通過爬蟲實現xici可以使用的代理IP 端口

主要代碼：

#coding:utf8

    def get_ip_list(self):
        # print(self.page)

            data = list(line)
            # print(data)
            flag = self.is_available(data[1],data[2])
            if flag == 1:
                print(" {0} {1} {2} 可以使用 ".format(data[1],data[2],data[3]))

if __name__ == "__main__":
    xici = getXici()
    xici.get_page()
    xici.get_ip_list()
