python扫描proxy并获取可用代理ip的实例
from:https://www.jb51.net/article/120480.htm
下面小编就为大家带来一篇python扫描proxy并获取可用代理ip的实例。小编觉得挺不错的,现在就分享给大家,也给大家做个参考。一起跟随小编过来看看吧
今天咱写一个挺实用的工具,就是扫描并获取可用的proxy
首先呢,我先百度找了一个网站:http://www.xicidaili.com 作为例子
这个网站里公布了许多的国内外可用的代理的ip和端口
我们还是按照老样子进行分析,就先把所有国内的proxy扫一遍吧
点开国内部分进行审查发现,国内proxy和目录为以下url:
这个x差不多两千多页,那么看来又要线程处理了。。。
老样子,我们尝试是否能直接以最简单的requests.get()获取内容
返回503,那么我们加一个简单的headers
返回200,成咯
好了我们先进行网页内容分析并获取想要的内容
我们发现,包含ip信息的内容在<tr>标签内,于是我们就能很方便的用bs进行获取标签内容
但是我们随之又发现,ip、端口、协议的内容分别在提取的<tr>标签的第2,3,6三个<td>标签内
r = requests.get(url = url,headers = headers) soup = bs(r.content,"html.parser") data = soup.find_all(name = 'tr',attrs = {'class':re.compile('|[^odd]')}) for i in data: soup = bs(str(i),'html.parser') data2 = soup.find_all(name = 'td') ip = str(data2[1].string) port = str(data2[2].string) types = str(data2[5].string).lower() proxy = {} proxy[types] = '%s:%s'%(ip,port)
这样,我们每次循环都能生成对应的proxy字典,以便我们接下来验证ip可用性所使用
字典这儿有个注意点,我们有一个将types变为小写的操作,因为在get方法中的proxies中写入的协议名称应为小写,而网页抓取的是大写的内容,所以进行了一个大小写转换
那么验证ip可用性的思路呢
很简单,我们使用get,加上我们的代理,请求网站:
这是一个神奇的网站,能返回你的外网ip是什么
url = 'http://1212.ip138.com/ic.asp'
r = requests.get(url = url,proxies = proxy,timeout = 6)
这里我们需要加上timeout去除掉那些等待时间过长的代理,我设置为6秒
我们以一个ip进行尝试,并且分析返回的页面
返回的内容如下:
<html>
<head>
<meta xxxxxxxxxxxxxxxxxx>
<title> 您的IP地址 </title>
</head>
<body style="margin:0px"><center>您的IP是:[xxx.xxx.xxx.xxx] 来自:xxxxxxxx</center></body></html>
那么我们只需要提取出网页内[]的内容即可
如果我们的代理可用,就会返回代理的ip
(这里会出现返回的地址还是我们本机的外网ip的情况,虽然我也不是很清楚,但是我把这种情况排除,应该还是代理不可用)
那么我们就能进行一个判断,如果返回的ip和proxy字典中的ip相同,则认为这个ip是可用的代理,并将其写入文件
我们的思路就是这样,最后进行queue和threading线程的处理即可
上代码:
#coding=utf-8
import requests
import re
from bs4 import BeautifulSoup as bs
import Queue
import threading
class proxyPick(threading.Thread):
def __init__(self,queue):
threading.Thread.__init__(self)
self._queue = queue
def run(self):
while not self._queue.empty():
url = self._queue.get()
proxy_spider(url)
def proxy_spider(url):
headers = {
.......
}
r = requests.get(url = url,headers = headers)
soup = bs(r.content,"html.parser")
data = soup.find_all(name = 'tr',attrs = {'class':re.compile('|[^odd]')})
for i in data:
soup = bs(str(i),'html.parser')
data2 = soup.find_all(name = 'td')
ip = str(data2[1].string)
port = str(data2[2].string)
types = str(data2[5].string).lower()
proxy = {}
proxy[types] = '%s:%s'%(ip,port)
try:
proxy_check(proxy,ip)
except Exception,e:
print e
pass
def proxy_check(proxy,ip):
url = 'http://1212.ip138.com/ic.asp'
r = requests.get(url = url,proxies = proxy,timeout = 6)
f = open('E:/url/ip_proxy.txt','a+')
soup = bs(r.text,'html.parser')
data = soup.find_all(name = 'center')
for i in data:
a = re.findall(r'\[(.*?)\]',i.string)
if a[0] == ip:
#print proxy
f.write('%s'%proxy+'\n')
print 'write down'
f.close()
#proxy_spider()
def main():
queue = Queue.Queue()
for i in range(1,2288):
queue.put('http://www.xicidaili.com/nn/'+str(i))
threads = []
thread_count = 10
for i in range(thread_count):
spider = proxyPick(queue)
threads.append(spider)
for i in threads:
i.start()
for i in threads:
i.join()
print "It's down,sir!"
if __name__ == '__main__':
main()
这样我们就能把网站上所提供的能用的代理ip全部写入文件ip_proxy.txt文件中了
以上这篇python扫描proxy并获取可用代理ip的实例就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持脚本之家。
