Python利用脚本实现自动发送电子邮件

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders

def send_email(sender_email, sender_password, receiver_email, subject, body, attachment_path):
    # 设置SMTP服务器
    smtp_server = 'smtp.example.com'  # 替换为你的SMTP服务器地址
    smtp_port = 587  # 替换为你的SMTP服务器端口

    # 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
    if attachment_path:
        attachment = open(attachment_path, 'rb')
        part = MIMEBase('application', 'octet-stream')
        part.set_payload(attachment.read())
        encoders.encode_base64(part)
        part.add_header('Content-Disposition', f'attachment; filename={attachment_path}')
        msg.attach(part)
        attachment.close()

    # 连接SMTP服务器并发送邮件
    try:
        server = smtplib.SMTP(smtp_server, smtp_port)
        server.starttls()  # 启用TLS加密
        server.login(sender_email, sender_password)
        text = msg.as_string()
        server.sendmail(sender_email, receiver_email, text)
        server.quit()
        print("邮件发送成功")
    except Exception as e:
        print(f"邮件发送失败: {e}")

if __name__ == "__main__":
    # 替换为你的发件人邮箱和密码
    sender_email = 'your_email@example.com'
    sender_password = 'your_password'

    # 替换为收件人邮箱
    receiver_email = 'receiver_email@example.com'

    # 邮件主题和正文
    subject = '测试邮件'
    body = '这是一封测试邮件，包含附件。'

    # 附件路径（可选）
    attachment_path = 'example.txt'  # 替换为你的附件文件路径

    # 发送邮件
    send_email(sender_email, sender_password, receiver_email, subject, body, attachment_path)
