routes.js和login.ejs的新代码：

视图（login.ejs）：
`<!DOCTYPE html>

我也可以像= http://localhost:8080/profile/emailAddress一样。
注册我的网站时会提供emailAddress。 emailAddress存储在我设置的数据库中。

app.get('/profile', isLoggedIn, function (req, res) {
// store userId on login into session or any global variable
var userId = req.session.userId
res.redirect('/profile/'+userId)
}); // =>directs to http://localhost:8080/profile for every signup.
使用附加参数
创建新路线app.get('/profile/:id', function (req, res) {
var id = req.params.id
res.render('./pages/profile.ejs', {user: id});
})
答案 1 :(得分：0)
您应该使用请求参数。使用快递，您可以执行以下操作：
app.get('/profile/:id', isLoggedIn, function (req, res) {
var id = req.params.id;
//do with id whatever you want
res.render('./pages/profile.ejs', {user: req.user});
});
在您的isLoggedIn中间件中，您将拥有以下内容：
function(req, res, next) {
if (isLoggedIn) { //check if the user is logged in
req.user = user; //fetch the user from the DB or wherever you have it
}
}
在您的视图中，您将使用用户的ID来构建网址：
<a href="/profile/<%=user.id%>"><%=user.name%></a>
