这两周组里面几位想学习python，于是我们就创建了一个这样的环境和氛围来给大家学习。 昨天在群里，贴了一个需求，就是统计squid访问日志中ip 访问数和url的访问数并排序，不少同学都大体实现了相应的功能，我把我简单实现的贴出来，欢迎拍砖： 日志格式如下： 代码如下: %ts.%03tu %6tr %{X-Forwarded-For}>h %Ss/%03Hs %<st %rm %ru %un %Sh/%<A %mt "%{Referer}>h" "%{User-Agent}>h" %{Cookie}>h 代码如下: 1372776321.285 0 100.64.19.225 TCP_HIT/200 8560 GET http://img1.bitsCN.com/games/0908/19/1549401_3_80x100.jpg - NONE/- image/jpeg "http://www.bitsCN.com/" "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; QQDownload 734; .NET4.0C; .NET CLR 2.0.50727)" pcsuv=0;%20pcuvdata=lastAccessTime=1372776317582;%20u4ad=33480hn;%20c=14arynt;%20uf=1372776310453 代码如下: #!/usr/bin/python # -*- coding: utf-8 -*- import sys from optparse import OptionParser ''' 仅仅是一个关于日志文件的测试，统计处access.log 的ip数目 ''' try: f = open('/data/proclog/log/squid/access.log') except IOError,e: print "can't open the file:%s" %(e) def log_report(field): ''' return the field of the access log ''' if field == "ip": return [line.split()[2] for line in f] if field == "url": return [line.split()[6] for line in f] def log_count(field): ''' return a dict of like {field:number} ''' fields2 = {} fields = log_report(field) for field_tmp in fields: if field_tmp in fields2: fields2[field_tmp] += 1 else: fields2[field_tmp] = 1 return fields2 def log_sort(field,number = 10 ,reverse = True): ''' print the sorted fields to output ''' for v in sorted(log_count(field).iteritems(),key = lambda x:x[1] , reverse = reverse )[0:int(number)]: print v[1],v[0] if __name__ == "__main__": parser =OptionParser(usage="%prog [-i|-u] [-n num | -r]" ,version = "1.0") parser.add_option('-n','--number',dest="number",type=int,default=10,help=" print top line of the ouput") parser.add_option('-i','--ip',dest="ip",action = "store_true",help="print ip information of access log") parser.add_option('-u','--url',dest="url",action = "store_true",help="print url information of access log") parser.add_option('-r','--reverse',action = "store_true",dest="reverse",help="reverse output ") (options,args) = parser.parse_args() if len(sys.argv) < 2: parser.print_help() if options.ip and options.url: parser.error(' -i and -u can not be execute at the same time ') if options.ip : log_sort("ip", options.number , True and options.reverse or False) if options.url: log_sort("url", options.number , True and options.reverse or False) f.close() 效果如下：
