AngularJS基于provider实现全局变量的读取和赋值方法

'use strict';
/ App Module /
var test2 = 'tank';     //方法1，定义全局变量
var phonecatApp = angular.module('phonecatApp', [   //定义一个ng-app
 'ngRoute',
 'phonecatControllers',
 'tanktest'
]);
phonecatApp.value('test',{"test":"test222","test1":"test111"}); //方法2定义全局变量
phonecatApp.constant('constanttest', 'this is constanttest');  //方法3定义全局变量

'use strict';
/ Controllers /
var phonecatControllers = angular.module('phonecatControllers', []);
phonecatControllers.controller('PhoneListCtrl', ['$scope','test','constanttest',
 function($scope,test,constanttest) {
  $scope.test = test;          //方法2，将全局变量赋值给$scope.test
  $scope.constanttest = constanttest;  //方法3，赋值
  $scope.test2 = test2;         //方法1，赋值
 }]);

<script type="text/javascript">
    var app = angular.module('ngRouteWxCtb', ['ngRoute','ngCookies']);
    //TODO:provider of globle uid and weixinIsInit param
    app.provider('userService', function () {
      var data = {uid:0,weixinIsInit:false};
      var f = function (uid,weixinIsInit) {
        if (uid != 0)
        {
          data.uid= uid;
          data.weixinIsInit = weixinIsInit;
        }
        return data;
      };
      this.$get = function () {
        return f;
      };
    });
</script>

app.controller('myCtrl1', function ($scope, userService) {
  var data = userService(0, 0, false);//读取全局变量
}));
app.controller('myCtrl2', function ($scope, userService) {
  var data = userService(123, 111, true);//设置全局变量
}));
