Advanced Rest – Python Flask OAuth change

Hi,

I made a video on a great rest api course in Python.  The oauth section of the course is outdated and uses a deprecated Oauth lib.  The author has not yet had a chance to update the course.

The course:
https://www.udemy.com/course/advanced-rest-apis-flask-python/

I went ahead and make the changes using the newer library with Python 3.8.  I made a video so you can see the changes that needed to be made.

 
In oa.py

import os
from flask import g
from authlib.integrations.flask_client import OAuth

oauth = OAuth()

oauth.register(
	name='github',
	client_id=os.getenv('GITHUB_CONSUMER_KEY', default=None),
	client_secret=os.getenv('GITHUB_CONSUMER_SECRET', default=None),
	access_token_url='https://github.com/login/oauth/access_token',
	access_token_params=None,
	authorize_url='https://github.com/login/oauth/authorize',
	authorize_params=None,
	api_base_url='https://api.github.com/',
	client_kwargs={'scope': 'user:email'},
)

in github_login.py

from flask_restful import Resource, url_for
from flask import url_for, render_template
from flask_jwt_extended import create_access_token, create_refresh_token
from models.user import UserModel
from oa import oauth
import json

class GithubLogin(Resource):
  @classmethod
  def get(cls):    
    redirect_uri = url_for("github.authorize", _external = True)    
    return oauth.github.authorize_redirect(redirect_uri)

class GithubAuthorize(Resource):
  # They already gave us authorization to get details, now we want the access token...
  @classmethod
  def get(cls):
    token = oauth.github.authorize_access_token()
    if token is None:
      error_response = {
        "error":"Error getting token",
        "error_description": "Error getting token"
      }
      return error_response, 401    

    resp = oauth.github.get('user')    
    profile = json.loads(resp.text)    
    username = profile['login']
    email = profile['email']
    user = UserModel.find_by_username(username)
    if not user:
      user = UserModel(username=username, password=None)
      user.save_to_db()
    
    access_token = create_access_token(identity=user.id, fresh=True)
    refresh_token = create_refresh_token(user.id)
    return {"access_token":access_token, "refresh_token":refresh_token}, 200    

In app.py

from authlib.integrations.flask_client import OAuth
....

from oa import oauth
 
...

if __name__ == "__main__":
    db.init_app(app)
    ma.init_app(app)
    oauth.init_app(app)
    print("Initialized OAuth ")   
    #print(f"{oauth.github.client_id} - {oauth.github.client_secret}") 
    app.run(port=5000)
