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" 200 10 "-" "-"171.104.119.22 - - [06/Aug/2014:08:55:01 +0800] "GET / HTTP/1.0" 200 10 "-" "-"27.31.238.242 - - [06/Aug/2014:09:43:19 +0800] "GET / HTTP/1.0" 200 10 "-" "-"218.65.202.131 - - [06/Aug/2014:10:33:59 +0800] "GET / HTTP/1.0" 200 10 "-" "-"

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):    i=1    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()  dic={}  log=Log(sys.argv[1],dic,sys.argv[2])  log.parse()
