I have the following area route registration method:
/// <summary>
/// Registers the area.
/// </summary>
/// <param name="context">The context.</param>
public override void RegisterArea(AreaRegistrationContext context)
{
// terminal customer url
context.MapRoute("TerminalCustomer", "Terminal/Customer/{action}/{id}", new { controller = MVCt4.TerminalArea.Customer.Name, action = MVCt4.TerminalArea.Customer.ActionNames.Index, id = string.Empty });
// terminal inbound pattern url
context.MapRoute("TerminalInboundPattern","Terminal/InboundPattern/{action}/{id}",new { controller = MVCt4.TerminalArea.InboundPattern.Name, action = MVCt4.TerminalArea.InboundPattern.ActionNames.Index, id = string.Empty });
// terminal outbound pattern url
context.MapRoute("TerminalOutboundPattern","Terminal/OutboundPattern/{action}/{id}",new { controller = MVCt4.TerminalArea.OutboundPattern.Name, action = MVCt4.TerminalArea.OutboundPattern.ActionNames.Index, id = string.Empty });
// terminal inbound shipment url
context.MapRoute("TerminalInboundShipment", "Terminal/InboundShipment/{action}/{id}", new { controller = MVCt4.TerminalArea.InboundShipment, action = MVCt4.TerminalArea.InboundShipment.ActionNames.Index, id = string.Empty });
// terminal outbound shipment url
context.MapRoute("TerminalOutboundShipment", "Terminal/OutboundShipment/{action}/{id}", new { controller = MVCt4.TerminalArea.OutboundShipment, action = MVCt4.TerminalArea.OutboundShipment.ActionNames.Index, id = string.Empty });
}
It works fine as is, but when I change to the typesafe and no magic way of like this:
context.MapRoute("TerminalOutboundShipment", "Terminal/OutboundShipment/{action}/{id}", MVCt4.TerminalArea.OutboundPattern.Index(), new {id = String.Empty});
I get a runtime error? I have this code in the global.asax file and it works fine:
static public void RegisterRoutes(RouteCollection routes)
{
// do not allow any body access our our resources
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.IgnoreRoute("favicon.ico");
// home url ok
routes.MapRoute("Default", "Home/{action}/{id}", MVCt4.Home.Index(), new {id = String.Empty});
}
In the areas it does not work put the main global asa it works fine?
I found a example on how to use the t4mvc on the code plex site.

