How to control the access
The authorization determines a request based on {subject, object, action}
, which means what subject
can perform what action
on what object
. In this plugin, the meanings are:
subject
: the logged-on user nameobject
: the URL path for the web resource like "dataset1/item1"action
: HTTP method like GET, POST, PUT, DELETE, or the high-level actions you defined like "read-file", "write-blog"
For how to write authorization policy and other details, please refer to the Casbin's documentation.
