前言
最近在學小程序開發(fā),剛好學到天氣預報功能的制作,于是給大家分享下。
效果圖
天氣API獲取
這里我用的是和風天氣的API，打開官網(wǎng)注冊或者登陸你的賬號
進入控制臺,新建應用
這是剛剛我們創(chuàng)建好的應用，點擊添加KEY
選擇WebAPI
這注冊好我們的API了
微信小程序后臺域名配置
登陸小程序后臺，分別點擊開發(fā)和開發(fā)設置
點擊修改，將我們API的域名添加到request合法域名里面https://free-api.heweather.net

注意問題（必看）
由于我的項目有用到天氣預報的逐小時預報和7天預報，和風天氣又必須實名才能獲取到此數(shù)據(jù)，所以請登錄和風天氣后臺進行實名認證
到此這篇關于微信小程序實現(xiàn)天氣預報功能(附源碼)的文章就介紹到這了,更多相關小程序實現(xiàn)天氣預報內容請搜索服務器之家以前的文章或繼續(xù)瀏覽下面的相關文章希望大家以后多多支持服務器之家！
