No HTTP resource was found that matches the request URI :( - asp.net-mvc

This is my webApiConfig
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional });
config.Routes.MapHttpRoute(
name: "ApiByActionWithid",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { action = "" },
constraints: new { id = #"^[0-9]+$" });
config.Routes.MapHttpRoute(
name: "ApiByAction",
routeTemplate: "api/{controller}/{action}",
defaults: new { action = "" });
The changeOrderState action looks like this:
public ResponseDTO ChangeOrderState(Int32 changeOrderState, string state)
{
IRestaurantManager rm = Core.CoreManager.Instance.GetService<IRestaurantManager>();
return rm.ChangeOrderState(changeOrderState, state);
}
And I call a method like this:
https://localhost:44302/api/Restaurant?changeOrderState=1&state=Rechazado
But it doesn't work, but in others calls that the same way do work

i solved this, the answer is add the next in te method [HttpGet] and my action looks like this:
[HttpGet]
public ResponseDTO ChangeOrderState(int changeOrderState, string state="")
{
IRestaurantManager rm = Core.CoreManager.Instance.GetService<IRestaurantManager>();
return rm.ChangeOrderState(changeOrderState, state);
}

web api not working in sub folder

My web API is working well but when i write same code in area folder it not working.
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "FeatureA",
routeTemplate: "FeatureA/api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
You need to put your routing details in the "YourHubNameAreaRegistration" class that's in your Area folder. It goes in the RegisterArea method and should look something like this:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Hub_default",
"api/Hub/{action}/{id}",
new { controller = "Hub", action = "Index", id = UrlParameter.Optional }
);
}

404 when calling Web API v2

I have a Web Api controller which returns 404 when I call it.
public class ValuesController : ApiController
{
[HttpGet]
public static string Test()
{
return "Hola!";
}
}
Heres the Route Config
config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
And here's the Route Debugger info.
I get 404 for below requests
http://localhost:8081/api/values/test
http://localhost:8081/api/values/get
Any ideas why its failing?
Your action is defined as a static method. Actions cannot be static.
[HttpGet]
public static string Test()
{
return "Hola!";
}
Make it an instance method and your code will work.
[HttpGet]
public string Test()
{
return "Hola!";
}

ASP.NET MVC simplify routing

How can I simplify these routes?
config.Routes.MapHttpRoute(
name: "GetUsersRoute",
routeTemplate: "api/User",
defaults: new { controller = "User", action = "GetUsers" }
);
config.Routes.MapHttpRoute(
name: "GetUserRoute",
routeTemplate: "api/User/{id}",
defaults: new { controller = "User", action = "GetUser", id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "GetEmailAddressRoute",
routeTemplate: "api/User/GetEmailAddress/{id}",
defaults: new { controller = "User", action="GetEmailAddress", id = RouteParameter.Optional }
);
/*** Default ***/
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
I needed to add the GetEmailAddressRoute because the controller didn't know which action to take for a path like api/User/5. However, since then former routes like api/User don't lead to the correct action.
Some action signatures from the controller:
public Object GetUsers() { };
public Object GetUser(int id) { };
public HttpResponseMessage GetEmailAddress (int id) { };
But now I'd need to add another route for the Post actions. Is there a simpler way?
Update: What helped me for posting new users was to remove the action from the first route. Now it is
config.Routes.MapHttpRoute(
name: "GetUsersRoute",
routeTemplate: "api/User",
defaults: new { controller = "User" }
);
You can take advantage of the new routing attribute feature coming with web api 2 :
[Route("api/User")]
public Object GetUsers() { };
[Route("api/User/{id}")]
public Object GetUser(int id) { };
[Route("api/User/GetEmailAddress/{id}")]
public HttpResponseMessage GetEmailAddress (int id) { };

