spring-auth-example

Demonstrates multiple authentication providers using spring security.

What is this example about?

This demo shows how to quickly setup an auth server of OAuth 2.0 using spring boot and spring-oauth-security.

It uses username/password authentication to exchange for a JWT Access Token / Refresh Token.

In addition, it demonstrates how to use client_id to differentiate two authentication providers that could verify username/password in completely different stores. This is useful when you want to use a same auth server for multiple user stores - perhaps different applications with isolated user systems.

How to run the demo?

simply start the server using following command

./gradlew bootRun

it will start the server on port 9090.

Request Access Token & Refresh Token

The example code hardcoded a user gan/foo for client_id foo_app, and dong/bar for client_id 'bar_app'; try curl the server using above combinations.

You should be able to see gan/foo can only be authenticated with client_id foo_app, and dong/bar can only be authenticated with client_id bar_app.

e.g.

curl -X POST -H "Authorization: Basic YmFyX2FwcDo=" -H "Content-Type: application/x-www-form-urlencoded" -d 'grant_type=password&username=dong&password=bar' "http://localhost:9090/oauth/token"

Note above Basic auth header Basic YmFyX2FwcDo= is encoded from client_id bar_app with empty password. In other words, it is Base64 encoded from string bar_app:, notice the trailing colon;

The response json would look like

Refresh tokens with Refresh Token

Request the server with a refresh_token, which is saved from above step, and grant type 'refresh_token', it will response with a pair of new access_token/refresh_token. E.g.

curl -X POST -H "Authorization: Basic YmFyX2FwcDo=" -H "Content-Type: application/x-www-form-urlencoded" -d 'grant_type=refresh_token&refresh_token=eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyX25hbWUiOiJkb25nIiwic2NvcGUiOlsiQkFSIl0sImF0aSI6Ijg5NGJkZWY2LWNmOTUtNDZhNi1iMTQwLTA5M2NkN2YwZWVlYiIsImV4cCI6MTQ4Nzg2ODA5MiwiYXV0aG9yaXRpZXMiOlsiQkFSX1JFQUQiLCJCQVJfV1JJVEUiXSwianRpIjoiNjczM2ZiMzItMzJkOS00ZjRlLWJhMDYtNzFmOTIzZDYwNDZmIiwiY2xpZW50X2lkIjoiYmFyX2FwcCJ9.pbnSeWQQ1XEZFrrpFEHd_BVFHh67XZv7TEajgHHL3oevKAOoWdq1iAxaXE5ImSbKAB2Z0NLUPy8HmCzZc2A5r853PGM_3MsRk2_ggdgKludTd9x8dZjs4eph1Vw6JM4x3K1KA72nodok7L0yMLUDiCiEMCr6lXVD5NLTelxW9ZcI7dZQhfGfA-ipdwbLTYFY2ZgQ7dYtaGtfgW1H7AYfo89l-AQHpCjE2MQiAsm_L5D1L41sKYM8lAcMAQ5X5YtXRYmLGGoET2wfdtC_0v57SqzgvojbzHOkOhd6tcr7WHI3RxZ9Kcnx_3Jc31JYLFxhCi7CtxT7ShzFt1UXQk9Eiw' "http://localhost:9090/oauth/token"
