Python logging自定义字段输出及设置日志打印颜色

简单示例

import json
import logging


class JsonFilter(logging.Filter):
    #此处定义字段的默认值,如果打印信息时不设置对应字段，则为默认值
    #服务服务名或者服务主机
    server = ""
    #访问ip
    ip = ""
    #访问资源路径
    sourceurl = ""
    #访问方式
    method = ""
    # 访问设备
    devices = ""
    # 访问协议
    Protocols = ""
    #访问结果的HTTP状态码
    result_Httpstatus = ""
    #访问结果的状态码
    result_status = ""
    #访问结果的msg信息
    result_msg = ""
    #访问结果的数据大小
    result_msgsize = ""
    def filter(self, record):

        return True



if __name__ == '__main__':

    formate = json.dumps({

    })
    logging.basicConfig(level=logging.DEBUG,format=formate)

    filter_.result_msg = '增加成功'
    filter_.result_msgsize = '4296'
    logger.info("") #如果你需要在打印字段中设置
