Question

我是DotNetty的新手，我试图从套接字接收一个简单的请求（二进制格式）

我要反序列化的课程是

public class PKKeepAlive
{
    public uint PacketType => 12003;
}

我尝试使用的处理程序是

    public class KeepAliveResponseHandler : SimpleChannelInboundHandler<PKKeepAlive>
{
    public override void ChannelRead(IChannelHandlerContext ctx, object msg)
    {
        var obj = msg as IByteBuffer;

        base.ChannelRead(ctx, msg);
    }

    public override void ExceptionCaught(IChannelHandlerContext context, Exception exception)
    {
        Console.WriteLine("Exception: " + exception);
        context.CloseAsync();
    }

    protected override void ChannelRead0(IChannelHandlerContext ctx, PKKeepAlive packet)
    {
        string message = packet.ToString();

        Console.WriteLine($"Quote of the Moment: {message.Substring(6)}");
        ctx.CloseAsync();
    }
}

这是在WPF示例应用程序中注册并执行

private async void MainWindow_Loaded(object sender, RoutedEventArgs e)
    {

        var group = new MultithreadEventLoopGroup();

        var bootstrap = new Bootstrap();
        bootstrap
            .Group(group)
            .Channel<TcpSocketChannel>()
            .Option(ChannelOption.TcpNodelay, true)
            .Handler(new ActionChannelInitializer<ISocketChannel>(channel =>
            {
                //channel.Pipeline.AddLast("LoginResponse", new Temp());
                channel.Pipeline.AddLast("KeepAliveResponse", new KeepAliveResponseHandler());

            }));


        IPAddress ip = IPAddress.Parse("192.168.0.116");

        IChannel bootstrapChannel = await bootstrap.ConnectAsync(new IPEndPoint(ip, 20000));


        var login = new LoginRequest { UserName = "if" };

        var bytes = login.Serialize();
        IByteBuffer buffer = Unpooled.WrappedBuffer(bytes);

        await bootstrapChannel.WriteAndFlushAsync(buffer);

    }

我遇到的问题是我可以在公共覆盖void ChannelRead（IChannelHandlerContext ctx，object msg）方法上有一个断点，我看到我有8个字节可读，但它没有停止on protected override void ChannelRead0（IChannelHandlerContext ctx，PKKeepAlive packet）我认为我应该让包刚刚反序列化

在我的真实场景中考虑我必须根据uint PacketType处理不同的数据包（实际上在超级插件中我读取该值并执行切换）

对此有何建议？感谢

无法启动ChannelRead0
