Backend for user authorization

Users must be pre-configured according to the new Watcher structure

How it works:

  • An operator needs to realize the HTTP request handler, that has the logic to authenticate users.
  • The operator enters the path to the Flussonic Watcher authentication backend (Settings — Authentication backend).
  • A user logs into Flussonic Watcher using login/password.
  • Watcher transfers this data to the backend operator in a request payload.
  • Backend checks the incoming data.
  • If the user can be authenticated, the system returns the 200 HTTP code.
  • If the authentication data is incorrect, it returns the 403 HTTP code.
  • If the user is not found, the system gives 404.
  • If the authentication backed was out of reach or send the response less than 2 seconds. The user check if being done in the Watcher’s database.
    • import falcon, json

class AuthResource:
  def on_get(self, req, resp):
    print "GET %r\n%r" % (req.uri, req.params)
    login = req.params.get('login', None)
    password = req.params.get('password', None)
    if not login or not password:
      print 'incorrect request login: %r, pass: %r' % (login, password)
      resp.status = falcon.HTTP_400
      return

    if login == 'user0':
      if password == 'letmein':
        return
      resp.status = falcon.HTTP_403
      return

    if login == 'user1':
      if password == 'letmein':
        return
      resp.status = falcon.HTTP_403
      return

    resp.status = falcon.HTTP_404

app = falcon.API()
ad = AuthResource()

app.add_route('/auth', ad)
