ExpressJS設置/獲取/使用Cookie

設置我與

response.cookie('name', 'My name');

我想獲得我的餅乾這樣的cookie，而它之前的工作，但我改變了快速配置，我不知道是什麼，現在似乎是這個問題。

request.cookies is and empty Object

我快速配置：

var express = require('express'), 
    api = require('./routes/api'); 

var app = express(); 

app.configure(function() { 
    app.set('port', process.env.PORT || 3000); 
    app.use(express.favicon()); 
    app.use(express.logger('dev')); 
    app.use(express.json()); 
    //app.use(express.bodyParser()); 
    app.use(express.compress()); // New call to compress content 
    app.use(express.cookieParser()); 
    app.use(express.session({secret: 'secret'})); 
    app.use(app.router); 
    app.use(express.methodOverride()); 
    //app.use(express.static(__dirname + '/public')); 
}); 

app.all('*', function(req, res, next) { 
    res.header("Access-Control-Allow-Origin", "*"); 
    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE'); 
    res.header("Access-Control-Allow-Headers", "X-Requested-With, Content-Type"); 
    next(); 
}); 

app.configure('development', function() { 
    app.use(express.errorHandler({ dumpExceptions: true, showStack: true })); 
}); 

app.configure('production', function() { 
    app.use(express.errorHandler()); 
});

設置的Cookie：

exports.singIn = function (req, res) { 
    var mail = req.query.mail, 
     password = req.query.password; 

    return user.find({ 
     mail: mail 
    }).then(function (d) { 
     var user = usersData(u); 

     res.cookie('mail', user.mail, { maxAge: 900000}); 
     res.cookie('password', crypted, { maxAge: 900000}); 
     res.json({ user: user }); 
     return { user: user } 
    }).catch(function() { 
     res.json(400, {"error-tag": "error-sing-in"}); 
     return {"error-tag": "error-sing-in"}; 
    }); 
};

獲取的Cookie：

exports.account = function (req, res) { 
    var mail = req.cookies.mail, 
     password = req.cookies.password; 
    //here req.cookies is an empty object. I don't know why? 
};

你在哪裏調用''singIn'「？ –

我認爲你需要使用cookieSession中間件。請參閱http://stackoverflow.com/a/18510185/446681 –

singIn在用戶使用主密碼和密碼進入時調用。在獲取用戶的所有數據時使用帳戶。 – puppeteer701

2017年的答案..

const cookieParser = require('cookie-parser'); 
const express = require('express'); 
const app = express(); 
app.use(cookieParser());

從傳入的請求得到一個cookie ..

let cookie = req.cookies['cookiename'];

設置一個響應的cookie（這cookie將未來的所有傳入的請求，直到缺失或期滿被髮送）..

res.cookie('cookiename', 'cookievalue', { 
    maxAge: 86400 * 1000, // 24 hours 
    httpOnly: true, // http only, prevents JavaScript cookie access 
    secure: true // cookie must be sent over https/ssl 
});

刪除響應cookie ..

res.cookie('cookiename', 'cookievalue', { 
    maxAge: 0 
});
