Create client

http POST http://localhost:8080/clients clientId=client clientSecret=secret scope=write

grant_type=password

To get an access token:

curl -v -XPOST -u client:secret "http://localhost:8080/oauth/token?grant_type=password&username=john&password=12345&scope=read"
http -a client:secret POST localhost:8080/oauth/token grant_type==password username==john password==12345 scope==read

grant_type=authentication_code

Open in the browser and login:

http://localhost:8080/oauth/authorize?response_type=code&client_id=client&scope=read

You'll be redirected to a non-existing service but you can fetch the code from the URL. Use the code here to get an access token:

curl -v -XPOST -u client:secret "http://localhost:8080/oauth/token?grant_type=authorization_code&scope=read&code={CODE}"

grant_type=client_credentials

To get an access token:

curl -v -XPOST -u client:secret "http://localhost:8080/oauth/token?grant_type=client_credentials&scope=info"
http -a adviceClient:adviceSecret POST "http://localhost:8080/oauth/token?grant_type=client_credentials&scope=advice"

grant_type=[password,refresh_token]

curl -v -XPOST -u client:secret "http://localhost:8080/oauth/token?grant_type=password&username=john&password=12345&scope=read"

To get an access token and a refresh token:

curl -v -XPOST -u client:secret "http://localhost:8080/oauth/token?grant_type=password&username=john&password=12345&scope=read"

To get the public key:

curl -u client:secret "http://localhost:8080/oauth/token_key"

Generation:

keytool -genkeypair -alias ssia -keyalg RSA -keysize 2048 -keypass ssia123 -keystore ssia.jks -storepass ssia123

Get public key:

keytool -list -rfc --keystore ssia.jks | openssl x509 -inform pem -pubkey

Resource server

Access resource with token:

curl -H "Authorization:Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9..." "http://localhost:8081/profile/john"
curl -H "Authorization:Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9..." "http://localhost:8081/metric/john"
