微信小程序天气预报功能实现(支持自动定位,附源码)
目录
前言
天气API获取
微信小程序后台域名配置
页面代码
注意问题（必看）
源码
总结
前言由于和风天气API的更新，之前写的那篇文章 可能会出现版本不兼容的 情况。所以 更新了 这个 使用新版API的 小程序。
效果图
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,选择应用管理,新建应用（应用版本 选择 免费开发版，key的类型 选择 Web API）
创建成功后就可以看到 待会要用到的 key了
登陆小程序后台，分别点击开发和开发设置
点击修改，将我们要用到的 API的域名添加到request合法域名里面，https://devapi.qweather.com 和 https://geoapi.qweather.com 。

注意问题（必看）
为了确保 小程序 可以 正常使用，请先在和风天气 控制台 升级为 个人开发者（ps:该升级需要上传实名信息）。
在js代码中，请将刚刚申请的key 填写进 APIKEY 里面
Gitee源码 （欢迎Start）
