开发一个微信小程序(5)：查询天气-添加未来24小时逐小时天气
在基础实时天气的基础上，展示未来24小时的逐小时天气情况，效果如下
这个功能比较简单，只需要调一下和风天气的24小时预报拿到数据，然后在小程序中使用 <scroll-view> 标签滚动显示数据即可
耗时最长的是调整样式，需要把时间、天气图标、温度、天气描述纵向排列，整了半天才弄好
打开 pages/weather/weather.js，在 queryWeather()方法中添加如下代码，调用24小时天气接口
// 获取locationid后，查询未来24小时天气，在success中发起请求
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
})
},
}); 打开 pages/weather/weather.wxml ，添加滚动显示数据相关代码
<view>
<!-- 未来24小时逐小时天气 -->
<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>
