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。这篇文章是本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

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

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/li...
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:
百度云 网盘-链接不存在 ,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/li...,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|u5206u4EABu8005u5DF2u53D6u6D88u6B64u5206u4EAB baidu=title|contain|u94FEu63A5u4E0Du5B58u5728 weiyun=

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,去转盘网链接是否失效的验证,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。
