我正在设置python日志记录如下:

def setup_logging():
    loggers = (logging.getLogger("amcat"), logging.getLogger("scrapers"),logging.getLogger(__name__))
    filename = "somefile.txt"
    sys.stderr = open(filename, 'a')
    handlers = (logging.StreamHandler(sys.stdout),logging.FileHandler(filename))
    formatter = AmcatFormatter(date = True)

    for handler in handlers:
        handler.setLevel(logging.INFO)
        handler.setFormatter(formatter)

    for logger in loggers:
        logger.propagate = False
        logger.setLevel(logging.INFO)
        for handler in handlers:        
            logger.addHandler(handler)
    logging.getLogger().handlers = []

启用了2个主要模块记录器,它们都应该记录到控制台以及文件.错误被重定向到文件(理想情况下,错误也会显示在控制台中,但我还没有实现)

之后,我检查事情是否正确:

should_work = [
    "amcat.scraping.scraper",
    "amcat.scraping.htmltools",
    "amcat.scraping.controller",
    "__main__"]

loggerdict = logging.Logger.manager.loggerDict #all loggers
for name, logger in loggerdict.items():
    if name in should_work:
        print("\nlogger: "+name)
        #iterate through parents see if effective handlers are set correctly
        print(effectivehandlers(logger)) …
