Where to set OAuth redirect_uri in an ASP.NET 4.5 web form application

Question

I cannot find anywhere how to set OAuth2 redirect_uri in an ASP.NET 4.5 webforms application. By default it is set to localhost and of course I get this error from google:

The redirect URI in the request: http://localhost:3884/signin-google did not match a registered redirect URI 

And this is from Facebook:

 Given URL is not allowed by the Application configuration.: One or more of the given URLs is not allowed by the App settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App domains. 

And I get this error from my site (not from the local host).

Answer 1

I tested the built-in external login logic for authentication, and I received this error even though my Google API credentials are correct. For example, the redirect URI was configured to:

http://localhost:29405/signin-google

It's strange that the default CallbackPath for Google Authentication is "/ signin-google", but I still had to set this to App_Start / Startup.Auth, so I added this line and it worked:

CallbackPath = new PathString ("/ signin-google")

So...

 app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions() { ClientId = "YOUR CLIENT ID", ClientSecret = "YOUR CLIENT SECRET", CallbackPath = new PathString("/signin-google") }); 

Answer 2

Having looked at the many answers, this is what worked for me:

• Enable Google + API

• The default redirect URI is / signin-google, so add it to your Authorized Redirect URI.

• Add this to your RouteConfig file:

  routes.MapRoute (name: "signin-google", url: "signin-google", defaults: new {controller = "Account", action = "ExternalLoginCallback"});

Hope this helps anyone who overcomes this problem.

Answer 3

You need to enable the Google+ API (it is not enabled by default).

Default CallbackPath ( /signin-google ) is fine, but you should add it to REDIRECT URIS in Credentials - OAuth ClientID (you can replace the default value /oauth2callback ).

You must also enable SSL ON.

I did what thenninger and Sanchitos published.

But only after I launched my webApp with SSL did it work.

You can enable SSL in the project properties here:

And make sure the application starts at the correct address:

I needed to add more path to the route, as shown below:

  routes.MapRoute(name: "signin-google", url: "localhost:44336/signin-google", defaults: new { controller = "Account", action = "ExternalLoginCallback" });
