本文实例讲述了Python实现从log日志中提取ip的方法。分享给大家供大家参考,具体如下:
log日志内容如下(myjob.log):
124.90.53.68 - - [05/Feb/2018 11:37:07] "GET /favicon.ico HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:44] "GET / HTTP/1.1" 200 - 61.148.245.145 - - [05/Feb/2018 12:37:44] "GET /apple-touch-icon-120x120-precomposed.png HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:44] "GET /apple-touch-icon-120x120.png HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:45] "GET /apple-touch-icon-precomposed.png HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:45] "GET /apple-touch-icon.png HTTP/1.1" 404 - 61.148.245.145 - - [05/Feb/2018 12:37:45] "GET /static/favicon.ico HTTP/1.1" 200 - 101.226.33.218 - - [05/Feb/2018 13:07:39] "GET / HTTP/1.1" 200 - 101.226.33.219 - - [05/Feb/2018 13:09:46] "GET / HTTP/1.1" 200 - 101.226.33.219 - - [05/Feb/2018 13:09:46] "GET /static/youkulogo.png HTTP/1.1" 200 - 101.226.33.219 - - [05/Feb/2018 13:09:46] "GET /static/iqiyi.png HTTP/1.1" 200 - 101.226.33.219 - - [05/Feb/2018 13:09:46] "GET /static/qqlogo.png HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:45] "GET / HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:47] "GET /static/youkulogo.png HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:48] "GET /static/qqlogo.png HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:48] "GET /static/iqiyi.png HTTP/1.1" 200 - 124.202.223.62 - - [05/Feb/2018 14:29:49] "GET /static/favicon.ico HTTP/1.1" 200 -
提取ip:
# encoding: utf-8 import sys reload(sys) sys.setdefaultencoding('utf-8') import pandas as pd import re import time import requests time1=time.time() ######函数功能:能够提取ip地址,并且去重################ def read_file(input_file_name,output_file_name): _fLog = open(input_file_name) sep = '\n' ip_list=[] for each in _fLog: ip=re.findall(r'(?<![\.\d])(?:\d{1,3}\.){3}\d{1,3}(?![\.\d])',str(each),re.S) ip_list.append(ip[0]) # 列表去重:通过set方法进行处理 ids = list(set(ip_list)) print "共解析ip个数:%s "% len(ids) ##写出数据到本地 # 设置输出文件路径 out = open(output_file_name, "a") # out.write("ip" + sep) for each in ids: print each out.write(each + sep) ##关闭连接 out.close() _fLog.close() print "ip提取完毕~~" ####主函数################ if __name__ == '__main__': input_file_name = "C:/myjob.log" output_file_name = "c:/myjob.txt" read_file(input_file_name, output_file_name) time2 = time.time() print u'总共耗时:' + str(time2 - time1) + 's'
运行结果:
共解析ip个数:5
61.148.245.145
124.90.53.68
124.202.223.62
101.226.33.219

ip提取完毕~~
