Download a specific email from Gmail using Python

问题

Can someone help me customize an existing code sample?

I can see from the following article how to connect to gmail and download content, but I can't figure out how to search for a specific email and only download the timestamp and body?

ARTICLE: How can I download all emails with attachments from Gmail?

I specifically want to grab the emails from "Alerts@foobank.com" for the last 5 days and download the send time and body of the emails. I'll then parse this to determine which emails I need to use.

I'm self-taught and am having a hard time customizing the script above to do this.

Any help is much appreciated. Thanks.

I suggest using IMAPClient as it papers over many of the more esoteric aspects of IMAP.

The following snippet will pull messages based on your criteria, parse the message strings to email.message.Message instances and print the Date and From headers.

from datetime import datetime, timedelta
import email
from imapclient import IMAPClient

HOST = 'imap.gmail.com'
USERNAME = 'username'
PASSWORD = 'password'
ssl = True

today = datetime.today()
cutoff = today - timedelta(days=5)

## Connect, login and select the INBOX
server = IMAPClient(HOST, use_uid=True, ssl=ssl)
server.login(USERNAME, PASSWORD)
select_info = server.select_folder('INBOX')

## Search for relevant messages
## see http://tools.ietf.org/html/rfc3501#section-6.4.5
messages = server.search(
    ['FROM "Alerts@foobank.com"', 'SINCE %s' % cutoff.strftime('%d-%b-%Y')])
response = server.fetch(messages, ['RFC822'])

for msgid, data in response.iteritems():
    msg_string = data['RFC822']
    msg = email.message_from_string(msg_string)
    print 'ID %d: From: %s Date: %s' % (msgid, msg['From'], msg['date'])

import imaplib
from datetime import datetime, timedelta

obj = imaplib.IMAP4_SSL('imap.gmail.com',993)
obj.login('username','password')
obj.select()

today = datetime.today()
cutoff = today - timedelta(days=5)
dt = cutoff.strftime('%d-%b-%Y')
typ, data = obj.search(None, '(SINCE %s) (FROM "Alerts@foobank.com")'%(dt,))
print data
