小程序怎么在前端接受不到后臺傳回來的JSON數(shù)據(jù)

onShow:?function?()?{var?that?=?this;wx.request({url:?"http://localhost:8082/demo/listArea",method:?"GET",data:?{},sucess:?function(res){var?list?=?res.data.areaList;if(list?==?null){var?toastText?=?'獲取數(shù)據(jù)失敗'?+?res.data.errMsg;wx.showToast({title:?toastText,icon:'',duration:?2000});}?else?{that.setData({list:list});}}})},

data:?{list:[]},

<block?wx:for="{{list}}"><view?class="widget"><text?class="column">{{item.areaId}}</text><text?class="column">{{item.areaName}}</text><text?class="column">{{item.priority}}</text><text?class="link-column"><navigator?class="link"?url="../demo/getareaId?areaId={{item.areaId}}">編輯</navigator><text?class="link"?bindtap="deleteArea"?data-areaid="{{item.areaId}}"data-areaname="{{item.areaName}}"?data-index="{{index}}">刪除</text></text></view></block>

public?Map<String,?Object>?listArea(){		Map<String,?Object>?modelMap?=?new?HashMap<>();		List<Area>?list?=?areaService.queryArea();		modelMap.put("areaList",?list);		return?modelMap;	}
