如何定义到多个区域的端点路由 [英] How to define an endpoint route to multiple areas

问题描述

我正在尝试定义一个路由到多个区域的MapAreaControllerRoute().但是，在ASP.NET Core 3.0中，需要设置areaName:参数，因此将每个路由限制为一个区域.我不明白如何使用适用于多个区域的一个路线.

I am trying to define a MapAreaControllerRoute() that routes to multiple Areas. In ASP.NET Core 3.0, however, there is the areaName: parameter that needs to be set, thus restricting each route to a single area. I don't understand how I can use one route that will work for multiple Areas.

我已经阅读了Stack Overflow上的许多问题，但这似乎是ASP.NET Core 3.0中的新要求.在ASP.NET Core< = 2.2中，您可以创建MapRoute()而不定义集areaName.

I have read through many issues here on Stack Overflow, but it seems that this is a new requirement in ASP.NET Core 3.0. In ASP.NET Core <= 2.2 you could create a MapRoute() without defining a set areaName.

现在，在我的Startup.cs中，我将端点定义为:

As it is now, in my Startup.cs, I define my endpoints as:

app.UseEndpoints(endpoints =>
{
  endpoints.MapAreaControllerRoute(
    name: "Area1",
    areaName: "Area1",
    pattern: "{area:exists}/{controller=Home}/{action=Index}/{id?}"
  );

  endpoints.MapAreaControllerRoute(
    name: "Area2",
    areaName: "Area2",
    pattern: "{area:exists}/{controller=Home}/{action=Index}/{id?}"
  );

  endpoints.MapControllerRoute(
    name: "default",
    pattern: "{controller=Home}/{action=Index}/{id?}");

});

当然，必须有一种方法来定义一条覆盖所有区域的路线吗?

Surely, there must be a way to define a single route to cover all Areas?

推荐答案

好，因此，在阅读了更多的链接后，事实证明是区域控制器缺少属性的情况！ 通过使用以下标签标记控制器:

Ok, so after reading an additional bunch of links, it turns out to be a case of missing attributes for the area controllers! By tagging the controllers with the following tags:

[Area("Area1")]
[Route("Area1/[controller]/[action]")]
public class Area1Controller : Controller
{
    public IActionResult Index()
    {
        return View();
    }
}

并将路线更改为:

        app.UseEndpoints(endpoints =>
        {
                endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");

            endpoints.MapAreaControllerRoute(
                name: "areas",
                areaName: "areas",
                pattern: "{area}/{controller=Home}/{action=Index}/{id?}"
                );
    }

一切似乎都按预期进行.

everything seems to work as expected.
