Client Init - nov/rack-oauth2 GitHub Wiki

Minimum Setting

client = Rack::OAuth2::Client.new(
  identifier: YOUR_CLIENT_ID,
  secret: YOUR_CLIENT_SECRET,
  redirect_uri: YOUR_REDIRECT_URI,
  host: 'server.example.com'
)

rack-oauth2 uses /oauth2/authorize and /oauth2/token as default paths. In the above case, client uses

• https://server.example.com/oauth2/authorize as Authorization Endpoint
• https://server.example.com/oauth2/token as Token Endpoint

If your client is Public Client, then omit secret.

Customization

You can optionally specify authorization_endpoint and/or token_endpoint as absolute/relative URLs.

If the host component of authorization_endpoint and token_endpoint are different, you'll specify absolute URLs. In that case, you can omit host param.

client = Rack::OAuth2::Client.new(
  identifier: YOUR_CLIENT_ID,
  secret: YOUR_CLIENT_SECRET,
  redirect_uri: YOUR_REDIRECT_URI,
  authorization_endpoint: 'https://www.facebook.com/oauth/dialog',
  token_endpoint: 'https://graph.facebook.com/oauth/token'
)

If the host of 2 endpoints are same, but the path doesn't match rack-oauth2 default, you'll specify host and relative URLs.

client = Rack::OAuth2::Client.new(
  identifier: YOUR_CLIENT_ID,
  secret: YOUR_CLIENT_SECRET,
  redirect_uri: YOUR_REDIRECT_URI,
  host: 'github.com',
  authorization_endpoint: '/login/oauth/authorize',
  token_endpoint: '/login/oauth/access_token'
)
