登錄的js代碼大致是這樣，輸入用戶名和密碼可以獲取到token，要怎么把token延續(xù)到后續(xù)相關頁面里都能用到？var App = angular.module('lcdApp', []);App.controller('loginCtrl', function ($scope, $http, $window) {$scope.loginClick = function () {         $http.post('url', {         username: $scope.username,         password: $scope.password     }).success(function (data, status, headers, config) {         })                      .error(function (data, status, headers, config) {             console.log("http usrreg error!");         }); }});
