Python电子邮件.parser发展中

Question

最好的玩法是什么电子邮件.parserPython包？我有一个外部托管的网络服务器，我也可以发送电子邮件，但这个开发过程是非常乏味的，我觉得应该有一些我可以做的本地。在

有人有什么建议吗？在

我希望能够从电子邮件中提取图像附件，唯一的方法似乎是编写一些代码，将其放到我的web服务器上，给自己发送一些电子邮件，然后检查发生了什么。我希望在当地模仿这个过程。在

你到底想做什么？您当前使用服务器的目的是什么？在

您可以使用email.parser.FeedParser.feed(...)从字符串传入电子邮件。因此，您只需在本地存储一些电子邮件并以这种方式发送它们：

import email.parser
parser = email.parser.FeedParser()

email = '''\
From: Steve <steve@steve.steve>
To: Someone <someone@foo.com>
Subject: Hey what's up

This is a dummy email, no server involved.
'''

parser.feed(email)
msg = parser.close()

print "To:", msg['to']
print "From:", msg['from']
print "Subject:", msg['subject']
print "Body:", repr(msg.get_payload())

输出：

^{pr2}$

编辑：为了回应您关于提取附件（例如图像）的评论，电子邮件附件跟随MIME standard。您可以复制原始电子邮件（取决于您使用的客户机和服务器），也可以按照标准手工构建自己的电子邮件。在

下面是一个PNG文件的示例：

import email.parser
parser = email.parser.FeedParser()

email = '''\
From: Steve <steve@steve.steve>
To: Someone <someone@foo.com>
Subject: Hey what's up
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=_boundary

This is a message with multiple parts in MIME format.

 _boundary
Content-Type: text/plain

This is the body of the message. No mail server involved.

 _boundary
Content-Type: application/octet-stream
Content-Disposition: attachment; filename=test.png;
Content-Transfer-Encoding: base64

当我将该文件写入磁盘时，它是一个有效的PNG文件：

$ python -i x.py
>>> open('x.png', 'wb').write(payload.get_payload().decode('base64'))

$ file x.png
