嗨我想从网上获取代理列表并搜索它以查找工作代理号码和端口。我的问题是,当我抓住网站如何通过它搜索它只识别ips和poorts并disragrd其余的?到目前为止,我所做的一切都是工作 我如何识别代理号码,没有别的?对不起,任何帮助将不胜感激,但我是一个新人:)
package proxytester;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
public class ProxyTester{
public static void main(String[] args) {
try{
URL grab = new URL("http://www.example.com");
BufferedReader in = new BufferedReader(
new InputStreamReader(grab.openStream()));
String input;
while ((input = in.readLine()) != null) {
if(input.charAt(0)=='n'){// the site starts its proxy list with name but this line throws an error
System.out.println(input);
}else if(input.charAt(0)== ' '){
System.out.println("empty");
}else
continue;
}
in.close();
}catch(MalformedURLException aa){
System.out.println("site error");
}catch (IOException e) {
System.out.println("io error");
}
}//end main
}//end main

我建议使用正则表达式来查找IP地址和端口。这是一个需要的正则表达式:java regex matching ip address and port number as captured groups 本文介绍如何在java中使用正则表达式:http://www.mkyong.com/regular-expressions/how-to-validate-ip-address-with-regular-expression/
