python-3.x - 「flask_oauthlib.client」を「authlib.flask.client」に更新/変換 - ユーザーなしで Microsoft Graph v2 アクセス

Question

私の目標はこれを実装することです: https://github.com/Azure-Samples/active-directory-python-flask-graphapi-web-v2

新しい Authlib ライブラリを使用。 https://github.com/lepture/authlib

証明書 (ユーザーログインなし) で認証し、Microsoft の Graph API を使用して Azure AD (v2.0 エンドポイント) SharePoint ドキュメントライブラリからデータを取得するアプリが必要です。

これは「flask_oauthlib」を使用した元のコードです。

from flask import Flask, redirect, url_for, session, request, jsonify, render_template
from flask_oauthlib.client import OAuth, OAuthException

# from flask_sslify import SSLify

from logging import Logger
import uuid

app = Flask(__name__)
# sslify = SSLify(app)
app.debug = True
app.secret_key = 'development'
oauth = OAuth(app)

# Put your consumer key and consumer secret into a config file
# and don't check it into github!!
microsoft = oauth.remote_app(
    'microsoft',
    consumer_key='Register your app at apps.dev.microsoft.com',
    consumer_secret='Register your app at apps.dev.microsoft.com',
    request_token_params={'scope': 'offline_access User.Read'},
    base_url='https://graph.microsoft.com/v1.0/',
    request_token_url=None,
    access_token_method='POST',
    access_token_url='https://login.microsoftonline.com/common/oauth2/v2.0/token',
    authorize_url='https://login.microsoftonline.com/common/oauth2/v2.0/authorize'
)


@app.route('/')
def index():
    return render_template('hello.html')

@app.route('/login', methods = ['POST', 'GET'])
def login():

    if 'microsoft_token' in session:
        return redirect(url_for('me'))

    # Generate the guid to only accept initiated logins
    guid = uuid.uuid4()
    session['state'] = guid

    return microsoft.authorize(callback=url_for('authorized', _external=True), state=guid)

@app.route('/logout', methods = ['POST', 'GET'])
def logout():
    session.pop('microsoft_token', None)
    session.pop('state', None)
    return redirect(url_for('index'))

@app.route('/login/authorized')
def authorized():
    response = microsoft.authorized_response()

    if response is None:
        return "Access Denied: Reason=%s\nError=%s" % (
            response.get('error'),
            request.get('error_description')
        )

    # Check response for state
    print("Response: " + str(response))
    if str(session['state']) != str(request.args['state']):
        raise Exception('State has been messed with, end authentication')

    # Okay to store this in a local variable, encrypt if it's going to client
    # machine or database. Treat as a password.
    session['microsoft_token'] = (response['access_token'], '')

    return redirect(url_for('me'))

@app.route('/me')
def me():
    me = microsoft.get('me')
    return render_template('me.html', me=str(me.data))



# If library is having trouble with refresh, uncomment below and implement refresh handler
# see https://github.com/lepture/flask-oauthlib/issues/160 for instructions on how to do this

# Implements refresh token logic
# @app.route('/refresh', methods=['POST'])
# def refresh():

@microsoft.tokengetter
def get_microsoft_oauth_token():
    return session.get('microsoft_token')

if __name__ == '__main__':
    app.run()

これまでに「authlib.flask」に更新したコードは次のとおりです。

from flask import Flask
from flask import redirect, url_for, session, request, jsonify, render_template
from authlib.flask.client import OAuth
from logging import Logger

import uuid


app = Flask(__name__)

app.debug = True
app.secret_key = 'development'
oauth = OAuth(app)

# Put your consumer key and consumer secret into a config file
    # and don't check it into github!!
microsoft = oauth.register(
    'microsoft',
    client_id='Register your app at apps.dev.microsoft.com',
    client_secret='Register your app at apps.dev.microsoft.com',
    request_token_params={'scope': 'offline_access User.Read'},
    api_base_url='https://graph.microsoft.com/v1.0/',
    request_token_url=None,
    access_token_method='POST',
    access_token_url='https://login.microsoftonline.com/common/oauth2/v2.0/token',
    authorize_url='https://login.microsoftonline.com/common/oauth2/v2.0/authorize',
)

@app.route('/')
def index():
    return render_template('hello.html')

@app.route('/login', methods = ['POST', 'GET'])
def login():
    if 'microsoft_token' in session:
        return redirect(url_for('me'))

    # Generate the guid to only accept initiated logins
    guid0 = uuid.uuid4()
    guid = guid0.bytes
    session['state'] = guid

    return microsoft.authorize_redirect(url_for('authorized', _external=True), state=guid)

@app.route('/logout', methods = ['POST', 'GET'])
def logout():
    session.pop('microsoft_token', None)
    session.pop('state', None)
    return redirect(url_for('index'))

@app.route('/login/authorized')
def authorized():
    response = microsoft.authorize_access_token()

    if response is None:
        return "Access Denied: Reason=%s\nError=%s" % (
            response.get('error'),
            request.get('error_description')
        )

    # Check response for state
    print("Response: " + str(response))
    if str(session['state']) != str(request.args['state']):
        raise Exception('State has been messed with, end authentication')

    # Okay to store this in a local variable, encrypt if it's going to client
    # machine or database. Treat as a password.
    session['microsoft_token'] = (response['access_token'], '')

    return redirect(url_for('me'))

@app.route('/me')
def me():
    me = microsoft.get('me')
    return render_template('me.html', me=str(me.data))


# If library is having trouble with refresh, uncomment below and implement refresh handler
# see https://github.com/lepture/flask-oauthlib/issues/160 for instructions on how to do this

# Implements refresh token logic
# @app.route('/refresh', methods=['POST'])
# def refresh():

@microsoft.tokengetter
def get_microsoft_oauth_token():
    return session.get('microsoft_token')

if __name__ == '__main__':
    app.run()

私が立ち往生している部分は、何をすべきかです：

@microsoft.tokengetter
def get_microsoft_oauth_token():
    return session.get('microsoft_token')

「Migrate OAuth Client from Flask-OAuthlib to Authlib」の Authlib ドキュメントには、次のように記載されています。

oauth.twitter.get(...) のようなメソッドでリソースにアクセスしたい場合は、すぐに使用できるアクセストークンがあることを確認する必要があります。この部分は、Flask-OAuthlib と Authlib で大きく異なります。

Flask-OAuthlib では、デコレーターによって処理されます。

 @twitter.tokengetter
 def get_twitter_oauth_token():
     token = fetch_from_somewhere()
     return token

tokengetter によって返されるトークンは、タプルまたは辞書にすることができます。しかし、Authlib では dict しか指定できず、Authlib はデコレーターを使用してトークンをフェッチしません。代わりに、この関数をレジストリに渡す必要があります。

 # register the two methods oauth.register('twitter',
     client_id='Twitter Consumer Key',
     client_secret='Twitter Consumer Secret',
     request_token_url='https://api.twitter.com/oauth/request_token',
     request_token_params=None,
     access_token_url='https://api.twitter.com/oauth/access_token',
     access_token_params=None,
     refresh_token_url=None,
     authorize_url='https://api.twitter.com/oauth/authenticate',
     api_base_url='https://api.twitter.com/1.1/',
     client_kwargs=None,
     # NOTICE HERE
     fetch_token=fetch_twitter_token,
     save_request_token=save_request_token,
     fetch_request_token=fetch_request_token, )

「@microsoft.tokengetter」をどうすればよいかわかりません

誰か提案はありますか？
