@RequestMapping("/vrspace/api/oauth2")
public class Oauth2Login
extends ApiBase

Oauth2 login is completely handled by spring security, this is just callback once it's all done. Client's identity is something like joe:facebook, but hashed. Login name must match the stored identity. After login, user's Client object is stored in HttpSession, under key specified by clientFactory.clientAttribute() (local-user-name by default).

 org.springframework.security.oauth2.client.registration.ClientRegistrationRepository clientRegistrationRepository)

Method Details

providers

@GetMapping("/providers")
public Map<String,String> providers()

List of OAuth2 registered authentication providers.

key-value pair of id and name, as declared in application.properties

setProvider

@GetMapping("/provider")
public org.springframework.http.ResponseEntity<String> setProvider(jakarta.servlet.http.HttpSession session,
 jakarta.servlet.http.HttpServletRequest request)

First step in Oauth2 Authentication is to obtain valid authentication provider id. This is never called directly though, the browser is redirected here from the login page. Obtains the provider id from the original request and sends browser redirect.

afterAuthentication

@GetMapping("/login")
public org.springframework.http.ResponseEntity<String> afterAuthentication(String name,
 String provider,
 String avatar,
 jakarta.servlet.http.HttpSession session,
 jakarta.servlet.http.HttpServletRequest request)

This endpoint requires both user name and authentication provider id (fb, github, google... as defined in app properties file). The framework then performs authentication through a series of on-site and off-site redirects. Only after successful Oauth2 authentication with external provider, the browser lands here. This method fetches or creates the Client object, and redirect back to the referring page. Client object is stored in HttpSession, under key specified by clientFactory.clientAttribute().

Parameters:

name - Login name of the user, local

provider - Oauth2 authentication provider id , as registered in properties file (e.g. github, facebook, google)

avatar - Optional avatar URI, used only when creating a new user
