python3.7发送邮件

 

python升级至3.7版本之后,之前的发送邮件函数报错。查找原因后发现在新版本中,SMTP建立连接阶段就要指明host地址,而之前是不需要的。

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


def send_mail(title, message, receiver, attach_file=''):

    # 建立连接
    # python3.7版本开始,在SMTP建立阶段就要指明host地址,3.7之前不需要
    s = smtplib.SMTP(host='host')
    s.connect(host='host', port='port')

    # 网站需要安全认证时添加
    s.starttls()

    # 登录发送邮件账户
    s.login('username', 'password')

    msg = MIMEMultipart()

    content = MIMEText(message, 'html', 'utf-8')
    msg['Subject'] = f'{title}'
    msg['From'] = 'sender'
    msg['To'] = receiver
    msg.attach(content)

    if attach_file:
        att1 = MIMEText(open(attach_file, 'rb').read(), 'base64', 'utf-8')
        att1['Content-Type'] = 'application/octet-stream'
        att1['Content-Disposition'] = 'attachment; filename="report.txt"'
        msg.attach(att1)

    try:
        s.send_message(msg)
        status = 'Success'
        print(status)
    except smtplib.SMTPException as e:
        print(e)
        status = 'Failed'

    s.quit()

    return status

if __name__ == '__main__':
    send_mail('title', 'msg', 'receiver', 'attachment')
