Python logging自定義字段輸出及打印顏色

更新時(shí)間：2020年11月30日 11:22:11 作者：-零

這篇文章主要介紹了Python logging自定義字段輸出及打印顏色,文中通過(guò)示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值,需要的朋友可以參考下

logging模塊是Python的一個(gè)標(biāo)準(zhǔn)庫(kù)模塊，開(kāi)發(fā)過(guò)程中，可以通過(guò)該模塊，靈活的完成日志的記錄。

logging模塊提供了兩種記錄日志的方式：

1）使用logging提供的模塊級(jí)別的函數(shù)（logging.basicConfig，logging.debug，logging.info...）

2）使用logging模塊的組件（loggers，handlers，filters，formatters）

簡(jiǎn)單示例

import json
import logging


class JsonFilter(logging.Filter):
  #此處定義字段的默認(rèn)值,如果打印信息時(shí)不設(shè)置對(duì)應(yīng)字段，則為默認(rèn)值
  #服務(wù)服務(wù)名或者服務(wù)主機(jī)
  server = ""
  #訪問(wèn)ip
  ip = ""
  #訪問(wèn)資源路徑
  sourceurl = ""
  #訪問(wèn)方式
  method = ""
  # 訪問(wèn)設(shè)備
  devices = ""
  # 訪問(wèn)協(xié)議
  Protocols = ""
  #訪問(wèn)結(jié)果的HTTP狀態(tài)碼
  result_Httpstatus = ""
  #訪問(wèn)結(jié)果的狀態(tài)碼
  result_status = ""
  #訪問(wèn)結(jié)果的msg信息
  result_msg = ""
  #訪問(wèn)結(jié)果的數(shù)據(jù)大小
  result_msgsize = ""
  def filter(self, record):
    record.server = self.server
    record.ip = self.ip

    record.method = self.method
    record.devices = self.devices
    record.Protocols = self.Protocols
    record.result_Httpstatus = self.result_Httpstatus
    record.result_status = self.result_status
    record.result_msg = self.result_msg
    record.result_msgsize = self.result_msgsize
    return True



if __name__ == '__main__':

  formate = json.dumps({
  "time": "%(asctime)s",
  "levelname": "%(levelname)s",
  "server": "%(server)s",
  "ip": "%(ip)s",
  "sourceurl": "%(sourceurl)s",
  "method": "%(method)s",
  "devices": "%(devices)s",
  "Protocols": "%(Protocols)s",
  "result_Httpstatus": "%(result_Httpstatus)s",
  "result_status": "%(result_status)s",
  "result_msg": "%(result_msg)s",
  "result_msgsize": "%(result_msgsize)s",
  })
  logging.basicConfig(level=logging.DEBUG,format=formate)
  logger = logging.getLogger()
  filter_ = JsonFilter()
  logger.addFilter(filter_)

  filter_.server = '127.0.0.1:8100'
  filter_.ip = '127.0.0.1'
  filter_.sourceurl = 'http://127.0.0.1:8100/test'
  filter_.method = 'Get'
  filter_.devices = 'Chrome'
  filter_.Protocols = 'HTTP'
  filter_.result_Httpstatus = '200'
  filter_.result_status = '1001'
  filter_.result_msg = '增加成功'
  filter_.result_msgsize = '4296'
  logger.info("") #如果你需要在打印字段中設(shè)置
