使用快速会话进行身份验证

我正在建立在线购物商店或电子商务，并且我在很多事情上都使用快速会话。

示例：购物车，身份验证用户

我根据sessionID将数据图表列表存储在数据库中，因此当用户访问网站时，该用户无需登录即可添加到购物车。

除了登录外，要检查用户是否登录，我已经检查了用户中的sessionID，并在数据库中检查了sessionID是否在数据库中。

使用Google或Facebook登录时，我使用护照进行身份验证，成功后，我将sessionID存储到数据库中。

iam使用React SPA，express.js和MySQL

我的数据库

表会话：

Table Session

表会话浏览器

Table Session Browser

表格用户

Table User

表用户会话

Table user session

餐车

Table Cart

我在做什么是正确的？

那护照呢？因为据我所知，护照使用标题授权令牌

示例添加到购物车：

        let ip_address = req.headers['x-forwarded-for'] || req.connection.remoteAddress;
    let ua = UAparser(req.headers['user-agent']);
    if (ip_address.substr(0, 7) == "::ffff:") {
        ip_address = ip_address.substr(7)
    }
