首先寫一個獲取HTTP的方法：

package wzgr;import java.io.BufferedReader; import java.io.InputStreamReader; import java.net.URL; import java.net.URLConnection; import java.util.List; import java.util.Map;public class HttpRequest {public static String sendGet(String url) {String result = "";BufferedReader in = null;try {String urlNameString = url;URL realUrl = new URL(urlNameString);// 打開和URL之間的連接URLConnection connection = realUrl.openConnection();// 設置通用的請求屬性connection.setRequestProperty("accept", "*/*");connection.setRequestProperty("connection", "Keep-Alive");connection.setRequestProperty("user-agent","Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");// 建立實際的連接connection.connect();// 獲取所有響應頭字段Map<String, List<String>> map = connection.getHeaderFields();// 遍歷所有的響應頭字段for (String key : map.keySet()) {System.out.println(key + "--->" + map.get(key));}// 定義 BufferedReader輸入流來讀取URL的響應in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));String line;while ((line = in.readLine()) != null) {result += line;}} catch (Exception e) {System.out.println("發送GET請求出現異常！" + e);e.printStackTrace();}// 使用finally塊來關閉輸入流finally {try {if (in != null) {in.close();}} catch (Exception e2) {e2.printStackTrace();}}return result;}}

然后寫一個主方法調用：

public static void main(String[] args) {String b=HttpRequest.sendGet("http://www.XXXX.com/......");System.out.println(b);}

?
