统计某个ip访问某个url的次数答案

【问题标题】：Count how many times an ip has accessed a url统计某个ip访问某个url的次数
【发布时间】：2022-11-16 03:56:16
【问题描述】：

我可以从大量日志文件中打印 ip 和 url，但我需要列出 ip 访问该 url 的次数。我已经做了一些关于将日志放入数据库的研究，但我特别需要在 Python 中完成所有这些工作。非常感谢任何帮助。

到目前为止我的代码：

#!/usr/bin/python3
count = 0
log = open("access.log-20201019", "r")
arr = []
frequency_array = []

for i in log.readlines():
        ip = i[0:14]
        ip2 = ip.split(' ')
        ip3 = ip2[0]
        #print(ip3)
        url =i[53:87]
        url2 = url.split()
        url3 = url2[0]
        print(ip3,url3)

我能够运行我当前的代码，但会为同一个 ip 多次输出 ip 和 url。我只想要一个 ip 访问某个 url 的次数。

【问题讨论】：

您可以在“collections.Counter”对象中提供 IP 和 URL 的元组。
ip = i[0:14] 不够大，一个IP可以15个字符长。为什么不只是ip = i.split()[0]？

【解决方案2】：

我会使用 python 字典，使用 IP 地址作为键。每次遇到 IP 时，检查 ip 是否存在于密钥列表中。它会是这样的：

如果 k 在 dict.keys(): dict[k] += 1

否则：字典[k] = 1

或者您可以使用 dict.setdefault() 并将所有设置为 1 并在每次找到 IP 时添加
