python3利用smtplib发送、抄送邮件并附带附件

1. 导包

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import logging

2. 定义发送邮件函数

def send_mail(MAIL_SERVER, MAIL_USERNAME, MAIL_PASSWORD, accept_list, Cc_list, SUBJECT, text, file_name):
	
	message = MIMEMultipart()
	message['From'] = MAIL_USERNAME  # 发件人
	message['To'] = ";".join(accept_list)  # 收件人，将列表转换为字符串
	message["Cc"] = ";".join(Cc_list)  # 抄送人，将列表转换为字符串
	message['Subject'] = SUBJECT  # 邮件主题
	message.attach(MIMEText(text, 'plain', 'utf-8'))  # 格式化邮件内容，编码为utf-8

	att1 = MIMEText(open(file_name, 'rb').read(), 'base64', 'utf-8')  # 添加附件
	att1["Content-Type"] = 'application/octet-stream'  # 设置类型
	att1["Content-Disposition"] = 'attachment; filename="{0}"'.format("test.xlsx")  # 设置邮件用现实的名称
	message.attach(att1)

	try:
		mailServer = smtplib.SMTP(MAIL_SERVER, 25)  # 25为端口号(邮件）
		# 登录邮箱
		mailServer.login(MAIL_USERNAME, MAIL_PASSWORD)  # 需要的是，邮箱的地址和授权密码
		# 发送文件
		mailServer.sendmail(MAIL_USERNAME, accept_list + Cc_list, message.as_string())
		mailServer.close()    # 关闭连接
		return True
	except Exception as e:
		# logging.debug(e)
		print(e)
		return False

3. 调用发送邮件函数

def main():

	MAIL_SERVER = 'smtp.qq.com'  # smtp服务器
	MAIL_USERNAME = '*****@qq.com'  # 发件人
	MAIL_PASSWORD = '**********'  # 发送者授权码
	accept_list = ['****@163.com', '*****@qq.com']  # 收件人
	Cc_list = ['*****@qq.com', '*****@qq.com']  # 抄送人
	SUBJECT = "send mail test"  # 主题
	text = "test page"  # 内容
	file_name = "a.xlsx"  # 上传附件名称(当前路径)

	if send_mail(MAIL_SERVER, MAIL_USERNAME, MAIL_PASSWORD, accept_list, Cc_list, SUBJECT, text, file_name):
		logging.debug("Send mail succed!")

	else:
		logging.debug("Send mail failed")


if __name__ == '__main__':
	main()
