Question

此代码：

import imaplib, re
import os
import time

conn = imaplib.IMAP4_SSL("imap.gmail.com", 993)
conn.login("ddd@ddd.com", "ddd")

while(True):
    unreadCount = re.search("UNSEEN (\d+)", conn.status("INBOX", "(UNSEEN)")[1][0]).group(1)
    print unreadCount

    if int(unreadCount) > 20:
      os.system('heroku restart --app warm-beach-203')
        #os.system('ls')
        #print "Restarting server...."

    time.sleep(60)

输出：

socket.error: [Errno 60] Operation timed out

我不明白为什么它会随机崩溃。

最终错误行是描述性的：连接在IMAP操作完成之前超时。可能只是Gmail运行缓慢。如果是这种情况，您可以尝试延长超时：

import socket
socket.setdefaulttimeout(15)  # In seconds

其中15是您通过实验确定的值适合您。
