How to get an access_token from an address?

Question

Ruby on Rails

I use VKontakte authorization by sending the user to the following address
oauth.vk.com/authorize?client_id=xxxxx&redirect_uri=[REDIRECT_URI]&display=page&v=5.28&response_type=token , where REDIRECT_URI = localhost:3000/api/sessions/signin
After authorization, the contact redirects to the following address: localhost:3000/api/sessions/signin#access_token=xxxxxxx&expires_in=86400&user_id=xxxxxxx
How can I get an access_token from here in the controller?

Answer 1

You must change the response_type=token parameter to response_type=code in your request. After that, a request with the code parameter will come to the specified redirect_uri. Using this code, you can get an access_token by making a request from your server ("from the controller") to the VK server. Read more here .

What are you doing there?
First, a meaningless question on Facebook, now it's not better on VKontakte.

Answer 3

Instead of "Standalone/Mobile Apps", use "Third Party Sites and Widgets".
access_token from such a URL can only be obtained by an application that can create a browser window, i.e. mobile or desktop.
