Python將過濾級別記錄到流中

我有一個簡單的模塊，只是啓動某些日誌處理程序和格式。

文件處理器
控制檯處理程序（拆分成標準錯誤和標準輸出）
我也有設置一些格式和過濾器。我在過濾器上遇到問題。
我想有2個處理器，一個過濾出 INFO和DEBUG消息（stderr流）和其他過濾掉警告及以上（離開INFO和DEBUG）

我不知道我建立了我的過濾器類correctly.I得到這個錯誤，這是不是很清楚，我：

TypeError: unbound method filter() must be called with STDErrFilter instance as first argument (got LogRecord instance instead)

這裏是我的代碼，並在此先感謝！：

import os 
import sys 
import logging 
import tempfile 

class STDOutFilter(logging.Filter): 
    def filter(self, record): 
     return record.levelno == logging.INFO | record.levelno == logging.DEBUG 

class STDErrFilter(logging.Filter): 
    def filter(self, record): 
     return not record.levelno == logging.INFO | record.levelno == logging.DEBUG 


def start_logbook(log_path=None, log_formatting=None, std_formatting=None, debug=False, clear_previous=True,): 

    log_level = logging.INFO if not debug else logging.DEBUG 
    stdout_level = logging.INFO if not debug else logging.DEBUG 

    logger = logging.getLogger() 
    logger.setLevel(log_level) 
    log_path = log_path 

    if log_path: 

     folder, filename = os.path.split(log_path) 

     if folder and not os.path.exists(folder): 
      raise IOError("path {0} does not exist!".format(folder)) 

    else: 
     # Setup Temp Log 
     log_path = tempfile.NamedTemporaryFile(prefix='tempLog'+'_log_', suffix='.log') 

    # Add File Handlers 
    file_handler = logging.FileHandler(log_path) 
    if clear_previous: 
     file_handler = logging.FileHandler(log_path, mode='w') 

    file_formatting = logging.Formatter('[%(asctime)s] %(levelname)-8s --- %(filename)s - %(funcName)s [%(lineno)d] - %(message)s', "%Y-%m-%d %H:%M:%S") 
    file_handler.setFormatter(file_formatting) 

    # Add Console Handler 
    error_console_handler = logging.StreamHandler(stream=sys.stderr) 
    error_console_handler.setLevel(stdout_level) 
    error_console_handler.addFilter(STDErrFilter) 

    info_console_handler = logging.StreamHandler(stream=sys.stdout) 
    info_console_handler.setLevel(stdout_level) 
    info_console_handler.addFilter(STDOutFilter) 


    console_formatting = logging.Formatter('%(levelname)-8s --- %(message)s') 
    error_console_handler.setFormatter(console_formatting) 
    info_console_handler.setFormatter(console_formatting) 

    logger.addHandler(error_console_handler) 
    logger.addHandler(info_console_handler) 
    logger.addHandler(file_handler) 

    return {'log_filepath': os.path.abspath(log_path), 'handlers':[error_console_handler, info_console_handler, file_handler]} 



if __name__ == '__main__': 
    info = start_logbook("test.log", debug=True) 

    log = logging.getLogger("Test Run") 

    log.debug("Debug Message goes Here") 
    log.info("INFO Message goes Here") 
    log.warning("WARNING Message goes Here") 
    log.error("ERROR Message goes Here") 
    log.critical("Critical Message goes Here") 
    log.exception(ValueError("Blarg")) 


    logging.shutdown(info['handlers'])

我明白了，愚蠢的錯誤。當我添加過濾器而不是傳遞實例化的對象時，我需要在代碼中實例化類。

# Add Console Handler 
error_console_handler = logging.StreamHandler(stream=sys.stderr) 
error_console_handler.setLevel(stdout_level) 
error_console_handler.addFilter(STDErrFilter()) # Problem was here I needed() 

info_console_handler = logging.StreamHandler(stream=sys.stdout) 
info_console_handler.setLevel(stdout_level) 
info_console_handler.addFilter(STDOutFilter()) # Problem was here! Needed()
