老李性能测试分享：可以没事代理刷榜赚外快了，poptest这是让你快速致富啊

         最近学员不断面试，不时听到令人惊喜的消息，类似应届专科毕业生获得7k月薪，小美女应聘月薪11k等等，看到学员开心的笑容令人开心。在POPTEST学习很辛苦，每天学员起早贪黑，回家10点正常，11,12点回家不稀奇，学员也有自己的生活，有的时候会让我去给他们刷榜，其实学员在前面的学习中已经有了基础“这样的脚本，所以我这里通过爬虫技术爬下代理ip，然后采用多进程的方法来访问www.poptest.cn，实现利用代理ip地址访问网站，间接说明如何帮学员刷榜，~_~!!!!!，脚本如下：

    proxy = []

    for i in range(1,12):

        r = requests.get('http://www.xicidaili.com/nt/{0}'.format(i),headers= header)

 

        html = r.text

        soup = BeautifulSoup(html)

        table = soup.find('table', attrs={'id': 'ip_list'})

        tr = table.find_all('tr')[1:]

        #解析得到代理ip的地址，端口，和类型

        for item in tr:

            tds =  item.find_all('td')

            temp_dict = {}

            kind = tds[6].get_text().lower()

            if 'http' in kind:

                temp_dict['http'] = "http://{0}:{1}".format(tds[2].get_text(), tds[3].get_text())

            if 'https' in kind:

                temp_dict['https'] = "https://{0}:{1}".format(tds[2].get_text(), tds[3].get_text())

 

            proxy.append(temp_dict)

    return proxy

    final = input() # 输入数字代表要获取多少次代理ip

    while t< final:

        t += 1

        proxies = getProxyIp() # 获取代理ip网站上的前12页的ip

        # 为了爬取的代理ip不浪费循环5次使得第一次的不能访问的ip尽可能利用

        for i in range(5):

            i += 1

            # 多进程代码开了32个进程

            pool = multiprocessing.Pool(processes=32)

            results = []

            for i in range(len(proxies)):

                results.append(pool.apply_async(brash,(proxies[i],)))
