获取wifi无线网的ip

function getWifiIp() {
    const MainActivity = plus.android.runtimeMainActivity()
    const Context = plus.android.importClass('android.content.Context')
    plus.android.importClass('android.net.wifi.WifiManager')
    plus.android.importClass('android.net.wifi.WifiInfo')
    plus.android.importClass('android.net.wifi.ScanResult')
    plus.android.importClass('java.util.ArrayList')
    const wifiManager = MainActivity.getSystemService(Context.WIFI_SERVICE)
    const wifiInfo = wifiManager.getConnectionInfo()
    const ipAddress = wifiInfo.getIpAddress()
    const wifiIp = ((ipAddress & 0xff) + '.' + (ipAddress>>8 & 0xff) + '.' + (ipAddress>>16 & 0xff) + '.' + (ipAddress>>24 & 0xff))
    return wifiIp
}

获取有线网的ip

function getLanIp() {
    const MainActivity = plus.android.runtimeMainActivity()
    const Context = plus.android.importClass('android.content.Context')
    plus.android.importClass('android.net.ConnectivityManager')
    const lanManager = MainActivity.getSystemService(Context.CONNECTIVITY_SERVICE)
    const lanInfo = lanManager.getLinkProperties(lanManager.getActiveNetwork())
    const lanIpAddress = plus.android.invoke(lanInfo, 'getLinkAddresses')
    const lanIpAddressStr = lanIpAddress.toString()
    const lanIpaddressArr = lanIpAddressStr.split(',')
    const lanIp = lanIpaddressArr[1].split('/')[0]
    return lanIp
}
