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!";
}

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 }
);
}
So I have 2 controller:
[AllowCrossSiteJson]
public class ItemController : ApiController {
[HttpGet]
public LinkedList<Object> FindItem([FromUri]ItemQuery query) {
....
}
}
And
[AllowCrossSiteJson]
public class SubDepController : ApiController
{
[HttpGet]
public LinkedList<Object> FindSubDep(string ID) {
....
}
}
Here is the thing, I try to call both:
http://localhost:43751/api/SubDep
http://localhost:43751/api/Item
And the Item Controller works but the SubDep does not work! Why is that?
Here 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: "withAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
The error I get back is this:
{"Message":"No HTTP resource was found that matches the request URI 'http://localhost:43751/api/SubDep'.","MessageDetail":"No action was found on the controller 'SubDep' that matches the request."}
BONUS question:
How does ASP.NET MVC know that I try to hit:
http://localhost:43751/api/Item
It automatically go to the FindItem Action? It's like pure MAGIC to me!!
When you try to call FindSubDep action, your query string should be like belwo:
http://localhost:43751/api/SubDep/1
For the bonus question. It gets to the correct action because of the HTTP verb [GET] in your case, when you make a GET request for
http://localhost:43751/api/Item
it will find an action with [HttpGet] attribute on Item controller.
I'm fighting issues with routing in an MVC 3 Web API. It seems like it should be pretty simple, but I'm not making any headway.
My error is:
<Error>
<Message>The request is invalid.</Message>
<MessageDetail>
The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'Boolean NewViolationsPublished(Int32)' in 'BPA.API.Controllers.CacheManagementController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
</MessageDetail>
</Error>
My RegisterRoutes is such:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapHttpRoute(
name: "NukeAllItemsFromCache",
routeTemplate: "api/CacheManagement/NukeAllItemsFromCache");
routes.MapHttpRoute(
name: "ControllerAndAction",
routeTemplate: "api/{controller}/{action}"
);
routes.MapHttpRoute(
name: "ControllerAndActionAndId",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional, action = "Get" },
constraints: new { id = #"^\d+$" } // Only integers
);
routes.MapHttpRoute(
name: "ControllerAndId",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional },
constraints: new { id = #"^\d+$" } // Only integers
);
}
And my controller is (i took out the code for ease of reading):
public class CacheManagementController : ApiController
{
public CacheManagementController()
[HttpGet]
public bool NewViolationsPublished(int id)
[HttpGet]
public bool IsCached(CachedItemLabels label, int clientId)
[HttpGet]
public void RemoveItemFromCache(int clientId, CachedItemLabels cacheLabel, string test)
[HttpGet]
public string NukeAllItemsFromCache()
}
I get the error when I try to call:
http://localhost/api/CacheManagement/NukeAllItemsFromCache
TIA
Are you sure you're defining your routes in the right place? Web API routes should be configured using System.Web.Http.GlobalConfiguration.Configuration.Routes.MapHttpRoute (normally in a WebApiConfig.cs file in App_Start), as shown on http://www.asp.net/web-api/overview/extensibility/configuring-aspnet-web-api, which is different from the route configuration used by vanilla MVC.
I think you may just be hitting the default Web API route, which is api/{controller}/{id}, with ID optional. The action is determined by the HTTP verb, which in this case is GET, and all of your methods match that by virtue of the [HttpGet].
Edit: example
Global.asax
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
GlobalModifiers.ApplyGlobalConfiguration(this, true);
}
WebApiConfig.cs
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
config.Routes.MapHttpRoute(
name: "action-specific",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
I beleave your problem is in this route:
routes.MapHttpRoute(
name: "ControllerAndActionAndId",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional, action = "Get" },
constraints: new { id = #"^\d+$" } // Only integers
);
You specify id as an optional parameter and at the same time constrain it to actually be a non-nullable number. If /api/CacheManagement/NukeAllItemsFromCache is an exception, then add additional route for it, otherwise ease a constraint to something like #"^\d*$" if possible.
You are missing the default action for the route you configured:
routes.MapHttpRoute(
name: "NukeAllItemsFromCache",
routeTemplate: "api/CacheManagement/NukeAllItemsFromCache");
should be
routes.MapHttpRoute(
name: "NukeAllItemsFromCache",
routeTemplate: "api/CacheManagement/NukeAllItemsFromCache",
defaults: new { action = "NukeAllItemsFromCache" }
);
You tried to put parameter id as nullable like:
[HttpGet]
public bool NewViolationsPublished(int? id)
or
[HttpGet]
public bool NewViolationsPublished(Nullable<Int32> id)
Maybe this works...
Double check that your controller extends ApiController rather than Controller
public class CacheManagementController : ApiController
rather than
public class CacheManagementController : Controller
I have created a WebApi project, which has multiple WebApi controllers. As per my requirement I have to add an MVC controller to my WebApi project. My client side code is making an ajax request to that MVC controller with {ControllerName/ActionMethodName}. I have multiple routes in my global.asax file:
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
routes.MapHttpRoute(
name: "ActionRoute",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
Below is my ReportServiceBaseController:
protected virtual ReportServiceBase CreateReportService();
[HttpPost]
public JsonResult LoadDocumentInfo(LoadDocumentInfoRequest request);
[HttpPost]
public JsonResult LoadDocumentMapInfo(LoadDocumentMapInfoRequest request);
[HttpPost]
public JsonResult LoadDocumentMapInfoFull(LoadDocumentMapInfoFullRequest request);
[HttpPost]
public JsonResult LoadPageInfo(LoadPageInfoRequest request);
I am inheriting that controller in a ReportService controller:
public class ReportServiceController : ReportServiceBaseController
{
protected override PerpetuumSoft.Reporting.WebViewer.Server.ReportServiceBase CreateReportService()
{
return new ServiceClass();
}
}
The client side URL which is making the request:
"http://" + hostName + "/ReportService/LoadDocumentInfo"
I think the WebApi route is suppressing the MVC Controller route. How can I separate the MVC Controller route from the WebApi route?
You can create a new config class of WebApi, ApiRouteConfig.cs, within App_Start.
namespace Mvc4App
{
public class ApiRouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapHttpRoute(
name: "ActionRoute",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
}
Then, edit Global.asax.cs, to call ApiRouteConfig.RegisterRoutes(RouteTable.Routes);
I have a Controller called QuotaController, and i can access it via httprequests, like this:
localhost:12345/quota/
What i want is to put an endpoint somewhere so i can access it like:
localhost:12345/quota/increment
or
localhost:12345/quota/decrement
How can this be done?
You could change your web api route definition to allow passing an action name:
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
And then:
public class QuotaController : ApiController
{
public void Increment()
{
...
}
public void Decrement()
{
...
}
}