I want my app to be a viewer and send target for PDFs but don't want it to create new instances everytime. How do I catch the view intent action in my MainActivity? I tried OnNewIntent() but it doesn't get called. Only if the app wasn't already running, I get the action in OnCreate(). What am I missing?
[Activity (Theme = "#style/MainTheme", Label = "MyPdfViewer", Icon = "#drawable/icon", /*MainLauncher = true, --> SplashActivity is now the MainLauncher */LaunchMode = LaunchMode.SingleTop, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
[IntentFilter(new[] { Intent.ActionSend }, Categories = new[] { Intent.CategoryDefault }, DataMimeType = #"application/pdf")]
[IntentFilter(new[] { Intent.ActionView }, Categories = new[] { Intent.CategoryDefault }, DataMimeType = #"application/pdf")]
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
{
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
LoadApplication (new App ());
// handle clipboard data "send to" or "view document" actions
if (Intent.Type == "application/pdf")
{
HandleSendOrViewAction();
}
}
protected virtual void OnNewIntent()
{
var data = this.Intent.Data; // <-- never called
// do similar thing like in HandleSendOrViewAction()
}
private bool HandleSendOrViewAction()
{
// Get the info from ClipData
var pdf = Intent.ClipData.GetItemAt(0);
// Open a stream from the URI
byte[] bytes;
Stream inputStream;
if (Intent.Action == Intent.ActionSend)
inputStream = ContentResolver.OpenInputStream(pdf.Uri);
else if (Intent.Action == Intent.ActionView)
inputStream = ContentResolver.OpenInputStream(Intent.Data);
else
return false;
using (StreamReader sr = new StreamReader(inputStream))
{
MemoryStream ms = new MemoryStream();
inputStream.CopyTo(ms);
bytes = ms.ToArray();
}
Services.PdfReceiver.Base64Data = Convert.ToBase64String(bytes);
return true;
}
but don't want it to create new instances everytime.
The standard and singleTop of Launch Mode would create multiple instances. if you do not want create instance every time, you could use singleTask and singleInstance instead.
For singleTop Launch Mode, you need to know, if an instance of the activity already exists at the top of the target task, the system routes the intent to that instance through a call to its onNewIntent() method, rather than creating a new instance of the activity. If the instance of the activity which already exists is not at the top, it would not call onNewIntent() method.
That's why i suggest to use singleTask. The system creates the activity at the root of a new task and routes the intent to it. However, if an instance of the activity already exists, the system routes the intent to existing instance through a call to its onNewIntent() method, rather than creating a new one.
Using SingleTop launch mode is correct. The reason that OnNewIntent() is not being called is that you have declared it like this:
protected virtual void OnNewIntent()
That isn't correct. The signature is wrong. You need to declare it like this:
protected override void OnNewIntent(Intent intent)
I have just implemented the Bearer token and I have added the Authorize attribute to my controller class and that works fine. It looks like this:
[Authorize(AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]
What I would like to do is to create a more complex response from the server when it fails, rather then the standard 401.
I tried filters but they are not invoked at all.
Any ideas how to do this?
Have a custom scheme, custom authorization handler and poof!
Notice that I injected the Handler in ConfigureServices:
services.AddAuthentication(options =>
{
options.DefaultScheme = ApiKeyAuthenticationOptions.DefaultScheme;
options.DefaultAuthenticateScheme = ApiKeyAuthenticationOptions.DefaultScheme;
})
.AddScheme<ApiKeyAuthenticationOptions, ApiKeyAuthenticationHandler>(
ApiKeyAuthenticationOptions.DefaultScheme, o => { });
ApiKeyAuthenticationOptions
public class ApiKeyAuthenticationOptions : AuthenticationSchemeOptions
{
public const string DefaultScheme = "API Key";
public string Scheme => DefaultScheme;
public string AuthenticationType = DefaultScheme;
public const string HeaderKey = "X-Api-Key";
}

var isValidToken = customRedisEvent.Exists(token, RedisDatabases.ApiKeyUser);
if (!isValidToken) {

var identity = new ClaimsIdentity (claims, nameof (ApiKeyAuthenticationHandler));

}
Focus on the handler class. Apart from the sample code I've provided, simply utilise the base class properties like Response to set your custom http status code or whatever you may need!
Here's the derived class if you need it.

Well, I am a new guy who is trying to develop a web application whose user are will be authenticated through Facebook. I am developing the application in MVC 4 .Net Framework. As it's internal programs are already done so I need not to do much coding. I have just put the API ID and Secret Key in the scope
OAuthWebSecurity.RegisterFacebookClient(
appId: "750397051803327",
appSecret: "**************************");
And here is my Application http://imgur.com/a/k4Vd0
My Application is taking properly the user permission from the user perfectly. http://imgur.com/a/bqzj5 but after taking permission it is not providing the login state of the user by showing such exception http://imgur.com/a/h81Oh login failed. I debugged form the code end and I observed that it is sending isLoggedin as false http://imgur.com/a/UuLIe therefore my I am not getting the access.
However 2 days before I am not getting such exception. I was getting data simply fine. Here is a snapshot of my previous data. http://imgur.com/a/Bc49F
I need that data again, but how? Is there anything need to change in my application dashboard? Possibly I have changed something in application dashboard. if yes then what is particularly that?
Another things I'm confused that what is the need for PRODUCTS? Do I need anything from the products for this special reason to get the data. If yes then which one shall I need and how to configure it to get back my previous systematic process in which I was getting data smoothly.
If I add App Center from the PRODUCTS I am obtaining two other secret keys like Account Kit App Secret and Account Kit Client Token Is that I need to use these keys for my requested case. For such login approval specific which Products are need or nothing need at all from PRODUCTS. I am so confused about it how to configure an application.
Please suggest me how to solve this problem in addition how to configure my application API. Thank you.
According to Previous Answer I got my solution. In MVC4 everyone write down their AppID and SecurityCode. Due to change of facebook GRAPH API those previous links are broken. Consequently everyone need to change the RegisterFacebookClient calss. But this class is a sealed class in the .Net library, so anyone can't extend or overwrite it. As a result we need to use a wrapper class. Let us consider my Wrapper class is FacebookClientV2Dot3 therefore my class will be

