python 发送邮件

# -*- coding: utf-8 -*-

from email import encoders
from email.header import Header
from email.mime.text import MIMEText
from email.utils  import parseaddr, formataddr
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase

import smtplib

def _format_addr(s):
    name, addr = parseaddr(s)
    return formataddr((Header(name, 'utf-8').encode(), addr))

from_addr = input('From:')
password = input('Password:') # 这里填写授权码（163邮箱是这样的）
to_addr = input('To:')
smtp_server = input('SMTP server:')

#msg = MIMEText('hello, send by Python...', 'plain', 'utf-8')
msg = MIMEMultipart()
msg['From'] = _format_addr('Python爱好者 <%s>' % from_addr)
msg['To'] = _format_addr('管理员 <%s>' % to_addr)
msg['Subject'] = Header('来自SMTP的问候....', 'utf-8').encode()


msg.attach(MIMEText('send with file...', 'plain', 'utf-8'))

with open('0.png', 'rb') as f:
    mime = MIMEBase('image', 'png', filename='0.png')
    mime.add_header('Content-Disposition', 'attachment', filename='0.png')
    mime.add_header('Content-ID','<0>')
    mime.add_header('X-Attachment-Id', '0')
    mime.set_payload(f.read())
    encoders.encode_base64(mime)
    msg.attach(mime)

server = smtplib.SMTP(smtp_server, 25)
server.set_debuglevel(1)
server.login(from_addr, password)
server.sendmail(from_addr, [to_addr], msg.as_string())
server.quit()

测试结果如下：

控制台跑的程序，然后去163邮箱发件箱里，出现了发送的邮件信息，

qq邮箱的收件箱里出现了收件信息，

（完）
