Introduction

最近突發奇想, 想定時發送郵件, 最終選擇了js這套方案, 真是有趣!

但是前端這一行, 自身這審美, 這一點一點肝, 真是幹不了😪

項目總體分為

這兩部分.

思路是 請求 天氣API, 彩虹屁API, 圖床 的資料放入 模闆html( template.js) 中, 傳回一個HTML字元串, 再将這個字元串用 nodemailer 發送給收件人.

使用 schedule 在每天19.19定時發送

TIPS:

• QQ郵箱需要收件人添加信任才能看到圖檔!
• 代碼塊中的pass是郵箱授權碼, 而非QQ密碼!

Code

title, emoji 等這些都是自定義庫, 分子產品來寫, 日後若要再增添功能也友善!
