【Python】如何用Python发送SMTP邮件

【背景】

自动发送邮件通知是流成自动化系统必备的功能，今天介绍如何用Python实现。

【代码】

这里以163邮箱为例

def send_smtp_mail(host="smtp.163.com",content="",cont_type="plain",encode="utf-8",sender_name="My_Robot",reciver_name="user",subject="unkonwn subject",mail_user="myname@163.com",mail_pass="Your Mail Pass" ):
    import smtplib
    from email.mime.text import MIMEText
    from email.header import Header

    with open("param.csv", encoding="utf8") as file:
        mail_addrs = file.readlines()
    sender = 'myname@163.com'
    receivers = [ele.strip() for ele in mail_addrs]

    message = MIMEText(content,cont_type,encode)
    message['From'] = "{}".format(sender)
    message['To'] = ",".join(receivers)
    message['Subject'] = subject

    try:
        smtpObj = smtplib.SMTP_SSL(host,465)
        smtpObj.login(mail_user,mail_pass)
        smtpObj.sendmail(sender,receivers,message.as_string())
        print("mail sent success!")
    except smtplib.SMTPException as e:
        print(e)
