EMAIL_ADDRESSS =  "xxx@126.com"
EMAIL_PASSWORD = "xxx"   #邮箱smtp授权码

with smtplib.SMTP('smtp.126.com',25) as smtp:
    
    smtp.login(EMAIL_ADDRESSS,EMAIL_PASSWORD)
    
    subject = 'grab dinner this weekend?'
    body = 'how about dinner at 7pm this saturday?'
    
    msg = f'Subject:{subject}\n\n{body}'
    
    smtp.sendmail(EMAIL_ADDRESSS,'xxx@126.com',msg)

3. email.message使用

如何给html邮件文件中添加图片

1. 相关依赖库

目前采用的式python2发邮件的库，python3发送邮件方式相对要简化了一些，但是还没有弄懂，感兴趣的同学可以探索以下

相关库文件

  • smtplib
  • asyncio
  • MIMEImage
  • MIMEMultipart
  • MIMEText
  • Header
  • pyppeteer

2. 代码思路

graph TD
A[import libraries]-->B[获取待发送信息材料]
B-->C[html信息]
B--pyppeteer-->D[打开网页并截图工具截取图片]
D--asyncio-->C
C--smtp-->E[发送信息]

注释： Mermaid(美人鱼)图的编写可参考简书此文 1
