使用Java抓取网页内容

import java.net.*;
import java.io.*;


public class CheckURL {
     
     /**
     *
     * @param urlvalue
     *
     * @return 获取url内容
     */
  public static String check(String urlvalue ) {
	 
	 
	  String inputLine="";
	  String line2 = "";
	  
		try{
				URL url = new URL(urlvalue);
				
				HttpURLConnection urlConnection  = (HttpURLConnection)url.openConnection();
				
				BufferedReader in  = new BufferedReader(
			            new InputStreamReader(
			            		urlConnection.getInputStream()));
				while ((line2 = in.readLine()) != null) { 
				inputLine+=line2;
				}
		}
				catch(Exception e){
					e.printStackTrace();
				}
			//System.out.println(inputLine);  系统打印出抓取得验证结果
			
	    return inputLine;
  }

  public static void main(String a[]){
	System.out.println(CheckURL.check(a[0]));
  }


  }
