爬蟲訪問中，如何解決網站限制IP的問題？?? ?
?

開發了一個爬蟲，布置在自己的服務器上，請求某網站的查詢功能，然后抓取查詢結果，結果訪問才一會兒，就被提示封IP了。有什么好的解決方法嗎？?

1. 某寶買代理，簡單，但是太貴；

2. ADSL動態獲取ip。

java代碼：

package?com.sesame.network;??

??

import?java.io.BufferedReader;??

import?java.io.InputStreamReader;??

??

public?class?ConnectNetWork?{??

??

????/**?

?????*?執行CMD命令,并返回String字符串?

?????*/??

????public?static?String?executeCmd(String?strCmd)?throws?Exception?{??

????????Process?p?=?Runtime.getRuntime().exec("cmd?/c?"?+?strCmd);??

????????StringBuilder?sbCmd?=?new?StringBuilder();??

????????BufferedReader?br?=?new?BufferedReader(new?InputStreamReader(p??

????????????????.getInputStream()));??

????????String?line;??

????????while?((line?=?br.readLine())?!=?null)?{??

????????????sbCmd.append(line?+?"\n");??

????????}??

????????return?sbCmd.toString();??

????}??

??

????/**?

?????*?連接ADSL?

?????*/??

????public?static?boolean?connAdsl(String?adslTitle,?String?adslName,?String?adslPass)?throws?Exception?{??

????????System.out.println("正在建立連接.");??

????????String?adslCmd?=?"rasdial?"?+?adslTitle?+?"?"?+?adslName?+?"?"??

????????????????+?adslPass;??

????????String?tempCmd?=?executeCmd(adslCmd);??

????????//?判斷是否連接成功??

????????if?(tempCmd.indexOf("已連接")?>?0)?{??

????????????System.out.println("已成功建立連接.");??

????????????return?true;??

????????}?else?{??

????????????System.err.println(tempCmd);??

????????????System.err.println("建立連接失敗");??

????????????return?false;??

????????}??

????}??

??

????/**?

?????*?斷開ADSL?

?????*/??

????public?static?boolean?cutAdsl(String?adslTitle)?throws?Exception?{??

????????String?cutAdsl?=?"rasdial?"?+?adslTitle?+?"?/disconnect";??

????????String?result?=?executeCmd(cutAdsl);??

?????????

????????if?(result.indexOf("沒有連接")!=-1){??

????????????System.err.println(adslTitle?+?"連接不存在!");??

????????????return?false;??

????????}?else?{??

????????????System.out.println("連接已斷開");??

????????????return?true;??

????????}??

????}??

?????

????public?static?void?main(String[]?args)?throws?Exception?{??

????????connAdsl("寬帶","hzhz**********","******");??

????????Thread.sleep(1000);??

????????cutAdsl("寬帶");??

????????Thread.sleep(1000);??

????????//再連，分配一個新的IP??

????????connAdsl("寬帶","hzhz**********","******");??

????}??

}??
