python 使用smtplib发送带附件的email

昨天搞了好久看了好多版本的可以添加附件的python程序，到我这里就是不行，今天继续搞

终于，在不断尝试和借鉴中 竟然成功了。

import smtplib, mimetypes  
from email.mime.text import MIMEText  
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart  


msg=MIMEMultipart()
msg["From"] = "[e-mail]"
msg["To"] = "[e-mail]"
msg["Subject"] = "Test email"


text=MIMEText("This is text content.")
msg.attach(text)


filename=r'D:\Downloads\1.zip'
ctype,encoding = mimetypes.guess_type(filename)
if ctype is None or encoding is not None:
    ctype='application/octet-stream'
maintype,subtype = ctype.split('/',1)


#att=MIMEImage(open(filename,'r').read(),subtype)
att=MIMEImage(open(filename, 'rb').read(),subtype)
print(ctype,encoding)
att["Content-Disposition"] = 'attachmemt;filename="1.zip"'
msg.attach(att)


smtp=smtplib.SMTP('smtp.126.com')
smtp.login('[e-mail]','password‘)
smtp.sendmail(msg["From"],msg["To"],msg.as_string())
