 var app = angular.module('MyApp', ['ngCookies']);
        app.controller('MyController', function ($scope, $window, $cookies) {
            $scope.WriteCookie = function () {
                $cookies.put("Name", $scope.Name);
            };
            $scope.ReadCookie = function () {
                $window.alert($cookies.get('Name'));
            };
            $scope.RemoveCookie = function () {
                $cookies.remove('Name');
            };
        });

我为angular中的cookie编写了这个简单的demp应用程序。

每当我输入这个(通过nodeJS(并转到这个url时：http://127.0.0.1:8080

cookie已预先存在于浏览器的cookie中。当我单击刷新或关闭选项卡并使用此url打开新选项卡(不关闭浏览器(时，cookie会保留。

然而，当我关闭浏览器(chrome/IE/firefox(并再次打开此url时，cookie不在那里！

为什么？即使我关掉电脑重新启动，它也会记住我的cookis登录信息，我怎么能让它像facebook一样呢？

感谢

这是因为如果您不为cookie设置过期时间，它将被创建为会话cookie。一旦关闭浏览器，它就会被删除。

为了避免这种情况，只需为cookie设置一个到期时间，例如这里为一天：

var expireDate = new Date(); 
expireDate.setDate(expireDate.getDate() + 1); 
$cookies.put('Name', $scope.Name, {
  expires: expireDate
});
