自定义AppSession

TelnetSession.cs

 1     public  class TelnetSession:AppSession<TelnetSession>
 2     {
 3         protected override void OnSessionStarted()
 4         {
 5             Send("Welcome to SuperSocket Telnet Server");
 6         }

 8         protected override void HandleUnknownRequest(SuperSocket.SocketBase.Protocol.StringRequestInfo requestInfo)
 9         {
10             Send("Unknow request");
11         }
12 
13         protected override void HandleException(Exception e)
14         {
15             this.Send("Application error: {0}", e.Message);
16         }
17 
18         protected override void OnSessionClosed(CloseReason reason)
19         {
20             //add you logics which will be executed after the session is closed
21             base.OnSessionClosed(reason);
22         }

Echo.cs

1     public class Echo : CommandBase<TelnetSession, StringRequestInfo>
2     {
3         public override void ExecuteCommand(TelnetSession session, StringRequestInfo requestInfo)
4         {
5             session.Send(requestInfo.Body);
6         }

在这个command代码中，你可以看到类ECHO的父类是CommandBase<AppSession, StringRequestInfo>，它有一个泛型参数AppSession。是的，它是默认的AppSession类。如果你在你的系统中使用你自己建立的AppSession类，那么你必须将你自己定义的AppSession类传进去，否则你的服务器无法发现这个Command：

Add.cs

1     public class Add : CommandBase<TelnetSession, StringRequestInfo>
2     {
3         public override void ExecuteCommand(TelnetSession session, StringRequestInfo requestInfo)
4         {
5             session.Send(requestInfo.Parameters.Select(p => Convert.ToInt32(p)).Sum().ToString());
6         }
7     }
