[Unity网络]同步Socket

1.Socket通信的基本流程

2.客户端

using System.Net.Sockets;
using System.Text;
using UnityEngine;
using UnityEngine.UI;

public class TestSocket : MonoBehaviour
{
    private Socket socket;
    public InputField inputField;
    public Text text;

    void Start()
    {
        //InterNetwork:使用IPv4
        //InterNetworkV6:使用IPv6
        socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    }

    public void TestConnect()
    {
        //Connect
        socket.Connect("127.0.0.1", 8888);
    }

    public void TestSend()
    {
        //Send
        byte[] writeBytes = Encoding.Default.GetBytes(inputField.text);
        socket.Send(writeBytes);

        //Receive
        byte[] readBytes = new byte[1024];
        int count = socket.Receive(readBytes);
        text.text = Encoding.Default.GetString(readBytes, 0, count);

        //Close
        socket.Close();
    }
}

3.服务端

using System;
using System.Net;
using System.Net.Sockets;
using System.Text;

namespace TestSocket
{
    class Program
    {
        static void Main(string[] args)
        {
            Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            //Bind
            IPAddress iPAddress = IPAddress.Parse("127.0.0.1");
            IPEndPoint iPEndPoint = new IPEndPoint(iPAddress, 8888);
            socket.Bind(iPEndPoint);

            //Listen
            socket.Listen(0);
            Console.WriteLine("Listen");

            while (true)
            {
                //Accept
                Socket clientSocket = socket.Accept();
                Console.WriteLine("Accept");

                //Receive
                byte[] readBytes = new byte[1024];
                int count = clientSocket.Receive(readBytes);
                string readStr = Encoding.Default.GetString(readBytes, 0, count);
                Console.WriteLine("Receive:" + readStr);

                //Send
                byte[] writeBytes = Encoding.Default.GetBytes(readStr);
                clientSocket.Send(writeBytes);
            }
        }
    }
}
