TCP network components that support configuring properties

[fanliang11]

The following code is to create a TCP network component with configuration properties and configure the rule engine script to decode messages

///The following code is to create a TCP network component with configuration properties and configure the rule engine script to ///decode messages
      var config =new Dictionary<string, object>();
            config.Add("script", @"parser.Fixed(4).Handler(""function(buffer){
                    var buf = BytesUtils.Slice(buffer,1,4);
                    parser.Fixed(buffer.ReadableBytes).Result(buf);
             }"").Handler(""function(buffer){parser.Result(buffer).Complete();}"")");
           var network=  serviceProvider.ServiceProvoider.GetInstances<INetworkProvider<TcpServerProperties>>().CreateNetwork(new TcpServerProperties
           {
               ParserType = PayloadParserType.Script,
               PayloadType = PayloadType.String,
               Host = "127.0.0.1",
               Port = 322,
               ParserConfiguration = config
           });
            network.StartAsync();

The following code is used to create a TCP network component with configuration properties and configure direct to decode messages

         var network1 = serviceProvider.ServiceProvoider.GetInstances<INetworkProvider<TcpServerProperties>>().CreateNetwork(new TcpServerProperties
            {
                ParserType = PayloadParserType.Direct,
                PayloadType = PayloadType.String,
                Host = "127.0.0.1",
                Port = 321 
            });
            network1.StartAsync();

There are also two types of payload parser: fixedlength and delimited

Create tcp service for message processing

 public class TcpService : TcpBehavior, ITcpService
    { 
        private readonly IDeviceProvider _deviceProvider;
        public TcpService(IDeviceProvider deviceProvider)
        {
            _deviceProvider = deviceProvider;
        }

        public override void Load(string clientId,TcpServerProperties tcpServerProperties)
        { 
         var deviceStatus =_deviceProvider.IsConnected(clientId);
       
            this.Parser.HandlePayload().Subscribe(buffer=>ParserBuffer(buffer));
        }

        public override void DeviceStatusProcess(DeviceStatus status, string clientId, TcpServerProperties tcpServerProperties)
        {
            //throw new NotImplementedException();
        }

        public async Task ParserBuffer(IByteBuffer buffer)
        {
            List<string> result = new List<string>();
            while (buffer.ReadableBytes > 0)
            {
                result.Add(buffer.ReadString(this.Parser.GetNextFixedRecordLength(),
                    Encoding.GetEncoding("gb2312")));
            }

            //  var str= buffer.ReadString(buffer.ReadableBytes, Encoding.GetEncoding("gb2312"));

            var byteBuffer=  Unpooled.Buffer();
            byteBuffer.WriteString("\r\n", Encoding.UTF8); 
            byteBuffer.WriteString("processing complete", Encoding.UTF8);
            await Sender.SendAndFlushAsync(byteBuffer);
            buffer.Release();
            //  await Sender.SendAndFlushAsync("message received",Encoding.UTF8);
            this.Parser.Close(); 
        }

    }
