現(xiàn)在我有個問題想問一下，我打開一個LOG文件并輸出，最后怎么關閉這個LOG文件呢？shutdown?
代碼如下：
class CLogInfo:
#output the information to log,it will be instanced in testcase modele.
def __init__(self,logfile="testcase.log"):
try:
import logging
self.logger = None
self.logger = logging.getLogger()
self.hdlr = logging.FileHandler(logfile)
formatter = logging.Formatter("[%(asctime)s]: %(message)s","%Y-%m-%d %H:%M:%S")
self.hdlr.setFormatter(formatter)
self.logger.addHandler(self.hdlr)
self.logger.setLevel(logging.DEBUG)
except:
print "log init error!"
#exit(1)

def output(self,logInfo,errFlag=0):
try:
if (errFlag):
self.logger.error("error:"+logInfo)
#exit(errFlag)
else:
self.logger.info(logInfo)
except:
print "log output error!"
#exit(1)

def close(self):
try:
logging.shutdown([self.hdlr])
except error:
print "log closed error!"
#exit(1)

然后運行：
from logtest import CLogInfo,c1
log = CLogInfo("1.log")
log.output("aaa right")
這些都正確，但是
log.close()就提示錯誤，有知道如何關閉log文件的么？  回復  更多評論
  

I have find it:
self.logger.removeHandler(self.hdlr)  回復  更多評論
  

@APACHE
我試了一下是好用的，沒有錯誤，除了logging，error未定義。
你最好給出錯誤信息。
logging.shutdown()是關閉所有處理器。
用self.hdlr.close()也可以。  回復  更多評論
  

我有個問題想問一下，我想用log直接寫進數(shù)據(jù)庫

看見網(wǎng)上的例子14

不知道怎么錯誤了……因為我不知道，Log的信息什么的由哪里傳遞出來。  回復  更多評論
  

@feinix
錯誤信息呢？還要給出原例子的地址，看看你改了什么？

@金慶
多謝，我已經(jīng)找到了，是那個record,它帶有相關的屬性值。

我想知道，這里邊的config和log程序的編寫，有什么關系么？可以用設置來代替編寫？而且你寫這個日志程序怎么使用？在每個需要的模塊中直接調(diào)用？  回復  更多評論
