python日志处理

第一次用python处理日志感受到了与C的差距。

日志如下：

要求：取出php请求并取出act行为（没有则忽略）并计算相同请求的平均时间

例如：【/api/liver_msg.php?act=liver_center】【/live/msg_detail.php?】

python代码：

List = []   # url
List1 = []  # time
dictt = {}  # 存储
List4 = []  # 行号

def func(a, b):
    time = 0.00
    for num in range(len(b)):
        time += float(a[b[num]])   # 时间字符串浮点数化累加
    dictt[List[0]] = time/len(b)   # 时间均值及存储到字典

for url in open("url11.txt", "r").readlines():
    le = url.find(" ")
    url = url[le+1:]  # 去除IP
    le1 = url.find('"')
    url = url[:le1] + url[le1+1:]  # 去除前"
    if ".php" in url:
        if "act" not in url:  # [0.023 "/live/msg_detail.php?id=20&oid=1051868"] 无act
            le2 = url.find("?")
            url = url[:le2+1]
        else:
            le4 = url.find("act")
            tmp = url[le4:]
            if len(tmp) < 7:   # [0.159 "/live/detail_new.php?id=120&act="]去除act为空
                le5 = url.find("?")
                url = url[:le5+1]
            else:
                le3 = url.find("&")  # [0.040 "/search/query.php?act=idx_ifr_v1_new&md=]
                url = url[:le3]
        len1 = url.find(" ")
        url1 = url[len1 + 1:]  # 去掉文本中的空格
        url2 = url[0:len1]
        List.append(url1)  # url
        List1.append(url2)  # 时间

while List:
    #Listt = List[:]
    List4.append(0)  # 每次取元素一为基准
    for y in range(1, len(List)):
        if List[0] == List[y]:    # 重复计数
            List4.append(y)  # 追加行数
    func(List1, List4)

    List5 = List[:]
    List6 = List1[:]  # 避免【list index out of range】 这里使用副本取值
    for x in range(len(List4)):
        List.remove(List5[List4[x]])
        List1.remove(List6[List4[x]])
    List4 = []

print(dictt, end="")

结果：

Process finished with exit code 0

c代码+python代码：

/*
1.awk '{print $2,$3}' url.txt > url23.txt 【取出2，3列】-时间和url
2.过滤杂项，生成url_change.txt 【去除杂项】
3.test.py 【去重求均值】
