使用Url.Link与属性中的WebAPI 2路由 [英] Using Url.Link with Attribute Routing in Webapi 2

问题描述

我想用的WebAPI 2.当下面的方法显示了如何使用命名的路由这样做是为了一个Location头添加到我的HTTP响应。有谁知道，如果你可以使用属性的路由功能，被释放的WebAPI 2的一部分创建Url.Link？

I want to add a Location header to my http response when using webapi 2. The method below shows how to do this using a named route. Does anyone know if you can create the Url.Link using Attribute Routing feature that was released as part of webapi 2?

string uri = Url.Link("DefaultApi", new { id = reponse.Id });
httpResponse.Headers.Location = new Uri(uri);

在此先感谢

推荐答案

您使用属性布线时可以使用RouteName与Ur.Link。

You can use RouteName with Ur.Link when using attribute routing.

public class BooksController : ApiController
{
    [Route("api/books/{id}", Name="GetBookById")]
    public BookDto GetBook(int id) 
    {
        // Implementation not shown...
    }

    [Route("api/books")]
    public HttpResponseMessage Post(Book book)
    {
        // Validate and add book to database (not shown)

        var response = Request.CreateResponse(HttpStatusCode.Created);

        // Generate a link to the new book and set the Location header in the response.
        string uri = Url.Link("GetBookById", new { id = book.BookId });
        response.Headers.Location = new Uri(uri);
        return response;
    }
}
