Python3 多线程 更新token报错

[SJK132]

更新token以后 会报错

#Wechat Auto Reply logic
@itchatmp.msg_register(itchatmp.content.TEXT)
def text_reply(msg):

    if(msg['Content'].isdigit() and len(msg['Content']) == 5):
        return addjob(msg['FromUserName'],msg['Content'])

        WrongCRN = [u'好像没有这个课号呢！课号一般是5位数。',u'难受！没这个课号！再试试其他的吧！',u'逗我呢？',u'你**在给我free style吗？']
        return random.choice(WrongCRN)


@itchatmp.access_token
def producer(accessToken=None):
    while(1):
        if hasUpdated():
            itchatmp.send(str(datetime.datetime.now()),'oO3tH0e3rt_j85k3ASkztTBM8Mec')
            print('1')
        else:
            sleep(1)
            continue


#MultiThread

###### main auto reply ######
replyThread = threading.Thread(target=itchatmp.run)
# prevent Main Thread to continue
replyThread.setDaemon(True)
# start as Daemon
replyThread.start()

###### producer #####
producer = threading.Thread(target=producer)
producer.setDaemon(True)
producer.start()

replyThread.join()
producer.join()

每次都是Update Token以后 第二个thread 会报错
