没有使用Python示例发送电子邮件

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

# 创建邮件对象
msg = MIMEMultipart()
msg['From'] = 'sender@example.com'
msg['To'] = 'receiver@example.com'
msg['Subject'] = 'Test Email'

# 添加邮件正文
body = 'This is a test email.'
msg.attach(MIMEText(body, 'plain'))

# 连接SMTP服务器并发送邮件
smtp_server = 'smtp.example.com'
smtp_port = 587
smtp_user = 'username'
smtp_password = 'password'

server = smtplib.SMTP(smtp_server, smtp_port)
server.starttls()
server.login(smtp_user, smtp_password)
server.sendmail('sender@example.com', 'receiver@example.com', msg.as_string())
server.quit()
