[英]Python: Code crashes randomly when checking e-mail
这段代码:
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:
0
1
0
0
0
0
0
4
Traceback (most recent call last):

socket.error: [Errno 60] Operation timed out
我不明白为什么它会随机崩溃。
最后一条错误线是描述性的:IMAP操作完成之前,连接已超时。 可能只是Gmail运行缓慢。 如果是这样,您可以尝试延长超时时间,如下所示:
import socket
socket.setdefaulttimeout(15) # In seconds
其中15
是您实验确定的值,对您来说效果很好。
