PurpleSofa 0.0.2

PurpleSofa - C# .NET async tcp server & client

feature

• Callback for 'OnOpen'(accepted or connected), 'OnMessage'(received), 'OnClose'(received none).
• Can store user value in session.
• Check timeout at regular intervals by last receive time. It's useful to detect 'half close'.
• 'OnClose' execution is taken via queue in order to avoid simultaneously many 'close'.

how to use

callback

public class Callback : PsCallback
{
    private const string Key = "inc";
    
    public override void OnOpen(PsSession session)
    {
        session.SetValue(Key, 0);
        session.ChangeIdleMilliSeconds(5000);

        int inc = session.GetValue<int>(Key);
        session.Send($"On Open inc: {inc}\n".PxToBytes());
    }

    public override void OnMessage(PsSession session, byte[] message)
    {
        int inc = session.GetValue<int>(Key);
        inc++;
        session.SetValue(Key, inc);
        session.Send($"On Message inc: {inc}\n".PxToBytes());
        if (inc > 3) session.Close();
    }

    public override void OnClose(PsSession session, PsCloseReason closeReason)
    {
        session.ClearValue(Key);
        PsLogger.Debug($"OnClose {session} {closeReason}");
    }
}

for server

public static void Main(string[] args)
{
    var server = new PsServer(new Callback());
    server.Start();
    server.WaitFor();
    // --- another thread
    // server.Shutdown();
}

for client

public static void Main(string[] args)
{
    var client = new PsClient(new CallbackClient(), "127.0.0.1", 8710);
    client.Connect();
    // ...
    client.Disconnect();
}
