篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了怎么判断百度网盘分享连接已经失效?有那么简单吗?java+python相关的知识,希望对你有一定的参考价值。
我不知道现在有多少人在用网盘搜索引擎,但就去转盘网来说本人倾注了很多的心血,现在使用的人数也还可以,网盘资源都有个通病,那就是资源可能失效,但很多引擎都没有做失效判断,尤其是一些google自定义的引擎,技术含量不高,站长也就花心思赚钱,很少考虑用户体验。这篇文章是文人又一篇技术公开博客,之前本人已经公开了去转盘
网的几乎所有的技术细节,这一篇继续补充:
首先做个回顾:百度网盘爬虫 java分词算法 数据库自动备份 代理服务器爬取 邀请好友注册
ing:utf-8 """ @author:haoning @create time:2015.8.5 """ from __future__ import division # 精确除法 from Queue import Queue from __builtin__ import False from _sqlite3 import SQLITE_ALTER_TABLE from collections import OrderedDict import copy import datetime import json import math import os import random import platform import re import threading, errno, datetime import time import urllib2 import mysqldb as mdb DB_HOST = ‘127.0.0.1‘ DB_USER = ‘root‘ DB_PASS = ‘root‘ def gethtml(url): try: print "url",url req = urllib2.Request(url) response = urllib2.urlopen(req,None,8) #在这里应该加入代理 html = response.read() return html except Exception,e: print "e",e if __name__ == ‘__main__‘: while 1: #url=‘http://pan.baidu.com/share/link?uk=1813251526&shareid=540167442‘ url="http://pan.baidu.com/s/1qXQD2Pm" html=gethtml(url) print html
结果:e HTTP Error 403: Forbidden,这就是说,度娘他是反爬虫的,之后看了很多网站,一不小心试了下面的链接:
http://pan.baidu.com/share/link?uk=1813251526&shareid=540167442
if __name__ == ‘__main__‘: while 1: url=‘http://pan.baidu.com/share/link?uk=1813251526&shareid=540167442‘ #url="http://pan.baidu.com/s/1qXQD2Pm" html=gethtml(url) print html
结果:<title>百度云 网盘-链接不存在</title>,你懂的,有这个的必然已经失效,看来度娘没有反爬虫,好家伙。
其实百度网盘的资源入口有两种方式:
一种是:http://pan.baidu.com/s/1qXQD2Pm,最后为短码。
另一种是:http://pan.baidu.com/share/link?uk=1813251526&shareid=540167442,关键是shareId+uk 前者已知道反爬虫,后者目前没有,所以用python测试后,本人又将代码翻译成了java,因为去转盘是用java写的,直接上代码:

注意代码本生要用来兼容360,微盘等网盘的,但有些网盘倒了,大家都知道,不过代码还是得在,这才是程序猿该有的思路,那就是可宽展,注意代码有个配置文件,我也附上吧:
360=class|contain|\u5206\u4EAB\u8005\u5DF2\u53D6\u6D88\u6B64\u5206\u4EAB
baidu=title|contain|\u94FE\u63A5\u4E0D\u5B58\u5728
weiyun=<h3>|contain|\u5206\u4EAB\u8D44\u6E90\u5DF2\u7ECF\u5220\u9664
leshi=title|ed|\u63D0\u53D6\u6587\u4EF6
sorry,unicode编码,麻烦你自己转下码吧,不会请百度:unicode转码工具
到此,白网盘网连接是否失效的验证,代码我已经完全公开,喜欢这篇博客的孩子请收藏并关注下。
