Question

我有点拼凑了一些脚本，我在网上发现了一些快速的家庭自动化＆＃34;使用Raspberry Pi进行概念验证的演示。我后来意识到它也可以用作一个没有响应的终端＆＃34;同样。很抱歉没有给代码的原始所有者，因为我不记得我在哪里找到它，并且开始时没有信用。

反正。我已经对它做了自己的改动，而且效果很好。我把它设置为pi上的一个新贵守护进程，它运行查找并运行它应该2-5天。然后它将挂起，在脚本中的某个地方，并且从不实际执行except：进行错误处理。实际上，我编写并作为守护进程运行的3个脚本中有2个会执行此操作。

这是我的代码。

import imaplib
import email
import GPIO
import subprocess
import prowlpy
import time
import sys
import logging

logger = logging.getLogger('error.log')
# Configure logger to write to a file...

def my_handler(type, value, tb):
    logger.exception("Uncaught exception: {0}".format(str(value)))

# Install exception handler
sys.excepthook = my_handler

pnotify = prowlpy.Prowl(###)    
if __name__ == '__main__':
    while True:
        try:
            mail = imaplib.IMAP4_SSL('imap.gmail.com')
            mail.login('###', '###')

            mail.select('inbox')    
            mail.list()

            typ, data = mail.search(None, 'ALL')
            for num in data[0].split():
                typ, data = mail.fetch(num, '(RFC822)')
            typ, data = mail.search(None, 'ALL')
            ids = data[0]
            id_list = ids.split()

            if id_list:
                latest_email_id = int( id_list[-1] )
                for i in range( latest_email_id, latest_email_id-1, -1):
                    typ, data = mail.fetch( i, '(RFC822)')
                for response_part in data:
                    if isinstance(response_part, tuple):
                        msg = email.message_from_string(response_part[1])
                varSubject = msg['subject']
                varFrom = msg['from']
                varFrom = varFrom.replace('<','')
                varFrom = varFrom.replace('>','')
                if varSubject == 'Lights - ON' :
                    varSubject = 1
                    GPIO.writePin(3, 0)
                    pnotify.add('RPi', 'Welcome Home', 'Notification', -2)
                elif varSubject == 'Lights - OFF' :
                    varSubject = 1
                    GPIO.writePin(3, 1)
                    pnotify.add('RPi', 'Have a nice day!', 'Notification', -2)
                elif 'CMD' in varSubject and '###' in varFrom: #REQUIRES VALIDATION
                    subprocess.call(varSubject.split("- ")[1], shell=True)
                    pnotify.add('RPi', 'CMD EXEC - '+varSubject.split("- ")[1], 'Notification', -2)
                    varSubject = 1
                else :
                    varSubject = 0 
            else: #No Emails
                varSubject = 0



            #Remove used emails from mailbox
            typ, data = mail.search(None, 'ALL')
            for num in data[0].split():
                mail.store(num, '+FLAGS', '\\Deleted')
            mail.expunge()
            mail.close()
            mail.logout()
        except:
            print "Could not establish connection or some other error... waiting 20s" 
            time.sleep(20)
            sys.exit()

脚本不会处理错误
