如何在 ASP.NET Core 中使用 Area?

How do I use an Area in ASP.NET Core?

我有一个需要管理部分的应用.此部分要求将其视图放置在该区域中.所有以 Admin/ 开头的请求都需要重定向到该区域.

I have an app that needs an Admin section. This section requires its Views to be placed in that area. All requests that start with Admin/ will need to be redirected to that area.

推荐答案

为了在 ASP.NET Core 应用程序中包含一个区域，首先我们需要在 Startup.cs 文件(最好放在任何非区域路由之前):

In order to include an Area in an ASP.NET Core app, first we need to include a conventional route in the Startup.cs file (It's best to place it before any non-area route):

在 Startup.cs/Configure 方法中:

In Startup.cs/Configure method:

app.UseMvc(routes =>
{
    routes.MapRoute("areaRoute", "{area:exists}/{controller=Admin}/{action=Index}/{id?}");

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

然后在应用根目录下创建一个名为Areas的文件夹，在前者里面再创建一个名为Admin的文件夹，同样在Admin内创建这些文件夹(ViewComponent 是可选的):

Then make a folder named Areas in the app root and make another named Admin inside the former, also make these folders inside Admin (ViewComponent is optional):

现在我们在Controllers文件夹中创建一个名为AdminController的控制器，内容可以是:

Now we create a controller inside the Controllers folder named AdminController, the content can be like:

[Area("Admin")]
[Route("admin")]
public class AdminController : Controller
{
    public AdminController()
    {
        // do stuff
    }

    public IActionResult Index()
    {
        return View();
    }

    [Route("[action]/{page:int?}")]
    public IActionResult Orders()
    {
        return View();
    }

    [Route("[action]")]
    public IActionResult Shop()
    {
        return View();
    }

    [Route("[action]/newest")]
    public IActionResult Payments()
    {
        return View();
    }
}

现在为了让它起作用，您需要为所有返回一个的操作创建视图.视图的层次结构就像您在非区域视图文件夹中所拥有的一样:

Now in order for that to work, you'll need to create Views for all actions that return one. The hierarchy for views is just like what you have in a non-area Views folder:

现在，您应该可以出发了！

Now, you should be good to go!

问题:如果我的区域内有另一个控制器怎么办?

Question: What if I what to have another controller inside my Area?

答案:

只需在 AdminController 旁边添加另一个控制器并确保路由如下所示:

Just add another controller beside AdminController and make sure the routes are like the following:

[Area("Admin")]
[Route("admin/[controller]")]
public class ProductsController : Controller
{
    public ProductsController()
    {
        //
    }

    [Route("{page:int?}")]
    public IActionResult Index()
    {
        return View();
    }
}

重要的部分是[Route("admin/[controller]")].这样你就可以保持路由到 admin/controller/action/...

The important part is [Route("admin/[controller]")]. With that you can keep the style of routing to admin/controller/action/...
