我环顾四周并尝试了更多的东西。这些:
使用 imaplib 下载多个附件
以及如何仅从特定 gmail 标签下载未读附件?一旦我玩了一下它就有了答案。
有效的代码:
import imaplib
import email
import os
svdir = 'c:/downloads'
mail=imaplib.IMAP4('mailserver')
mail.login("username","password")
mail.select("DetReport")
typ, msgs = mail.search(None, '(SUBJECT "Detection")')
msgs = msgs[0].split()
for emailid in msgs:
resp, data = mail.fetch(emailid, "(RFC822)")
email_body = data[0][1]
m = email.message_from_string(email_body)
if m.get_content_maintype() != 'multipart':
continue
for part in m.walk():
if part.get_content_maintype() == 'multipart':
continue
if part.get('Content-Disposition') is None:
continue
filename=part.get_filename()
if filename is not None:
sv_path = os.path.join(svdir, filename)
if not os.path.isfile(sv_path):
print sv_path
fp = open(sv_path, 'wb')
fp.write(part.get_payload(decode=True))
fp.close()
POP3:
import poplib
import email
server = poplib.POP3(pop_server)
server.user(user)
server.pass_(pass)
# get amount of new mails and get the emails for them
messages = [server.retr(n+1) for n in range(len(server.list()[1]))]
# for every message get the second item (the message itself) and convert it to a string with \n; then create python email with the strings
emails = [email.message_from_string('\n'.join(message[1])) for message in messages]
for mail in emails:
# check for attachment;
for part in mail.walk():
if not mail.is_multipart():
continue
if mail.get('Content-Disposition'):
continue
file_name = part.get_filename()
# check if email park has filename --> attachment part
if file_name:
file = open(file_name,'w+')
file.write(part.get_payload(decode=True))
file.close()
