How to get authorization code ? Then access token ?

[domiq44]

Hello,

Very interesting job.
Thank you for it.

I would like, in order, retrieve (See What is the OAuth 2.0 Authorization Code Grant Type?) :

1. authorization code using :
   1. url http://localhost:9191/api/oauth/authorize,
   2. client_id.
2. access token using :
   1. url http://localhost:9191/api/oauth/token,
   2. authorization code retrieved before.

So I've tried this command line (using curl) :

curl -i http://localhost:9191/api/oauth/authorize?client_id=rajithapp&response_type=code&redirect_uri=http://127.0.0.1:12345&scope=openid+read+write

but I am redirected to http://localhost:9191/api/login with no login window !?

Then, I will be able to retrieve access token.

Can you help me please ?
