angular ngCookies 在重启浏览器后不保存 cookie

Question

 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');
            };
        });

  <div ng-app="MyApp" ng-controller="MyController">
        Name:
        <input type="text" ng-model="Name" />
        <br />
        <br />
        <input type="button" value="Write Cookie" ng-click="WriteCookie()" />
        <input type="button" value="Read Cookie" ng-click="ReadCookie()" />
        <input type="button" value="Remove Cookie" ng-click="RemoveCookie()" />
    </div>

我在 angular 中为 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 保存在浏览器的 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 不存在了！

为什么？我怎样才能让它像 facebook 一样，即使我关闭我的电脑并重新启动它也会记住我的 coockis 登录信息？

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。一旦您关闭浏览器，它就会被删除。

为了避免这种情况，只需为 cookie 设置一个过期时间，例如在这里呆一天：

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

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

angular ngCookies doesn't save cookies after restarting the browser
