利用淘宝获取手机的IP地址，同样的原理，也可以利用其它网站的服务器获取手机的公网真实IP地址。
public static String getPhoneIP()
{
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();
// 将流转化为字符串
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") + "区"
// + data.getString("region") + data.getString("city")
// + data.getString("isp") + ")";
IP = data.getString("ip");
Log.e("提示", "您的IP地址是：" + IP);
}
else
{
IP = "";
Log.e("提示", "IP接口异常，无法获取IP地址！");
}
}
else
{
IP = "";
Log.e("提示", "网络连接异常，无法获取IP地址！");
}
}
catch (Exception e)
{
IP = "";
Log.e("提示", "获取IP地址时出现异常，异常信息是：" + e.toString());
}
return IP;
}
