是否可以使用一些代码获得设备的IP地址?
当前回答
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);

如果你有一个壳;Ifconfig eth0也适用于x86设备
简单地使用凌空从这个网站获得ip
RequestQueue queue = Volley.newRequestQueue(this);
String urlip = "http://checkip.amazonaws.com/";
StringRequest stringRequest = new StringRequest(Request.Method.GET, urlip, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
txtIP.setText(response);
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
txtIP.setText("didnt work");
}
});
queue.add(stringRequest);
我使用以下代码: 我使用hashCode的原因是因为当我使用getHostAddress时,我得到了一些垃圾值附加到ip地址。但是hashCode对我来说工作得很好,这样我就可以使用Formatter来获得具有正确格式的ip地址。
下面是示例输出:
1.使用 getHostAddress : ***** IP=fe80::65ca:a13d:ea5a:233d%rmnet_sdio0
2.使用hashCode和Formatter: ***** IP=238.194.77.212
如你所见,第二种方法正好满足了我的需求。
public String getLocalIpAddress() {
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()) {
String ip = Formatter.formatIpAddress(inetAddress.hashCode());
Log.i(TAG, "***** IP="+ ip);
return ip;
}
}
}
} catch (SocketException ex) {
Log.e(TAG, 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Kotlin中,没有Formatter
private fun getIPAddress(useIPv4 : Boolean): String {
try {
var interfaces = Collections.list(NetworkInterface.getNetworkInterfaces())
for (intf in interfaces) {
var addrs = Collections.list(intf.getInetAddresses());
for (addr in addrs) {
if (!addr.isLoopbackAddress()) {
var sAddr = addr.getHostAddress();
var isIPv4: Boolean
isIPv4 = sAddr.indexOf(':')<0
if (useIPv4) {
if (isIPv4)
return sAddr;
} else {
if (!isIPv4) {
var delim = sAddr.indexOf('%') // drop ip6 zone suffix
if (delim < 0) {
return sAddr.toUpperCase()
}
else {
return sAddr.substring(0, delim).toUpperCase()
}
}
}
}
}
}
} catch (e: java.lang.Exception) { }
return ""
}
