账号安全服务怎么创建

from flask import Flask, render_template, redirect, url_for
from flask_login import LoginManager, UserMixin, login_user, login_required, logout_user, current_user

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

login_manager = LoginManager()
login_manager.init_app(app)

class User(UserMixin):
    def __init__(self, id):
        self.id = id

@login_manager.user_loader
def load_user(user_id):
    return User(user_id)

@app.route('/login', methods=['GET', 'POST'])
def login():
    if current_user.is_authenticated:
        return redirect(url_for('index'))
    # 这里应该有实际的登录逻辑，例如验证用户名和密码
    user = User(1)  # 假设用户ID为1的用户已验证成功
    login_user(user)
    return redirect(url_for('index'))

@app.route('/logout')
@login_required
def logout():
    logout_user()
    return redirect(url_for('index'))

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

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