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 toptimesnexample log.py log.log 20ncode by iswin') sys.exit() dic={} log=Log(sys.argv[1],dic,sys.argv[2]) log.parse()
