Use Python to crawl available proxy IP addresses and python to crawl proxy ip addresses
Preface
Take the latest free proxy IP website as an example: http://www.xicidaili.com/nn /. Many IP addresses cannot be used.
So I wrote a script in Python, which can detect available proxy IP addresses.
The script is as follows:

This article mainly introduces seven methods for JS to obtain Client IP addresses, MAC addresses, and host names. JS itself does not support obtaining IP addresses and other information. This article uses other methods to achieve this, if you need a friend, you can refer to the small program that is engaged in JS (javascript) to obtain the Client IP address today
so-called virtual address technology. That is, an intermediate layer (Virtual Address) is added between the user process and the actual physical memory, so that the user process can only access the virtual address, and the implementation of the physical address conversion is handed over to the operating system.
Features of virtual addresses:
1. When a process is created,
(1) The OS allocates a 4G virtual address space for each process, and each proce
How to replace relative addresses with absolute addresses in batches. . Then, you can do this: if your url link is relative to the path "static/mapi.css", you want to replace it with the absolute path "http://dev.baidu.com/wiki/static/map/cloud/static/mapi.css ". Then, you can do this:
Write a php file and enter the URL to be replaced.
This code means replacing # BASE_URL # with a http://api.map.baidu.com/

Python generates random mac addresses. python generates mac addresses.
This example describes how to generate a random mac address using python. Share it with you for your reference. The specific implementation method is as follows:
#! /Usr/bin/pythonimport randomdef randomMAC (): mac = [0x52, 0x54, 0x00, random. randint (0x00, 0x7f), random. randint (0x00, 0xff), random. randint (0x00, 0xff)] return ':'.

Today, a friend asked me how to allow access from only the specified IP address and prohibit access from other ip addresses by default. what I previously shared in my website is how to restrict access from the specified ip address, you can refer to the core function code as follows:
/*** Check whether the Accessed ip address is a specified allowed ip address * Enter description here... */function check_ip () {$ ALLOWED_IP = array ('2017. 168. 2. * ',
