我不知道現在有多少人在用網盤搜尋引擎,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,很少考慮使用者體驗。這篇文章是本人又一篇技術公開部落格,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分詞演算法 資料庫自動備份 代理伺服器爬取 邀請好友註冊

from __future__ import division  # 精確除法

from _sqlite3 import SQLITE_ALTER_TABLE

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) #在這裡應該加入代理
        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

結果:e HTTP Error 403: Forbidden,這就是說,度娘他是反爬蟲的,之後看了很多網站,一不小心試了下面的連結:

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:<title>百度雲 網盤-連結不存在</title>,你懂的,有這個的必然已經失效,看來度娘沒有反爬蟲,好傢伙。

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,最後為短碼。

另一種是:http://pan.baidu.com/share/li…,關鍵是shareId uk 前者已知道反爬蟲,後者目前沒有,所以用python測試後,本人又將程式碼翻譯成了java,因為去轉盤是用java寫的,直接上程式碼:

注意程式碼本生要用來相容360,微盤等網盤的,但有些網盤倒了,大家都知道,不過程式碼還是得在,這才是程式猿該有的思路,那就是可寬展,注意程式碼有個配置檔案,我也附上吧:

360=class|contain|u5206u4EABu8005u5DF2u53D6u6D88u6B64u5206u4EAB
baidu=title|contain|u94FEu63A5u4E0Du5B58u5728
weiyun=<h3>|contain|u5206u4EABu8D44u6E90u5DF2u7ECFu5220u9664
leshi=title|ed|u63D0u53D6u6587u4EF6

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,去轉盤網連結是否失效的驗證,程式碼我已經完全公開,喜歡這篇部落格的孩子請收藏並關注下。
