python如何开源IP代理池？

发布时间：2019年12月11日来源：互联网

在爬虫工作中将起到重要的作用,但是从成本的角度来说，一般稳定的ip池都很贵，因此我这个开源项目的意义就诞生了，爬取一些代理网站提供的免费ip(虽然70%都是不好使的,但是扛不住量大，网站多)，检测有效性后存储到数据库中，同时搭建一个http服务器，提供一个api接口，供大家的爬虫程序调用。

好了，废话不多说，咱们进入今天的主题，讲解一下我写的这个开源项目IPProxys。

　　下面是这个项目的工程结构:

　　 api包:主要是实现http服务器，提供api接口(通过get请求,返回json数据)

　　 data文件夹:主要是数据库文件的存储位置和qqwry.dat(可以查询ip的地理位置)

　　 db包：主要是封装了一些数据库的操作

　　 spider包：主要是爬虫的核心功能，爬取代理网站上的代理ip

　　 test包：测试一些用例，不参与整个项目的运行

　　 util包：提供一些工具类。IPAddress.py查询ip的地理位置

　　 validator包:用来测试ip地址是否可用

　　 config.py：主要是配置信息(包括配置ip地址的解析方式和数据库的配置)

　　接下来讲一下关键代码:

　首先说一下apiServer.py:

#coding:utf-8

'''

定义几个关键字，count types,protocol,country,area,

'''

import urllib

from config import API_PORT

from db.SQLiteHelper import SqliteHelper

__author__ = 'Xaxdus'

import BaseHTTPServer

import json

import urlparse

# keylist=['count', 'types','protocol','country','area']

class WebRequestHandler(BaseHTTPServer.BaseHTTPRequestHandler):

def do_GET(self):

"""

dict={}

parsed_path = urlparse.urlparse(self.path)

try:

query = urllib.unquote(parsed_path.query)

print query

if query.find('&')!=-1:

params = query.split('&')

for param in params:

dict[param.split('=')[0]]=param.split('=')[1]

else:

dict[query.split('=')[0]]=query.split('=')[1]

str_count=''

conditions=[]

for key in dict:

if key =='count':

str_count = 'lIMIT 0,%s'% dict[key]

if key =='country' or key =='area':

conditions .append(key+" LIKE '"+dict[key]+"%'")

elif key =='types' or key =='protocol' or key =='country' or key =='area':

conditions .append(key+"="+dict[key])

if len(conditions)>1:

conditions = ' AND '.join(conditions)

else:

conditions =conditions[0]

sqlHelper = SqliteHelper()

result = sqlHelper.select(sqlHelper.tableName,conditions,str_count)

# print type(result)

# for r in result:

# print r

print result

data = json.dumps(result)

self.send_response(200)

self.end_headers()

self.wfile.write(data)

except Exception,e:

print e

self.send_response(404)

if __name__=='__main__':

server = BaseHTTPServer.HTTPServer(('0.0.0.0',API_PORT), WebRequestHandler)

server.serve_forever()

　　从代码中可以看出是对参数的解析，参数包括 count(数量), types(模式),protocol(协议),country(国家),area(地区),(

types类型(0高匿名，1透明)，protocol(0 http,1 https http),country(国家),area(省市))

例如访问http://127.0.0.1:8000/?count=8&types=0.返回json数据。如下图所示:

　　接着说一下SQLiteHelper.py(主要是对sqlite的操作):

#coding:utf-8

from config import DB_CONFIG

from db.SqlHelper import SqlHelper

__author__ = 'Xaxdus'

import sqlite3

class SqliteHelper(SqlHelper):

tableName='proxys'

def __init__(self):

'''

建立数据库的链接

:return:

'''

self.database = sqlite3.connect(DB_CONFIG['dbPath'],check_same_thread=False)

self.cursor = self.database.cursor()

#创建表结构

self.createTable()

def createTable(self):

self.cursor.execute("create TABLE IF NOT EXISTS %s (id INTEGER PRIMARY KEY ,ip VARCHAR(16) NOT NULL,"

"port INTEGER NOT NULL ,types INTEGER NOT NULL ,protocol INTEGER NOT NULL DEFAULT 0,"

"country VARCHAR (20) NOT NULL,area VARCHAR (20) NOT NULL,updatetime TimeStamp NOT NULL DEFAULT (datetime('now','localtime')) ,speed DECIMAL(3,2) NOT NULL DEFAULT 100)"% self.tableName)

self.database.commit()

def select(self,tableName,condition,count):

'''

:param tableName: 表名

:param condition: 条件包含占位符

:param value: 占位符所对应的值(主要是为了防注入)

:return:

'''

command = 'SELECT DISTINCT ip,port FROM %s WHERE %s ORDER BY speed ASC %s '%(tableName,condition,count)

self.cursor.execute(command)

result = self.cursor.fetchall()

return result

def selectAll(self):

self.cursor.execute('SELECT DISTINCT ip,port FROM %s ORDER BY speed ASC '%self.tableName)

result = self.cursor.fetchall()

return result

def selectCount(self):

self.cursor.execute('SELECT COUNT( DISTINCT ip) FROM %s'%self.tableName)

count = self.cursor.fetchone()

return count

def selectOne(self,tableName,condition,value):

'''

