大家好，欢迎来到IT知识分享网。
今天博客开始继续更新，谢谢大家对我的关注和支持。这几天一直是在写一个ip代理池的开源项目。通过前几篇的博客，我们可以了解到突破反爬虫机制的一个重要举措就是代理ip。拥有庞大稳定的ip代理，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。（我的新书《Python爬虫开发与项目实战》出版了，大家可以看一下样章）
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'

self.database.commit()

def close(self):
self.cursor.close()
self.database.close()
if __name__=="__main__":

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

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):
'''

: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):
'''

# for result in results:

#这个时候proxys的格式是[{},{},{},{},{}]
return proxys
def deleteOld(self):
'''

: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)

print 'fail ip =%s'%ip
self.sqlHelper.delete(SqliteHelper.tableName,condition)
else:

else:

proxy['speed']=speed
# return proxy

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：
'''
