I cannot get the HttpContext.Current.GetOwinContext().Authentication.Challenge to work extending a ApiController it just doesnt do anything, not even an error. I just get the output ":("
What am i doing wrong can this even be achieved? this is a Web API and the Controller RegisterRoutes is causing problems with my custom routes
It works fine when I extend Controller
public class AccountController : Controller
{
public void SignIn()
{
// Send an OpenID Connect sign-in request.
if (!Request.IsAuthenticated)
{
HttpContext.GetOwinContext().Authentication.Challenge(new AuthenticationProperties { RedirectUri = "/" }, OpenIdConnectAuthenticationDefaults.AuthenticationType);
}
}
}
It does not work when i extend ApiController
[RoutePrefix("api/auth")]
public class AuthController : ApiController
{
[HttpGet, Route("signin")]
public IHttpActionResult SignIn()
{
if (User == null || User.Identity.IsAuthenticated == false)
{
HttpContext.Current.GetOwinContext().Authentication
.Challenge(new AuthenticationProperties() {RedirectUri = "/"}, OpenIdConnectAuthenticationDefaults.AuthenticationType);
return Ok(":(");
}
return Ok(":)");
}
}
This wont allow my ApiController routing to work
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new {controller = "Home", action = "Index", id = UrlParameter.Optional}
);
}

I am clearly having issue understanding the routes here or trying to achieve which is not possible.
I have this in my RouteConfig:
routes.MapRoute(
name: "Explorer",
url: "{controller}/{action}/{prefix}/{value}",
defaults: new { controller = "Explorer", action = "Index", prefix ="", value = UrlParameter.Optional }
);
And in Explorer Controller I have the following:
[RoutePrefix("Explorer")]
public class ExplorerController : Controller
{
public ActionResult Index()
{
return View();
}
[Route("id/{value}")]
public ActionResult Import(decimal? importId)
{
return View();
}
[Route("text/{value}")]
public ActionResult Import(string importWindow)
{
return View();
}
}
One of the ACTION (Import) has different PREFIX such as window and id but whenever I try to access it (such as https://localhost/Explorer/Import/window/helloWorld OR https://localhost/Explorer/Import/id/200) it keeps giving me the following error
The current request for action 'Import' on controller type
'ExplorerController' is ambiguous between the following action
methods: System.Web.Mvc.ActionResult
Import(System.Nullable`1[System.Decimal]) on type
projectname.Controllers.ExplorerController System.Web.Mvc.ActionResult
Import(System.String) on type projectname.Controllers.ExplorerController
I know it is ambiguous but I have a prefix which should make it non-ambiguous.
What am I doing wrong here and how to achieve this outcome if this is not the right way to do it?
Apply the [Route()] attribute for action methods in the controller class:
[RoutePrefix("Explorer")]
public class ExplorerController : Controller
{
// GET: Explorer
public ActionResult Index()
{
return View();
}
// Example: https://localhost/Explorer/Import/id/200
[Route("Import/id/{importId:decimal}")]
public ActionResult Import(decimal? importId)
{
return View();
}
// Example: https://localhost/Explorer/Import/window/helloWorld
[Route("Import/{text}/{importWindow}")]
public ActionResult Import(string importWindow)
{
return View();
}
}
Define only the Default route in the RegisterRoutes() method:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes();
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
I have overridden a default route in my routes configuration :
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapRoute("MyController_OverriddenAction",
"MyController/OverriddenAction",
new { controller = "MyOverriddenController", action = "OverridenAction" },
new[] { "Plugin" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "home", action = "Index", id = UrlParameter.Optional }
);
}
}
If I call MyController/OverriddenAction, the overridden action OverriddenAction in MyOverriddenController is displayed. It works.
But if I call #Html.Action("OverriddenAction", "MyController"), the default route is called.
Why? What is the solution?
My controllers :
public class MyOverridenController : Controller
{
public ActionResult OverriddenAction()
{
return Content("overridden");
}
}
public class MyController : Controller
{
public ActionResult OverriddenAction()
{
return new EmptyResult();
}
[...]
