使用HostedService扩展SuperSocketService再通过配置启动SuperSocket时，提示端口占用

[kasnti]

beta6中出现该问题，beta3无问题 使用源码中samples里的ConfigSample项目案例，该案例在配置文件中写好了socket端口信息 在该案例中，新建CustomAppService类：

public class CustomAppService<TReceivePackageInfo> : SuperSocketService<TReceivePackageInfo>
    {
        public CustomAppService(IServiceProvider serviceProvider, IOptions<ServerOptions> serverOptions) : base(serviceProvider, serverOptions)
        {
        }

        protected override ValueTask OnSessionConnectedAsync(IAppSession session)
        {
            return base.OnSessionConnectedAsync(session);
        }
        protected override ValueTask OnSessionClosedAsync(IAppSession session)
        {
            return base.OnSessionClosedAsync(session);
        }

        protected override ValueTask<bool> OnSessionErrorAsync(IAppSession session, PackageHandlingException<TReceivePackageInfo> exception)
        {
            return base.OnSessionErrorAsync(session, exception);
        }
    }

在Program.cs中注册使用该服务(第二行，其余都是案例原本的代码)：

var host = SuperSocketHostBuilder.Create<TextPackageInfo, LinePipelineFilter>(args)
                .UseHostedService<CustomAppService<TextPackageInfo>>()
                .UsePackageHandler(async (s, p) =>
                {
                    await s.SendAsync(Encoding.UTF8.GetBytes(p.Text + "\r\n"));
                })
                .ConfigureLogging((hostCtx, loggingBuilder) =>
                {
                    // register your logging library here
                    loggingBuilder.AddConsole();
                }).Build();

启动项目，提示端口重复占用

fail: TcpChannelCreator[0]
      The listener[Ip=Any, Port=4040, Security=None, Path=, BackLog=0, NoDelay=False] failed to start.
System.Net.Sockets.SocketException (10048): 通常每个套接字地址(协议/网络地址/端口)只允许使用一次。
   at System.Net.Sockets.Socket.UpdateStatusAfterSocketErrorAndThrowException(SocketError error, String callerName)
   at System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress)
   at System.Net.Sockets.Socket.Bind(EndPoint localEP)
   at SuperSocket.Server.TcpChannelCreator.Start()

已确认过并不是其他程序占用了端口，因为更换了beta3的包则无该问题

This problem already has been fixed. But the fix has not been released to nuget. Anyway, you can get the fix from nightly build packages: https://www.myget.org/feed/Packages/supersocket

i can use net8 asp webapi , supersocket2.0 beta.26, find the same issue: 1.error message: TcpConnectionListener[0] The listener[Ip=Any, Port=9999, Security=None, Path=, BackLog=0, NoDelay=False] failed to start. System.Net.Sockets.SocketException (10048): Only one usage of each socket address (protocol/network address/port) is normally permitted. at System.Net.Sockets.Socket.UpdateStatusAfterSocketErrorAndThrowException(SocketError error, Boolean disconnectOnFailure, String callerName) at System.Net.Sockets.Socket.DoBind(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Bind(EndPoint localEP) at SuperSocket.Server.Connection.TcpConnectionListener.Start()

2.source code: host = SuperSocketHostBuilder .Create<TextPackageInfo, LinePipelineFilter>() .ConfigureErrorHandler( (session, exception) => { _logger.LogError($"Tcp Error Handler: {exception.Message}"); return ValueTask.FromResult(false); } ) .ConfigureSuperSocket(opts => { foreach (var listener in _serverOptions.Value.Listeners) { opts.AddListener( new ListenOptions() { Ip = listener.Ip, Port = listener.Port } ); } }) .UseHostedService<CustomAppService>() // .UseSession() .UseClearIdleSession() .UseSessionHandler( onClosed: async (s, v) => { try { // Session管理 // await _gpsTrackerSessionManager.TryRemoveBySessionId(s.SessionID); } catch { // ignored } } ) .UsePackageHandler( async (s, packet) => { // 处理包 _logger.LogInformation($"rev:{packet.Text}"); } ) .UseInProcSessionContainer() .BuildAsServer();

await host.StartAsync();

could you have suggestion?

[ArvGoodman]

the reason is that serveroption part conflicts configuration json file with code serveroption setting .
