python爬虫批量抓取ip代理

发布时间:2019年04月17日 来源:互联网

python爬虫批量抓取ip代理!使用爬虫抓取数据时,经常要用到多个ip代理,防止单个ip访问太过频繁被封禁。

python爬虫批量抓取ip代理

因此写一个python程序来获取ip代理,保存到本地。


python版本:3.6.3


1 #grab ip proxies from xicidaili

 2 import sys, time, re, requests

 3 from multiprocessing.dummy import Pool as ThreadPool

 4 from lxml import etree

 8 #URL = 'http://www.xicidaili.com/wt/' #IP代理 http

 9 RUN_TIME = time.strftime("%Y-%m-%d %H:%M", time.localtime()) #执行时间

10 

11 #用字典存放有效ip代理

12 alive_ip = {'http': [], 'https': []}

13 #多线程

40 else:

44 

45 #解析html文本,获取ip代理

54 data = line.xpath('./td')

55 ip = data[1].xpath('./text()')[0]

56 port = data[2].xpath('./text()')[0]

57 anonymous = data[4].xpath('./text()')[0]

58 ip_type = data[5].xpath('./text()')[0]

59 #过滤掉速度慢和非高匿的ip代理

60 if float(speed[:-1])<1 or float(connect_time[:-1])<1 or anonymous != '高匿':

61 continue

62 iplist.append(ip_type.lower() + '://' + ip + ':' + port)

63 pool.map(test_alive, iplist)

64 

65 #把抓取到的有效ip代理写入到本地

66 def write_txt(output_file):

67 with open(output_file, 'w') as f:

68 f.write('#create time: %s\n\n' % RUN_TIME)

69 f.write('http_ip_pool = \\\n')

70 f.write(str(alive_ip['http']).replace(',', ',\n'))

71 f.write('\n\n')

72 with open(output_file, 'a') as f:

73 f.write('https_ip_pool = \\\n')

74 f.write(str(alive_ip['https']).replace(',', ',\n'))

77 def main():

81 if __name__ == '__main__':

82 try:

83 output_file = sys.argv[1] #第一个参数作为文件名

84 except:

85 output_file = IP_POOL

86 main()

运行程序:


root@c:test$ python get_ip_proxies.py

write successful: ip_pool.py
