最近看了好多網(wǎng)上獲取IP地址的例子，發(fā)現(xiàn)好多都不完全準(zhǔn)確，這里我寫一下獲取ip地址的兩種方式。

比如微信支付，后臺在做接口的時候，要求App端傳入IP地址，我們需要判斷是網(wǎng)絡(luò)環(huán)境，WI-FI還是3G，所以需要獲取這兩種環(huán)境的ip地址。

第一步：首先是判斷網(wǎng)絡(luò)環(huán)境：

String ip;

ConnectivityManager conMann = (ConnectivityManager)

this.getSystemService(Context.CONNECTIVITY_SERVICE);

NetworkInfo mobileNetworkInfo = conMann.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

NetworkInfo wifiNetworkInfo = conMann.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

if (mobileNetworkInfo.isConnected()) {

ip = getLocalIpAddress();

System.out.println('本地ip-----'+ip);

}else if(wifiNetworkInfo.isConnected())

{

WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);

WifiInfo wifiInfo = wifiManager.getConnectionInfo();

int ipAddress = wifiInfo.getIpAddress();

ip = intToIp(ipAddress);

System.out.println('wifi_ip地址為------'+ip);

}

如果連接的是移動網(wǎng)絡(luò)，第二步，獲取本地ip地址：getLocalIpAddress();這樣獲取的是ipv4格式的ip地址。

public String getLocalIpAddress() {

try {

String ipv4;

ArrayList nilist = Collections.list(NetworkInterface.getNetworkInterfaces());

for (NetworkInterface ni: nilist)

{

ArrayList ialist = Collections.list(ni.getInetAddresses());

for (InetAddress address: ialist){

if (!address.isLoopbackAddress() && InetAddressUtils.isIPv4Address(ipv4=address.getHostAddress()))

{

return ipv4;

}

}

}

} catch (SocketException ex) {

Log.e('localip', ex.toString());

}

return null;

}

如果連接的是WI-FI網(wǎng)絡(luò)，第三步，獲取WI-FI ip地址：intToIp(ipAddress);

public static String intToIp(int ipInt) {

StringBuilder sb = new StringBuilder();

sb.append(ipInt & 0xFF).append('.');

sb.append((ipInt >> 8) & 0xFF).append('.');

sb.append((ipInt >> 16) & 0xFF).append('.');

sb.append((ipInt >> 24) & 0xFF);

return sb.toString();

}

網(wǎng)上的很多代碼獲取的是ipv6的本地ip，在微信支付里這種ip地址無法調(diào)起微信支付，附代碼：

private String getlocalIp() {

String ip;

try {

for (Enumeration en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {

NetworkInterface intf = en.nextElement();

for (Enumeration enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {

InetAddress inetAddress = enumIpAddr.nextElement();

if (!inetAddress.isLoopbackAddress()&&!inetAddress.isLinkLocalAddress()) {

// ip=inetAddress.getHostAddress().toString();

System.out.println('ip=========='+inetAddress.getHostAddress().toString());

return inetAddress.getHostAddress().toString();

}

}

}

} catch (SocketException ex) {

Log.e('WifiPreference IpAddress', ex.toString());

}

return null;

}
