oauth2

Allows your Martini application to support user login via an OAuth 2.0 backend. Requires sessions middleware. Google, Facebook, LinkedIn and Github sign-in are currently supported. Once endpoints are provided, this middleware can work with any OAuth 2.0 backend.

Usage

See example_test.go for a sample.

If a route requires login, you can add oauth2.LoginRequired to the handler chain. If user is not logged, they will be automatically redirected to the login path.

m.Get("/#-required", oauth2.LoginRequired, func() ...)

Auth flow

• /# will redirect user to the OAuth 2.0 provider's permissions dialog. If there is a next query param provided, user is redirected to the next page afterwards.
• If user agrees to connect, OAuth 2.0 provider will redirect to /oauth2callback to let your app to make the handshake. You need to register /oauth2callback as a Redirect URL in your application settings.
• /logout will log the user out. If there is a next query param provided, user is redirected to the next page afterwards.

You can customize the login, logout, oauth2callback and error paths:

oauth2.PathLogin = "/oauth2login"
oauth2.PathLogout = "/oauth2logout"
...
