<span style="font-size:18px;">// 擷取外網IPpublic static String GetNetIp() {URL infoUrl = null;InputStream inStream = null;try {// http://iframe.ip138.com/ic.asp// infoUrl = new URL("http://city.ip138.com/city0.asp");infoUrl = new URL("http://ip38.com");URLConnection connection = infoUrl.openConnection();HttpURLConnection httpConnection = (HttpURLConnection) connection;int responseCode = httpConnection.getResponseCode();if (responseCode == HttpURLConnection.HTTP_OK) {inStream = httpConnection.getInputStream();BufferedReader reader = new BufferedReader(new InputStreamReader(inStream, "utf-8"));StringBuilder strber = new StringBuilder();String line = null;while ((line = reader.readLine()) != null)strber.append(line + "\n");inStream.close();// 從反饋的結果中提取出IP地址// int start = strber.indexOf("[");// Log.d("zph", "" + start);// int end = strber.indexOf("]", start + 1);// Log.d("zph", "" + end);line = strber.substring(378, 395);line.replaceAll(" ", "");return line;}} catch (MalformedURLException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}return null;}</span>

另有一個擷取外網IP的高端方法

public static String GetNetIp(){String IP = "";try{String address = "http://ip.taobao.com/service/getIpInfo2.php?ip=myip";URL url = new URL(address);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setUseCaches(false);if (connection.getResponseCode() == HttpURLConnection.HTTP_OK){InputStream in = connection.getInputStream();// 將流轉化為字串BufferedReader reader = new BufferedReader(new InputStreamReader(in));String tmpString = "";StringBuilder retJSON = new StringBuilder();while ((tmpString = reader.readLine()) != null){retJSON.append(tmpString + "\n");}JSONObject jsonObject = new JSONObject(retJSON.toString());String code = jsonObject.getString("code");if (code.equals("0")){JSONObject data = jsonObject.getJSONObject("data");IP = data.getString("ip") + "(" + data.getString("country")+ data.getString("area") + "區"+ data.getString("region") + data.getString("city")+ data.getString("isp") + ")";Log.e("提示", "您的IP地址是：" + IP);}else{IP = "";Log.e("提示", "IP介面異常，無法擷取IP地址！");}}else{IP = "";Log.e("提示", "網路連接異常，無法擷取IP地址！");}}catch (Exception e){IP = "";Log.e("提示", "擷取IP地址時出現異常，異常資訊是：" + e.toString());}return IP;}
