以下是 Unity 在 Android 平台和 iOS 平台下实现长连接访问的示例代码:
```csharp
using UnityEngine;
using System.Collections;
using System.Net.Sockets;
using System.Threading;
public class TcpExample : MonoBehaviour
{
private TcpClient client;
private NetworkStream stream;
private Thread receiveThread;
private bool isRunning = false;
void Start()
{
// 连接服务器
client = new TcpClient("192.168.1.100", 8888);
stream = client.GetStream();
// 启动接收线程
isRunning = true;
receiveThread = new Thread(new ThreadStart(ReceiveMessage));
receiveThread.Start();
}
void OnDestroy()
{
// 关闭连接
isRunning = false;
if (receiveThread != null)
{
receiveThread.Join();
}
if (client != null)
{
client.Close();
}
}
void SendMessage(string message)
{
// 发送消息
byte[] data = System.Text.Encoding.UTF8.GetBytes(message);
stream.Write(data, 0, data.Length);
}
void ReceiveMessage()
{
// 接收消息
while (isRunning)
{
if (stream.DataAvailable)
{
byte[] buffer = new byte[1024];
int length = stream.Read(buffer, 0, buffer.Length);
string message = System.Text.Encoding.UTF8.GetString(buffer, 0, length);
Debug.Log(message);
}
else
{
Thread.Sleep(100);
}
}
}
}
```
上面的代码演示了如何在 Unity 中实现 TCP 长连接访问,包括连接服务器、发送消息和接收消息。需要注意的是,在 Android 平台和 iOS 平台下,需要在 AndroidManifest.xml 和 Info.plist 文件中添加网络访问权限。同时,在 iOS 平台下,需要在 Info.plist 文件中添加 ATS(App Transport Security)例外,以允许非 HTTPS 的网络连接。