:param tableName: 表名

:param condition: 条件包含占位符

:param value: 占位符所对应的值(主要是为了防注入)

:return:

'''

self.cursor.execute('SELECT DISTINCT ip,port FROM %s WHERE %s ORDER BY speed ASC'%(tableName,condition),value)

result = self.cursor.fetchone()

return result

def update(self,tableName,condition,value):

self.cursor.execute('UPDATE %s %s'%(tableName,condition),value)

self.database.commit()

def delete(self,tableName,condition):

'''

:param tableName: 表名

:param condition: 条件

:return:

'''

deleCommand = 'DELETE FROM %s WHERE %s'%(tableName,condition)

# print deleCommand

self.cursor.execute(deleCommand)

self.commit()

def commit(self):

self.database.commit()

def insert(self,tableName,value):

proxy = [value['ip'],value['port'],value['type'],value['protocol'],value['country'],value['area'],value['speed']]

# print proxy

self.cursor.execute("INSERT INTO %s (ip,port,types,protocol,country,area,speed)VALUES (?,?,?,?,?,?,?)"% tableName

,proxy)

def batch_insert(self,tableName,values):

for value in values:

if value!=None:

self.insert(self.tableName,value)

self.database.commit()

def close(self):

self.cursor.close()

self.database.close()

if __name__=="__main__":

s = SqliteHelper()

print s.selectCount()[0]

# print s.selectAll()

　　HtmlPraser.py(主要是对html进行解析):

　　使用lxml的xpath进行解析

#coding:utf-8

import datetime

from config import QQWRY_PATH, CHINA_AREA

from util.IPAddress import IPAddresss

from util.logger import logger

__author__ = 'Xaxdus'

from lxml import etree

def AuthCountry(self,addr):

'''

:param addr:

:return:

　　IPAddresss.py(通过读取纯真qqwry.dat,对ip地址进行定位)，读取的方式可以参考:http://ju.outofmemory.cn/entry/85998;https://linuxtoy.org/archives/python-ip.html

def dump(self, first , last):

　　最后看一下validator.py，由于使用的是python2.7,所以要使用协程采用了gevent:

#coding:utf-8

import datetime

from gevent.pool import Pool

import requests

import time

from config import TEST_URL

import config

from db.SQLiteHelper import SqliteHelper

from gevent import monkey

monkey.patch_all()

__author__ = 'Xaxdus'

class Validator(object):

def __init__(self):

self.detect_pool = Pool(config.THREADNUM)

def __init__(self,sqlHelper):

self.detect_pool = Pool(config.THREADNUM)

self.sqlHelper =sqlHelper

def run_db(self):

'''

从数据库中检测

:return:

'''

try:

#首先将超时的全部删除

self.deleteOld()

#接着将重复的删除掉

#接着检测剩余的ip,是否可用

results = self.sqlHelper.selectAll()

self.detect_pool.map(self.detect_db,results)

return self.sqlHelper.selectCount()#返回最终的数量

except Exception,e:

print e

return 0

def run_list(self,results):

'''

这个是先不进入数据库，直接从集合中删除

:param results:

:return:

'''

# proxys=[]

# for result in results:

proxys = self.detect_pool.map(self.detect_list,results)

#这个时候proxys的格式是[{},{},{},{},{}]

return proxys

def deleteOld(self):

'''

删除旧的数据

:return:

'''

condition = "updatetime<'%s'"%((datetime.datetime.now() - datetime.timedelta(minutes=config.MAXTIME)).strftime('%Y-%m-%d %H:%M:%S'))

self.sqlHelper.delete(SqliteHelper.tableName,condition)

def detect_db(self,result):

'''

:param result: 从数据库中检测

:return:

'''

start = time.time()

try:

if not r.ok:

condition = "ip='"+ip+"' AND "+'port='+port

print 'fail ip =%s'%ip

self.sqlHelper.delete(SqliteHelper.tableName,condition)

else:

speed = round(time.time()-start, 2)

self.sqlHelper.update(SqliteHelper.tableName,'SET speed=? WHERE ip=? AND port=?',(speed,ip,port))

print 'success ip =%s,speed=%s'%(ip,speed)

except Exception,e:

print 'fail ip =%s'%ip

self.sqlHelper.delete(SqliteHelper.tableName,condition)

def detect_list(self,proxy):

# for proxy in proxys:

try:

if not r.ok:

print 'fail ip =%s'%ip

proxy = None

else:

speed = round(time.time()-start,2)

print 'success ip =%s,speed=%s'%(ip,speed)

proxy['speed']=speed

# return proxy

except Exception,e:

print 'fail ip =%s'%ip

proxy = None

return proxy

# return proxys

if __name__=='__main__':

# v = Validator()

# results=[{'ip':'192.168.1.1','port':80}]*10

# results = v.run(results)

# print results

pass

最后咱们看一下运行效果: 切换到工程目录下,cmd中执行python IPProxys.py：

　　这个时候咱们在浏览器中输入请求,就会返回响应的结果:　　　　　　

　　执行流程是每隔半小时检测一下数据库中ip地址的有效性，删除无效的代理ip。如果ip地址数量少于一个数值，爬虫将会启动，进行新一轮的爬取。当然检测时间和数据量都可以在config.py中配置。咱们看一下config.py的部分代码,大家就明白了：

'''
