// 示例：使用Python Flask 实现 OAuth2 登录

from flask import Flask, redirect, url_for

from flask_oauthlib.client import OAuth

app = Flask(__name__)

oauth = OAuth(app)

google = oauth.remote_app(

'google',

consumer_key='your-client-id',

consumer_secret='your-client-secret',

request_token_params={'scope': 'email'},

base_url='https://www.googleapis.com/oauth2/v1/',

request_token_url=None,

access_token_method='POST',

access_token_url='https://accounts.google.com/o/oauth2/token',

authorize_url='https://accounts.google.com/o/oauth2/auth'

)

@app.route('/login')

def login():

return google.authorize(callback=url_for('authorized', _external=True))

@app.route('/authorized')

def authorized():

resp = google.authorized_response()

if resp is None:

return 'Access denied.'

return 'Logged in as: ' + resp['email']

if __name__ == '__main__':

app.run()
