Question

我在python 3.7中创建了一个函数，用于为所有客户端创建带有附加电子表格的电子邮件草稿。该代码可正确创建该电子邮件草稿并附加文件（.xlsx），但无法再在gmail上打开这些文件。不知道这是否特定于我正在使用的编码。（可以在我的台式计算机上成功打开文件）

下面是代码：

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()}

我认为，文件的编码是损坏所附电子表格的原因。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())

要这样：

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

如何使用Python 3.7将Excel文件附加到Gmail？
