"""
JWT 表示 「JSON Web Tokens」。https://jwt.io/

它是一个将 JSON 对象编码为密集且没有空格的长字符串的标准。

通过这种方式，你可以创建一个有效期为 1 周的令牌。然后当用户第二天使用令牌重新访问时，你知道该用户仍然处于登入状态。
一周后令牌将会过期，用户将不会通过认证，必须再次登录才能获得一个新令牌。

我们需要安装 python-jose 以在 Python 中生成和校验 JWT 令牌：pip install python-jose[cryptography]

PassLib 是一个用于处理哈希密码的很棒的 Python 包。它支持许多安全哈希算法以及配合算法使用的实用程序。
推荐的算法是 「Bcrypt」：pip install passlib[bcrypt]
