在C#中使用异步Socket编程实现TCP网络服务的C/S的通讯构架(二)----使用方法

 

一.TcpSvr的使用方法
A.测试程序:
using System;
using Ibms.Net.TcpCSFramework;
using System.Collections;
using System.Net.Sockets;

namespace Ibms.Test
{
 /// <summary>
 /// 测试TcpSvr的类
 /// </summary>
 public class TestTcpSvr
 {
  
  public TestTcpSvr()
  {
   
  }

  
  public static  void Main()
  {
   try
   {

    Console.WriteLine("Begin to Test TcpSvr class...");

    TestTcpSvr tts = new TestTcpSvr();

    //TcpSvr svr = new TcpSvr(9050,4);//默认使用Encoding.Default编码方式
    TcpSvr svr = new TcpSvr(9050,4,new Coder(Coder.EncodingMothord.UTF8));

    svr.Resovlver = new DatagramResolver("##");

    //定义服务器的4个事件

    //服务器满
    svr.ServerFull += new NetEvent(tts.ServerFull);

    //新客户端连接
    svr.ClientConn += new NetEvent(tts.ClientConn);

    //客户端关闭
    svr.ClientClose += new NetEvent(tts.ClientClose);

    //接收到数据
    svr.RecvData += new NetEvent(tts.RecvData);
    
    //命令控制循环
    while(true)
    {
     Console.Write(">");

     string cmd=Console.ReadLine();

     //退出测试程序
     if(cmd.ToLower() == "exit")
     {
      break;
     }

     //停止服务器程序
     if(cmd.ToLower() == "stop")
     {
      svr.Stop();
      
      Console.WriteLine("Server is Stop.");

      continue;
     }

     //运行服务器程序
     if(cmd.ToLower() == "start")
     {
      svr.Start();

      Console.WriteLine("Server is listen...{0}",
       svr.ServerSocket.LocalEndPoint.ToString());

      continue;
     }

     //察看服务器在线客户端数目和容量
     if(cmd.ToLower() == "count")
     {
      Console.WriteLine("Current count of Client is {0}/{1}",
       svr.SessionCount,svr.Capacity);
      continue;
     }

     //发送数据到客户端格式:send [Session] [stringData]
     if(cmd.ToLower().IndexOf("send") !=-1)
     {
      cmd = cmd.ToLower();

      string[] para = cmd.Split(' ');

      if(para.Length ==3)
      {
       
       Session client = (Session)svr.SessionTable[ new SessionId( int.Parse
        (para[1]))];

       if(client !=null)
       {
        svr.Send(client, para[2]);
       }
       else
       {
        Console.WriteLine("The Session is Null");
       }
       
      }
      else
      {
       Console.WriteLine("Error Command");
      }

      continue;
     }

     //从服务器上踢掉一个客户端
     if(cmd.ToLower().IndexOf("kick") !=-1)
     {
      cmd = cmd.ToLower();

      string[] para = cmd.Split(' ');
      
      if(para.Length ==2)
      {
       Session client = (Session)svr.SessionTable[ new SessionId( int.Parse
        (para[1]))];

       if(client !=null)
       {
        svr.CloseSession(client);
       }
       else
       {
        Console.WriteLine("The Session is Null");
       }
      }
      else
      {
       Console.WriteLine("Error command");
      }
      
      continue;

     }

     //列出服务器上所有的客户端信息
     if(cmd.ToLower() == "list")
     {
      int i=0;

      foreach( Session Client in svr.SessionTable.Values)
      {
       if(Client !=null)
       {
        i++;
        string info = string.Format("{0} Client:{1} connected server Session:{2}. Socket Handle:{3}",
         i,
         Client.ClientSocket.RemoteEndPoint.ToString(),
         Client.ID,
         Client.ClientSocket.Handle);

        Console.WriteLine( info );
       }
       else
       {
        i++;

        string info = string.Format("{0} null Client", i);
        Console.WriteLine(info);

       }
      }

      continue;
      
     }

     Console.WriteLine("Unkown Command");


    }//end of while

    Console.WriteLine("End service");
   }
   catch(Exception ex)
   {
    Console.WriteLine(ex.ToString());
   }

  }

  void ClientConn(object sender, NetEventArgs e)
  {
   string info = string.Format("A Client:{0} connect server Session:{1}. Socket Handle:{2}",
    e.Client.ClientSocket.RemoteEndPoint.ToString(),
    e.Client.ID,e.Client.ClientSocket.Handle);

   Console.WriteLine( info );

   Console.Write(">");
  }
  
  void ServerFull(object sender, NetEventArgs e)
  {
   string info = string.Format("Server is full.the Client:{0} is refused",
    e.Client.ClientSocket.RemoteEndPoint.ToString());

   //Must do it
   //服务器满了,必须关闭新来的客户端连接
   e.Client.Close();

