Add support for Plex JWT Authentication

[JonnyWong16]

Description

Ref.: https://developer.plex.tv/pms/#section/API-Info/Authenticating-with-Plex

• Added new myplex.MyPlexJWTAuth class to handle Plex JWT authentication.
• Added new utils.plexJWTAuth() helper function for Plex JWT authentication.

Example using class:

from plexapi.myplex import MyPlexAccount, MyPlexJWTLogin # Method 1: Generate a new Plex JWT using Plex OAuth jwtlogin = MyPlexJWTLogin( oauth=True, scopes=['username', 'email', 'friendly_name'] ) jwtlogin.generateKeypair(keyfiles=('private.key', 'public.key')) print(f'Login to Plex at the following url:\n{jwtlogin.oauthUrl()}') jwtlogin.run() jwtlogin.waitForLogin() jwtToken = jwtlogin.jwtToken account = MyPlexAccount(token=jwtToken) # Method 2: Generate a new Plex JWT using an existing Plex token and keypair jwtlogin = MyPlexJWTLogin( token='2ffLuB84dqLswk9skLos', keypair=('private.key', 'public.key'), scopes=['username', 'email', 'friendly_name'] ) jwtlogin.registerDevice() jwtToken = jwtlogin.refreshJWT() account = MyPlexAccount(token=jwtToken) # Refresh an existing Plex JWT jwtlogin = MyPlexJWTLogin( jwtToken=jwtToken, keypair=('private.key', 'public.key'), scopes=['username', 'email', 'friendly_name'] ) if not jwtlogin.verifyJWT(): jwtToken = jwtlogin.refreshJWT() account = MyPlexAccount(token=jwtToken)

Example using helper function:

from plexapi.utils import plexJWTAuth # Generate a new Plex JWT using Plex OAuth # Client identifier and keypair will be generated automatically account = plexJWTAuth(scopes=['username', 'email', 'friendly_name'])
