我已经阅读了很多关于路由和控制器的问题,但我根本找不到我在找什么。我有这种结构的控制器:找到了与请求匹配的多个操作
更新:包括完整的源代码。
public class LocationsController : ApiController
{
private readonly IUnitOfWork _unitOfWork;
public LocationsController(IUnitOfWork unitOfWork)
{
_unitOfWork = unitOfWork;
}
// GET /api/locations/id
public Location Get(Guid id)
{
return this.QueryById<Location>(id, _unitOfWork);
}
// GET /api/locations
public IQueryable<Location> Get()
{
return this.Query<Location>(_unitOfWork);
}
// POST /api/locations
public HttpResponseMessage Post(Location location)
{
var id = _unitOfWork.CurrentSession.Save(location);
_unitOfWork.Commit();
var response = Request.CreateResponse<Location>(HttpStatusCode.Created, location);
response.Headers.Location = new Uri(Request.RequestUri, Url.Route(null, new { id }));
return response;
}
// PUT /api/locations
public Location Put(Location location)
{
var existingLocation = _unitOfWork.CurrentSession.Query<Location>().SingleOrDefault(x => x.Id == location.Id);
//check to ensure update can occur
if (existingLocation == null)
{
throw new HttpResponseException(HttpStatusCode.NotFound);
}
//merge detached entity into session
_unitOfWork.CurrentSession.Merge(location);
_unitOfWork.Commit();
return location;
}
// DELETE /api/locations/5
public HttpResponseMessage Delete(Guid id)
{
var existingLocation = _unitOfWork.CurrentSession.Query<Location>().SingleOrDefault(x => x.Id == id);
//check to ensure delete can occur
if (existingLocation != null)
{
_unitOfWork.CurrentSession.Delete(existingLocation);
_unitOfWork.Commit();
}
return new HttpResponseMessage(HttpStatusCode.NoContent);
}
// rpc/locations
public HttpResponseMessage Dummy()
{
// I use it to generate some random data to fill the database in a easy fashion
Location location = new Location();
location.Latitude = RandomData.Number.GetRandomDouble(-90, 90);
location.Longitude = RandomData.Number.GetRandomDouble(-180, 180);
location.Name = RandomData.LoremIpsum.GetSentence(4, false);
var id = _unitOfWork.CurrentSession.Save(location);
_unitOfWork.Commit();
var response = Request.CreateResponse<Location>(HttpStatusCode.Created, location);
response.Headers.Location = new Uri(Request.RequestUri, Url.Route(null, new { id }));
return response;
}
}
我的路线定义(Global.asax中):
public static void RegisterRoutes(RouteCollection routes)
{
// Default route
routes.MapHttpRoute(
name: "Default",
routeTemplate: "{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
// A route that enables RPC requests
routes.MapHttpRoute(
name: "RpcApi",
routeTemplate: "rpc/{controller}/{action}",
defaults: new { action = "Get" }
);
}
到目前为止,如果我打的浏览器:
[baseaddress]/locations/s0m3-gu1d-g0e5-hee5eeeee
//它的工作原理[baseaddress]/locations/
//找到多个结果[baseaddress]/rpc/locations/dummy
//它的工作原理
最奇怪的是,这曾经工作,直到我搞砸了我的NuGet在执行一些更新。我在这里错过了什么?
以GET,POST,PUT或delete开头的动词将自动映射到第一个路线,我的虚拟测试方法将通过rpc调用,这将落入第二个路线。
时引发的误差是InvalidOperationException
与消息
多个动作被发现匹配的要求,即:上式MYPROJECT System.Linq.IQueryable`1 [Myproject.Domain.Location]取得()。 Webservices.Controllers.LocationsController System.Net.Http.HttpResponseMessage假人()的类型Myproject.Webservices.Controllers.LocationsController
任何想法?
请您可以发布LocationsController的完整代码,包括修剪的RPC方法吗? – 2013-02-27 15:18:34

该项目建成并运行良好。我宁愿尝试修复并了解什么是错误的,而不是仅仅恢复。(我承认这种回复会让我回到几个小时)。 – Joel 2013-02-27 15:28:29