}
You should use following syntax
#Html.Action("OverriddenAction", "MyOverriden")
while calling the method directly like MyController/OverriddenAction it looks for the entry in MapRoute. However, while using #Html.Action you should use the actual controller name.
I would like to be able to create a succinct language-specific default URL for my website so that when someone browses to:
somesite.com
They get redirected to a language-culture page such as:
somesite.com/en-US/
somesite.com/sp-MX/
somesite.com/fr-FR/
Specifically, I do not want /Home/Index appended to the URLs:
somesite.com/en-US/Home/Index
somesite.com/sp-MX/Home/Index
somesite.com/fr-FR/Home/Index
I am committed to making this site using RouteLocalization.mvc
Dresel/RouteLocalization
Translating Your ASP.NET MVC Routes
And I would like to use MVC Attribute Routing to the extent feasible.
I am having trouble figuring out how to cause the Start() method redirect to a language-culture specific URL without the addition of something like "index".
Samples of what I have attempted follow:
using RouteLocalization.Mvc;
using RouteLocalization.Mvc.Extensions;
using RouteLocalization.Mvc.Setup;
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.Clear();
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapMvcAttributeRoutes(Localization.LocalizationDirectRouteProvider);
const string en = "en-us";
ISet<string> acceptedCultures = new HashSet<string>() { en, "de", "fr", "es", "it" };
routes.Localization(configuration =>
{
configuration.DefaultCulture = en;
configuration.AcceptedCultures = acceptedCultures;
configuration.AttributeRouteProcessing = AttributeRouteProcessing.AddAsNeutralAndDefaultCultureRoute;
configuration.AddCultureAsRoutePrefix = true;
configuration.AddTranslationToSimiliarUrls = true;
}).TranslateInitialAttributeRoutes().Translate(localization =>
{
localization.AddRoutesTranslation();
});
CultureSensitiveHttpModule.GetCultureFromHttpContextDelegate = Localization.DetectCultureFromBrowserUserLanguages(acceptedCultures, en);
var defaultCulture = System.Threading.Thread.CurrentThread.CurrentUICulture.Name;
routes.MapRoute(
name: "DefaultLocalized",
url: "{culture}/{controller}/{action}/{id}",
constraints: new { culture = #"(\w{2})|(\w{2}-\w{2})" },
defaults: new { culture = defaultCulture, controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
And my home controller:
public class HomeController : Controller
{
[HttpGet]
[Route]
public RedirectToRouteResult Start()
{
return RedirectToAction("Home", new { culture = Thread.CurrentThread.CurrentCulture.Name });
}
[Route("Index", Name = "Home.Index")]
public ActionResult Index()
{
return View();
}
public ActionResult Contact()
{
return View();
}
public ActionResult About()
{
return View();
}
}
My Global.asax file:
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
AreaRegistration.RegisterAllAreas();
}
}
Redirecting is a separate concern than routing. Since your goal of redirecting any URL to its localized counterpart is a cross-cutting concern your best bet is to make a global filter.
public class RedirectToUserLanguageFilter : IActionFilter
{
private readonly string defaultCulture;
private readonly IEnumerable<string> supportedCultures;
public RedirectToUserLanguageFilter(string defaultCulture, IEnumerable<string> supportedCultures)
{
if (string.IsNullOrEmpty(defaultCulture))
throw new ArgumentNullException("defaultCulture");
if (supportedCultures == null || !supportedCultures.Any())
throw new ArgumentNullException("supportedCultures");
this.defaultCulture = defaultCulture;
this.supportedCultures = supportedCultures;
}
public void OnActionExecuting(ActionExecutingContext filterContext)
{
var routeValues = filterContext.RequestContext.RouteData.Values;
// If there is no value for culture, redirect
if (routeValues != null && !routeValues.ContainsKey("culture"))
{
string culture = this.defaultCulture;
var userLanguages = filterContext.HttpContext.Request.UserLanguages;
if (userLanguages.Length > 0)
{
foreach (string language in userLanguages.SelectMany(x => x.Split(';')))
{
// Check whether language is supported before setting it.
