Python 多线程爬取西刺代理

西刺代理是一个国内IP代理，由于代理倒闭了，所以我就把原来的代码放出来供大家学习吧。

首先找到所有的tr标签，与class="odd"的标签，然后提取出来。

然后再依次找到tr标签里面的所有td标签，然后只提取出里面的[1,2,5,9]这四个标签的位置，其他的不提取。

最后可以写出提取单一页面的代码，提取后将其保存到文件中。

import sys,re,threading
import requests,lxml
from queue import Queue
import argparse
from bs4 import BeautifulSoup

head = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.100 Safari/537.36"}

if __name__ == "__main__":
    ip_list=[]
    fp = open("SpiderAddr.json","a+",encoding="utf-8")
    url = "https://www.blib.cn/url/xcdl.html"
    request = requests.get(url=url,headers=head)
    soup = BeautifulSoup(request.content,"lxml")
    data = soup.find_all(name="tr",attrs={"class": re.compile("|[^odd]")})
    for item in data:
        soup_proxy = BeautifulSoup(str(item),"lxml")
        proxy_list = soup_proxy.find_all(name="td")
        for i in [1,2,5,9]:
            ip_list.append(proxy_list[i].string)
        print("[+] 爬行列表: {} 已转存".format(ip_list))
        fp.write(str(ip_list) + '\n')
        ip_list.clear()

爬取后会将文件保存为 SpiderAddr.json 格式。

最后再使用另一段代码，将其转换为一个SSR代理工具直接能识别的格式，{'http': 'http://119.101.112.31:9999'}

import sys,re,threading
import requests,lxml
from queue import Queue
import argparse
from bs4 import BeautifulSoup

if __name__ == "__main__":
    result = []
    fp = open("SpiderAddr.json","r")
    data = fp.readlines()

    for item in data:
        dic = {}
        read_line = eval(item.replace("\n",""))
        Protocol = read_line[2].lower()
        if Protocol == "http":
            dic[Protocol] = "http://" + read_line[0] + ":" + read_line[1]
        else:
            dic[Protocol] = "https://" + read_line[0] + ":" + read_line[1]
        result.append(dic)
        print(result)

完整多线程版代码如下所示。
