python实战，

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+" "
                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)," "]) 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]+" "
            
        
        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)
