从路线名

Question

当路径被命名时......

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

...使用名称

创建绝对路径很容易

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

但是，我需要能够从Route名称生成相对路径。所以我写这样的代码：

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

以上是有效的，但在ASP.NET Core中，是否有更直接的方法来获得相同的结果？

上下文

为什么我需要这个？我制作的一些控制器实际上是通用的：

[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;
    }
}

我认为您正在寻找from itertools import imap with open("map.txt") as f: rows = imap(str.split, f) for row in rows: if row[0].startswith(".data."): a, b = row[0].rsplit(".", 1) print(next(rows)[0],a, b) 例如：

Url.RouteUrl
