Hi Boris,
I've created key for admin user and could use the username:password to access to RESTful plugin now.
There's some interface of ceph-rest-api doesn't exist on RESTful plugin, such as:
ceph-rest-api: http://host-name:port/api/v0.1/df
It's used to get df result on ceph.
How to get the same/similar result in RESTful plugin? There's no "df" endpoint in RESTful plugin which only include below endpoints:
/config/cluster: GET
/config/osd: GET, PATCH
/crush/rule: GET
/mon: GET
/osd: GET
/pool: GET, POST
/pool/<arg>: DELETE, GET, PATCH
/request: DELETE, GET, POST
/request/<arg>: DELETE, GET
/server: GET
How to set <arg> for pool & request endpoint? Is there any good reference?
B.R.

Thanks Boris. I'll use the (user, pwd) to do further work.

Most of the endpoints in the restful module are authenticated (the only exception being the root '/' endpoint). This is by design to forbid access to unauthorized personnel. That means that you always need to send an authenticated request.
You can simplify this by storing the (user, pwd) tuple in a tuple and passing the tuple to the request or writing a simple wrapper function that would do that for you.
Alternatively, you should be able to employ cookies (afaik, that is what a browser does when you authenticate) for this sort of thing but it is probably easier to achieve this by the wrapper or stored tuple in Python.
