。NET Core 3.x中如何配置多个区域

Question

我的项目中有多个Areas。将项目形式从.NET Core 2.2升级到3.1后，这些区域将无法使用/调用。

我的控制器在Area内看起来像：-

[Area(nameof(CRM))]
[Authorize]
[ServiceFilter(typeof(ActionFilter))]
public class DefaultController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
}

以及用于处理多个区域的先前配置如下：-

   routes.MapRoute(name: "Area", template: "{area:exists}/{controller=Default}/{action=Index}/{id?}");
   routes.MapRoute(name: "Area Default Create", template: "{area:exists}/{controller=Default}/create", defaults: new { action = "CreateOrEdit" });
   routes.MapRoute(name: "Area Default Edit", template: "{area:exists}/{controller=Default}/edit/{id}", defaults: new { action = "CreateOrEdit" });

因为我们必须在.NET Core 3.1中使用UseEndpoints，所以用于处理多区域的新配置就像下面的[我尝试过的内容]

参考＃Endpoint Routing .net core 3-Multiple Areas和https://aregcode.com/blog/2019/dotnetcore-understanding-aspnet-endpoint-routing/

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

但是，它不起作用，也尝试通过以下方式致电，但未成功：-

endpoints.MapAreaControllerRoute(name: "Area", areaName: "areas", pattern: "{area:exists}/{controller=Default}/{action=Index}/{id?}");
endpoints.MapAreaControllerRoute(name: "Area Default Create", areaName: "areas", pattern: "{area:exists}/{controller=Default}/create", defaults: new { action = "CreateOrEdit" });
endpoints.MapAreaControllerRoute(name: "Area Default Edit", areaName: "areas", pattern: "{area:exists}/{controller=Default}/edit/{id}", defaults: new { action = "CreateOrEdit" });

即使它也不适用于单个区域

参考＃https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-3.1&tabs=visual-studio

endpoints.MapAreaControllerRoute(name: "Area", areaName: "CRM", pattern: "CRM/{controller=Default}/{action=Index}/{id?}");

Answer 1

我只是自己解决问题，这是克服这种情况的解决方案：-

在Startup.cs类中，添加以下行以处理多个Areas >>]的动态路由

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

这里areas

是Areas文件夹的名称[默认]。您可以根据需要更改它。

如下更改控制器的标题标记：-

[Area(nameof(CRM))]  // CRM is the another-folder name inside Areas folder
[Route("CRM/[controller]/[action]")]
[Authorize]
[ServiceFilter(typeof(ActionFilter))]
public class DefaultController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
}
最后更改如下所示的Razor标记，以在Areas Controllers文件夹内调用目标Action
<a asp-area="CRM" asp-controller="Default" asp-action="Index">Home of CRM</a>
