OmniAuth VKontakte
This is the unofficial OmniAuth strategy for authenticating to VKontakte via OAuth. To use it, you'll need to sign up for an OAuth2 Application ID and Secret on the Vkontakte Developers Page.
Basic Usage
use OmniAuth::Builder do
provider :vkontakte, ENV['API_KEY'], ENV['API_SECRET']
end
Configuring
You can configure several options, which you pass in to the provider
method via a Hash
:
scope
: a comma-separated list of access permissions you want to request from the user. Read the Vkontakte docs for more detailsdisplay
: the display context to show the authentication page. Valid options includepage
,popup
andmobile
.lang
: specifies the language. Optional options includeru
,ua
,be
,en
,es
,fi
,de
,it
.image_size
: defines the size of the user's image. Valid options includemini
(50x50),bigger
(100x100),bigger_x2
(200x200),original
(200x*) andoriginal_x2
(400x*). Default ismini
.info_fields
: specify which fields should be added to AuthHash when getting the user's info. Value should be a comma-separated string as per http://vk.com/dev/fields.
Here's an example of a possible configuration:
use OmniAuth::Builder do
provider :vkontakte, ENV['API_KEY'], ENV['API_SECRET'],
{
:scope => 'friends,audio,photos',
:display => 'popup',
:lang => 'en',
:image_size => 'original'
}
end
