Python - How To Refresh an JWT Access Token Using Decorators

When you create a big python application, you can began to run into challenges with longer scripts that extended beyond the expiration of a single JWT.

To elegantly solve this, You can use decorators to check the token’s expiration and request a new token if necessary. This article goes over the framework I set up so that you can apply a similar mechanism in your own scripts.

Setting the Scene

import time
import requests

class myAPI():
    host = None
    key = None
    secret = None
    access_token = None
    access_token_expiration = None

    def __init__(self,host,key,secret):
        # the function that is executed when
        # an instance of the class is created
        pass

    def getAccessToken(self):
        # the function that is 
        # used to request the JWT
        pass

    class Decorators():
        @staticmethod
        def refreshToken(decorated):
            # the function that is used to check
            # the JWT and refresh if necessary
            pass

Our class will work by requiring the fields necessary to request the JWT. Without access, there is nothing more our class will do.
