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：

http://www.xicidaili.com/nn/x

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：

http://1212.ip138.com/ic.asp

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-8import 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
passdef 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()
