微信小程序使用map组件实现获取定位城市天气或者指定城市天气数据功能

 城市：{{address}}
 天气：{{weather}}
 温度：{{temperature}}℃
 风力：{{windpower}}级
 湿度：{{humidity}}%
 风向：{{winddirection}}

const app = getApp();
const amap = app.data.amap;
const key = app.data.key;
Page({
 data: {
 address:'',
 weather:'',
 temperature:'',
 humidity:'',
 windpower:'',
 winddirection:''
 },
 onLoad(){
 var _this = this;
 var myAmap = new amap.AMapWX({ key: key });
 myAmap.getWeather({
  type: 'live',
  success(data) {
  if(data.city){
   _this.setData({
   address: data.liveData.city,
   humidity: data.liveData.humidity,
   temperature: data.liveData.temperature,
   weather: data.liveData.weather,
   winddirection: data.liveData.winddirection,
   windpower: data.liveData.windpower
   })
  }
  },
  fail() {
  wx.showToast({ title: '失败！' })
  }
 })
 }
})

page{
 width: 100%;
 height: 100%;
 background-color: lightseagreen;
 color:#fff;
}
.map-weather{
 position: fixed;

 transform: translateY(-50%) translateX(-50%);
}
.map-weather view{
