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：
import sys
class Log:
def __init__(self, filename,dic,count):
self.filename = filename
self.dic=dic
self.count=count
def parse(self):

f=file(self.filename)
while True:
line=f.readline()
if len(line)==0:
break
ip=line.split(' ')
if ip[0] in dic:
self.dic[ip[0]]=self.dic[ip[0]]+1
else:
self.dic[ip[0]]=i
soredic=sorted(self.dic.items(), key=lambda d:d[1],reverse=True)
counts=0;
for item in soredic:
if counts==int(self.count):
break
print("IP:%s Total Times: %s"%(item[0],item[1]))
counts=counts+1
f.close()
if __name__=="__main__":
if len(sys.argv)<3:
print('usage:log.py log.log toptimes\nexample log.py log.log 20\ncode by iswin')
sys.exit()
