Introduction

最近突发奇想, 想定时发送邮件, 最终选择了js这套方案, 真是有趣!

但是前端这一行, 自身这审美, 这一点一点肝, 真是干不了😪

项目总体分为

这两部分.

思路是 请求 天气API, 彩虹屁API, 图床 的数据放入 模板html( template.js) 中, 返回一个HTML字符串, 再将这个字符串用 nodemailer 发送给收件人.

使用 schedule 在每天19.19定时发送

TIPS:

• QQ邮箱需要收件人添加信任才能看到图片!
• 代码块中的pass是邮箱授权码, 而非QQ密码!

Code

title, emoji 等这些都是自定义库, 分模块来写, 日后若要再增添功能也方便!
