的Python：IMAP连接到Gmail返回错误

Question

突然间，我的代码连接到Gmail和未读邮件检查不辍：

Connecting to Inbox.. 
Error 
Traceback (most recent call last): 
    File "./run", line 27, in <module> 
    mail.login("xxx@dddd.com", "xxxxx123") 
    File "/usr/lib/python2.6/imaplib.py", line 498, in login 
    typ, dat = self._simple_command('LOGIN', user, self._quote(password)) 
    File "/usr/lib/python2.6/imaplib.py", line 1060, in _simple_command 
    return self._command_complete(name, self._command(name, *args)) 
    File "/usr/lib/python2.6/imaplib.py", line 890, in _command_complete 
    raise self.abort('command: %s => %s' % (name, val)) 
imaplib.abort: command: LOGIN => socket error: EOF 

下面的代码：

#!/usr/bin/env python 

import imaplib, re 
import os 
import time 
import socket 

imap_host = 'imap.gmail.com' 
mail = imaplib.IMAP4_SSL(imap_host, 993) 
mail.login("xxxx@xxxx.com", "xxxx") 

while True: 
    try: 
     print 'Connecting to Inbox..' 
     mail.select("inbox") # connect to inbox. 
     result, data = mail.uid('search', None, 'UNSEEN') 
     uid_list = data[0].split() 
     print len(uid_list), 'Unseen emails.' 
     if len(uid_list) > 20: 
     os.system('heroku restart --app xxx-xx-203') 
     time.sleep(30) 
    except: 
     print 'Error' 
     time.sleep(120) 
     imap_host = 'imap.gmail.com' 
     mail = imaplib.IMAP4_SSL(imap_host, 993) 
     mail.login("xxx@xxx.com", "xxxx") 
     pass 

而且我也得到这个错误很多：

Traceback (most recent call last): 
    File "./run", line 10, in <module> 
    mail.login("xxx@xxx.com", "xxx") 
    File "/usr/lib/python2.6/imaplib.py", line 498, in login 
    typ, dat = self._simple_command('LOGIN', user, self._quote(password)) 
    File "/usr/lib/python2.6/imaplib.py", line 1060, in _simple_command 
    return self._command_complete(name, self._command(name, *args)) 
    File "/usr/lib/python2.6/imaplib.py", line 893, in _command_complete 
    self._check_bye() 
    File "/usr/lib/python2.6/imaplib.py", line 808, in _check_bye 
    raise self.abort(bye[-1]) 
imaplib.abort: [UNAVAILABLE] Temporary System Error 

Answer 1

奇怪。我跑了你确切的代码，并连接到Gmail就好了。我建议尝试从另一个系统连接。

如果你没有访问任何其他系统，我可以给你一个帐户，你可以尝试我的，如果你愿意。

这必然会最终发生。解决方案是捕获异常异常并重新初始化您的imap连接。
