最近接入了一个新的SDK,初始化接口需求传入当前设备的IP和UA作为参数。本文介绍如何获取设备的IP和UA。
获取IP
运用WIFI联网与不运用WIFI,获取到的IP地址不同。因此,需求先判别当前设备经过哪种方式联网,然后再获取对应的IP地址。
- 判别网络连接类型
经过ConnectivityManager
判别网络连接类型,代码如下:
private fun checkCurrentNetworkType() {
val connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
connectivityManager.run {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
when (activeNetworkInfo?.type) {
ConnectivityManager.TYPE_MOBILE -> {
// 经过手机流量
}
ConnectivityManager.TYPE_WIFI -> {
// 经过WIFI
}
else -> {}
}
} else {
// Android M 以上主张运用getNetworkCapabilities API
activeNetwork?.let { network ->
getNetworkCapabilities(network)?.let { networkCapabilities ->
if (networkCapabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_VALIDATED)) {
when {
networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_CELLULAR) -> {
// 经过手机流量
}
networkCapabilities.hasTransport(NetworkCapabilities.TRANSPORT_WIFI) -> {
// 经过WIFI
}
}
}
}
}
}
}
}
- 获取手机卡联网 IP
经过NetworkInterface
获取IPV4地址,代码如下:
NetworkInterface.getNetworkInterfaces().let {
loo@ for (networkInterface in Collections.list(it)) {
for (inetAddresses in Collections.list(networkInterface.inetAddresses)) {
if (!inetAddresses.isLoopbackAddress && !inetAddresses.isLinkLocalAddress) {
// IP地址
val mobileIp = inetAddresses.hostAddress
break@loo
}
}
}
}
- 获取WIFI联网 IP
经过ConnectivityManager
或WifiManager
来获取IP地址,代码如下:
private fun getWIFIIp() {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.Q) {
val wifiManager = applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager
// IP 地址
val wifiIp = Formatter.formatIpAddress(wifiManager.connectionInfo.ipAddress)
} else {
// Android Q 以上主张运用getNetworkCapabilities API
val connectivityManager = getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager
connectivityManager.run {
activeNetwork?.let { network ->
(getNetworkCapabilities(network)?.transportInfo as? WifiInfo)?.let { wifiInfo ->
// IP 地址
val wifiIp = Formatter.formatIpAddress(wifiInfo.ipAddress)
}
}
}
}
}
获取UA
获取设备的UserAgent比较简单,代码如下:
// 体系 UA
System.getProperty("http.agent")
// WebView UA
WebSettings.getDefaultUserAgent(context)
