如何判断imaplib2空闲响应是否是由于超时导致的 [英] How to tell whether imaplib2 idle response resulted from timeout

问题描述

我正在使用 imaplib2 (

I'm using imaplib2 (docs) to interact with an IMAP server.

我正在使用带有超时和回调的idle命令.

I'm using the idle command, with a timeout and a callback.

问题是，我看不到任何方法来判断回调是由超时触发的，还是服务器上需要我签出的更改.

The problem is, I don't see any way of telling if the callback was triggered by the timeout being reached, or if there was a change on the server that I need to check out.

我每次都会得到('OK', ['IDLE terminated (Success)']).

这是这两种情况的调试输出:

Here's the debug output for both cases:

超时:

15:43.94 MainThread server IDLE started, timeout in 5.00 secs
15:48.94 imap.gmail.com handler server IDLE timedout
15:48.94 imap.gmail.com handler server IDLE finished
15:48.94 imap.gmail.com writer > DONE\r\n
15:49.17 imap.gmail.com reader < DDDM6 OK IDLE terminated (Success)\r\n
15:49.17 imap.gmail.com handler _request_pop(DDDM6, ('OK', ['IDLE terminated (Success)']))

发生了什么事

18:41.34 MainThread server IDLE started, timeout in 50.00 secs
19:01.35 imap.gmail.com reader < * 1 EXISTS\r\n
19:01.37 imap.gmail.com handler server IDLE finished
19:01.37 imap.gmail.com writer > DONE\r\n
19:01.59 imap.gmail.com reader < BFCN6 OK IDLE terminated (Success)\r\n
19:01.59 imap.gmail.com handler _request_pop(BFCN6, ('OK', ['IDLE terminated (Success)']))

我想念什么?

imaplib2中是否不存在该功能?

Does the functionality just not exist in imaplib2?

推荐答案

Piers Lauder(imaplib2的作者)刚刚在imaplib2-devel邮件列表中回答了这个问题.他说:

Piers Lauder (author of imaplib2) just answered this question on the imaplib2-devel mailing list. He said:

我认为测试空闲状态是否超时的方法是执行:

I think the way to test if an IDLE has timed out is to execute:

instance.response('IDLE')

它将返回:

('IDLE', ['TIMEOUT'])

如果空闲返回超时的原因，而不是 其他(例如('IDLE', [None])).

if the reason that the idle returned as a timeout, rather than something else (such as ('IDLE', [None])).

我同意应对此进行记录，因此我将修复imaplib2.html 文件

I agree that this should be documented, so I'll fix the imaplib2.html document
