Python：继续检查新电子邮件并提醒更多新电子邮件 [英] Python: Keep checking new email and alert of further new emails

问题描述

我有这段代码可以检查最新的电子邮件，然后执行某些操作。是否可以编写一些东西来不断检查收件箱文件夹中是否有新邮件？虽然我希望它继续检查最新的电子邮件。如果我尝试存储它已经通过了一次，是否变得太复杂了？因此，它不会针对同一封电子邮件两次提醒同一封电子邮件。

I have this code that checks the latest email and then goes and does something. Is it possible to write something that keeps checking the inbox folder for new mail? Although I want it to keep checking for the latest new email. Is it getting too complicated if I try and store that it has made one pass? So it doesn't alert about the same email twice about the same email.

代码：

import imaplib
import email
import Tkinter as tk

word = ["href=", "href", "<a href="] #list of strings to search for in email body

#connection to the email server
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login('xxxx', 'xxxx')
mail.list()
# Out: list of "folders" aka labels in gmail.
mail.select("Inbox", readonly=True) # connect to inbox.

result, data = mail.uid('search', None, "ALL") # search and return uids instead

ids = data[0] # data is a list.
id_list = ids.split() # ids is a space separated string
latest_email_uid = data[0].split()[-1]

result, data = mail.uid('fetch', latest_email_uid, '(RFC822)') # fetch the email headers and body (RFC822) for the given ID


raw_email = data[0][1] # here's the body, which is raw headers and html and body of the whole email
# including headers and alternate payloads

.....goes and does other code regarding to email html....

尝试使用此方法：

逻辑与@tripleee注释相同。

Logic is the same as from @tripleee comment.

import time
word = ["href=", "href", "<a href="] #list of strings to search for in email body

#connection to the email server
mail = imaplib.IMAP4_SSL('imap.gmail.com')
mail.login('xxxx', 'xxxx')
mail.list()
# Out: list of "folders" aka labels in gmail.
latest_email_uid = ''

while True:
    mail.select("Inbox", readonly=True)
    result, data = mail.uid('search', None, "ALL") # search and return uids instead
    ids = data[0] # data is a list.
    id_list = ids.split() # ids is a space separated string

    if data[0].split()[-1] == latest_email_uid:
         time.sleep(120) # put your value here, be sure that this value is sufficient ( see @tripleee comment below)
    else:
         result, data = mail.uid('fetch', latest_email_uid, '(RFC822)') # fetch the email headers and body (RFC822) for the given ID
         raw_email = data[0][1]
         latest_email_uid == data[0].split()[-1]
         time.sleep(120) # put your value here, be sure that this value is sufficient ( see @tripleee comment below)
