【中文标题】如何仅从特定 gmail 标签下载未读附件?【英文标题】:How do I download only unread attachments from a specific gmail label? 【发布时间】:2012-04-28 06:39:13 【问题描述】:我有一个改编自 Downloading MMS emails sent to Gmail using Python 的 Python 脚本
import email, getpass, imaplib, os
detach_dir = '.' # directory where to save attachments (default: current)
user = raw_input("Enter your GMail username:")
pwd = getpass.getpass("Enter your password: ")
# connecting to the gmail imap server
m = imaplib.IMAP4_SSL("imap.gmail.com")
m.login(user,pwd)
m.select("[Gmail]/All Mail") # here you a can choose a mail box like INBOX instead
# use m.list() to get all the mailboxes
resp, items = m.search(None, 'FROM', '"Impact Stats Script"') # you could filter using the IMAP rules here (check http://www.example-code.com/csharp/imap-search-critera.asp)
items = items[0].split() # getting the mails id
for emailid in items:
resp, data = m.fetch(emailid, "(RFC822)") # fetching the mail, "`(RFC822)`" means "get the whole stuff", but you can ask for headers only, etc
email_body = data[0][1] # getting the mail content
mail = email.message_from_string(email_body) # parsing the mail content to get a mail object
#Check if any attachments at all
if mail.get_content_maintype() != 'multipart':
continue
print "["+mail["From"]+"] :" + mail["Subject"]
# we use walk to create a generator so we can iterate on the parts and forget about the recursive headach
for part in mail.walk():
# multipart are just containers, so we skip them
if part.get_content_maintype() == 'multipart':
continue
# is this part an attachment ?
if part.get('Content-Disposition') is None:
continue
filename = part.get_filename()
counter = 1
# if there is no filename, we create one with a counter to avoid duplicates
if not filename:
filename = 'part-%03d%s' % (counter, 'bin')
counter += 1
att_path = os.path.join(detach_dir, filename)
#Check if its already there
if not os.path.isfile(att_path) :
# finally write the stuff
fp = open(att_path, 'wb')
fp.write(part.get_payload(decode=True))
fp.close()
我正在按主题过滤邮件并获取附件,但现在我只需要从 新 电子邮件中获取附件。我可以修改m.search()
以仅返回未读邮件吗?
【问题讨论】:
附件是新的是什么意思?发送电子邮件后,附件已修复... 我的意思是带有附件的新电子邮件。我将编辑问题。 【参考方案1】:尝试修改这一行:
resp, items = m.search(None, 'FROM', '"Impact Stats Script"')
到:
resp, items = m.search(None, 'UNSEEN', 'FROM', '"Impact Stats Script"')
Python imaplib
documentation shows just adding more search criteria 和 the IMAP specification 定义了 UNSEEN
搜索条件:
UNSEEN
Messages that do not have the \Seen flag set.
【讨论】:
NEW 不起作用,但 UNSEEN 本身就可以。谢谢。如果您在答案中将 NEW 更改为 UNSEEN,我会将其标记为已接受。我不清楚是否可以像这样将条件添加到搜索中。 您好,我是 gmail 脚本的新手。这个脚本是否仍然有效,如果可以,我在哪里执行它? @Adam,据我所知,gmail 没有脚本。这是一个 Python 脚本,您可以使用 Python 解释器执行它。以上是关于如何仅从特定 gmail 标签下载未读附件?的主要内容,如果未能解决你的问题,请参考以下文章
