这篇文章主要讲解了“微信小程序天气预报功能怎么实现”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“微信小程序天气预报功能怎么实现”吧！
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
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，将我们要用到的 API的域名添加到request合法域名里面

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
