# 添加邮件附件即添加一个MIMEBase
with open('test.png', 'rb') as f:
    # 附件的类型为图片，且为png类型文件， 附件名为test.png
    mime = MIMEBase('image', 'png', filename='test.png')
    # 必要的头信息
    mime.add_header('Content-Disposition', 'attachment', filename='test.png')
    mime.add_header('Content-ID', '<0>')
    mime.add_header('X-Attachment-ID', '0')
    # 将须要的附件的内容加载进mine
    mime.set_payload(f.read())
    # 编码类型为base64
    encoders.encode_base64(mime)
    # 将MIMEBase对象mime链接进MIMEMultipart
    msg.attach(mime)
    
# 设置SMTP服务器地址和端口
server = smtplib.SMTP(smtp_server, int(smtp_server_port))
# 用STARTTlS方式加密SMTP
server.starttls()
# 打印出和SMTP服务器交互的全部信息
server.set_debuglevel(1)# 登陆帐户
server.login(from_addr, password)# 发送邮件， as_string把对象转化为str
server.sendmail(from_addr, [to_addr], msg.as_string())
server.quit()
