无效的redirect_uri与'omniauth-facebook'gem

Question

So I went to this guide that explains how to start with omniauth. When I got to the end of step 4 to test the application at localhost:3000/auth/facebook, I got this error:

{ 
    "error": {
        "message": "Invalid redirect_uri: Given URL is not allowed by the application configuration.",
        "type": "OAuthException",
        "code": 191
    }
}  

I understand the problem is the URL in the Facebook developer center, but none of the solutions I read works for me...

(I know that there are some questions before regarding this issue, but I'm new to Ruby on Rails and need an explanation for dummies.)

Answer 1

Defining these settings at the Facebook developer center solved this for me:

• App Domain: (blank)

• Site URL: http://localhost:3000

Answer 2

选中网站选项，然后将网站URL设置为http://localhost:3000/ 。

Answer 3

If the Facebook user is being generated in your Ruby on Rails application as

http://localhost:3000/users/auth/facebook

you need configure the Facebook application (Website) under the App section to redirect to

http://localhost:3000/users/auth/facebook/callback

Answer 4

if you are in a production environment, something that i missed was just removing www. from the site url that you specify in the facebook app settings (settings > basic > Website with Facebook Login > site url).

so instead of http://www.website.com/ you should enter in http://website.com

this worked for me after a few hours of trying to figure out what was wrong and why i was getting this redirect erro.

Answer 5

If you already added a site url you must provide email and turn your app live, you can add email in settings -> basic -> contact email and then make your app live in APP REVIEW -> MAKE "you_app_name" PUBLIC? -> yes
