找不到记录器“apscheduler.scheduler"的处理程序. [英] No handlers could be found for logger "apscheduler.scheduler"

问题描述

from apscheduler.scheduler import Scheduler
import os
class ListHref():
    def __init__(self):
       print 'In ListHref Class!'
       self.name_hrefs = {}
       self.name_img = {}
       self.path = os.path.dirname(__file__)
       print 'Out ListHref Class'
    def other_function():...

def job(): #function named job
    print 'In job!'
    book_href = ListHref()
    print 'book_href created!'

if __name__ == "__main__":
    sched = Scheduler()
    #job() #it's ok if job() called only
    sched.daemonic = False #non daemon thread 
    sched.add_interval_job(job,minutes=0.1)
    sched.start()

问题:如果只调用 job() 而不是 sched，没关系所以我很困惑为什么 init(self) 不能完全调用?并且找不到记录器apscheduler.scheduler"的处理程序有什么问题?以上python代码结果:

Problem: If call job() only instead of sched,it's ok So I am confused that why the init(self) cannot called completely? and what's wrong with 'No handerls could be found for logger "apscheduler.scheduler"'? Above python code result:

在作业()

在 ListHref 类中！

In ListHref Class!

找不到记录器apscheduler.scheduler"的处理程序

No handerls could be found for logger "apscheduler.scheduler"

在作业()

在 ListHref 类中！

In ListHref Class!

在作业()

在 ListHref 类中！

In ListHref Class!

...(以此类推)

推荐答案

apscheduler 正在使用 python logging 模块 需要初始化.日志记录有点复杂(请参阅链接)，但最低限度是:

apscheduler is using the python logging module which needs to be initialized. Logging is a bit complicated (see the link) but the minimum is to:

import logging
logging.basicConfig()

basicConfig 支持一些常见的日志记录功能，但值得了解记录器的一些更复杂的用途.

basicConfig supports some common logging features but its worth figuring out some of the more sophisticated uses for the logger.
