angular中的http拦截器Interceptors的实现

commonService.config(['$httpProvider',function($httpProvider){

    //$httpProvider.defaults.headers.common = {'X-Auth-Token': $.cookie('x_auth_token'),'Content-Type':'application/json;charset=UTF-8'};

    //添加拦截器；

    $httpProvider.interceptors.push(function ($q) {

      return {

        request: function (obj) {
               

          $('.loading').show();

          obj.headers['X-Auth-Token'] = $.cookie('x_auth_token');

          if(!obj.headers['Content-Type'])

            obj.headers['Content-Type'] = 'application/json;charset=UTF-8';

 

          var url, params,method;

       

          //加盟店请求

          mylog('jiamengdian::',sessionStorage.getItem("chainStorefrnId"));

          if(sessionStorage.getItem("chainStorefrnId")){

            //增加操作人id，name和storeid等信息

            //操作人姓名

            var operatorName = $.cookie("userType") == "employee" ? decodeURI($.cookie("username")) : decodeURI($.cookie("frnName"));

            //操作人id

            var operatorId = $.cookie("userId");

            }

            //处理url，区分首次授信还是追加授信

            var flag_url = sessionStorage.getItem('chainStoreFlag');

            if(flag_url && flag_url == "firstcredit"){
