Implementation of GameOn Auth project, using Spring Security.

See the application architecture description in the Game On! Docs for more information on how to use this service.

To build this project:

./gradlew build
docker build -t gameontext/gameon-auth auth-wlpcfg

Initial Urls:

• /auth/oauth2/authorization/dummy/facebook
• /auth/oauth2/authorization/dummy/github
• /auth/oauth2/authorization/dummy/google
• /auth/oauth2/authorization/dummy/dummy (only active during local development)

Redirect Urls: (for configuring within social apps, prefix the host/port of this app)

• /auth/oauth2/code/facebook
• /auth/oauth2/code/github
• /auth/oauth2/code/google

Addtional Urls:

• /auth/PublicCertificate serves pub cert for frontend use.

Old-Auth Compat urls:

• /auth/FacebookAuth
• /auth/GoogleAuth
• /auth/TwitterAuth
• /auth/GithubAuth
• /auth/DummyAuth

Browser goes to appropriate initial url, gets bounced to remote service to sign in, then back to redirect url, which reads tokens etc, and forwards browser to /auth/token endpoint.

/auth/token endpoint is a RestController, thats protected with Spring Security, requiring a successful authentication to have occurred before it can be invoked.

The appropriate information is then retrieved from the Spring Security authentication, and is used to build the JWT to return to the user.

Note: All urls need to start /auth to emulate the Old-Auth context root approach, otherwise GameOn Proxy would need updating to know how to route traffic to this service. As this is currently intended to be a drop in replacement, to enable A/B testing, canary deployment etc, it was better to keep urls compatible with Old-Auth. This also includes acutators which are moved to /auth in this project, eg /auth/health )

Note: Had to add a secondary domain name used to access the /auth/dummy endpoint because that's emulating an entirely different oauth2 server, we may yet revisit this idea, but that's how it sits for now.

Twitter isn't an OAuth2 provider, so the entire Twitter flow is handled by a TwitterController (RestController) that uses twitter4j to do the login, based on code from the old auth impl.
