1.把日志状态码为200得请求记录下来

记录信息（ip,访问时间,请求资源）

封装函数再次调用，健壮性try except

#coding=utf-8

import re

def  aclog(path,putpath):

    result=""

    with open(path,"r")  as fp:

        lines=fp.readlines()

        for line in lines:

            if "200" in line:

                

                ip=re.search(r"(\d{1,3}\.){3}\d{1,3}",line).group()

                time=re.search(r"\[.*\]",line).group()

                url=re.search(r"GET.*(200)",line).group()[:-3]

                result=ip+time+url+"\n"

                with open(putpath,"a+") as fp1:

                    fp1.write(result)

        

aclog("e:\\accesslog.txt","e:\\aclog.txt")

 

另一种方法：使用split

#encoding=utf-8

def AnalysisLog(filenameget,filenameput):

    try:

        with open(filenameget) as f:

            as1=[i.split() for i in f]

        as2=[[i[0],i[3],i[6]] for i in as1 if i[8].startswith("2")]

        with open(filenameput,"w") as f:

            f.writelines(["".join([" ".join(i),"\n"]) for i in as2])

        return "success!"

    except Exception,e:

        return "failed!",str(e)

 

if __name__=="__main__":

    filenameget=ur"e:\\get.txt"

    filenameput=ur"e.\\put.txt"

    print AnalysisLog(filenameget,filenameput)

在方法二基础上改善

#encoding=utf-8

def AnalysisLog(filenameget,filenameput):

    result=""

    try:

        with open(filenameget) as f:

            for line in f.readlines():

                i=line.split()

                if "200" in line:

                    result+=i[0]+i[3]+i[6]+"\n"

            

        

        with open(filenameput,"w") as f:

            f.write(result)

        return "success!"

    except Exception,e:#

        return "failed!",str(e)

 

if __name__=="__main__":

    filenameget=ur"e:\\accesslog.txt"

    filenameput=ur"e:\\put.txt"

    print AnalysisLog(filenameget,filenameput)
