【uni-app】使用天气API做一个天气APP（全过程）- 实况、逐小时、40日

Cc琎2024-08-17 20:36

头一次使用uni-app写代码, 现学现卖, 写的不好的地方见谅, 申请个appid就可以运行

切换城市界面比较简单, 城市名称需要符合天气api参数规则, 录入的城市不要带市区县; 格式如: 青岛、铁西、海淀、沛县

APP效果

功能说明

  1. 实况天气
  2. 逐小时预报
  3. 未来7日天气
  4. 未来40日天气
  5. 空气质量详情
  6. 切换城市
  7. 更多功能开发中

开发准备

  1. 前往天气api接口官网 http://tianqiapi.com 注册账号, 进入用户中心获取appid和appsecret
  2. 修改App.vue下globalData字段内容
javascript 复制代码 
globalData:{
	appid : '你的appid',
	appsecret : '你的appsecret'
},
  1. 然后直接运行程序就 o了

代码下载

先贴上下载链接, 省的在最底下看不见
http://file.tianqiapi.com/uniapp_tianqi0802.zip

附完整代码

  1. 首页 > index.vue
  2. 40日预报 > month.vue
  3. 空气质量详情 > aqi.vue
  4. 切换城市 > city.vue

首页 > index.vue
