Unity客户端 链接 服务器端的例子

Unity客户端 链接 服务器端的例子

一个带GUI的例子，亲测可用。可以使用这个封装一套TCP接口

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

public class ClientHandler : MonoBehaviour
{

    const int portNo = 8000;
    private TcpClient _client;
    private byte[] data;

    public string nickName = "";
    public string message = "";
    public string sendMsg = "";
    // Use this for initialization
    void OnGUI()
    {
        nickName = GUI.TextField(new Rect(10, 10, 100, 20), nickName);
        message = GUI.TextArea(new Rect(10, 40, 300, 200), message);
        sendMsg = GUI.TextField(new Rect(10, 250, 210, 20), sendMsg);

        if (GUI.Button(new Rect(120, 10, 80, 20), "Connect"))
        {
            //Debug.Log("hello");
            this._client = new TcpClient();
            this._client.Connect("127.0.0.1", portNo);

            data = new byte[this._client.ReceiveBufferSize];

            //SendMyMessage(txtNick.Text);
            SendMyMessage(nickName);

            this._client.GetStream().BeginRead(data, 0, System.Convert.ToInt32(this._client.ReceiveBufferSize), ReceiveMessage, null);
        };

        if (GUI.Button(new Rect(230, 250, 80, 20), "Send"))
        {
            SendMyMessage(sendMsg);
            sendMsg = "";
        };
    }

    /// <summary>
    /// 向服务器发送数据（发送聊天信息）
    /// </summary>
    /// <param name="message"></param>
    public void SendMyMessage(string message)
    {
        try
        {
            NetworkStream ns = this._client.GetStream();

            byte[] data = Encoding.UTF8.GetBytes(message);

            ns.Write(data, 0, data.Length);
            ns.Flush();
        }
        catch (Exception ex)
        {
            Debug.Log("Error:" + ex);
        }
    }
    /// <summary>
    /// 接收服务器的数据（聊天信息）
    /// </summary>
    /// <param name="ar"></param>
    public void ReceiveMessage(IAsyncResult ar)
    {
        try
        {
            int bytesRead;
            bytesRead = this._client.GetStream().EndRead(ar);

            if (bytesRead < 1)
            {
                return;
            }
            else
            {
                message += Encoding.UTF8.GetString(data, 0, bytesRead).ToString();
            }

            this._client.GetStream().BeginRead(data, 0, System.Convert.ToInt32(this._client.ReceiveBufferSize), ReceiveMessage, null);
        }
        catch (Exception ex)
        {
            print("Error:" + ex);
        }
    }
    void Start()
    {

    }
    // Update is called once per frame
    void Update()
    {

    }
}
