重命名Web API控制器已破坏POST路由

我有一个Web API控制器向Angular SPA提供数据,我决定重命名,使用VS 2015的重命名功能来更新我的所有引用。因此,我不能再发布它了(GET仍然有效),我在客户端上不断收到以下错误:

"A route named 'api/Trainees' could not be found in the route collection.
Parameter name: name"

此控制器以前使用默认路由工作正常 - RouteConfig.cs中没有任何内容,也没有属性路由,这使得它更加陌生。我假设ASP.NET仅根据控制器和方法名称计算出默认路由,或者它是否在任何地方缓存路由信息?

我的控制器看起来像这样:

public class TraineesController : ApiController
{
    private UserRepository repo = new UserRepository();

    // GET: api/Trainees
    public IEnumerable<Trainee> Get()
    {
        return this.repo.GetUsers();
    }

    // GET: api/Trainees/5
    public Trainee Get(string email)
    {
        if (!string.IsNullOrEmpty(email))
        {
            return this.repo.GetUser(email);
        }

        throw new ArgumentNullException("email");
    }

    // POST: api/Trainees
    public IHttpActionResult Post([FromBody]Trainee value)
    {
        try
        {
            this.repo.AddUser(value);
            return CreatedAtRoute("api/Trainees", value.Email, value);
        }
        catch (ArgumentOutOfRangeException)
        {
            return Conflict();
        }
    }

    // PUT: api/Trainees/5
    public IHttpActionResult Put([FromBody]Trainee value)
    {
        try
        {
            this.repo.UpdateUser(value);
            return StatusCode(HttpStatusCode.NoContent);
        }
        catch (ArgumentOutOfRangeException)
        {
            return NotFound();
        }
    }

    // DELETE: api/Trainees/5
    public IHttpActionResult Delete(string email)
    {
        try
        {
            this.repo.RemoveUser(email);
            return StatusCode(HttpStatusCode.NoContent);
        }
        catch (ArgumentOutOfRangeException)
        {
            return NotFound();
        }
    }
}

这是失败的请求(由Angular $资源生成):

Request:    POST /api/Trainees HTTP/1.1
Content-Type:   application/json;charset=utf-8

有点晚了,但这是因为您尝试将route template作为CreatedAtRoute

的第一个参数传递
return CreatedAtRoute("api/Trainees", value.Email, value);

您需要传递路线名称。您可以使用 RouteAttribute

命名您的路线
[Route("api/Trainees", Name="TraineesRoute")]`
