python日志记录dictConfig自定义格式化程序不被称为

Question

我在我的模块中有以下ColoeredFormatter。

但格式化程序没有被调用。我希望控制台上有“hi”，但我得到“这是根记录器的信息”。

我已经删除了所有的.pyc文件，但没有帮助。

MyModule的/ __ init__.py

from MyModule.ColoredFormatter import ColoredFormatter 

__all__ = ('ColoredFormatter') 

MyModule的/ ColoredFormatter.py

import logging 

class ColoredFormatter(logging.Formatter): 
    def __init__(self, default): 
     self.default = default 

    def format(self, record): 
     print("hi") 
     record.msg = "hi" 
     return self.default.format(record) 

我的脚本

import logging, logging.config, yaml 

conf=""" 
logging: 
    version: 1 
    disable_existing_loggers: true 
    root: 
    level: !!python/name:logging.NOTSET 
    handlers: [console] 
    handlers: 
    console: 
     class: logging.StreamHandler 
     stream: ext://sys.stdout 
     formatter: myFormatter 
     level: !!python/name:logging.NOTSET 

    formatters: 
    myFormatter: 
     class: !!python/name:MyModule.ColoredFormatter 
""" 
dict = yaml.parse(conf) 
logging.config.dictConfig(dict["logging"]) 

logging.info("This is an info of the root logger") 

Answer 1

在格式化部分我不得不()

import logging, logging.config, yaml 

conf=""" 
logging: 
    version: 1 
    disable_existing_loggers: true 
    root: 
    level: !!python/name:logging.NOTSET 
    handlers: [console] 
    handlers: 
    console: 
     class: logging.StreamHandler 
     stream: ext://sys.stdout 
     formatter: myFormatter 
     level: !!python/name:logging.NOTSET 

    formatters: 
    myFormatter: 
     '()': MyModule.ColoredFormatter 
""" 
dict = yaml.parse(conf) 
logging.config.dictConfig(dict["logging"]) 

logging.info("This is an info of the root logger")
