是否可以使用一些代码获得设备的IP地址?
当前回答
kotlin语言。
fun contextIP(context: Context): String {
val wm: WifiManager = context.getSystemService(Context.WIFI_SERVICE) as WifiManager
return Formatter.formatIpAddress(wm.connectionInfo.ipAddress)
}
其他回答
// @NonNull
public static String getIPAddress() {
if (TextUtils.isEmpty(deviceIpAddress))
new PublicIPAddress().execute();
return deviceIpAddress;
}
public static String deviceIpAddress = "";
public static class PublicIPAddress extends AsyncTask<String, Void, String> {
InetAddress localhost = null;
protected String doInBackground(String... urls) {
try {
localhost = InetAddress.getLocalHost();
URL url_name = new URL("http://bot.whatismyipaddress.com");
BufferedReader sc = new BufferedReader(new InputStreamReader(url_name.openStream()));
deviceIpAddress = sc.readLine().trim();
} catch (Exception e) {
deviceIpAddress = "";
}
return deviceIpAddress;
}
protected void onPostExecute(String string) {
Lg.d("deviceIpAddress", string);
}
}
请检查这个代码…使用此代码。我们将从移动互联网获得IP…
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements(); ) {
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements(); ) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
return inetAddress.getHostAddress().toString();
}
}
}
private InetAddress getLocalAddress()throws IOException {
try {
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
NetworkInterface intf = en.nextElement();
for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
InetAddress inetAddress = enumIpAddr.nextElement();
if (!inetAddress.isLoopbackAddress()) {
//return inetAddress.getHostAddress().toString();
return inetAddress;
}
}
}
} catch (SocketException ex) {
Log.e("SALMAN", ex.toString());
}
return null;
}
你可以这样做
String stringUrl = "https://ipinfo.io/ip";
//String stringUrl = "http://whatismyip.akamai.com/";
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(MainActivity.instance);
//String url ="http://www.google.com";
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, stringUrl,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
Log.e(MGLogTag, "GET IP : " + response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
IP = "That didn't work!";
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
在你的活动中,下面的函数getIpAddress(context)返回电话的IP地址:
public static String getIpAddress(Context context) {
WifiManager wifiManager = (WifiManager) context.getApplicationContext()
.getSystemService(WIFI_SERVICE);
String ipAddress = intToInetAddress(wifiManager.getDhcpInfo().ipAddress).toString();
ipAddress = ipAddress.substring(1);
return ipAddress;
}
public static InetAddress intToInetAddress(int hostAddress) {
byte[] addressBytes = { (byte)(0xff & hostAddress),
(byte)(0xff & (hostAddress >> 8)),
(byte)(0xff & (hostAddress >> 16)),
(byte)(0xff & (hostAddress >> 24)) };
try {
return InetAddress.getByAddress(addressBytes);
} catch (UnknownHostException e) {
throw new AssertionError();
}
}
