從路由名稱獲取相對路徑

Question

當路徑被命名...

[Route("api/[controller]/{id}/Existing", Name = "ExistingOrdersLink")]
public class OrdersController : Controller {...}

...使用其名稱創建絕對路徑很容易：

var address = Url.Link("ExistingOrdersLink", new { id = 22 });

但是，我需要能夠從 Route 名稱生成相對路徑。 所以我寫了這樣的代碼：

//Is there a built-in mechanism for this?
string partial = new Uri(Url.Link("ExistingOrdersLink", new { id = id })).PathAndQuery;

以上工作，但在 ASP.NET Core 中，是否有更直接的方法來獲得相同的結果？

為什么我需要這個？ 我制作的一些控制器實際上是通用的：

[Route("api/Subscribers/{id}/[controller]", "SubscriberLink")]
[Route("api/Organization/{id}/[controller]", "OrganizationLink")]
public class OrdersController<T> : Controller where T : IOrder
{
    private ICommand<Order<T>> createOrder;

    protected OrdersController(ICommand<Order<T>> createOrder)
    {
        this.createOrder = createOrder;
    }

    [HttpPost("{otype}")]
    public async Task<IActionResult> Create(
        Guid id,
        [FromBody] Order<T> order)
    {
        order.CustomerOrderId = Guid.NewGuid();
        createOrder.Handle(order);

        string[] segs = Request.Path.Value.Split(new char[] { '/' },StringSplitOptions.RemoveEmptyEntries);

        //This will become either "SubscriberLink" or "OrganizationLink"
        string route = $"{segs[1]}Link";

        //Is there a built-in mechanism for this?
        string partial = new Uri(Url.Link(route, new { id = id })).PathAndQuery;

        partial = $"{partial}/{order.CustomerOrderId}";
        CreatedResult reply = Created(partial, null);

        return reply;
    }
}

我認為您正在尋找Url.RouteUrl示例：

Url.RouteUrl("ExistingOrdersLink", new { id = 22});
