我是EXTJS的新手,有问题,这是我的商店

someStore = new Ext.data.JsonStore({

    root: 'results',
    proxy: new My.HttpProxy({
        url: '/cityList',
        method: 'POST'
    }),
    fields: ['id','name']
});

当我得到并且我需要通过id someStore.reload({params:{someId:someId}})重新加载商店;

如果我使用Ext.data.HttpProxy,它的工作正常,但我需要捕获302并做一些处理它,

My.Ajax = {

    proxyRequest: function(o){
        this.cbOutSide = o.callback;
        o.callback = this.cb;
        Ext.Ajax.request(o);
    }...
    cb: function(options, success, response) {
            ....
      if (response.status == 200) {
          var resObj = Ext.util.JSON.decode(response.responseText);
          this.cbOutSide(resObj);
      }     
      if (response.status == 302) {
          Ext.Msg.show({title: '...',msg: 'Time OUT!', 
             buttons: Ext.Msg.OK, icon: Ext.MessageBox.ERROR});
      }  
   }
};  

并且

My.HttpProxy = Ext.extend( Ext.data.HttpProxy, {

    doRequest : function(action, rs, params, reader, cb, …
