直接上代碼：

angular.module('webb-ui').factory('authInterceptor', ['$q','$rootScope','$location','$injector','$timeout',function ($q,$scope,$location,$injector,$timeout) {    function isNotPRiv(url){        return url.indexOf("/priv/") === -1    }    var authInterceptor = {        'request': function(config) {            var deferred = $q.defer();            var url = config.url;            deferred.resolve(config);            return deferred.promise;        },        'response':function(response){            return response;        },        'responseError': function(rejection) {            var rootScope = $injector.get('$rootScope');            if(isNotPriv(rejection.config.url)){                var status = rejection.status;                if(status === 403){                    $scope.four_zero_th = true;//自己的業務邏輯處理代碼                    rootScope.selectEtl();                    return rejection;                }else if(status === 401) {                    $scope.four_zero_one = true;                    rootScope.selectEtl();                    return rejection;                }            }            return $q.reject(rejection);        }    };    return authInterceptor;}]);
說明：responseError 此例子主要是對請求異常進行統一的攔截處理。
angular.module('webb-ui')
.config(['$stateProvider', '$urlRouterProvider', '$httpProvider', '$locationProvider',    function ($stateProvider, $urlRouterProvider, $httpProvider, $locationProvider) {        $httpProvider.interceptors.push('authInterceptor');        /*        *這里刪除一個$injector，解決不能獲取code碼的問題。        * */        //$httpProvider.interceptors.pop();
}]);
