尝试使用 WebApi 创建链接不起作用

Question

在我的项目中，我需要创建一个带参数的链接，所以我是这样做的：

var link = new Uri(Url.Link("GetUser", new { id = 1 }));

static List<Students> std = new List<Students>()
{
    new Students(){id = 1, Nome = "Nathiel"},
    new Students() {id = 2, Nome = "Barros"}
};

以及他们将接收 id 的方法：

[Route("{id:int}",Name = "GetUser")]
[HttpGet]
public async Task<HttpResponseMessage> Get(int id)
{
    var u = std.FirstOrDefault(x => x.id == id);

    var response = new HttpResponseMessage();
    response = Request.CreateResponse(HttpStatusCode.OK, u);

    var task = new TaskCompletionSource<HttpResponseMessage>();
    task.SetResult(response);
    return await task.Task;
}

问题是，URL 没有连接第二个路由“GetUser”，并且是这样的："http://localhost:52494/api/v1/Register/1"。

Answer 1

假设路由前缀是api/v1/Register

[RoutePrefix("api/v1/Register")]
public class RegisterController : ApiController {
    [HttpGet]
    [Route("{id:int}",Name = "GetUser")] //Matches GET api/v1/Register/1
    public async Task<IHttpActionResult> Get(int id) {
        //...code removed for brevity
    }
}

那是设计使然。

Route Name 用于标识生成路由时要使用的路由模板。

如果你想在 URL 中添加GetUser，则将其包含在路由模板中

[RoutePrefix("api/v1/Register")]
public class RegisterController : ApiController {
    [HttpGet]
    [Route("GetUser/{id:int}",Name = "GetUser")] //Matches GET api/v1/Register/GetUser/1
    public async Task<IHttpActionResult> Get(int id) {
        //...code removed for brevity
    }
}
