实现原理

采用高德地图微信小程序开发API(getWeather),如果 city 属性的值为空(或者没有city属性),默认返回定位位置的天气数据;如果 city 不为空,则返回 city 指定位置的天气数据。

WXML

<view class="map-weather">
  <view><text>城市:</text>{{address}}</view>
  <view><text>天气:</text>{{weather}}</view>
  <view><text>温度:</text>{{temperature}}℃</view>
  <view><text>风力:</text>{{windpower}}级</view>
  <view><text>湿度:</text>{{humidity}}%</view>
  <view><text>风向:</text>{{winddirection}}</view>
</view>

JS

const app = getApp();
const amap = app.data.amap;
const key = app.data.key;
Page({
  data: {

    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
          })
        }