Look here you I have replaces all the API links by newer version links.
Now you need to modify your
AuthConfig
Just use a wrapper class
OAuthWebSecurity.RegisterClient(new FacebookClientV2Dot3("AppID", "HassedPassword"));
Then all success. You facebook login will be back in previous state.
However you can face a new issue regarding this new API rather than previous API, the problem is that IP Whitelisting. Like this image. Hope you will need nothing but this. Happy coding.
Yes!!!!
I got the solution of my own problem. According to Facebook developers bug report all Facebook log is not working from 28th March 2017. They also let us know through their developers Facebook group. The post link is here.
According to one of the Developer teams had said we're finding that
facebook authentication just stopped working (2pm EST) across multiple
apps that we manage. apps haven't changed, apps haven't been
suspended..... not sure where to report this since "status" is all
good......
This is a request for support for WP8 and Unity 5 for the Facebook SDK.
I am a developer wanting to produce games across many platforms, and being able to publish to the Windows Phone 8 store is a big part of my agenda.
Is support for this platform scheduled to be released any time soon? If so, when are you looking to release it?
Also, is there an imminent release for the Unity SDK that is designed to work with Unity 5? I have managed to get the current release to work, but as it is not yet fully supported, I do not know what will work and what won't.
Any information regarding these issues would be much appreciated!
Update: I ran into this video that explains how the "AndContinue" methods are going away in windows 10 so we can use one single method; the Async methods that already exists on windows 8/8.1 api. Check it out at https://youtu.be/aFVAP3fNJVo?t=23m34s
I was in the same place as you but managed to get it working. When I have time, ill probably write a blog on my experiences.
Here is some of the main code that directly calls on WebAuthenticationBroker:-
static bool isTryingToRegister { get; set; }
private static string _FbToken;
public static string response;
static bool isLoggedIn { get; set; }
static private string AppID { get { return "000000000000000000"; } }
static private Uri callback { get; set; }
static private string permissions { get { return "public_profile, user_friends, email, publish_actions, user_photos"; } }
public static System.Action<object> AuthSuccessCallback;
public static System.Action<object> AuthFailedCallback;
public static string fbToken
{
get
{
return _FbToken;
}
}
static Uri loginUrl
{
get
{
return new Uri(String.Format("https://www.facebook.com/v2.0/dialog/oauth/?client_id={0}&display=popup&response_type=token&redirect_uri={1}&scope={2}",
AppID,
callback,
permissions));
}
}
public static IEnumerator _Run_ConnectWithFacebook()
{
yield return new WaitForEndOfFrame();
#if UNITY_EDITOR
UnityDebugAuthentication();
#endif
#if NETFX_CORE
WindowsStoreAuthenticate();
#endif
}
#if NETFX_CORE
static void WindowsStoreAuthenticate()
{
#if UNITY_WP_8_1 && !UNITY_EDITOR
AuthSuccessCallback = _Run_ConnectWithFacebook_SuccessResponse;
AuthFailedCallback = _Run_ConnectWithFacebook_FailedResponse;
UnityEngine.WSA.Application.InvokeOnUIThread(
() =>
{
callback = WebAuthenticationBroker.GetCurrentApplicationCallbackUri();
WebAuthenticationBroker.AuthenticateAndContinue(loginUrl, callback, null, WebAuthenticationOptions.None);
}, true);
#endif
#if UNITY_METRO_8_1 && !UNITY_EDITOR
AuthSuccessCallback = _Run_ConnectWithFacebook_SuccessResponse;
AuthFailedCallback = _Run_ConnectWithFacebook_FailedResponse;

async () =>
{
callback = WebAuthenticationBroker.GetCurrentApplicationCallbackUri();
WebAuthenticationResult authResult = await WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.None, loginUrl);
}, true);
#endif
}
#endif
Note how I use WebAuthenticationBroker.AuthenticateAndContinue for windows phone and WebAuthenticationBroker.AuthenticateAsync for windows 8. This is necessary for their respective platforms. You may want to look into getting the WebAuthenticationBroker which is a Microsoft class that works on WP8 and WSA (im guessing you are aiming for WSA, so am I):-

