将对象之类的文件附加到电子邮件python 3 [英] attach file like object to email python 3

问题描述

我在网上找到了很多关于如何将本地文件附加到电子邮件的示例.我想要做的是将像对象这样的文件附加到电子邮件中.你为什么问?所以我不必处理清理文件.下面是我的代码和我的错误.经过大量的谷歌搜索，我仍然没有设法让它工作，任何帮助将不胜感激:)

I have found a lot of examples on the net of how to attach local files to an email. What I want to do is attach a file like object to an email. Why you ask? so I don't have to deal with cleaning up files. Below is my code and my error. After much googling I still have not managed to get it to work, any help would be greatly appreciated :)

def email_sup_teams(team_name, contact_list, file_attachemnt):
    message_list = []
    for jobs in file_attachemnt:
        for k, v in jobs.items():
            message_list.append(v + ',')
    attachment_text = "
".join(message_list)
    print(type(attachment_text))

    msg = MIMEText(' Failed jobs list. Please see attachment')
    msg['Subject'] = 'Not run Jobs for ' + team_name
    msg['From'] = '[e-mail]'
    msg['To'] = '[e-mail]'

    f = io.StringIO(attachment_text)
    attachment = MIMEText(f.read())
    attachment.add_header('Content-Disposition', 'attachment', filename='test_attach')           
    msg.attach(attachment)

    s = smtplib.SMTP('smlsmtp')
    s.sendmail(msg['From'], msg['To'], msg.as_string())
    s.quit()
    print('
' + team_name + ' Email Sent')

错误:

Traceback (most recent call last):
  File "queue_cleaner_main.py", line 85, in <module>
    sys.exit(main())
  File "queue_cleaner_main.py", line 82, in main

Python 文档中的电子邮件示例

更紧密.我很确定这是因为我只使用 1 个 MIME 类型对象来构建我的电子邮件，但尝试添加多个 MIME 对象.基本上为了让它工作，我使用了下面的代码.快乐的日子！

more closely. Im pretty sure its because I was using only 1 MIME type object to build my email but trying to add multiple MIME objects. Basically to get it to work I used the below code. Happy days!

def email_sup_teams(team_name, contact_list, file_attachemnt):
    message_list = []
    for jobs in file_attachemnt:
        for k, v in jobs.items():
            message_list.append(v + ',')
    attachment_text = "
".join(message_list)
    print(type(attachment_text))
    # Create the container (outer) email message.
    msg = MIMEMultipart()
    #msg = MIMEText(' Failed jobs list. Please see attachment')
    msg['Subject'] = 'Not run Jobs for ' + team_name
    msg['From'] = '[e-mail]'
    msg['To'] = '[e-mail]'
    msg.preamble = 'Failed jobs list. Please see attachment'
    f = io.StringIO(attachment_text)
    attachment = MIMEText(f.getvalue())
    attachment.add_header('Content-Disposition', 'attachment', filename='jobs_not_run.xls')           
    msg.attach(attachment)

    s = smtplib.SMTP('smlsmtp')
    s.sendmail(msg['From'], msg['To'], msg.as_string())
    s.quit()
    print('
' + team_name + ' Email Sent')
