unity3D-----------socket客户端、服务器（简单）

利用socket简单的实现，客户端和服务器之间的通信。

客户端：

using UnityEngine;

using System.Collections;

using System.Text;

using System.Net;

using System.Net.Sockets;

using System.IO;

public class client : MonoBehaviour {
void Start () {

        ConncetServer();
}

    void ConncetServer()

    {

        IPAddress ipAdr = IPAddress.Parse("10.130.28.9");

        IPEndPoint ipEp=new IPEndPoint(ipAdr,7000);

        Socket clientScoket=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);

        clientScoket.Connect(ipEp);

        string output="client requeset";

        byte[] concent=Encoding.UTF8.GetBytes(output);

        clientScoket.Send(concent);

        byte[] response=new byte[1024];

        int bytesRead = clientScoket.Receive(response);

        string input = Encoding.UTF8.GetString(response,0,bytesRead);

        print("Client request:"+input);

        clientScoket.Shutdown(SocketShutdown.Both);

        clientScoket.Close();

    }

}

服务器：

using UnityEngine;

using System.Collections;

using System.Collections;

using System.Net;

using System.IO;

using System.Net.Sockets;

using System.Text;

public class Connet : MonoBehaviour {

// Use this for initialization
void Start () {

        OpenServer();
}

    void OpenServer()

    {

        IPAddress ipAdr = IPAddress.Parse("10.130.28.9");

        IPEndPoint ipEp = new IPEndPoint(ipAdr,7000);

        //creat a socket

        Socket serverScoket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);

        //bind the socket

        serverScoket.Bind(ipEp);

        //listen

        serverScoket.Listen(20);

        while(true)

        {

            Socket client = serverScoket.Accept();

            byte[] request=new byte[512];

            //receive

            int bytesRead = client.Receive(request);

            string input = Encoding.UTF8.GetString(request,0,bytesRead);//按照字符编码得到字符串

            print("server request:"+input);

            string output = "server request true";

            byte[] concent = Encoding.UTF8.GetBytes(output);

            client.Send(concent);

            client.Shutdown(SocketShutdown.Both);//关闭接收和发送

            client.Close();

        }

    }

}
