爱华网而更换IP的方式,当然也要做成自动的,不可能让用户再手动更新,那就达不到"自动化"了.
在win中,动态更改IP有不少方法,有的直接调用winapi(类Win32_NetworkAdapterConfiguration官方文档:http://msdn.microsoft.com/zh-cn/library/aa394217(v=vs.85).aspx),不管是C++或是C#甚至是vbs脚本.也可以通过在cmd下执行netsh命令来修改(可以写成bat,供程序从外部调用).
通过在程序中调用WINAPI,可以方便获得返回的状态,编制更健壮的程序.
对于躲避监控,最好的办法是执行分布式批量下载.当然,最安全的做法是,在几十个学校中执行.数据库商家及学校,都无法防得了.大多知名的迅速"暴富"的商业公司就是利用这种方法来积累资源的.只是可惜,学校里头的防控只防学生,却不防大虫.真所谓"窃钩者诛，窃国者为诸侯".有人指责我非法采集超星的视频,可这些道貌岸然的人物,为何不指责超星掏掉CNKI?不才只是为了方便穷书生找资源的苦楚,面对商业公司,而对国家科研机构的重重壁垒,让些小虫有点活路不坏垄断大局.知识越来越容易共享,也越来越不会分享.不管是商还是官,还是官商勾结,穷书生从不是他们的服务对象.我没有用上百台机器分布采集,也没有直接挂机到镜像下载,我只是想从那个高墙处挖个小水沟,供穷书生们啜食.我只提供了省掉个人点击之苦的CNKI批量下载器,而且也做了数量的限制,别的下载器都限内部使用,没有在互联网上散播,希望那些高尚的大人物,莫太指责我恶意践踏知识产权,不尊重作者的研究成果.我只是一只小虫,挖个小洞,给穷书生们解解渴,因为穷书生们不能公款吃喝,大鱼大肉.
