我正在用 Flask 构建一个基本应用程序：它有一个唯一的路由，只请求一个令牌身份验证，即如果标头中提供的令牌是正确的，那么请求就得到了满足。为此，我同时安装了Flask和Flask-Security. 这是我的应用程序的一个片段：

from flask import Flask
from flask.ext.security import auth_token_required
from flask.ext.security import Security

app = Flask(__name__)
app.config['SECURITY_TOKEN_AUTHENTICATION_KEY'] = 'mytoken'
security = Security(app)

@app.route('/myurl')
@auth_token_required
def myrequest():
    return 'OK'

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

我通过运行来测试它：

$ curl -H 'Authorization: Token token="mytoken"' localhost:5000/myurl

甚至：

$ curl localhost:5000/myurl

但是，我收到以下错误：

Traceback (most recent call last):

    _security = LocalProxy(lambda: current_app.extensions['security'])
KeyError: 'security'

你知道错误在哪里吗？是在应用程序中还是在 Flask 库之间存在一些冲突？

编辑：添加Security(app)初始化
