Python脚本自动发送电子邮件

要编写一个Python脚本来自动发送电子邮件，你可以使用smtplib库来处理SMTP协议，以及email库来构建邮件内容。

安装必要的库
通常情况下，smtplib和email库是Python标准库的一部分，因此不需要额外安装。如果你使用的是较旧的Python版本，可能需要确保这些库已安装。
编写脚本
以下是一个完整的Python脚本示例，用于发送带有附件的电子邮件

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encodersdef 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_emailmsg['To'] = receiver_emailmsg['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)
