在上一篇文章中，简单的封装了一下服务端中相关的socket对象，为了可以更方便的使用。所以在本篇中，进一步封装一下在unity中的相关客户端类

封装客户端类，首先采用单例模式，然后采用两个队列来存储我们相关的收发信息

    private static NetManager instance;public static NetManager Instance => instance;private Socket socket;//客户端socketprivate Queue<string> receiveQue = new Queue<string>();//接收队列，子线程放，主线程拿取private Queue<string> sendQue = new Queue<string>();//发送队列，主线程放，子线程拿取并发送private bool isConnteced;private int num;//接收信息字节大小private byte[] reveiveBuffer = new byte[1024 * 5];

连接函数

    public void Connect(string ip, int port){if (socket is null)socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);IPEndPoint ipPoint = new IPEndPoint(IPAddress.Parse(ip), port);try{socket.Connect(ipPoint);isConnteced = true;ThreadPool.QueueUserWorkItem(SendMsg);ThreadPool.QueueUserWorkItem(ReceiveMsg);}catch (SocketException s){if (s.ErrorCode == 10061)print("服务器拒绝连接");elseprint("连接出错 " + s.ErrorCode);return;}}

处理信息发送和接收

    public void Send(string info){sendQue.Enqueue(info);}public void Receive(){if (receiveQue.Count > 0){print(receiveQue.Dequeue());}}

发送消息时，主线程只用把信息存进发送队列里就行，子线程负责从队列中取出信息进行发送

接收消息时，子线程负责对发送过来的字节流进行处理，将处理完毕后的信息存储接收队列里，主线程只需要不断的读取队列里的信息就行

    private void SendMsg(object obj){if (socket is null) return;while(isConnteced){if (sendQue.Count > 0){socket.Send(Encoding.UTF8.GetBytes(sendQue.Dequeue()));}}}private void ReceiveMsg(object obj){if (socket is null) return;while(isConnteced){if (socket.Available > 0){num = socket.Receive(reveiveBuffer);receiveQue.Enqueue(Encoding.UTF8.GetString(reveiveBuffer, 0, num));}}}

 

使用就很简单了，在unity中新建一个脚本，调用一下Connect方法就可以进行连接了

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Main : MonoBehaviour
{void Start(){if (NetManager.Instance is null){GameObject game = new GameObject();game.AddComponent<NetManager>();}NetManager.Instance.Connect("127.0.0.1", 8080);}
}

 新建一个ui画布，添加一个输入框，一个按钮，按钮绑定一下send方法就可以进行简单输入信息并发送了

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class Input : MonoBehaviour
{public Button button;public InputField inputField;private void Start(){button.onClick.AddListener(() =>{if (inputField.text != null){NetManager.Instance.Send(inputField.text);}});}
}

using System.Collections;
using System.Collections.Generic;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;
using UnityEngine;public class NetManager : MonoBehaviour
{private static NetManager instance;public static NetManager Instance => instance;private Socket socket;//客户端socketprivate Queue<string> receiveQue = new Queue<string>();//接收队列，子线程放，主线程拿取private Queue<string> sendQue = new Queue<string>();//发送队列，主线程放，子线程拿取并发送private bool isConnteced;private int num;//接收信息字节大小private byte[] reveiveBuffer = new byte[1024 * 5];private void Awake(){instance = this;}private void Update(){Receive();}public void Connect(string ip, int port){if (socket is null)socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);IPEndPoint ipPoint = new IPEndPoint(IPAddress.Parse(ip), port);try{socket.Connect(ipPoint);isConnteced = true;ThreadPool.QueueUserWorkItem(SendMsg);ThreadPool.QueueUserWorkItem(ReceiveMsg);}catch (SocketException s){if (s.ErrorCode == 10061)print("服务器拒绝连接");elseprint("连接出错 " + s.ErrorCode);return;}}public void Send(string info){sendQue.Enqueue(info);}public void Receive(){if (receiveQue.Count > 0){print(receiveQue.Dequeue());}}public void Close(){if (socket != null){socket.Shutdown(SocketShutdown.Both);socket.Close();socket = null;}}private void SendMsg(object obj){if (socket is null) return;while(isConnteced){if (sendQue.Count > 0){socket.Send(Encoding.UTF8.GetBytes(sendQue.Dequeue()));}}}private void ReceiveMsg(object obj){if (socket is null) return;while(isConnteced){if (socket.Available > 0){num = socket.Receive(reveiveBuffer);receiveQue.Enqueue(Encoding.UTF8.GetString(reveiveBuffer, 0, num));}}}
}