You will also need to build a c# project in unity so you can implement part 2 of it which includes handling when the token details are returned to the app. Here is my code sample of App.xaml.cs which was inspired by https://msdn.microsoft.com/en-us/library/dn631755.aspx:-

You will also need the ContinuationManager.cs class and the SuspensionManager.cs class but mainly for WP8.1 Universal. This isnt needed for W8.1 and so you should ensure that you are using #defines to keep them within their own contexts
If you want, instead of calling on WebAuthenticationBroker, you could call on the facebook app directly but I don't know of all the details. You can read up on that on facebook's website developers.facebook.com/docs/facebook-login/login-for-windows-phone. That method isnt recommended incase the user doesn't have it installed.
Long (rushed) story short, call WebAuthenticationBroker, handle the continuation Event in OnActivated event to catch the WebAuthenticationBrokerContinuationEventArgs object coming through and use the data however you see fit. Be sure to use the following if you want to call any code in the unity side. Note that you can directly access the c# code from App.xaml.cs:-
AppCallbacks.Instance.InvokeOnAppThread(() =>
{
// back to Unity
//your code here
}, false);
Also note that this is mainly to get the access token. Once we have that, we can make basic WWW calls directly to facebook and get data back from it. The data will be returned as a JSON format (ps this is such an awesome clean format!) you can use the .NET json library to serialize it into a class. I use json2csharp.com to convert any example output into a class which I just parse into the json library.
In .Net MVC4 I'm using a subclassed AuthorizeAttribute to redirect all requests to the "Change Password" page when a user's password has been reset as follows:
public override void OnAuthorization(AuthorizationContext filterContext)
{
// Call base class method first
base.OnAuthorization(filterContext);
// Only redirect if password change is required and the requested action
// is not "Change Password"
if (!passwordChangeRequired
&& !(filterContext.Controller is ApplicantController &&
MVC.Applicant.ActionNames.ChangePassword.Equals(filterContext.ActionDescriptor.ActionName)))
{
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary
{
{ "controller", MVC.Applicant.Name },
{ "action", MVC.Applicant.ActionNames.ChangePassword }
});
}
}
Have just written this code it seems to work but am not yet confident and wondering if it could be simplified.
Especially regarding controllers and actions - the project is using T4MVC so do both need to be included separately in the check and redirect or could they somehow be combined?
Also should the base.OnAuthorization call be made at the start or end (or neither)?
Grateful for any pointers...
I ended up modifying this slightly to use ActionFilterAttribute instead of AuthorizeAttribute.
In case this is of use to anyone here is the code:
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)]
public class ChangePasswordAttribute : ActionFilterAttribute
{
/// <summary>
/// Filter on executing
/// </summary>
/// <param name="filterContext">The current action context</param>
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
if (filterContext == null)
{
throw new ArgumentNullException("filterContext");
}
// Don't redirect to "Change Password" action if it is the current action
if (filterContext.Controller is ApplicantController &&
MVC.Applicant.ActionNames.ChangePassword.Equals(filterContext.ActionDescriptor.ActionName))
{
return;
}
// Redirect if password change is required
if ((filterContext.HttpContext.Session[SessionKeys.PasswordChangeRequired] != null)
&& (bool)filterContext.HttpContext.Session[SessionKeys.PasswordChangeRequired])
{
// Save route in session so the user can be redirected appropriately after a successful password change
RouteValueDictionary routeValues = new RouteValueDictionary(filterContext.RouteData.Values);
filterContext.HttpContext.Session[SessionKeys.PasswordChangeRouteValues] = routeValues;
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary
{
{ "controller", MVC.Applicant.Name },
{ "action", MVC.Applicant.ActionNames.ChangePassword }
});
}
}
}
