愛華網(wǎng)而更換IP的方式,當(dāng)然也要做成自動(dòng)的,不可能讓用戶再手動(dòng)更新,那就達(dá)不到"自動(dòng)化"了.
在win中,動(dòng)態(tài)更改IP有不少方法,有的直接調(diào)用winapi(類Win32_NetworkAdapterConfiguration官方文檔:http://msdn.microsoft.com/zh-cn/library/aa394217(v=vs.85).aspx),不管是C++或是C#甚至是vbs腳本.也可以通過(guò)在cmd下執(zhí)行netsh命令來(lái)修改(可以寫成bat,供程序從外部調(diào)用).
通過(guò)在程序中調(diào)用WINAPI,可以方便獲得返回的狀態(tài),編制更健壯的程序.
對(duì)于躲避監(jiān)控,最好的辦法是執(zhí)行分布式批量下載.當(dāng)然,最安全的做法是,在幾十個(gè)學(xué)校中執(zhí)行.數(shù)據(jù)庫(kù)商家及學(xué)校,都無(wú)法防得了.大多知名的迅速"暴富"的商業(yè)公司就是利用這種方法來(lái)積累資源的.只是可惜,學(xué)校里頭的防控只防學(xué)生,卻不防大蟲.真所謂"竊鉤者誅，竊國(guó)者為諸侯".有人指責(zé)我非法采集超星的視頻,可這些道貌岸然的人物,為何不指責(zé)超星掏掉CNKI?不才只是為了方便窮書生找資源的苦楚,面對(duì)商業(yè)公司,而對(duì)國(guó)家科研機(jī)構(gòu)的重重壁壘,讓些小蟲有點(diǎn)活路不壞壟斷大局.知識(shí)越來(lái)越容易共享,也越來(lái)越不會(huì)分享.不管是商還是官,還是官商勾結(jié),窮書生從不是他們的服務(wù)對(duì)象.我沒有用上百臺(tái)機(jī)器分布采集,也沒有直接掛機(jī)到鏡像下載,我只是想從那個(gè)高墻處挖個(gè)小水溝,供窮書生們啜食.我只提供了省掉個(gè)人點(diǎn)擊之苦的CNKI批量下載器,而且也做了數(shù)量的限制,別的下載器都限內(nèi)部使用,沒有在互聯(lián)網(wǎng)上散播,希望那些高尚的大人物,莫太指責(zé)我惡意踐踏知識(shí)產(chǎn)權(quán),不尊重作者的研究成果.我只是一只小蟲,挖個(gè)小洞,給窮書生們解解渴,因?yàn)楦F書生們不能公款吃喝,大魚大肉.
