Python日志模块

做自动化的时候，我们需要给框架配上日志，出错的时候方便我们查看。

例子：

　　

import logging
from Agin_Project.unittest_again.common.file_path import FilePath
class My_log:
    def conf_log(self,level,msg):

        log = logging.getLogger("test_log") #创建一个日志收集器
        log.setLevel(level) #设置日志的级别

        # 日志的输出格式
        formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(funcName)s - %(module)s - %(lineno)d : %(message)s')

        #输出日志到控制台
        pull = logging.StreamHandler()
        pull.setLevel(level)
        pull.setFormatter(formatter)

        #存放日志文件的目录
        file_path = FilePath().file_log_path("log.txt")
        #输出日志到文件
        file_log =logging.FileHandler(file_path,encoding="utf-8")
        file_log.setLevel(level)
        file_log.setFormatter(formatter)

        #添加到log里面
        log.addHandler(pull)
        log.addHandler(file_log)

        #判断日志的级别
        if level.upper() == "DEBUG":
            log.debug(msg)

        elif level.upper() == "INFO":
            log.info(msg)

        elif level.upper() == "WARNING":
            log.warning(msg)

        elif level.upper() == "ERROR":
            log.error(msg)

        elif level.upper() == "CRITICAL":
            log.critical(msg)

        #最要要移除日志，不然会有重复的
        log.removeHandler(pull)
        log.removeHandler(file_log)

    def msg_debug(self,msg):
        self.conf_log("DEBUG",msg)

    def msg_info(self,msg):
        self.conf_log("INFO",msg)

    def msg_warning(self,msg):
        self.conf_log("WARNING",msg)

    def msg_error(self,msg):
        self.conf_log("ERROR",msg)

    def msg_critical(self,msg):
        self.conf_log("CRITICAL",msg)
