python - http 检查 python

Question

在这里学习python，我想看看有没有人在我的本地运行web服务器网络，使用此代码，但它在控制台中给了我很多错误。

#!/usr/bin/env python

import httplib
last = 1
while last <> 255:
        url = "10.1.1." + "last"
        connection = httplib.HTTPConnection("url", 80)
        connection.request("GET","/")
        response = connection.getresponse()
        print (response.status)
        last = last + 1

Answer 1

我确实建议将 while 循环更改为更惯用的 for 循环，并处理异常:

#!/usr/bin/env python

import httplib
import socket


for i in range(1, 256):
    try:
        url = "10.1.1.%d" % i
        connection = httplib.HTTPConnection(url, 80)
        connection.request("GET","/")
        response = connection.getresponse()
        print url + ":", response.status
    except socket.error:
        print url + ":", "error!"
