Python logging自定義欄位輸出及列印顏色
阿新 • • 發佈：2020-12-01
logging模組是Python的一個標準庫模組，開發過程中，可以通過該模組，靈活的完成日誌的記錄。
logging模組提供了兩種記錄日誌的方式：
1）使用logging提供的模組級別的函式（logging.basicConfig，logging.debug，logging.info...）
2）使用logging模組的元件（loggers，handlers，filters，formatters）
簡單示例
import json
import logging
class JsonFilter(logging.Filter):
#此處定義欄位的預設值,如果列印資訊時不設定對應欄位，則為預設值
#服務服務名或者服務主機
server = ""
#訪問ip
ip = ""
#訪問資源路徑
sourceurl = ""
#訪問方式
method = ""
# 訪問裝置
devices = ""
# 訪問協議
Protocols = ""
#訪問結果的HTTP狀態碼
result_Httpstatus = ""
#訪問結果的狀態碼
result_status = ""
#訪問結果的msg資訊
result_msg = ""
#訪問結果的資料大小
result_msgsize = ""
def filter(self,record):
record.server = self.server
record.ip = self.ip
record.sourceurl = self.sourceurl
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_.result_status = '1001'
