Java如何实现简单的whois查询

  利用Java socket 实现根据IP地址查询该IP相关的注册信息。

  源代码直接下载:java_whois.zip

  相关的两个类WhoisBean.java 和WhoisQuery.java 代码实现如下:

  Java代码

  import java.util.LinkedHashMap;

  import java.util.List;

  import java.util.Map;

  import java.util.Map.Entry;

  /**

  *

  * @author Michael sun

  */

  public class WhoisQuery {

  /**

  *

  * @param ip

  */

  private void queryIpInfo(String ip) {

  Map map = new LinkedHashMap();

  try {

  WhoisBean bean = new WhoisBean();

  bean.setTimeout(0);

  // bean.setServer("whois.apnic.net");

  bean.setServer("whois.ripe.net");

  bean.queryInfoByIp(ip);

  List infoList = bean.getInfoList();

  String value = "";

  String key = "";

  for (String infoTmp : infoList) {

  String[] arr = infoTmp.split(":[ ]*");

  if (arr.length > 1) {

  key = arr[0];

  value = arr[1];

  } else {

  value = arr[0].trim();

  }

  if (null == map.get(key)) {

  map.put(key, "");

  }

  value = map.get(key) + value;

  map.put(key, value);

  }

  } catch (Exception e) {

  e.printStackTrace();

  }

  for (Entry entry : map.entrySet()) {

  System.out.println(entry.getKey() + ":" + entry.getValue());

  }

  }

  /**

  * @param args

  */

  public static void main(String[] args) {

  String ip = "129.42.58.216";// "163.1.13.189";

  WhoisQuery query = new WhoisQuery();

  query.queryIpInfo(ip);

  }

  }

  Java代码

  import java.io.BufferedReader;

  import java.io.InputStreamReader;

  import java.io.PrintStream;

  import java.net.Socket;

  import java.util.ArrayList;

  import java.util.List;

  /**

  * WhoisBean

  * @author Michael sun

  */

  public class WhoisBean {

  /**

  * server address

  */

  private String server = "";

  /**

  * port

  */

  private int port = 43;

  /**

  * timeout/minute

  */

  private int timeout = 0;

  /**

  * infoList

  */

  private List infoList = new ArrayList();

  /**

  * @param ip

  * @throws Exception

  */

  @SuppressWarnings("unchecked")

  public void queryInfoByIp(String ip) throws Exception {

  Socket theSocket = null;

  BufferedReader br = null;

  PrintStream ps = null;

  int qryCount = 0;

  while (qryCount < 5) {

  qryCount++;

  try {

  theSocket = new Socket(server, port);

  theSocket.setSoTimeout(timeout * 1000);

  ps = new PrintStream(theSocket.getOutputStream());

  ps.println(ip);

  br = new BufferedReader(new InputStreamReader(theSocket

  .getInputStream()));

  infoList.add("ip:" + ip);

  String readLine = "";

  int i = 0;

  System.out.println("Whois query read start.... ");

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

  System.out.println("***" + readLine);

  if (readLine.length() > 0 && readLine.charAt(0) != '%') {

  infoList.add(readLine);

  i++;

  // 默认读取100行数据

  if (i > 100 || readLine.startsWith("source")) {

  break;

  }

  }

  }

  System.out.println("querylist size:" + infoList.size());

  break;

  } catch (Exception e) {

  System.out.println("EXCEPTION : " + e);

  } finally {

  if (null != br) {

  br.close();

  }

  if (null != ps) {

  ps.close();

  }

  if (null != theSocket) {

  theSocket.close();

  }

  }

  }

  }

  /**

  * @return the server

  */

  public String getServer() {

  return server;

  }

  /**

  * @return the port

  */

  public int getPort() {

  return port;

  }

  /**

  * @return the timeout

  */

  public int getTimeout() {

  return timeout;

  }

  /**

  * @param pServer the server to set

  */

  public void setServer(String pServer) {

  server = pServer;

  }

  /**

  * @param pPort the port to set

  */

  public void setPort(int pPort) {

  port = pPort;

  }

  /**

  * @param pTimeout the timeout to set

  */

  public void setTimeout(int pTimeout) {

  timeout = pTimeout;

  }

  /**

  * @return the infoList

  */

  public List getInfoList() {

  return infoList;

  }

  /**

  * @param pInfoList the infoList to set

  */

  public void setInfoList(List pInfoList) {

  infoList = pInfoList;

  }

  }

  运行WhoisQuery这个类就可以看到如下信息:

  Java代码

  Whois query read start....
