在 Express 中向浏览器发送 cookie 失败

Question

我能够成功创建我的 cookie，并且可以在控制台中清楚地看到它们。现在的问题是我想将这些 cookie 发送到浏览器，但我无法做到这一点。当我打开我的 Chrome 并转到 cookie 时，它​​们并不存在

我已将安全选项设置为 false 并将 httponly 设置为 false，但它似乎不起作用

    req.session.cart = cart;
    var cookieValue = JSON.stringify([req.session.cart],{secure:false, maxAge: 180 * 60 * 1000, httpOnly: false });       
    var cookie = req.cookies.cookieName;
        // no: set a new cookie
        res.cookie('cookieName',cookieValue);
        console.log('cookie created successfully');
        // yes, cookie was already present 
        console.log('cookie exists', cookieValue);
    res.redirect('/');

当我创建 cookie 时，它​​们必须出现在浏览器中

就像@Mike 'Pomax' Kamermans 提到的，我认为这可能与res.redirect 有关。尝试将它们添加到您的 / 路由中。像这样的：

// Requires cookie-parser
// https://expressjs.com/en/api.html#req.cookies
// https://github.com/expressjs/cookie-parser

app.post('/cart', function(req, res){
    req.session.cart = cart;
    var cookieValue = JSON.stringify([req.session.cart],{secure:false, maxAge: 180 * 60 * 1000, httpOnly: false });       
    var cookie = req.cookies.cookieName;
    if(!cookie) {
        res.cookie('cookieName',cookieValue);
        console.log('cookie created successfully');
    } else {
        console.log('cookie exists', cookieValue);
    }
    res.redirect('/');
});

app.get('/', function(req, res){
    if((typeof req.cookies == "object")&&(Object.keys(req.cookies).length>0)) {
        console.log("Cookies are present");
        // copy cookies from req to res
        for(var o=0; o<Object.keys(req.cookies).length; o++) {
            var key = Object.keys(req.cookies)[o];
            res.cookie(key,req.cookies[key]);
        }
    }
    res.status(200).send("OK");
});
