如何从Android本地VPN提取所有网络URL

如何解决如何从Android本地VPN提取所有网络URL

我正在创建运行良好的本地VPN。但是我想获取用户在浏览器中单击的所有网站URL。我也想从数据包中捕获目标地址。

我尝试了互联网上所有可用的方法，但没有找到任何解决方案。

class LocalVpnService : VpnService(){
    private enum class Command {
        Start
    }

    companion object {
        private const val TAG = "LocalVpnService"
        private const val EXTRA_COMMAND = "Command"

        @JvmStatic
        fun start(context: Context) {
            val intent = Intent(context,LocalVpnService::class.java)
            intent.putExtra(EXTRA_COMMAND,Command.Start)
            context.startService(intent)
        }
    }

    private val closeCh = Channel<Unit>()
    private val inputCh = Channel<IpV4Packet>()

    private var vpnInterface: ParcelFileDescriptor? = null
    
    private var packet : IpV4Packet ?= null
    private var packetV6 : IpV6ExtDestinationOptionsPacket ?= null

    override fun onStartCommand(intent: Intent?,flags: Int,startId: Int): Int {
        println("QAS onStartCommand: ${intent?.getStringExtra("COMMAND")}")
        if (intent?.getStringExtra("COMMAND") == "STOP") {
            println("QAS vpn: $vpnInterface")
            if(vpnInterface != null){
                println("QAS Stop Vpn block")
                stopVpn(vpnInterface!!)
            }else{
                Log.i(TAG,"QAS VPN is not running")
            }
        }else if(intent?.getStringExtra("COMMAND") == "START"){
            Log.i(TAG,"QAS VPN start else if: $vpnInterface")
            if(vpnInterface == null){
                Log.i(TAG,"QAS VPN is started.")
                vpnStart()
            }else{
                Log.i(TAG,"QAS VPN is already running.")
            }
        }
        return Service.START_STICKY
    }

    override fun onCreate() {
        super.onCreate()
      
    }

    override fun onDestroy() {
        super.onDestroy()
        stopSelf()
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    private fun vpnStart(){
        // Check if Wi-Fi
        val wifi = Util.isWifiActive(this)
        Log.i(TAG,"QAS wifi=$wifi")

        // Build VPN service
        val builder = Builder()
        builder.setSession(getString(R.string.app_name))
        builder.addAddress("10.1.10.1",24)
        builder.addRoute("0.0.0.0",0)

        // Add list of allowed applications
        for (rule in Rule.getRules(this)) if (!(if (wifi) rule.wifi_blocked else rule.other_blocked)) {
            Log.i(TAG,"Allowing " + rule.info.packageName)
            try {
                builder.addDisallowedApplication(rule.info.packageName)
            } catch (e: java.lang.Exception) {
                Log.e(TAG,"QAS Exception: $e")
            }
        }

        // Build configure intent
        val configure = Intent(this,MainActivity::class.java)
        val pi = PendingIntent.getActivity(this,configure,PendingIntent.FLAG_UPDATE_CURRENT)
        builder.setConfigureIntent(pi)

        vpnInterface = builder.establish()

    }
