Question

我的应用程序使用，node.js，expressJS，jQuery。使用jQuery cookie插件，我从客户端创建了一个cookie，然后可以成功读取它。我想从服务器端读取该cookie（node.js，表达js），但不能。

var products_cart=new Array();



for(var i =1; i<5; i++){
var prod_cart_indiv= new Object();  

prod_cart_indiv.prod_id=i;

prod_cart_indiv.price=(200+i);
prod_cart_indiv.num_total=(4+i);
prod_cart_indiv.name='printing products _ '+i;
prod_cart_indiv.img='a_'+i+'.jpg';

products_cart.push(prod_cart_indiv);

}// end of for loop
$.cookie('products_cart',JSON.stringify(products_cart));
var products_cart_found =JSON.parse($.cookie('products_cart'));

if(window.console){


    console.log("Logging products_cart_found ");

    console.dir(products_cart_found);

}

服务器端node.js代码：

var util = require('util');
 app.get('*',function(req,res){

 var get_cookies = function(request) {
  var cookies = {};
  request.headers && request.headers.cookie.split(';').forEach(function(cookie) {
    var parts = cookie.match(/(.*?)=(.*)$/)
    cookies[ parts[1].trim() ] = (parts[2] || '').trim();
  });
  return cookies;
};

 var products_cart_found= get_cookies(req)['products_cart'];

 console.log(util.inspect(products_cart_found, false, null));

});

我在命令提示符中找到的是：

'%5B%7B%22prod_id%22%3A1%2C%22price%22%3A201%2C%22num_total%22%3A5%2C%22name%22%
    3A%22printing%20products%20_%201%22%2C%22img%22%3A%22a_1.jpg%22%7D%2C%7B%22prod_
    id%22%3A2%2C%22price%22%3A202%2C%22num_total%22%3A6%2C%22name%22%3A%22printing%2
    0products%20_%202%22%2C%22img%22%3A%22a_2.jpg%22%7D%2C%7B%22prod_id%22%3A3%2C%22
    price%22%3A203%2C%22num_total%22%3A7%2C%22name%22%3A%22printing%20products%20_%2
    03%22%2C%22img%22%3A%22a_3.jpg%22%7D%2C%7B%22prod_id%22%3A4%2C%22price%22%3A204%
    2C%22num_total%22%3A8%2C%22name%22%3A%22printing%20products%20_%204%22%2C%22img%
    22%3A%22a_4.jpg%22%7D%5D'

然而在浏览器控制台中，我得到了下面的输出（手工制作以呈现）：

Array[4] 
 Object: img: "a_1.jpg"name: "printing products _ 1"num_total: 5price: 201prod_id: 1
 Object: img: "a_2.jpg"name: "printing products _ 2"num_total: 6price: 202prod_id: 2
 Object: Objectimg: "a_3.jpg"name: "printing products _ 3"num_total: 7price: 203prod_id: 3
 Object: Objectimg: "a_4.jpg"name: "printing products _ 4"num_total: 8price: 204prod_id: 4

如何在变量中获取cookie值，以便我可以迭代它，就好像它是一个对象数组＆gt;

node.js，expressJS - 无法正确读取包含对象数组的cookie值
