        fmt.Fprintf(w, "Welcome to the home page!")

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:

  1. subject: the logged-on user name
  2. object: the URL path for the web resource like "dataset1/item1"
  3. 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.
