如何使用python将WorkMail电子邮件附件保存到tmp位置并推送到lambda中的s3

Question

我想使用 python 将我的电子邮件附件推送到 s3 存储桶，我的以下代码执行该任务，但是当新电子邮件以不同的文件名命中时，这不起作用。

我想将任何动态名称和扩展名上传到 s3 存储桶。

我是Python中的新蜜蜂。

提前致谢。

# Write the attachment to a temp location
    open('/tmp/filename.csv', 'wb').write(attachment.get_payload(decode=True))

您可以使用以下代码从 lambda 中提取附件：

def get_attachment(msg, content_type):
"""
Moves through a tree of email Messages to find an attachment.
:param msg: An email Message object containing an attachment in its Message tree
:param content_type: The type of attachment that is being searched for
:return: An email Message object containing base64 encoded contents (i.e. the attachment)
"""
attachment = None
msg_content_type = msg.get_content_type()

if ((msg_content_type == content_type or msg_content_type == 'text/plain')
        and is_base64(msg.get_payload())):
    attachment = msg

elif msg_content_type.startswith('multipart/'):
    for part in msg.get_payload():
        attachment = get_attachment(part, content_type)
        attachment_content_type = attachment.get_content_type()

        if (attachment and (attachment_content_type == content_type
                            or attachment_content_type == 'text/plain')
                and is_base64(attachment.get_payload())):
            break
        else:
            attachment = None

return attachment
