angular中service封装$http做权限时拦截403等状态及获取验证码倒计时、跨域问题解决

封装$http、做权限时拦截403等状态及获取验证码倒计时：

1. 拦截接口返回状态

   var app = angular.module('app');
   
   app.factory('UserInterceptor', ["$q","$rootScope", "$location", function ($q, $rootScope, $location,$localStorage) {
     return {
       request:function(config){
           config.headers["Authorization"] = 'Bearer ' + localStorage['token'];
         var urlArray = config.url.split("/")
         if(urlArray.indexOf("api") > -1 && config.method == "GET"){
           if(config.url.indexOf("?") > -1){
             config.url = config.url+"&time="+new Date().getTime();
           }else{
             config.url = config.url+"?time="+new Date().getTime();
           }
         }
           return config;
       },
       responseError: function (response) {
         switch(response.status)
         {
           case 401:
             localStorage.clear();
             $location.path("/login");
             break;
           case 403:
             $location.path("/login");
             break;
         }
       }
     };
   }]);

   response.status为返回状态码

2. 封装$http

   app.factory('ResourceGet',function($http,$q){
       var service = {}
       service.callBack = function(action,params){
           var url = ' http://10.0.10.201:8080/';
           var deferred = $q.defer();
           $http({
               method: 'GET',
               url: url+action,
               params: params
           }).success(function(data){
               deferred.resolve(data);
           })
           return deferred.promise;
       }
       return service
   });
   
   app.factory('ResourcePut', function ($http, $q) {
     var service = {}
     service.callBack = function ( action, params ) {
       var url = 'http://10.0.10.201:8080/'
         var deferred = $q.defer()
         $http({
           method: 'PUT',
           url: url + action,
           data: params,
           headers : {'Content-Type': 'application/json; charset=utf-8'}
         }).success(function (data) {
           deferred.resolve(data)
         })
       return deferred.promise
     }
     return service
   })
   
   app.factory('ResourcePost', function ($http, $q) {
     var service = {}
     service.callBack = function ( action, params ) {
       var url = 'http://10.0.10.201:8080/'
       var deferred = $q.defer()
       $http({
         method: 'POST',
         url: url + action,
         data: params,
         headers : {'Content-Type': 'application/json; charset=utf-8'}
       }).success(function (data) {
         deferred.resolve(data)
       })
       return deferred.promise
     }
     return service
   })
   
   app.factory('ResourceDelete', function ($http, $q) {
     var service = {}
     service.callBack = function (action, params) {
        var url = 'http://10.0.10.201:8080/'
        var deferred = $q.defer()
        $http({
            method: 'DELETE',
         //  headers : {'Content-Type': 'application/x-www-form-urlencoded'},
            url: url + action
        }).success(function (data) {
            deferred.resolve(data)
        })
        return deferred.promise
     }
    return service
   })

3. 修改跨域问题

   app.config(['$httpProvider', function($httpProvider) {
      $httpProvider.defaults.withCredentials = true;
   }]);  

4. 获取验证码倒计时

   app.service('WaitSecond',function(){
     var wait = 60;
     var t = this;
     this.waitTime = function(code){
       if(wait == 0){
         $("#"+code).html('获取验证码');
         $("#"+code).removeAttr("disabled");
         wait = 60
       }else{
         console.log(code);
         $("#"+code).html(function(){
           return wait + '秒'
         }).attr('disabled','true');
         wait--;
         setTimeout(function () {
           t.waitTime(code);
         }, 1000);
       }
     }
   })

   html：

   <button id="code" ng-click="register.getCode('code')" class="ng-binding">获取验证码</button>

   controller：

    WaitSecond.waitTime(id);

　　　5.统一接口定义全局变量

app.constant('apiImg','http://10.0.10.200:8080/SeeMeInterface/img/uploadImg')
