python多线程爬取西刺代理的示例代码

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,threadingimport requests,lxmlfrom queue import Queueimport argparsefrom bs4 import BeautifulSouphead = {'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,threadingimport requests,lxmlfrom queue import Queueimport argparsefrom bs4 import BeautifulSoupif __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。

import sys,re,threadingimport requests,lxmlfrom queue import Queueimport argparsefrom bs4 import BeautifulSouphead = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.100 Safari/537.36'}class AgentSpider(threading.Thread): def __init__(self,queue): threading.Thread.__init__(self) self._queue = queue def run(self): ip_list=[] fp = open('SpiderAddr.json','a+',encoding='utf-8') while not self._queue.empty(): url = self._queue.get() try: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() except Exception:passdef StartThread(count): queue = Queue() threads = [] for item in range(1,int(count)+1): url = 'https://www.xicidaili.com/nn/{}'.format(item) queue.put(url) print('[+] 生成爬行链接 {}'.format(url)) for item in range(count): threads.append(AgentSpider(queue)) for t in threads: t.start() for t in threads: t.join()# 转换函数def ConversionAgentIP(FileName): result = [] fp = open(FileName,'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) return resultif __name__ == '__main__': parser = argparse.ArgumentParser() parser.add_argument('-p','--page',dest='page',help='指定爬行多少页') parser.add_argument('-f','--file',dest='file',help='将爬取到的结果转化为代理格式 SpiderAddr.json') args = parser.parse_args() if args.page: StartThread(int(args.page)) elif args.file: dic = ConversionAgentIP(args.file) for item in dic: print(item) else: parser.print_help()
