前言
最近在学小程序开发,刚好学到天气预报功能的制作,于是给大家分享下。
效果图
天气API获取
这里我用的是和风天气的API，打开官网注册或者登陆你的账号
进入控制台,新建应用
这是刚刚我们创建好的应用，点击添加KEY
选择WebAPI
这注册好我们的API了
微信小程序后台域名配置
登陆小程序后台，分别点击开发和开发设置
点击修改，将我们API的域名添加到request合法域名里面https://free-api.heweather.net

注意问题（必看）
由于我的项目有用到天气预报的逐小时预报和7天预报，和风天气又必须实名才能获取到此数据，所以请登录和风天气后台进行实名认证
到此这篇关于微信小程序实现天气预报功能(附源码)的文章就介绍到这了,更多相关小程序实现天气预报内容请搜索服务器之家以前的文章或继续浏览下面的相关文章希望大家以后多多支持服务器之家！
