小的最近一直在准备比赛，不断地在各大招聘网站上薅羊毛，然而现在爬虫很不受待见啊，想爬得快一点就会被封。(+_+)?
最尴尬的是，我在爬赶集网上的招聘信息的时候，爬上150条一定会把我封掉，每次都是这个数字
真是丧心病狂的设定(╯‵□′)╯︵┻━┻
被逼无奈，只能临时先搭建一个简陋的ip池这样子，才能维持的了生活。ε=ε=ε=(~￣▽￣)~
首先我们找一家ip代理网站来薅羊毛（注意不要爬太多了，大家都是要吃饭的嘛，做人留一面，日♂后好相见(・∀・(・∀・(・∀・*)，这是俺最近被别人告♂诫的）
国内高匿免费HTTP代理IP__第1页国内高匿www.xicidaili.com
爬取ip地址，端口和类型三个就行了
用selenium比较方便和直观U•ェ•*U
思路
1.我们先把爬取到的ip保存下来，然后在挨个验证是否可用
2.把验证完可用的IP存入数据库
3.在scrapy 中使用代理ip
上代码
from selenium import webdriverimport timefrom ip_test.__init__ import *import pymysqlimport randomimport requestsfrom multiprocessing import Poolclass Getips: def __init__(self): self.connect = pymysql.connect(MYSQL_HOST, MYSQL_ROOT, MYSQL_PASSWORD, MYSQL_DATABASE) self.cursor = self.connect.cursor() # 选定数据库 def GetUserAgent(self): user_agents = [ "Mozilla/4.0 (compatible;

相信你们能看懂，虽然写的乱了点╰(￣ω￣ｏ)
数据库语句和俺以前用的一样
MYSQL_DATABASE='spider'MYSQL_ROOT='root'MYSQL_PASSWORD='123'USE='use spider'TABLE='ip_s1'TABLE1="tmp_ip_s1"DROP="drop table if exists %s"%TABLEDROP1="drop table if exists %s"%TABLE1CREATE='create table %s(category varchar(255) ,ip varchar(255)Not null)'%TABLECREATE1='create table %s(category varchar(255) ,ip varchar(255)Not null)'%TABLE1SAVEIN='insert into '+TABLE+' (category,ip) values(%s,%s)'SAVEIN1='insert into '+TABLE1+' (category,ip) values(%s,%s)'SQL="select * from %s"%TABLESQL1="select * from %s"%TABLE1tarURL = "http://www.baidu.com/"TIME_DIFFERENCE=5
看看效果
这是总共爬得的ip地址
这是能用的，其实也不少啦(●ˇ∀ˇ●)
经过我在赶集网上的实验，这些ip.......能用，就是效率太低啦d=====(￣▽￣*)b
十几个url只能爬三条啊⊙﹏⊙∥
不过好歹能用啦，下回爬多一点试试
这是一个简陋版，其实还可以用多线程和其他的方法，等我有发现了就告诉大家(ง •_•)ง |
