Sample OpenId-Connect request

Authorization code flow

1. The client application creates a random String, named nonce, and sends to he user the following URL:

https://<identityprovider>/authorization? redirect_uri=https://<serviceprovider>/response& client_id=MYCLIENT& nonce=12345679801234567890& scope=openid& response_type=code

2. Then, the user will be asked for a username and password, or any other means of authentication. After authenticating the user, the browser will be redirected to the URL configured in the service provider page, adding a one-time authorization code.

https://<serviceprovider>/response/? code=XXXXXXXXXXXXXXX& nonce=12345679801234567980

3. Once the service provider has received the one-time authorization code, it can connect to the identity provider to retrieve the oAuth token, as well as the OpenID token.

POST https://<YOUR_SERVER>:2443/token Accept: application/json Authorization: Basic dGVzdDp0ZXN0 Content-Type: application/x-www-form-urlencoded   grant_type=authorization_code&code=XXXXXXXXXXXX

The parameters sent are:

• Authorization: contains, coded in base 64, the client id and the client secret, as it would have been sent for a standard Basic authentication header. The identity provider will match these against the stored credentials.

• grant_type: should be authorization_code.

• code: should be the one-time authorization code received in the previous requested.

The response will look like this

{     "access_token":"8bDP2P...",     "refresh_token":"gjLmSW...",     "id_token":"eyJra.eyJ.LQ_XtHKr.RY3A4...",     "token_type":"Bearer",     "expires_in":11998 }

• The id_token  tag contains the OpenId token.
• The access_token tag contains the oAuth token.

4. Before the number of seconds specified om expires_in are elapsed, the token can be renewed by invoking again the token endpoint changing the grant_type:

POST https://<YOUR_SERVER>:2443/token Accept: application/json Authorization: Basic dGVzdDp0ZXN0 Content-Type: application/x-www-form-urlencoded   grant_type=refresh_token&refresh_token=XXXXXXXXXXXX

The parameters sent are:

• Authorization: contains, coded in base 64, the client id and the client secret, as it would have been sent for a standard Basic authentication header. The identity provider will match these against the stored credentials.
• grant_type: should be refresh_token.
• refresh_code: should be refresh code received in the previous requested.

The response will look like this:

{     "access_token":"8bDP2P...",     "refresh_token":"gjLmSW...",     "id_token":"eyJra.eyJ.LQ_XtHKr.RY3A4...",     "token_type":"Bearer",     "expires_in":11998 }
