加附件的部分我这边为什么显示说name 'MIMEMultipart' is not defined啊，也就是上面的代码啊， from email import encoders from email.header import Header from email.mime.text import MIMEText from email.utils import parseaddr, formataddr

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: ') to_addr = input('To: ') smtp_server = input('SMTP server: ')

#邮件对象 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()

#邮件正文 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('/F/Python/123.jpg','rb') as f:

#设置福建的MIME和文件名，这里是jpg类型
mime=MIMEBase('image','jpg',filename='123.jpg')
#加上必要的头信息
mime.add_header('Content-Disposition','attachment',filename='123.jpg')
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()
