如何在Flask登录中修复Google登录

GOOGLE_CLIENT_ID = 'your_client_id'
GOOGLE_CLIENT_SECRET = 'your_client_secret'

from flask import Flask, redirect, url_for
from flask_dance.contrib.google import make_google_blueprint, google

app = Flask(__name__)
app.secret_key = 'your_secret_key'

blueprint = make_google_blueprint(
    client_id=app.config['GOOGLE_CLIENT_ID'],
    client_secret=app.config['GOOGLE_CLIENT_SECRET'],
    scope=['profile', 'email']
)
app.register_blueprint(blueprint, url_prefix='/login')

@app.route('/')
def index():
    if not google.authorized:
        return redirect(url_for('google.login'))
    resp = google.get('/oauth2/v2/userinfo')
    assert resp.ok, resp.text
    return 'You are {email} on Google'.format(email=resp.json()['email'])

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