angularJS创建拦截注入，为每个$http请求添加auth权限请求：

var app = angular.module("myApp", ["ngRoute", "ngResource"])
    .constant('ACCESS_LEVELS',{
        PUB:1,
        USER:2
    })
    .config(["$routeProvider", "$httpProvider","ACCESS_LEVELS", function ($routeProvider, $httpProvider,ACCESS_LEVELS) {

        //设置http头
        $httpProvider.defaults.headers.common["X-Response-Code-By"] = "Angular1.5.8";

        var interceptor = function ($q, $rootScope, auth) {
            return {
                'response': function (res) {
                    //登录成功,设置authkey
                    if (res.config.url.indexOf('/api/v1/login')!=-1) {
                        auth.set(res.data.auth);
                    }
                    return res;
                },
                'responseError': function (rejection) {
                    switch (rejection.status) {
                        case 401:
                            if (res.config.url.indexOf('/api/v1/login')!=-1) {
                                // 如果当前不是在登录页面
                                $rootScope.$broadcast('auth:loginRequired');
                            }

                            break;
                        case 500:
                            $rootScope.$broadcast('server:error');
                            break;

                    }
                    return $q.reject(rejection);

                    }
