开发一个微信小程序(6)：查询天气添加最近3日天气

在原有基础上添加未来3日天气，效果如下

这里需要调一下和风天气未来3日天气接口，然后再调整下前端样式

1、后端代码

编辑 pages/weather/weather.js，添加调用接口的js代码

               // 获取locationid后，查询未来3天气，在success中发起请求
                  wx.request({
                    url: 'https://devapi.qweather.com/v7/weather/3d', 
                    method: 'GET',
                    data: {
                      key: this.data.key,
                      location: location_id
                    },
                    success: (res) => {
                      console.log(res);
                      this.setData({
                        future: res.data.daily,
                        flag: true
                      })
                    },
         
                  });

2、前端代码

编辑 pages/weather/weather.wxml，添加最近3日天气相关代码

<view class="title"><text>最近3日天气</text></view>
  <view class="future-3d-father">
    <view class="future-3d-son1">
        <view><text>{{future[0].fxDate}}</text></view>
        <view><image wx:if="{{future[0].iconDay}}" src="../../QWeather-Icons-1.1.1/icons/{{future[0].iconDay}}.svg"></image></view>
        <view><text space="nbsp">{{future[0].tempMin}}/{{future[0].tempMax}} ℃</text></view>
        <view style="margin-top: 15rpx;"><text space="nbsp">{{future[0].textDay}}</text></view>
    </view>
    <view class="future-3d-son2">
      <view><text>{{future[1].fxDate}}</text></view>
      <view><image wx:if="{{future[1].iconDay}}" src="../../QWeather-Icons-1.1.1/icons/{{future[1].iconDay}}.svg"></image></view>
      <view><text space="nbsp">{{future[0].tempMin}}/{{future[1].tempMax}} ℃</text></view>
      <view style="margin-top: 15rpx;"><text space="nbsp">{{future[1].textDay}}</text></view>
    </view>
    <view class="future-3d-son3">
      <view><text>{{future[2].fxDate}}</text></view>
      <view><image wx:if="{{future[2].iconDay}}" src="../../QWeather-Icons-1.1.1/icons/{{future[2].iconDay}}.svg"></image></view>
      <view><text space="nbsp">{{future[0].tempMin}}/{{future[2].tempMax}} ℃</text></view>
      <view style="margin-top: 15rpx;"><text space="nbsp">{{future[2].textDay}}</text></view>
    </view>
  </view>
