python利用smtplib实现QQ邮箱发送邮件

from smtplib import SMTP_SSL 
from email.mime.text import MIMEText 
from email.header import Header 
 
email_from = "123456@qq.com" #改为自己的发送邮箱 
email_to = "654321@qq.com" #接收邮箱 
hostname = "smtp.qq.com" #不变，QQ邮箱的smtp服务器地址 
login = "123456@qq.com" #发送邮箱的用户名 
password = "xddflpwqesfkbidf" #发送邮箱的密码，即开启smtp服务得到的授权码。注：不是QQ密码。 
subject = "python+smtp" #邮件主题 
text = "send email" #邮件正文内容 
 
smtp = SMTP_SSL(hostname)#SMTP_SSL默认使用465端口 
smtp.login(login, password) 
 
msg = MIMEText(text, "plain", "utf-8") 
msg["Subject"] = Header(subject, "utf-8") 
msg["from"] = email_from 
msg["to"] = email_to 
 
smtp.sendmail(email_from, email_to, msg.as_string()) 
smtp.quit()
