Python logging自定义字段输出及打印颜色
logging模块是Python的一个标准库模块，开发过程中，可以通过该模块，灵活的完成日志的记录。
logging模块提供了两种记录日志的方式：
1）使用logging提供的模块级别的函数（logging.basicConfig，logging.debug，logging.info...）
2）使用logging模块的组件（loggers，handlers，filters，formatters）
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):
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_.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设置
