;说明 : 1兆字节(mb)=1024千字节(kb) 1千字节(kb)=1024字节(b)

;说明 : 日志级别 : CRITICAL = 50 ERROR = 40 WARNING = 30 INFO = 20 DEBUG = 10 NOTSET = 0

;maxBytes : 每个日志文件最大为多少字节，到达最大数后自动分割 例如：10M = 10*1024*1024

;backupCount : 最多备份日志文件的数量

;outputConsole_level : 输出到控制台的日志信息等级，如为10，则只输出DEBUG及以上的信息

;outputFile_level : 输出到文件的日志信息等级

;log_file_path : 输出文件目录,支持绝对路径与相对路径 如 D:\Python\log.log 或 ./result/logging.log

;outputConsole = 1 开启控制台日志输出，0则关闭，outputFile = 1 开启文件日志输出， 0则关闭
