SuperSocket框架中BinaryRequestInfo协议的使用

 

一、开发环境

　　1.Windows 10 企业版 64位

　　2.Microsoft Visual Studio 2017 企业版

二、项目开始

　　1.新建控制台程序，项目名称“BinarySuperSocket”，.net框架“4.7.1”

　　

　　2.安装SuperSocket的包，点击 “工具->NuGet包管理器->程序包管理器控制台”

　　

　　　输入“install-package supersocket”，然后回车，提示安装成功，见下图

    　

　　

　　输入“install-package supersocket.engine”，然后回车，提示安装成功，见下图

 　　

　　

　　3.新建BinarySession类

　　

　　

using SuperSocket.SocketBase;
using SuperSocket.SocketBase.Protocol;

namespace BinarySuperSocket
{
    public class BinarySession : AppSession<BinarySession, BinaryRequestInfo>
    {
    }
}

 　　4.新建BinaryServer类

　　

using SuperSocket.SocketBase;
using SuperSocket.SocketBase.Protocol;

namespace BinarySuperSocket
{
    public class BinaryServer : AppServer<BinarySession, BinaryRequestInfo>
    {

        public BinaryServer(IReceiveFilterFactory<BinaryRequestInfo> protocol) : base(protocol)
        {
        }
    }
}

　　5.新建BinaryReceiveFilter类

　　

using System;
using SuperSocket.SocketBase.Protocol;

namespace BinarySuperSocket
{
    public class BinaryReceiveFilter : IReceiveFilter<BinaryRequestInfo>
    {
        public int LeftBufferSize { get; set; }

        public IReceiveFilter<BinaryRequestInfo> NextReceiveFilter { get; set; }

        public FilterState State { get; set; }

        public BinaryRequestInfo Filter(byte[] readBuffer, int offset, int length, bool toBeCopied, out int rest)
        {
            byte[] value = new byte[length];
            Array.Copy(readBuffer, offset, value, 0, length);
            BinaryRequestInfo binaryRequestInfo = new BinaryRequestInfo("key", value);
            rest = length - value.Length;
            return binaryRequestInfo;
        }

        public void Reset()
        {
        }
    }
}

　　6.新建BinaryReceiveFilterFactory类

　　

using System.Net;
using SuperSocket.SocketBase;
using SuperSocket.SocketBase.Protocol;

namespace BinarySuperSocket
{
    public class BinaryReceiveFilterFactory : IReceiveFilterFactory<BinaryRequestInfo>
    {
        public IReceiveFilter<BinaryRequestInfo> CreateFilter(IAppServer appServer, IAppSession appSession, IPEndPoint remoteEndPoint)
        {
            BinaryReceiveFilter binaryReceiveFilter = new BinaryReceiveFilter();
            return binaryReceiveFilter;
        }
    }
}

　　7.Main函数调用

　　

using System;
using System.Text;

namespace BinarySuperSocket
{
    class Program
    {
        static void Main(string[] args)
        {
            BinaryReceiveFilterFactory filterFactory = new BinaryReceiveFilterFactory();
            BinaryServer server = new BinaryServer(filterFactory);

            server.NewSessionConnected += Server_NewSessionConnected;
            server.SessionClosed += Server_SessionClosed;
            server.NewRequestReceived += Server_NewRequestReceived;

            bool b = server.Setup(7788);//设置端口号
            Console.WriteLine($"设置端口号结果：{b}");

            if (b)
            {
                bool s = server.Start();//开始服务
                Console.WriteLine($"服务开启结果：{s}");
            }

            Console.ReadKey();
        }

        private static void Server_NewRequestReceived(BinarySession session, SuperSocket.SocketBase.Protocol.BinaryRequestInfo requestInfo)
        {
            StringBuilder sb = new StringBuilder();
            Array.ForEach(requestInfo.Body, b => sb.Append($"{b} "));
            Console.WriteLine($"接收到客户端 {session.Config.Ip}:{session.Config.Port} 的数据：");
            Console.WriteLine($"字节数组形式：{sb.ToString()}");
            Console.WriteLine($" ASCII码转换：{Encoding.ASCII.GetString(requestInfo.Body)}");
        }

        private static void Server_SessionClosed(BinarySession session, SuperSocket.SocketBase.CloseReason value)
        {
            Console.WriteLine($"客户端 {session.Config.Ip}:{session.Config.Port} 断开，原因：{value.ToString()}");
        }

        private static void Server_NewSessionConnected(BinarySession session)
        {
            Console.WriteLine($"客户端 {session.Config.Ip}:{session.Config.Port} 已连接");
        }
    }
}
