python 发送带附件邮件 脚本

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

-- coding: UTF-8 --

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

from_addr = "xxx"
password ="xxx"
to_addr =["xx"]
smtp_server = "mail.xxx.com"

msg = MIMEMultipart()
msg.attach(MIMEText('send with file...', 'plain', 'utf-8'))
msg['From'] =_format_addr(from_addr)
msg['To'] = _format_addr(to_addr)
msg['Subject'] = Header(u'来自SMTP的问候……', 'utf-8')

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

添加附件就是加上一个MIMEBase，从本地读取一个图片:

with open('jietu.png', 'rb') as f:
# 设置附件的MIME和文件名，这里是png类型:
mime = MIMEBase('image', 'png', filename='jietu.png')
# 加上必要的头信息:
mime.add_header('Content-Disposition', 'attachment', filename='jietu.png')
mime.add_header('Content-ID', '<0>')
mime.add_header('X-Attachment-Id', '0')
# 把附件的内容读进来:
mime.set_payload(f.read())
# 用Base64编码:
encoders.encode_base64(mime)
# 添加到MIMEMultipart:
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()
