我不知道現在有多少人在用網盤搜索引擎,但就去轉盤網來說本人傾注了很多的心血,現在使用的人數也還可以,網盤資源都有個通病,那就是資源可能失效,但很多引擎都沒有做失效判斷,尤其是一些google自定義的引擎,技術含量不高,站長也就花心思賺錢,很少考慮用戶體驗。這篇文章是本人又一篇技術公開博客,之前本人已經公開了去轉盤
網的幾乎所有的技術細節,這一篇繼續補充:
首先做個回顧:百度網盤爬蟲 java分詞算法 數據庫自動備份 代理服務器爬取 邀請好友注冊

response = urllib2.urlopen(req,None,8) #在這里應該加入代理
html = response.read()

#url="http://pan.baidu.com/share/link?uk=1813251526&shareid=540167442"
url="http://pan.baidu.com/s/1qXQD2Pm"
html=gethtml(url)
print html
結果:e HTTP Error 403: Forbidden,這就是說,度娘他是反爬蟲的,之后看了很多網站,一不小心試了下面的鏈接:
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
結果:
百度云 網盤-鏈接不存在 ,你懂的,有這個的必然已經失效,看來度娘沒有反爬蟲,好家伙。
其實百度網盤的資源入口有兩種方式:
一種是:http://pan.baidu.com/s/1qXQD2Pm,最后為短碼。
另一種是:http://pan.baidu.com/share/li...,關鍵是shareId+uk 前者已知道反爬蟲,后者目前沒有,所以用python測試后,本人又將代碼翻譯成了java,因為去轉盤是用java寫的,直接上代碼:

注意代碼本生要用來兼容360,微盤等網盤的,但有些網盤倒了,大家都知道,不過代碼還是得在,這才是程序猿該有的思路,那就是可寬展,注意代碼有個配置文件,我也附上吧:
360=class|contain|u5206u4EABu8005u5DF2u53D6u6D88u6B64u5206u4EAB baidu=title|contain|u94FEu63A5u4E0Du5B58u5728 weiyun=

sorry,unicode編碼,麻煩你自己轉下碼吧,不會請百度:unicode轉碼工具
到此,去轉盤網鏈接是否失效的驗證,代碼我已經完全公開,喜歡這篇博客的孩子請收藏并關注下。
