yaml

今天用yaml文件写了一下logging的配置，文件如下：

version: 1disable_existing_loggers: Falseformatters:    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: utf8loggers:    my_module:        level: ERROR        handlers: [console]        propagate: noroot:    level: INFO    handlers: [console, info_file_handler]

只是做个demo，所以写的比较粗略，然后中间就是包含了formatter，handlers，并没有使用filters，最终的效果是ERROR级别的信息将会在命令台进行打印并写入日志文件当中。

try_log.py

# -*- coding: utf-8 -*-import osimport yamlimport loggingfrom logging import config as logger_configconfig_file = os.path.join(os.path.dirname(__file__), "config.yaml")if os.path.exists("mylog"):    passelse:    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.")

运行这个命令就可以看到相应的结果了。
