C# superSocket简单示例

两个端,一个服务端,一个客户端。
都是控制台程序。
显然地,服务端的要引用superSocket,但引用后编译时候会提示,所以最终引用的内容如图所示:

superSocket内置了log4net,所以会有图中所示。


然后上代码:

服务端:

using System;
using System.Linq;
using SuperSocket.SocketBase;
using SuperSocket.SocketBase.Protocol;

namespace superSocketServer
{
    class Program
    {
        static AppServer appServer { get; set; }
        static void Main(string[] args)
        {
            appServer = new AppServer();


            //Setup the appServer
            if (!appServer.Setup(2012)) //Setup with listening port
            {
                Console.WriteLine("Failed to setup!");
                Console.ReadKey();
                return;
            }           

            //Try to start the appServer
            if (!appServer.Start())
            {
                Console.WriteLine("Failed to start!");
                Console.ReadKey();
                return;
            }


            Console.WriteLine("The server started successfully, press key 'q' to stop it!");

            //1.
            appServer.NewSessionConnected += new SessionHandler(appServer_NewSessionConnected);
            appServer.SessionClosed += appServer_NewSessionClosed;

            //2.
            appServer.NewRequestReceived += new RequestHandler(appServer_NewRequestReceived);

            while (Console.ReadKey().KeyChar != 'q')
            {
                Console.WriteLine();
                continue;
            }

            //Stop the appServer
            appServer.Stop();

            Console.WriteLine("The server was stopped!");
            Console.ReadKey();
        }

        //1.
        static void appServer_NewSessionConnected(AppSession session)
        {
            Console.WriteLine($"服务端得到来自客户端的连接成功");

            var count = appServer.GetAllSessions().Count();
            Console.WriteLine("~~" + count);
            session.Send("Welcome to SuperSocket Telnet Server");
        }

        static void appServer_NewSessionClosed(AppSession session, CloseReason aaa)
        {
            Console.WriteLine($"服务端 失去 来自客户端的连接" + session.SessionID + aaa.ToString());
            var count = appServer.GetAllSessions().Count();
            Console.WriteLine(count);
        }

        //2.
        static void appServer_NewRequestReceived(AppSession session, StringRequestInfo requestInfo)
        {
            Console.WriteLine(requestInfo.Key);
            session.Send(requestInfo.Body);           
        }



    }
}

客户端

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

namespace superSocketClient
{
    class Program
    {
        static Socket socketClient { get; set; }
        static void Main(string[] args)
        {
            //创建实例
            socketClient = new Socket(SocketType.Stream, ProtocolType.Tcp);
            IPAddress ip = IPAddress.Parse("192.168.0.121");
            IPEndPoint point = new IPEndPoint(ip, 2012);
            //进行连接
            socketClient.Connect(point);


            //不停的接收服务器端发送的消息
            Thread thread = new Thread(Recive);
            thread.IsBackground = true;
            thread.Start();


            ////不停的给服务器发送数据
            Thread thread2 = new Thread(Send);
            thread2.IsBackground = true;
            thread2.Start();

            Console.ReadKey();
        }

        /// 
        /// 接收消息
        /// 
        /// 
        static void Recive()
        {
          //  为什么用telnet客户端可以,但这个就不行。
            while (true)
            {
                //获取发送过来的消息
                byte[] buffer = new byte[1024 * 1024 * 2];
                var effective = socketClient.Receive(buffer);
                if (effective == 0)
                {
                    break;
                }
                var str = Encoding.UTF8.GetString(buffer, 0, effective);
                Console.WriteLine("来自服务器 --- " + str);
                Thread.Sleep(2000);
            }
        }


        static void Send()
        {          
            int i = 0;
            int sum = 0;
            while (true)
            {
                i++;
                sum += i;
                var buffter = Encoding.UTF8.GetBytes($"ADD {sum} {sum + 1}" + "\r\n");
                var temp = socketClient.Send(buffter);
                Console.WriteLine(i);
                Thread.Sleep(1000);
            }

        }
    }
}

以上代码可直接运行,客户端与服务器可以互发消息。
注意这只是一个基本应用,如果需要企业级的,高级一些的应用,则需要
自写 Session、Server,需要继承CommandBase和重载ExecuteCommand。
如:

using System.Linq;
using SuperSocket.SocketBase;
using SuperSocket.SocketBase.Command;
using SuperSocket.SocketBase.Protocol;

namespace superSocketServer
{
    public class ADD : CommandBase
    {
        public override void ExecuteCommand(AppSession session, StringRequestInfo requestInfo)
        {
            session.Send(requestInfo.Parameters.Select(p=>int.Parse(p)).Sum().ToString());
        }
    }
}

这样的话,客户端给服务器发消息,发诸如 “ ADD 3 4 \r\n” 这样的字符串给服务端,服务端就可以执行上面的这段代码,并且再返回给客户端。


再然后,如果命令是很多的,也不能这样写死,就要使用C#的反射,动态地根据客户端传来的字符串,然后调用服务端的响应函数。再返回给客户端内容。
这里只是说一个基本思路。
具体的格式,由客户端与服务端具体约定。

完毕。
