java+python判断百度云的分享链接是否失效（提供思路，java转nj，也是分分钟）
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
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： https://pan.baidu.com/share/link?uk=1813251526&shareid=54016
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/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=<h3>|contain|u5206u4EABu8D44u6E90u5DF2u7ECFu5220u9664
leshi=title|ed|u63D0u53D6u6587u4EF6
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。