MVC API Routing When Multiple Get Actions Are Present

There seems to be a thousand people asking the same question on stack overflow, but there doesn't seem to be a single solution to this problem. I am going to ask it again...
I have an API controller that has the following actions:
// GET api/Exploitation
public HttpResponseMessage Get() {
var items = _exploitationRepository.FindAll();
var mappedItems = Mapper.Map<IEnumerable<Exploitation>, IEnumerable<ExploitationView>>(items);
var response = Request.CreateResponse<IEnumerable<ExploitationView>>(HttpStatusCode.OK, mappedItems);
response.Headers.Location = new Uri(Url.Link("DefaultApi", new { }));
return response;
}
// GET api/Exploitation/5
[HttpGet, ActionName("Get")]
public HttpResponseMessage Get(int id) {
var item = _exploitationRepository.FindById(id);
var mappedItem = Mapper.Map<Exploitation, ExploitationView>(item);
var response = Request.CreateResponse<ExploitationView>(HttpStatusCode.OK, mappedItem);
response.Headers.Location = new Uri(Url.Link("DefaultApi", new { id = id }));
return response;
}
// GET api/Exploitation/GetBySongwriterId/5
[HttpGet, ActionName("GetBySongwriterId")]
public HttpResponseMessage GetBySongwriterId(int id) {
var item = _exploitationRepository.Find(e => e.Song.SongWriterSongs.Any(s => s.SongWriterId == id))
.OrderByDescending(e => e.ReleaseDate);
var mappedItem = Mapper.Map<IEnumerable<Exploitation>, IEnumerable<ExploitationView>>(item);
var response = Request.CreateResponse<IEnumerable<ExploitationView>>(HttpStatusCode.OK, mappedItem);
response.Headers.Location = new Uri(Url.Link("DefaultApi", new { id = id }));
return response;
}
// GET api/Exploitation/GetBySongwriterId/5
[HttpGet, ActionName("GetBySongId")]
public HttpResponseMessage GetBySongId(int id) {
var item = _exploitationRepository.Find(e => e.SongId == id)
.OrderByDescending(e => e.ReleaseDate);
var mappedItem = Mapper.Map<IEnumerable<Exploitation>, IEnumerable<ExploitationView>>(item);
var response = Request.CreateResponse<IEnumerable<ExploitationView>>(HttpStatusCode.OK, mappedItem);
response.Headers.Location = new Uri(Url.Link("DefaultApi", new { id = id }));
return response;
}
In my APIConfig I have defined the following routes:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional, action = RouteParameter.Optional },
constraints: new { id = #"\d+" }
);
I am finding that I can access the following actions no problem:
/api/exploitation
/api/exploitation/getbysongwriterid/1
/api/exploitation/getbysongid/1
When I try to access /api/exploitation/1 I get this exception
"Multiple actions were found that match the request: System.Net.Http.HttpResponseMessage Get(Int32) on type Songistry.API.ExploitationController System.Net.Http.HttpResponseMessage GetBySongwriterId(Int32)" exception.
Can anyone see what is wrong with my routes? Or wrong with something else?
I have found an elegant solution to the problem.
I modified my ApiRouteConfig to have the following routes:
config.Routes.MapHttpRoute(
name: "DefaultGetApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional, action = "Get" },
constraints: new { id = #"\d+", httpMethod = new HttpMethodConstraint(HttpMethod.Get) }
);
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional },
constraints: new { id = #"\d+" }
);
config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional, action = RouteParameter.Optional }
);
Now I can access:
/api/exploitation
/api/exploitation/1
/api/exploitation/getbysongid/1
/api/exploitation/getbysongwriterid/1
I did not need to modify my controller actions to work with this new routing config at all.
If you had multiple PUT or POST actions you could the create new routes that looked as follows:
config.Routes.MapHttpRoute(
name: "DefaultGetApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional, action = "Put" },
constraints: new { id = #"\d+", httpMethod = new HttpMethodConstraint(HttpMethod.Put) }
);
config.Routes.MapHttpRoute(
name: "DefaultGetApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional, action = "Delete" },
constraints: new { id = #"\d+", httpMethod = new HttpMethodConstraint(HttpMethod.Delete) }
);
I hope that this answer helps everyone as this seems to be a common issue that people are having.
The problem you have is that /api/exploitation/1 falls under:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
All of your GET methods satisfy that routing as well particularly because {id} is optional and their controller is the same.
So you have one HTTP GET request from the client and multiple methods that accept GET requests. It doesn't know which one to go to.
api/{controller}/{action}/{id}
//This works fine because you specified which action explicitly
I hope that answers your question.
Try the following in your route definition. Keep only the following route:
config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional, action = "Get" },
constraints: new { id = #"\d+" }
);
Make the first Get method private, modify the second one so that id has a default value:
// GET api/Exploitation
private HttpResponseMessage Get() {
// implementation stays the same but now it's private
}
// GET api/Exploitation/5
[HttpGet, ActionName("Get")]
public HttpResponseMessage Get(int id = 0) {
if (id == 0) {
return Get();
}
// continue standard implementation
}
This way (I haven't tested it myself) I expect that:
api/Exploitation/ will map to api/Exploitation/Get(as default action) with id = 0 as default param
api/Exploitation/1 will map to api/Exploitation/Get/1 so it will call Get(1)
api/Exploitation/someOtherAction/345 will call the correct action method
This might work. A tighter route definition could actually be like this:
config.Routes.MapHttpRoute(
name: "ApiWithRequiredId",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: null /* make sure we have explicit action and id */,
constraints: new { id = #"\d+" }
);
config.Routes.MapHttpRoute(
name: "ApiWithOptionalId",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional, action = "Get" },
constraints: new { action = "Get" /* only allow Get method to work with an optional id */, id = #"\d+" }
);
But something along these lines... give it a try I hope it solves your problem.

Routing in Asp.net Mvc 4 and Web Api

Can I use the following two route rule together ?
config.Routes.MapHttpRoute(
name: "ActionApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional } );
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
Say by controller is = FruitApiController:ApiController and I wish to have the following
List<Fruit> Get() = api/FruitApi/
List<Fruit> GetSeasonalFruits() = api/FruitApi/GetSeasonalFruit
Fruit GetFruits(string id) = api/FruitApi/15
Fruit GetFruitsByName(string name) = api/FruitApi/GetFruitsByName/apple
Please help me on this. Thanks
You could have a couple of routes:
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "ApiById",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional },
constraints: new { id = #"^[0-9]+$" }
);
config.Routes.MapHttpRoute(
name: "ApiByName",
routeTemplate: "api/{controller}/{action}/{name}",
defaults: null,
constraints: new { name = #"^[a-z]+$" }
);
config.Routes.MapHttpRoute(
name: "ApiByAction",
routeTemplate: "api/{controller}/{action}",
defaults: new { action = "Get" }
);
}
}
config.Routes.MapHttpRoute(
name: "ApiByName",
routeTemplate: "api/{controller}/{action}/{name}",
defaults: null,
constraints: new { name = #"^[a-z]+$" }
);
