開發一個微信小程序(5)：查詢天氣-添加未來24小時逐小時天氣

在基礎實時天氣的基礎上，展示未來24小時的逐小時天氣情況，效果如下

這個功能比較簡單，只需要調一下和風天氣的24小時預報拿到數據，然後在小程序中使用 <scroll-view> 標籤滾動顯示數據即可

耗時最長的是調整樣式，需要把時間、天氣圖標、溫度、天氣描述縱向排列，整了半天才弄好

打開  pages/weather/weather.js，在 queryWeather()方法中添加如下代碼，調用24小時天氣接口

// 獲取locationid後，查詢未來24小時天氣，在success中發起請求
                  wx.request({
                    url: 'https://devapi.qweather.com/v7/weather/24h', 
                    method: 'GET',
                    data: {
                      key: this.data.key,
                      location: location_id
                    },
                    success: (res) => {
                      console.log(res);
                      this.setData({
                        twenty_four: res.data.hourly,
                        flag: true
                      })
                    },
         
                  });

 打開 pages/weather/weather.wxml ，添加滾動顯示數據相關代碼

<view>
      <!-- 未來24小時逐小時天氣 -->
      <scroll-view scroll-x="true" class="next">
          <view wx:for="{{twenty_four}}" wx:key="index" class="next-son">
            <view><text>{{tools.splitdaily(item.fxTime)}}</text></view>
            <view><image wx:if="{{item.icon}}" src="../../QWeather-Icons-1.1.1/icons/{{item.icon}}.svg"></image></view>
            <view><text space="nbsp">{{item.temp}} ℃</text></view>
            <view style="margin-top: 15rpx;"><text space="nbsp">{{item.text}}</text></view>
          </view>
      </scroll-view>
  </view>
</view>
