yaml文件配置logger

yaml

今天用yaml文件寫了一下logging的配置，文件以下：

version: 1
disable_existing_loggers: False
formatters:
    simple:
        format: "%(asctime)s - %(filename)s - %(levelname)s - %(message)s"
handlers:
    console:
        class: logging.StreamHandler
        level: ERROR
        formatter: simple
        stream: ext://sys.stdout

    info_file_handler:
        class: logging.handlers.RotatingFileHandler
        level: INFO
        formatter: simple
        filename: ./mylog/info.log
        maxBytes: 10485760
        backupCount: 20
        encoding: utf8

    error_file_handler:
        class: logging.handlers.RotatingFileHandler
        level: ERROR
        formatter: simple
        filename: errors.log
        maxBytes: 10485760
        backupCount: 20
        encoding: utf8

loggers:
    my_module:
        level: ERROR
        handlers: [console]
        propagate: no

root:
    level: INFO
    handlers: [console, info_file_handler]

只是作個demo，因此寫的比較粗略，而後中間就是包含了formatter，handlers，並無使用filters，最終的效果是ERROR級別的信息將會在命令臺進行打印並寫入日誌文件當中。

try_log.py

# -*- coding: utf-8 -*-


import os
import yaml
import logging
from logging import config as logger_config


config_file = os.path.join(os.path.dirname(__file__), "config.yaml")

if os.path.exists("mylog"):
    pass
else:
    os.mkdir("mylog")

with open(config_file, "rt") as stream:
    config = yaml.unsafe_load(stream.read())

logger_config.dictConfig(config)
logger = logging.getLogger()


if __name__ == "__main__":
    logger.error("This is a test error message for my first logger.")

運行這個命令就能夠看到相應的結果了。
