android - CacheFactory 在我的浏览器中工作但在我的 apk 中不工作

Question

我已将 Angular 缓存添加到我的应用程序，并创建了我的项目，如下所示:

angular.module('rotaryApp', ["ionic", "angular-cache"])
.run(function($ionicPlatform, CacheFactory) {
$ionicPlatform.ready(function() {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
if(window.cordova && window.cordova.plugins.Keyboard) {
  cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
}
if(window.StatusBar) {
  // org.apache.cordova.statusbar required
  StatusBar.styleDefault();
}
CacheFactory("songsDataCache", { storageMode: "localStorage", maxAge: 360000, deleteOnExpire: "aggressive" });
CacheFactory("versesCache", { storageMode: "localStorage", maxAge: 360000, deleteOnExpire: "aggressive" });
CacheFactory("chorusCache", { storageMode: "localStorage", maxAge: 360000, deleteOnExpire: "aggressive" });
CacheFactory("imageCache", { storageMode: "localStorage", maxAge: 360000, deleteOnExpire: "aggressive" });
CacheFactory("searchCache", { storageMode: "localStorage", maxAge: 360000, deleteOnExpire: "aggressive" });
//CacheFactory("myTeamsCache", { storageMode: "localStorage" });
//CacheFactory("staticCache", { storageMode: "localStorage" });

});})

我的服务如下所示:

(function () {
'use strict';

angular.module('rotaryApp').factory('eliteApi', ['$http', '$q', '$ionicLoading','CacheFactory', eliteApi]);

function eliteApi($http,$q,$ionicLoading,CacheFactory ) {
    var songid;  


   self.songsDataCache = CacheFactory.get("songsDataCache");
   self.versesCache = CacheFactory.get("versesCache");
   self.chorusCache = CacheFactory.get("chorusCache");


    function getLeagues(){
        var defered = $q.defer(),
         cacheKey = "songs",
       songsData = self.songsDataCache.get(cacheKey); 
       if(songsData){

            console.log("found data in cache");
            defered.resolve(songsData);

        } else {

            $ionicLoading.show({template: 'Loading Songs...'})
        var url = "http://bestng.com/notrealurl";
            $http.get(url)
            .success(function (data) {
                 $ionicLoading.hide();
            console.log("Received data via HTTP");
                self.songsDataCache.put(cacheKey, data);
                defered.resolve(data);

            })
            .error(function (data){
                defered.reject();
            });
        }

        return defered.promise;


    }


    function setSongid(sid){
        songid = sid;
    }

    return {
        getLeagues: getLeagues,
        getLeaguesByTitle: getLeaguesByTitle,
        getVerse:getVerse,
        getChorus:getChorus,
        getLeagueData: getLeagueData,
        setSongid: setSongid
    };
};

})();

下面是我的 Controller :

(function () {
'use strict';

angular.module('rotaryApp').controller('LeaguesCtrl', ['$state', 'eliteApi', LeaguesCtrl]);

function LeaguesCtrl($state, eliteApi) {
    var vm = this;

    eliteApi.getLeagues().then(function(data){
        vm.leagues = data;

    });

};

})();

当我不使用“ionic serve”时，getLeagues 函数在我的浏览器中运行良好，但一旦我使用“ionic emulate android”，它就返回一个空白屏幕。请帮助我了解为什么这在我的浏览器中有效但在我的 apk 中无效。

感谢您的宝贵时间。

缓存工厂必须在 ionicPlatform.ready() 之外，但在 run(function(){ ...}) 内声明

将问题中的我的 app.js 与下面的工作 app.js 进行比较:

angular.module('rotaryApp', ["ionic", "angular-cache"])

.run(function($ionicPlatform, CacheFactory) {
  $ionicPlatform.ready(function() {
  // Hide the accessory bar by default (remove this to show the accessory bar     above the keyboard
  // for form inputs)
  if(window.cordova && window.cordova.plugins.Keyboard) {
    cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
  }
  if(window.StatusBar) {
    // org.apache.cordova.statusbar required
    StatusBar.styleDefault();
  }
}); // end of ready()

CacheFactory("songsDataCache", { storageMode: "localStorage", maxAge:    360000, deleteOnExpire: "aggressive" });
CacheFactory("versesCache", { storageMode: "localStorage", maxAge: 360000,  deleteOnExpire: "aggressive" });
CacheFactory("chorusCache", { storageMode: "localStorage", maxAge: 360000,   deleteOnExpire: "aggressive" });
CacheFactory("imageCache", { storageMode: "localStorage", maxAge: 360000, deleteOnExpire: "aggressive" });
CacheFactory("searchCache", { storageMode: "localStorage", maxAge: 360000, deleteOnExpire: "aggressive" });

}); // end of run(function(){..})

这对我有用。我希望它对你也有用
