我必须设计一个提供Flask服务和Dash服务的Web应用程序。例如，我想在Flask中创建一个结合Dash应用程序的登录名。问题是我无法将烧瓶登录名与破折号绑定。我需要一个类似“ @require_login”的方法来过滤对Dash服务的访问。代码如下：

app_flask = Flask(__name__)

app_flask.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:////login.db'
app_flask.config['SECRET_KEY'] = 'thisissecret'

db = SQLAlchemy(app_flask)
login_manager = LoginManager()
login_manager.init_app(app_flask)

class User(UserMixin, db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(30), unique=True)

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

@app_flask.route('/')
def index():
    user = User.query.filter_by(username='admin').first()
    login_user(user)
    return 'You are now logged in!'

@app_flask.route('/logout')
@login_required
def logout():
    logout_user()
    return 'You are now logged out!'

@app_flask.route('/home')
@login_required
def home():
    return 'The current FLASK user is ' + current_user.username
