python自动化运维一键发送邮箱

Python自动化运维中，使用SMTplib库可以实现发送电子邮件的自动化功能。以下是一个基础的示例，展示如何通过SMTP协议发送一封带有附件的邮件：

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email import encoders
import os

# 邮件设置
sender_email = 'your_email@example.com'
sender_password = 'your_email_password'  # 如果是SMTP应用密码，请使用
receiver_email = 'recipient_email@example.com'
subject = 'Automated Email from Python'
body = 'This is an automated message sent using Python.'
attachment_path = 'path_to_your_attachment'  # 例如 'document.pdf'

# 创建邮件对象
msg = MIMEMultipart()
msg['From'] = sender_email
msg['To'] = receiver_email
msg['Subject'] = subject

# 添加邮件正文
msg.attach(MIMEText(body, 'plain'))

# 添加附件（如果有的话）
with open(attachment_path, 'rb') as f:
    part = MIMEBase('application', 'octet-stream')
    part.set_payload(f.read())
    encoders.encode_base64(part)
    part.add_header('Content-Disposition', 'attachment; filename="{}"'.format(os.path.basename(attachment_path)))
    msg.attach(part)

# 连接SMTP服务器
smtp_server = 'smtp.example.com'  # 根据你的邮箱提供商填写
smtp_port = 587  # 或者465 for SSL/TLS (default for Gmail is 465)

try:
    with smtplib.SMTP(smtp_server, smtp_port) as server:
        server.starttls()  # 如果需要加密连接，添加这行
        server.login(sender_email, sender_password)
        server.sendmail(sender_email, receiver_email, msg.as_string())
        print("Email sent successfully.")
except Exception as e:
    print("Error sending email: ", str(e))

# 关闭连接
server.quit()
