Python电子邮件库-解析邮件/ rfc822附件

标签: python email eml rfc822

我正在使用python 2.7并试图解析作为附件收件箱转发的电子邮件。我似乎无法解析附件消息的标题/电子邮件。我将其视为“ message / rfc822”,但是当我尝试对其进行解析时,它显示为空。

我通过生成器提取消息,它可以正常工作,如下所示:

res, data = self.imap_client.fetch(msg_id, '(RFC822)')
msg = email.message_from_string(data[0][1])
yield msg

然后将这个味精推入另一个函数中(通过walk()),我拉出附件

attachments = []
for part in msg.walk():
    content_disposition = part.get('Content-Disposition', None)
    if content_disposition:
        attachments.append(Attachment(part, email_date))
return attachments

附件类如下:

class Attachment(object):
    def __init__(self, attachment, email_date=None):
        self.content_type = attachment.get_content_type()
        self.attachment = attachment
        fname = None
        if self.content_type.startswith('message/'):
            self.data = attachment.as_string()
            fname = 'mail.eml'
        else:
            self.data = attachment.get_payload(decode=True)
        try:
            self.size = len(self.data)
        except TypeError:
            self.size = 0
        if self.attachment.get_filename():
            fname = self.attachment.get_filename().strip().replace(' ', '-')
        self.name = re.sub(r'(?u)[^-\w.]', '', fname)
        self.date = email_date

我尝试使用get_payload拉附件,并仅使用as_string()传递附件(如上所述),但无济于事。当我尝试解析电子邮件附件时,它没有任何数据:

if attachment.content_type == "message/rfc822":
    msg = email.message_from_string(attachment.data)
    print msg.get('Subject', None)
