 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 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：http: //127.0.0.1 :8080

cookie 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 打开一个新选项卡（不关闭浏览器）时，cookie 会保留。

但是，当我关闭浏览器（chrome/IE/firefox）并再次打开此 url 时，cookie 不存在！

为什么？即使我关闭计算机并重新启动它，它仍会记住我通过 coockis 的登录信息，我怎样才能使它像 facebook？

谢谢

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。关闭浏览器后将立即删除。

为了避免这种情况，只需为 cookie 设置一个过期时间，例如此处为一天：

var expireDate = new Date(); 
expireDate.setDate(expireDate.getDate() + 1); 

$cookies.put('Name', $scope.Name, {
  expires: expireDate
});
