I want to get data from cloud foundry using curl, but I\'m not able to authenticate (oauth against CF). Please, could someone point me to and example how to get oauth token?
This isn't exactly what you asked for, but if a recent cf cli is installed you can login as normal and then use the cf curl command to run raw requests.
For example
$ cf login (or cf auth for non-interactive login)
$ cf curl /v2/spaces/c4e73f65-4dbc-47dc-9d21-e8c566c40587/summary
To use actual curl, again using the cf cli, retrieve the bearer token with:
$ cf oauth-token
Then execute your curl command with an Authorization header:
$ curl --header 'Authorization: bearer ...' https://api.example.com/v2/spaces/c4e73f65-4dbc-47dc-9d21-e8c566c40587/summary
