使用 :
log = loggingUtils.loggingUtils('/tmp/ttx.log')
log.
debug('debug')
try :
1/0
except :
log.error('异常')
log.error_sys()
代码:
#!/usr/bin/python
#encoding: utf-8
import sys,traceback
class loggingUtils :
def __init__(self,logfile) :
import logging
self.logger = logging.getLogger(logfile)
self.hdlr = logging.FileHandler(logfile)
formatter = logging.Formatter('%(asctime)s %(levelname)s - %(message)s')
self.hdlr.setFormatter(formatter)
self.logger.addHandler(self.hdlr)
self.logger.setLevel(logging.DEBUG)
def debug(self,msg):
self.logger.debug( msg )
self.hdlr.flush()
#logger.removeHandler( hdlr )网络上的实现基本为说明这条语句的使用和作用
def error(self,eline):
self.logger.error(eline)
self.hdlr.flush()
def error_sys(self,limit=None):
exceptionType, exceptionValue, exceptionTraceback = sys.exc_info()
if limit is None:
if hasattr(sys, 'tracebacklimit'):
limit = sys.tracebacklimit
n = 0
eline = '\n'
while exceptionTraceback is not None and (limit is None or n < limit):
f = exceptionTraceback.tb_frame
lineno = exceptionTraceback.tb_lineno
co = f.f_code
filename = co.co_filename
name = co.co_name
eline += ' File "%s", line %d, in %s \n ' % (filename,lineno,name)
exceptionTraceback = exceptionTraceback.tb_next
n = n+1
eline+= "\n".join(traceback.format_exception_only(exceptionType, exceptionValue))
self.logger.error(eline)
self.hdlr.flush()
