Python-邮件发送

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

def send_email():
  # 邮件服务器的地址和端口
  smtp_server = 'smtp.qq.com'  # 设置服务器
  smtp_port = 587  # 25 为 SMTP 端口号

# 发件人的邮箱地址/密码和收件人地址
  sender_email = '773203918@qq.com'  # 发件人地址
  sender_password = 'xxx'  # 发件人口令
  recipient_email = '773203918@qq.com'  # 收件人地址

# 构建邮件内容
  subject = '邮件主题'
  body = '邮件正文内容'
  # html页面内容
  # body = F'''
  #   <p>Godlike_{<引用的变量名称>} 帐号登录失败</p>
  #   <p>访问 <a href='https://panel.godlike.host/'>Godlike</a> 重新获取cookie</p>
  # '''

# 创建一个 MIMEMultipart 对象
  msg = MIMEMultipart()
  msg['From'] = sender_email
  msg['To'] = recipient_email
  msg['Subject'] = subject

# 将正文内容添加到邮件中(plain=文本内容,html=页面)
  msg.attach(MIMEText(body, 'plain', 'utf-8'))
  # msg.attach(MIMEText(body, 'html', 'utf-8'))

try:
    server = smtplib.SMTP(smtp_server, smtp_port)  # 连接到邮件服务器
    server.starttls()  # 使用 TLS 加密通信
    server.login(sender_email, sender_password)  # 登录到邮箱
    server.sendmail(sender_email, recipient_email, msg.as_string())  # 发送邮件
    server.quit()  # 关闭连接
    print('邮件发送成功!')
  except Exception as e:
    print(f'邮件发送失败: {str(e)}')
if __name__ == "__main__":
  send_email()
```
