python脚本实现统计日志文件中的ip访问次数代码分享

适用的日志格式：

106.45.185.214--[06/Aug/2014:07:38:59+0800]"GET/HTTP/1.0"20010"-""-"
171.104.119.22--[06/Aug/2014:08:55:01+0800]"GET/HTTP/1.0"20010"-""-"
27.31.238.242--[06/Aug/2014:09:43:19+0800]"GET/HTTP/1.0"20010"-""-"
218.65.202.131--[06/Aug/2014:10:33:59+0800]"GET/HTTP/1.0"20010"-""-"

以上为nginx的日志,本程序只适合用于IP在开头并用空格分开的这种格式。

实例代码：

importsys

classLog:

def__init__(self,filename,dic,count):
self.filename=filename
self.dic=dic
self.count=count

defparse(self):
i=1
f=file(self.filename)
whileTrue:
line=f.readline()
iflen(line)==0:
break
ip=line.split("")
ifip[0]indic:
self.dic[ip[0]]=self.dic[ip[0]]+1
else:
self.dic[ip[0]]=i
soredic=sorted(self.dic.items(),key=lambdad:d[1],reverse=True)
counts=0;
foriteminsoredic:
ifcounts==int(self.count):
break
print("IP:%sTotalTimes:%s"%(item[0],item[1]))
counts=counts+1
f.close()

if__name__=="__main__":

iflen(sys.argv)<3:
print("usage:log.pylog.logtoptimes\nexamplelog.pylog.log20\ncodebyiswin")
sys.exit()
dic={}
log=Log(sys.argv[1],dic,sys.argv[2])
log.parse()
