MVC 基于角色的路由 [英] MVC role-based routing

问题描述

我有一个包含 2 个区域/Admin 和/User 的项目.

I have a project with 2 areas /Admin and /User.

管理员的默认路由是/Admin/Home/Index，用户的默认路由是/User/Home/Index.

Admin's default route is /Admin/Home/Index and user's default route is /User/Home/Index.

是否可以实现路由，使他们的主页 URL 看起来像 /Profile/Index，但向管理员和 /Admin/Home/Index 显示内容strong>/User/Home/Index 用户?

Is it possible to implement routing to make their home URL to look like /Profile/Index but to show content from /Admin/Home/Index for admins and /User/Home/Index for users?

更新

终于知道怎么做了

context.MapRoute(
    "Admin",
    "Profile/{action}",
    new { area = AreaName, controller = "Home", action = "Index" },
    new { RoleConstraint = new Core.RoleConstraint() },
    new[] { "MvcApplication1.Areas.Admin.Controllers" }
);
...
context.MapRoute(
    "User",
    "Profile/{action}",
    new { area = AreaName, controller = "Home", action = "Index" },
    new { RoleConstraint = new Core.RoleConstraint() },
    new[] { "MvcApplication1.Areas.User.Controllers" }
);

public class RoleConstraint : IRouteConstraint
{
    public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
    {
        string roleName = db.GetRoleByUserName(httpContext.User.Identity.Name);
        string areaName = route.Defaults["area"].ToString();
        return areaName == roleName;
    }
}

它有效，但对我来说这不是 MVC 方式.有人知道怎么做吗?

It works, but as for me it's not the MVC way. Does anybody knows how to do it right?

推荐答案

是的.您展示的示例与 Microsoft 提供的许多使用路由约束的示例非常接近.在请求传递到控件之前，路由引擎充当预代理(或路由器，如果您愿意).像 IRouteConstraint 这样的项目被定义，所以你可以按照你描述的做.

Yes. The example you showed is very close to many of the Microsoft provided samples for using Route Constraints. The routing engine acts as a pre-proxy (or router if you will) before the request is passed into a control. Items like IRouteConstraint are defined so you can do just what you described.
