node.js - 计算电子邮件节点 js 的登录尝试次数

Question

如何计算用户电子邮件的登录尝试。我想将它们存储在会话中。我尝试：

req.session[req.body.email] = req.session[req.body.email] + 1;

但undefined + 1 = NaN

我该怎么做？

Answer 1

为什么不只是？:)

req.session['mailAttempts'] = req.session['mailAttempts'] + 1;

并且不要忘记启用会话

app.use(express.session({secret: '1234567890QWERTY'}));
