Question

我正在尝试创建一个小脚本，使用gmail通过电子邮件发送多个附件。下面的代码发送电子邮件但不发送附件。预期用途是cron一对db查询并通过电子邮件发送结果。由于报告的date位于文件名中，因此每天总会有2个文件和文件名不同。否则我会使用：

part.add_header('Content-Disposition', 
    'attachment; filename="absolute Path for the file/s"')

非常感谢任何帮助。

import os
import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEImage import MIMEImage
from email.MIMEBase import MIMEBase
from email import Encoders


#Set up crap for the attachments
files = "/tmp/test/dbfiles"
filenames = [os.path.join(files, f) for f in os.listdir(files)]
#print filenames


#Set up users for email
gmail_user = "joe@email.com"
gmail_pwd = "somepasswd"
recipients = ['recipient1','recipient2']

#Create Module
def mail(to, subject, text, attach):
   msg = MIMEMultipart()
   msg['From'] = gmail_user
   msg['To'] = ", ".join(recipients)
   msg['Subject'] = subject

   msg.attach(MIMEText(text))

   mailServer = smtplib.SMTP("smtp.gmail.com", 587)
   mailServer.ehlo()
   mailServer.starttls()
   mailServer.ehlo()
   mailServer.login(gmail_user, gmail_pwd)
   mailServer.sendmail(gmail_user, to, msg.as_string())
   # Should be mailServer.quit(), but that crashes...
   mailServer.close()

#get all the attachments
   for file in filenames:
      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(file))
      msg.attach(part)
#send it
mail(recipients,
   "Todays report",
   "Test email",
   filenames)

Answer 1

在张贴之前应该再等一个小时。做了两个改变：

1。）向上移动附件循环

2。）换掉了 part.add_header（'Content-Disposition'，'attachment; filename =“％s”' ％os.path.basename（file））

for part.add_header（'Content-Disposition'，'attachment; filename =“％s”'％file）

像冠军一样工作。 Gmail包含多个收件人和多个附件。

谢谢@marc！我无法评论你的答案，所以这里有一些修正（错误命名的变量）和小改进：

import os
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email import MIMEImage
from email.mime.base import MIMEBase
from email import Encoders

def mail(to, subject, text, attach):
    # allow either one recipient as string, or multiple as list
    if not isinstance(to,list):
        to = [to]
    # allow either one attachment as string, or multiple as list
    if not isinstance(attach,list):
        attach = [attach]

    gmail_user='username@gmail.com'
    gmail_pwd = "password"
    msg = MIMEMultipart()
    msg['From'] = gmail_user
    msg['To'] = ", ".join(to)
    msg['Subject'] = subject

    msg.attach(MIMEText(text))

    #get all the attachments
    for file in attach:
        print file
        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(file))
        msg.attach(part)

    mailServer = smtplib.SMTP("smtp.gmail.com", 587)
    mailServer.ehlo()
    mailServer.starttls()
    mailServer.ehlo()
    mailServer.login(gmail_user, gmail_pwd)
    mailServer.sendmail(gmail_user, to, msg.as_string())
    # Should be mailServer.quit(), but that crashes...
    mailServer.close()

if __name__ == '__main__':
    mail(['recipient1', 'recipient2'], 'subject', 'body text',
         ['attachment1', 'attachment2'])

我有类似的问题。我可以发送多个附件，但是在我的Mac邮件应用程序上，不会显示所有附件，也不会显示html（在Gmail网络上，一切正常。）如果有人遇到相同的问题，则下面的代码对我来说适用于python3.8。现在，所有附件和html都会显示在邮件应用中。
