C#編程 socket編程之unity聊天室

上面咱們建立了tcp的客戶端和服務端，可是隻能進行消息的一次收發。此次咱們作一個unity的簡易聊天室，使用了線程，能夠使用多個客戶端鏈接服務器，而且一個客戶端給服務器發消息後，服務器會將消息羣發給全部客戶端。

 

服務器端分爲Program和Client，在Program中進行Ip和端口的綁定並與客戶端創建鏈接，消息的接收和發送放在Client中、

服務端之Program：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Net.WebSockets;
using System.Text;
using System.Threading.Tasks;

namespace _022_聊天室_socket_tcp服務器端 {
    class Program {
        static  List<Client> clientList = new List<Client>();

        // 廣播消息
        public static void BroadcastMessage(string message)
        {
            var notConnectedList = new List<Client>();
            foreach (var client in clientList)
            {
                if (client.Connected)
                    client.SendMessage(message);
                else
                {
                    notConnectedList.Add(client);
                }
            }
            foreach (var temp in notConnectedList)
            {
                clientList.Remove(temp);
            }
        }
        static void Main(string[] args) {
            Socket tcpServer = new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);
            tcpServer.Bind(new IPEndPoint(IPAddress.Parse("192.168.1.101"),7788));

            tcpServer.Listen(100);
            Console.WriteLine("server running...");

            while (true)
            {
                Socket clientSocket = tcpServer.Accept();
                Console.WriteLine("a client is connected !");
                Client client = new Client(clientSocket);//把與每一個客戶端通訊的邏輯(收發消息)放到client類裏面進行處理
                clientList.Add(client);
            }
            
        }
    }
}

服務端之Client：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Sockets;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace _022_聊天室_socket_tcp服務器端 {
    // 用來跟客戶端作通訊 
    class Client
    {
        private Socket clientSocket;
        private Thread t;
        private byte[] data = new byte[1024];//這個是一個數據容器

        public Client(Socket s)
        {
            clientSocket = s;
            //啓動一個線程 處理客戶端的數據接收
            t = new Thread(ReceiveMessage);
            t.Start();
        }

        // 接收數據
        private void ReceiveMessage()
        {
            //一直接收客戶端的數據
            while (true)
            {
                //在接收數據以前  判斷一下socket鏈接是否斷開
                if (clientSocket.Poll(10, SelectMode.SelectRead))
                {
                    clientSocket.Close();
                    break;//跳出循環 終止線程的執行
                }
                
                int length = clientSocket.Receive(data);
                string message = Encoding.UTF8.GetString(data, 0, length);
                //接收到數據的時候 要把這個數據 分發到客戶端
                //廣播這個消息
                Program.BroadcastMessage(message);
                Console.WriteLine("收到了消息:"+message);
            }
        }

        // 發送消息
        public void SendMessage(string message)
        {
            byte[] data = Encoding.UTF8.GetBytes(message);
            clientSocket.Send(data);
        }

        // 判斷是否鏈接
        public bool Connected
        {
            get { return clientSocket.Connected; }
        }
    }
}

 

客戶端：由於是基於unity的聊天室，因此首先建立簡單的UI界面

代碼：

using UnityEngine;
using System.Collections;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading;

public class ChatManager : MonoBehaviour
{
    public string ipaddress = "192.168.1.101";
    public int port = 7788;
    public UIInput textInput;
    public UILabel chatLabel;

    private Socket clientSocket;
    private Thread t;
    private byte[] data = new byte[1024];//數據容器
    private string message = "";//消息容器

	void Start () {
	    ConnectToServer();
	}
	
	void Update () {
	    if (message != null && message != "")
	    {
	        chatLabel.text += "\n" + message;
	        message = "";//清空消息
	    }
	}

    void ConnectToServer()
    {
        clientSocket = new Socket(AddressFamily.InterNetwork,SocketType.Stream, ProtocolType.Tcp);
        //跟服務器端創建鏈接
        clientSocket.Connect( new IPEndPoint(IPAddress.Parse(ipaddress),port) );

        //建立一個新的線程 用來接收消息
        t = new Thread(ReceiveMessage);
        t.Start();
    }

    // 這個線程方法 用來循環接收消息
    void ReceiveMessage()
    {
        while (true)
        {
            if (clientSocket.Connected == false)
                break;

            int length = clientSocket.Receive(data);
            message = Encoding.UTF8.GetString(data, 0, length);
            //chatLabel.text += "\n" + message;
        }
    }

    // 發送消息
    void SendMessage(string message)
    {
        byte[] data = Encoding.UTF8.GetBytes(message);
        clientSocket.Send(data);
    }

    // 發送按鈕點擊
    public void OnSendButtonClick()
    {
        string value = textInput.value;
        SendMessage(value);
        textInput.value = "";
    }

    void OnDestroy()
    {
        clientSocket.Shutdown(SocketShutdown.Both);
        
        clientSocket.Close();//關閉鏈接
    }
}
