我为一个移动应用程序项目工作，并且在商店中使用代理检索信息时遇到问题。这是一个管理火车站的应用程序，对于一个火车站，我调用了一个 WebService 来检索接下来的 10 列火车（在 json 中）。
我有 2 节课，TrainStation（法语中的 Gare；））和 Train
Gare 中检索火车的方法：
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);
}
Train 类（将 Model 扩展为使用该方法）：
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);
},
});
当我使用有效的火车站调用我的方法时，我的 console.log(trains); 检索一个空对象...
