獲取本機外網ip地址

public static String getIP() {String ip = "http://pv.sohu.com/cityjson?ie=utf-8";String inputLine = "";String read = "";String toIp="";try {URL url = new URL(ip);HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));while ((read = in.readLine()) != null) {inputLine += read;}String ObjJson=inputLine.substring(inputLine.indexOf("=")+1,inputLine.length()-1); // System.out.println(ObjJson);JSONObject jsonObj= JSON.parseObject(ObjJson);toIp=jsonObj.getString("cip"); // throw new Exception();} catch (Exception e) {toIp="";}return toIp;}

獲取服務器IP地址

/*** 根據域名獲取ip地址*/public static String getIfIP() {String toIp="";try{String pathName="baidu.com";//這里沒有進行支持https協議的，可以自行進行切割字符串InetAddress address =InetAddress.getAllByName(pathName)[0];toIp=address.getHostAddress();}catch (Exception e){toIp="";}return toIp;}
