Beego OAuth 2.0 Demo

A Beego example app to demo OAuth 2.0 using Google and Facebook.

The following are used in this example app:

• OAuth 2.0
  • oauth2
  • oauth2more
• Rendering
  • Bootstrap
  • Font Awesome
  • Social Buttons
  • Quicktemplate

Usage

App Hostname / OAuth 2.0 Redirect URI

Decide on the hostname for your app which will be used in the OAuth 2.0 URI.

The redirect URI is oauth2callback. For example, if your app URL is https://example.com, your redirect URI will be https://example.com/oauth2callback.

If you do not have an Internet accessible hostname, you can use ngrok for testing.
