如何使用 python 发送带有多个附件的电子邮件

Question

I can't get this to attach multiple documents to an email. It attaches the first document and then sends the document. I am a noob when it comes to using the auto-email function. Could anyone explain this or show me how to fix this?

    self.name = name
    fromaddr = "Your Email"
    toaddr = "Sending Email"
    msg = MIMEMultipart()
    #email address
    msg['From'] = fromaddr
    # Receivers email address
    msg['To'] = toaddr
    #subject
    msg['Subject'] = ' Weekly Report'
    #body of the mail
    body = 'Hey, I\'m testing the automated email function, let me know if you get it and how does it look!'
    #msg instance
    msg.attach(MIMEText(body, 'plain'))
    # open the file to be sent
    a = 0
    for i in self.name:
        while a < len(self.name):
            filename = i + '.pdf'
            attachment = open(i + '.pdf', "rb")
            a+=1
            print(len(self.name))
            print(a)
    p = MIMEBase('application', 'octet-stream')
    p.set_payload((attachment).read())
    encoders.encode_base64(p)
    p.add_header('Content-Disposition', "attachment; filename= %s" % filename)
    msg.attach(p)
    s = smtplib.SMTP('smtp.gmail.com', 587)
    s.starttls()
    s.login(fromaddr, "password")
    text = msg.as_string()
    s.sendmail(fromaddr, toaddr, text)
    s.quit()

Try this (Reference:- https://dzone.com/articles/send-email-attachments-python )

import smtplib
import os
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders

def send_mail(send_from, send_to, subject, text, files=[], server="localhost"):
  assert type(send_to)==list
  assert type(files)==list

  msg = MIMEMultipart()
  msg['From'] = send_from
  msg['To'] = COMMASPACE.join(send_to)
  msg['Date'] = formatdate(localtime=True)
  msg['Subject'] = subject

  msg.attach( MIMEText(text) )

  for f in files:
    part = MIMEBase('application', "octet-stream")
    part.set_payload( open(file,"rb").read() )
    Encoders.encode_base64(part)
    part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(f))
    msg.attach(part)

  smtp = smtplib.SMTP(server)
  smtp.sendmail(send_from, send_to, msg.as_string())
  smtp.close()
