如何使用 Python 3.7 将 excel 文件附加到 Gmail？

Question

我在 python 3.7 中创建了一个功能，用于为所有客户创建附有电子表格的电子邮件草稿。该代码正确地创建了电子邮件草稿并附加了文件 (.xlsx)，但这些文件无法再在 gmail 上打开。不确定这是否特定于我使用的编码。（文件在我的台式电脑上可以成功打开）

代码如下：

def CreateMessageWithAttachment(sender, to, cc, subject, message_text, file_dir, filename):
    """Create email messages with attachment, for sending to partners"""
    message = MIMEMultipart('alternative')
    message['to'] = to
    message['from'] = sender
    message['cc'] = cc
    message['subject'] = subject
    msg = MIMEText(message_text, 'html')
    message.attach(msg)
    path = os.path.join(file_dir, filename)
    content_type, encoding = mimetypes.guess_type(path)
    if content_type is None or encoding is not None:
        content_type = 'application/octet-stream'

    main_type, sub_type = content_type.split('/', 1)
    #    main_type, sub_type = 'gzip', None
    fp = open(path, 'rb')
    msg = MIMEBase(main_type, sub_type)
    msg.set_payload(fp.read())
    fp.close()
    msg.add_header('Content-Disposition', 'attachment', filename=filename)
    message.attach(msg)
    raw = base64.urlsafe_b64encode(message.as_bytes())
    raw = raw.decode()
    return {'raw': raw}
    #return {'raw': base64.urlsafe_b64encode(message.as_bytes()).decode()}

我假设是文件编码破坏了附加的电子表格。任何帮助将不胜感激。

尝试更改这两行：

msg = MIMEBase(main_type, sub_type)
msg.set_payload(fp.read())

仅此而已：

msg = MIMEApplication(fp.read(), sub_type)