   Console.WriteLine(info);

   Console.Write(">");

  }

  void ClientClose(object sender, NetEventArgs e)
  {
   string info ;

   if( e.Client.TypeOfExit == Session.ExitType.ExceptionExit)
   {
    info= string.Format("A Client Session:{0} Exception Closed.",
     e.Client.ID);
   }
   else
   {
    info= string.Format("A Client Session:{0} Normal Closed.",
     e.Client.ID);
   }

   Console.WriteLine( info );

   Console.Write(">");
  }

  void RecvData(object sender, NetEventArgs e)
  {
   string info = string.Format("recv data:{0} from:{1}.",e.Client.Datagram, e.Client);

   Console.WriteLine( info );
   TcpSvr svr = (TcpSvr) sender;

   //测试把收到的数据返回给客户端
   svr.Send(e.Client, e.Client.Datagram);

   Console.Write(">");
   
  }

 }
}

B.说明:
使用命令来操作服务器
exit  退出
start 开始服务
kick 关闭客户端
send 发送数据
list 列出所有客户端的状态
count 客户端计数

先启动服务运行start,等待客户端连接。
然后可以使用list,count察看当前的连接状况


每个事件都有相应函数,客户就在事件处理函数中处理自己的业务逻辑
可以通过继承特化自己的服务器应用,基本的框架不变

二.TcpCli的使用方法
A.测试程序:
using System;
using Ibms.Net.TcpCSFramework;

namespace Ibms.Test
{
 /// <summary>
 /// TestTcpClient 的摘要说明。
 /// </summary>
 public class TestTcpClient
 {
  public TestTcpClient()
  {
   //
   // TODO: 在此处添加构造函数逻辑
   //
  }
  public static void Test()
  {
   Console.WriteLine("Begin to Test TcpCli Class..");

   TestTcpClient test = new TestTcpClient();

   TcpCli cli = new TcpCli( new Coder(Coder.EncodingMothord.UTF8));

   cli.Resovlver = new DatagramResolver("##");

   cli.ReceivedDatagram += new NetEvent(test.RecvData);

   cli.DisConnectedServer += new NetEvent(test.ClientClose);

   cli.ConnectedServer += new NetEvent(test.ClientConn);
   
   try
   {
    //命令控制循环
    while(true)
    {
     Console.Write(">");

     string cmd=Console.ReadLine();

     if(cmd.ToLower() == "exit")
     {
      break;
     }

     if(cmd.ToLower() == "close")
     {
      cli.Close();
      

      continue;
     }

     if(cmd.ToLower().IndexOf("conn")!=-1)
     {
      cmd = cmd.ToLower();

      string[] para = cmd.Split(' ');

      if(para.Length ==3)
      {
      
       cli.Connect(para[1],int.Parse(para[2]));
      }
      else
      {
       Console.WriteLine("Error Command");
      }

      continue;
     }

     if(cmd.ToLower().IndexOf("send") !=-1)
     {
     
      
      cmd = cmd.ToLower();

      string[] para = cmd.Split(' ');

      if(para.Length ==2)
      {
      
       cli.Send(para[1]);

      
      }
      else
      {
       Console.WriteLine("Error Command");
      }

      continue;
     }

    
     Console.WriteLine("Unkown Command");


    }//end of while

    Console.WriteLine("End service");
   }
   catch(Exception ex)
   {
    Console.WriteLine(ex.ToString());
   }


  }

  void ClientConn(object sender, NetEventArgs e)
  {
   string info = string.Format("A Client:{0} connect server :{1}",e.Client,
    e.Client.ClientSocket.RemoteEndPoint.ToString());

   Console.WriteLine( info );

   Console.Write(">");
  }
  
  void ClientClose(object sender, NetEventArgs e)
  {
   string info ;

   if( e.Client.TypeOfExit == Session.ExitType.ExceptionExit)
   {
    info= string.Format("A Client Session:{0} Exception Closed.",
     e.Client.ID);
   }
   else
   {
    info= string.Format("A Client Session:{0} Normal Closed.",
     e.Client.ID);
   }

   Console.WriteLine( info );

   Console.Write(">");
  }

  void RecvData(object sender, NetEventArgs e)
  {
   string info = string.Format("recv data:{0} from:{1}.",e.Client.Datagram, e.Client);

   Console.WriteLine( info );
   
   Console.Write(">");
   
  }
 }
}

B.说明:
先建立连接,Conn 192.9.207.214 9050
然后可以Send 数据
最后关闭连接Close

三.编码器
如果你要加密你的报文,需要一个你自己的Coder
从Coder类继承一个如MyCoder类,然后重载编码和解码函数。
使用方法:

TcpCli cli = new TcpCli( new MyCoder());

就可以在客户端使用该编码器了。
四.报文解析器
与编码器同样的实现方法。
