View(viewmodel);
    }
