Question

我正在尝试在Android智能手机上接收Unity和C＃中设备的标准网关，但我无法修复它。

这就是为什么我问是否有可能使用Unity和C＃在Android智能手机上找到网关。

我已经尝试过这个，它在Unity编辑器中有效：

    NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        GatewayIPAddressInformationCollection addresses = adapterProperties.GatewayAddresses;
        if (addresses.Count > 0)
        {
            foreach (GatewayIPAddressInformation address in addresses)
            {
                if (address.Address.ToString() != "0.0.0.0")
                {
                    Debug.Log("Gateway: " + address.Address.ToString());
                }
            }
        }
    }

在 Network.java 目录中创建一个 Assets/Plugins/Android 文件。

        Enumeration<NetworkInterface> networkInterfaces = null;
        try {
            networkInterfaces = NetworkInterface.getNetworkInterfaces();

        }
        InetAddress address;
        while (networkInterfaces.hasMoreElements()) {
            NetworkInterface networkInterface = networkInterfaces.nextElement();
            Enumeration<InetAddress> inetAddresses = networkInterface.getInetAddresses();
            while (inetAddresses.hasMoreElements()) {
                address = inetAddresses.nextElement();
                String hostAddress = address.getHostAddress();
                Matcher matcher = ip.matcher(hostAddress);
                if (matcher.matches()) {
                    hostIp = hostAddress;
                    return hostIp;
                }
 
            }
        }
        return null;
    }

在 C# 代码中使用此脚本，如下所示：

using UnityEngine;
using UnityEngine.UI;

public class MyIPScript: MonoBehaviour
{

    public Text ipText;

    public void Start()
    {
        string ip = GetIP();
        ipText.text = ip;
    }

    private string GetIP() {
        AndroidJavaObject jo = new AndroidJavaObject("com.mynet.Network");
        AndroidJavaClass act = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
        return jo.Call<string>("getHostIp");
    }
}

注意：这仅适用于 Android 设备。如果您在 PC 上测试，您将看不到任何 IP 地址。因此，通过从 Android 中选择 Build Settings 并生成 apk 文件来构建您的统一项目，然后将其安装在您的 Android Phone 或 VR Headset 上。我在 Oculus Quest 上对其进行了测试，效果很好。
