unity基于插件BestHttp实现WebSocket链接

BestHTTP是Unity中一个用于HTTP和WebSocket通信的第三方网络插件，它提供了一些易于使用的API，可以帮助开发者快速地实现WebSocket通信。下面是基于BestHTTP实现WebSocket连接的示例代码：

using BestHTTP.WebSocket;
using UnityEngine;

public class WebSocketExample : MonoBehaviour
{
    private WebSocket webSocket;

    // Start is called before the first frame update
    void Start()
    {
        // 创建WebSocket实例
        webSocket = new WebSocket(new Uri("ws://your-websocket-server-url"));
        
        // 设置WebSocket事件回调函数
        webSocket.OnOpen += OnWebSocketOpen;
        webSocket.OnMessage += OnWebSocketMessageReceived;
        webSocket.OnError += OnWebSocketError;
        webSocket.OnClosed += OnWebSocketClosed;
        
        // 连接WebSocket服务器
        webSocket.Open();
    }

    // WebSocket连接成功
    private void OnWebSocketOpen(WebSocket webSocket)
    {
        Debug.Log("WebSocket connected.");
    }

    // WebSocket接收到消息
    private void OnWebSocketMessageReceived(WebSocket webSocket, string message)
    {
        Debug.Log("Received message: " + message);
    }

    // WebSocket连接错误
    private void OnWebSocketError(WebSocket webSocket, Exception exception)
    {
        Debug.LogError("WebSocket error: " + exception.Message);
    }

    // WebSocket连接关闭
    private void OnWebSocketClosed(WebSocket webSocket, UInt16 code, string message)
    {
        Debug.Log("WebSocket closed: " + message);
    }

    // 发送消息到WebSocket服务器
    void SendMessageToWebSocketServer(string message)
    {
        if (webSocket != null && webSocket.IsOpen)
        {
            webSocket.Send(message);
        }
        else
        {
            Debug.LogError("WebSocket is not connected.");
        }
    }

    // 关闭WebSocket连接
    void CloseWebSocketConnection()
    {
        if (webSocket != null)
        {
            webSocket.Close();
        }
    }

    // 在应用程序退出时关闭WebSocket连接
    private void OnApplicationQuit()
    {
        CloseWebSocketConnection();
    }
}

以上是一个简单的示例代码，通过BestHTTP插件可以很容易地实现WebSocket通信。
