我尝试使用烧瓶登录构建谷歌登录。我在这里找到了主题 Using Google OAuth2 with Flask
我能够移植接受的答案以使用 Requests-OAuthlib 而不是 Rauth。在撰写本文时，该包的最后一次提交是在 2019 年 6 月，目前被 30K+ 存储库使用。
初始化.py _
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager
import dir
from flask_mail import Mail
# init SQLAlchemy so we can use it later in our models
db = SQLAlchemy()
mail = Mail()
GOOGLE_LOGIN_CLIENT_ID = "mygoogle API id .apps.googleusercontent.com" #I am sure It is correct
GOOGLE_LOGIN_CLIENT_SECRET = "my_secret_key"
def create_app():
app = Flask(__name__)
app.debug = True
app.config['SECRET_KEY'] = 'secret-key-goes-here'
# app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///db.sqlite'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:////' + str(dir.dir) + '/admin.sqlite'
app.config['MAIL_SERVER'] = 'smtp.gmail.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USERNAME'] = 'ruaxe.sdafsafsafs'
app.config['MAIL_PASSWORD'] = 'uiykejafsaffiqklziccld'
app.config['MAIL_USE_TLS'] = False
app.config['MAIL_USE_SSL'] = True
app.config['OAUTH_CREDENTIALS'] = {
'google': {
'id': GOOGLE_LOGIN_CLIENT_ID,
'secret': GOOGLE_LOGIN_CLIENT_SECRET
}
}
mail.init_app(app)
db.init_app(app)
with app.app_context():
db.create_all()
login_manager = LoginManager()
login_manager.login_view = 'auth.login'
login_manager.init_app(app)
from .models import User
@login_manager.user_loader
def load_user(user_id):
# since the user_id is just the primary key of our user table, use it in the query for the user
return User.query.get(int(user_id))
# blueprint for auth routes in our app
from .auth import auth as auth_blueprint
app.register_blueprint(auth_blueprint)
# blueprint for non-auth parts of app
from .main import main as main_blueprint
app.register_blueprint(main_blueprint)
return app
然后我用登录页面构建 auth.py
auth = Blueprint('auth', __name__)
@auth.route('/login', methods=['GET'])
def login():
if current_user is not None and current_user.is_authenticated:
return redirect(url_for('main.index'))
return render_template('login.html')
我在 main.py 中构建的用户视图页面

然后我运行程序，我可以得到链接作为代码
def authorize(self):
auth_url, _ = self.session.authorization_url(
self.openid_config["authorization_endpoint"])
print(auth_url) ##### This function run
return redirect(auth_url)

但我尝试将电子邮件打印为路线配置文件中的代码
oauth = OAuthSignIn.get_provider(provider)
name, email = oauth.callback()
print("da lay duoc email", email)
什么都没来！所以任何人都可以帮助我 谢谢大家
