同时使用 IMAP 从 gmail 获取邮件

Question

我想从 Gmail 获取多封邮件消息，我正在使用 Imap。 在我尝试使用 ThreadPull 执行器（即使是 2 个执行器）加快速度之前，它的效果很好。

如果有人可以考虑导致该问题的原因是什么，那将非常有帮助。

连接器.py

 def create_data_models(self, msgs_ids, max_workers=2):
    data_models = []
    #msgs_id_list = [message['id'] for message in messages]
    with concurrent.futures.ThreadPoolExecutor(max_workers=max_workers) as executor:
        futures = {executor.submit(self.imapService.fetch_message, msg_id) : msg_id for msg_id in msgs_ids}
        for future in concurrent.futures.as_completed(futures):
            try:
                data = future.result()
                data_model = self._create_msg_obj1(data)
                data_models.append(data_model)
            except Exception as exc:
                print('generated an exception: %s' % (exc))
    
    return data_models

imap_service.py

    def fetch_message(self, msg_id):
        _, data = self.mail.uid('fetch', msg_id, '(RFC822)')
        _, mail_data = data[0]
        logger.error('Succesfully fetch message from {} with {} id'.format(self.email_address, msg_id))
        print('Succesfully fetch message from {} with {} id'.format(self.email_address, msg_id))
        return mail_data

错误：

用这个

 import imaplib import email host = input('Your Hostname: ') username = input('Your Username: ') password = input('Your Password: ') def get_inbox(): mail = imaplib.IMAP4_SSL(host) mail.login(username, password) mail.select("inbox") _, search_data = mail.search(None, 'SEEN') my_message = [] for num in search_data[0].split(): email_data = {} _, data = mail.fetch(num, '(RFC822)') # print(data[0]) _, b = data[0] email_message = email.message_from_bytes(b) for header in ['subject', 'to', 'from', 'date']: print("{}: {}".format(header, email_message[header])) email_data[header] = email_message[header] for part in email_message.walk(): if part.get_content_type() == "text/plain": body = part.get_payload(decode=True) email_data['body'] = body.decode() elif part.get_content_type() == "text/html": html_body = part.get_payload(decode=True) email_data['html_body'] = html_body.decode() my_message.append(email_data) return my_message if __name__ == "__main__": my_inbox = get_inbox() print(my_inbox) # print(search_data)
