属性路由继承 [英] Attribute Routing Inheritance

问题描述

以前，我一直在MVC应用程序中使用过这种方法

I always used this approach in my MVC applications before

[Route("admin")]
public class AdminController : Controller
{

}

[Route("products")]
public class ProductsAdminController :AdminController
{ 
    [Route("list")]
    public IActionResult Index()
    {
        ...
    }
}

Url.RouteUrl()用于索引操作已返回/admin/products/list/

现在，在.NET Core中，它忽略了基类路由属性，结果仅为/products/list/ 这是.NET Core的新功能吗?有什么设置可以使系统结合 action + controller + base-controller 路由吗?

Now in .NET Core it ignores base class route attribute and result is just /products/list/ Is this new to .NET Core? Is there any setup so system can combine action + controller + base-controller routes?

推荐答案

我找不到自动组合 action + controller + base-controller 的方法，但是这样可以实现您想要的东西:

I can't find a way to combine action + controller + base-controller automatically, but it is possible to achieve what you're looking for like this:

[Route("admin")]
public class AdminController : Controller { }

public class ProductsAdminController : AdminController
{ 
    [Route("products/list")]
    public IActionResult Index()
    {
        ...
    }
}

此方法最终生成URL /admin/products/list，明显的缺点是products是每个操作都需要重复的内容.这可能是一个可以接受的折衷方案.由您决定.您可以使用常量使它更好地成为 bit ，例如:

This approach ends up generating a URL of /admin/products/list, with the obvious downside that products is something that needs to be repeated for each action. This might be an acceptable compromise; that's up to you to decide. You could make it a bit better with a constant, like this:

private const string RoutePrefix = "products";

[Route(RoutePrefix + "/list")]
public IActionResult Index()
{
    ...
}

这不是很好，因为它只是一种解决方法，但是如果您不想使用 Chris Pratt的Areas建议.

It's not pretty as it's just a workaround, but worth considering if you don't want to go with Chris Pratt's Areas suggestion.
