angularjs 前端传递人员验证信息给后台

.config(function($httpProvider) {    $httpProvider.interceptors.push(function($rootScope,$timeout) {        return {            request: function(config) {                $rootScope.$broadcast('loading:show');                //如果User已经登录，向拦截器的request中加入人员的账号和token                if(window.sessionStorage["islogin"]=="true"){                    var auth=window.sessionStorage["useraccount"]+ "|"+window.sessionStorage["userid"];                    config.headers["Authorization"] = auth;                }                return config            },            response: function(response) {                $rootScope.$broadcast('loading:hide')                return response            }        }    })})

后台.net api 接收值：
