    1
    MIMEMultipart('related')

    • 编写html格式内容包含图片信息

      1
      2
      msgHtmlImg = '<img src="cid:image{count}"><br>'
      MIMEText(msgHtmlImg, 'html')

    • 读取图片并添加邮件头

      fp = open(imgpath, 'rb')
      msgImage = MIMEImage(fp.read())
      fp.close()
       
      # Define the image's ID as referenced above
      msgImage.add_header('Content-ID', '<image{count}>'.format(count=i))
      msgRoot.attach(msgImage)