if (supportedCultures.Contains(language))
{
culture = language;
break;
}
}
}
// Add the culture to the route values
routeValues.Add("culture", culture);
filterContext.Result = new RedirectToRouteResult(routeValues);
}
}
public void OnActionExecuted(ActionExecutedContext filterContext)
{
// Do nothing
}
}
Usage
public class FilterConfig
{
public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
filters.Add(new RedirectToUserLanguageFilter("en", new string[] { "en", "de", "fr", "es", "it" }));
filters.Add(new HandleErrorAttribute());
}
}
Note also that your routing is misconfigured. The route setup is run one time per application startup, so setting the default culture to that of the current thread is meaningless. In fact, you should not be setting a default culture at all for your culture route because you want it to miss so your Default route will execute if there is no culture set.
routes.MapRoute(
name: "DefaultLocalized",
url: "{culture}/{controller}/{action}/{id}",
constraints: new { culture = #"(\w{2})|(\w{2}-\w{2})" },
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
I am working on an ASP.NET MVC app. I am trying to create a basic API. I created my first Web API controller by right-clicking on Controllers, Add -> Controller... then choosing "Web API 2 Controller - Empty". In the controller code, I have the following:
namespace MyProject.Controllers
{
public class MyApiController : ApiController
{
public IHttpActionResult Get()
{
var results = new[]
{
new { ResultId = 1, ResultName = "Bill" },
new { ResultId = 2, ResultName = "Ted" }
};
return Ok(results);
}
}
}
When I run the app, I enter http://localhost:61549/api/myApi in the browser's address bar. Unfortunately, I get a 404. I'm just trying to create an API endpoint that returns a hard-coded set of JSON objects. I need this to test some client-side JavaScript. What am I doing wrong?
Here are how my routes are registered:
WebApiConfig.cs
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
RouteConfig.cs
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
Make sure that you have the WebApiConfig registration being called, possibly in the Global.asax Application_Start() method. Something like:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
You did not add method name at the end of call. Try this one:
http://localhost:61549/api/myapi/get
Try this approach
namespace MyProject.Controllers
{
public class MyApiController : ApiController
{
public IHttpActionResult Get()
{
var results = new List<ResultModel>
{
new ResultModel() {ResultId = 1, ResultName = "Bill"},
new ResultModel() {ResultId = 2, ResultName = "Ted"}
};
return Ok(results);
}
}
public class ResultModel
{
public int ResultId { get; set; }
public string ResultName { get; set; }
}
}
Api: http://localhost:61549/api/MyApi/get
Hope this helps.
Hy there,
I need to enforce Lowercase routes in my Web API project.
If it was an MVC project i would use something like
routes.LowercaseUrls = true;
But in Web API that property does not exists.
I tried the LowercaseRoutesMVC4 NuGet extension but my routes needs to have a custom handler so that extension does not help me.
What can I do?
This looks like it does what you need
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional },
constraints: new { url = new LowercaseRouteConstraint() }
);
}
}
public class LowercaseRouteConstraint : IRouteConstraint
{
public bool Match(HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values, RouteDirection routeDirection)
{
var path = httpContext.Request.Url.AbsolutePath;
return path.Equals(path.ToLowerInvariant(), StringComparison.InvariantCulture);
}
}
I found this at https://gist.github.com/benfoster/3274578#file-gistfile1-cs-L4
I have json config like
public class JsonConfig
{
public static void Initiliaze(HttpConfiguration config, bool isCamelCase)
{
var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = PreserveReferencesHandling.None;
json.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
json.SerializerSettings.Formatting = Formatting.None;
if (isCamelCase)
json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
config.Formatters.Remove(config.Formatters.XmlFormatter);
}
}
You can call this method in WebApiConfig.cs like
JsonConfig.Initiliaze(config, true);
