如何创建“ / <Controller> / {id1} / <Action> / {id2}”这样的路线在剃须刀页面中？

Question

I have a requirement where I have to create a route like /Class/10/Student/134 to get an information of a student whose role id is 134 and whose class id is 10. How can I create such a route in Razor pages?

I have added the following route in Startup.cs

routes.MapRoute(
    name: "GetStudentFromClass",
    template: "Class/{classId}/Student/{studentId?}",
    defaults: new
    {
        controller = "Class",
        action = "Student"
    }
);

and my pages directory structure is like

- /Pages
  - /Class
    - Student.cshtml
    - Student.cshtml.cs

In Student.cshtml, I have added this @page "{classId:int}/Student/{studentId:int?}" to first line

But it is not working. Any suggestions, where I did wrong?

Answer 1

The mapRoute method is for defining MVC routes. Razor Pages routing is handled a little differently. You should only need to define a template as part of the @page directive. In this case, it should be:

@page "/Class/{classid:int}/Student/{studentid:int}"

There is no need to add anything to the Startup file.
