我爲移動應用程序的項目工作,並且在商店中使用代理檢索信息時遇到問題。 這是一個管理火車站的應用程序,對於一個車站,我調用一個WebService來檢索10個下一班列車(在json中)。Sencha touch 2:通過代理在商店中檢索信息

我有2類,TrainStation(火車站在法國))與列車

在火車站的方法來檢索火車:

getListTrains: function(TR3A) { 
    console.log('plop'); 
    var trains = Ext.create('Ext.data.Store', { 
     model: 'Train', 
     proxy: { 
      type: 'ajax', 
      url: 'http://eclernet-mobile.dev.dsit-hp.sncf.fr/Trainservice.svc/GetListTrainsAtGare/'+TR3A, 
      method: 'POST', 
      headers: { 
       'Accept': 'application/json' 
      }, 
      reader: { 
       type: 'json' 
      } 
     } 
    }); 

    console.log(trains); 
} 

類列車(其延伸模型使用該方法):

Ext.define('Train', { 
extend: 'Ext.data.Model', 
config: { 
    codeMission: null,  
    numero: null, 
    sens: null,  
    dessertes: null,  
    voie: null, 
    heureProbable: null,   
    heureTheorique: null, 
    voiePrecedente: null, 
    quai: null, 
    retard: null 
}, 


constructor: function(config) { 
    this.initConfig(config);  
}, 

});

當我打電話給我的方法與有效的火車站,我的console.log(火車);檢索一個空對象...

我的JSON:
