asp.net - tag-helpers 未正确生成我的网址

Question

我设置了以下路线

    app.UseMvc(routes =>
    {

        routes.MapRoute(
            name: "admin",
            template: "{controller=Home}/{action=Index}/{id?}",
            defaults: new {Area = "Admin"},
            constraints: new {HostConstraint = new MyConstraint()});
        routes.MapRoute(
            name: "admin-rep",
            template: "Rep/{controller=Home}/{action=Index}/{id?}",
            defaults: new { Area = "" },
            constraints: new { HostConstraint = new MyConstraint() });

        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });

在这种情况下，MyConstraint 始终返回 true。

• 如果我尝试访问路线“/”，我最终会进入“管理”、“ Controller 主页”、“操作索引”区域。没关系。
• 如果我尝试访问“/rep”，那么我最终会进入根区域、 Controller 主页、操作索引。好的 。问题是这个 View 有一个链接引用我的 HomeController 中的另一个操作(来自根区域)。我期望链接指向/rep/home/action2 但生成的路由是/home/action2 。好像生成网址时存在一些错误匹配？

<a asp-action="Action">Action</a>

@Html.ActionLink("Action", "Action")

重新排序你的路线，先写admin-rep，然后写admin

app.UseMvc(routes =>
{


    routes.MapRoute(
        name: "admin-rep",
        template: "Rep/{controller=Home}/{action=Index}/{id?}",
        defaults: new { Area = "" },
        constraints: new { HostConstraint = new MyConstraint() });

    routes.MapRoute(
        name: "admin",
        template: "{controller=Home}/{action=Index}/{id?}",
        defaults: new {Area = "Admin"},
        constraints: new {HostConstraint = new MyConstraint()});

    routes.MapRoute(
        name: "default",
        template: "{controller=Home}/{action=Index}/{id?}");
});
