Python :通过SMTP发送html格式的电子邮件

import smtplib
from email.mime.text import MIMEText
from email.header import Header

# 创建一个MIMEText对象，指定邮件内容和类型（html）
message = MIMEText('<h1>Hello, World!</h1>', 'html', 'utf-8')

# 设置邮件主题
message['Subject'] = Header('Python SMTP邮件测试', 'utf-8')

# 设置发件人
message['From'] = Header('sender@example.com', 'utf-8')

# 设置收件人
message['To'] = Header('receiver@example.com', 'utf-8')

# 连接SMTP服务器
smtp_server = 'smtp.example.com'
smtp_port = 25
smtp_username = 'username'
smtp_password = 'password'
smtp = smtplib.SMTP(smtp_server, smtp_port)
smtp.login(smtp_username, smtp_password)

# 发送邮件
smtp.sendmail(smtp_username, ['receiver@example.com'], message.as_string())

# 关闭连接
smtp.quit()
