[keycloak-user] Access Token And PRT(request party token), which one should I use to access the resource protected by keycloak

[Yizhou Jiang(Yizhou)]

Hi,
               By reading the document of KeyCloak ,I found that I can use a Access-token  or a PRT(request party token) to access the resources protected by keycloak.

1  Use  PRT: https://keycloak.gitbooks.io/documentation/authorization_services/topics/enforcer/keycloak-enforcement-bearer.html

GET /my-resource-server/my-protected-resource HTTP/1.1
Host: host.com
Authorization: Bearer ${RPT}

2  Use access token: https://github.com/keycloak/keycloak-quickstarts/blob/master/app-jee-html5/src/main/webapp/app.js

line 38

if (keycloak.authenticated) {
       req.setRequestHeader('Authorization', 'Bearer ' + keycloak.token);
}

   I'm  confused about the  difference  between them.  I don't know  When I should use access token , and when I should use another one ?
I am looking forward to your reply.

thanks ,
yizhou
