sockets - 使用 Socket Java NIO 连接到 gRPC 服务器，但服务器没有响应

Question

我的 gRPC Java 客户端使用套接字连接到服务器 Java NIO，并且 NIO 将请求的客户端传输到服务器 gRPC 但服务器没有响应。

我的客户端 gRPC 代码：

        private final  ManagedChannel channel;
        private final  MyServiceProviderGrpc.MyServiceProviderBlockingStub blockingStub;
        private final  MyServiceProviderGrpc.MyServiceProviderStub asyncStub;

        public ClientGrpc(String host, int port) 
        {
            this(ManagedChannelBuilder.forAddress(host, port).usePlaintext(true));
        }
        ClientGrpc(ManagedChannelBuilder<?> channelBuilder) 
        {
            channel = channelBuilder.build();
            blockingStub = MyServiceProviderGrpc.newBlockingStub(channel);
            asyncStub = MyServiceProviderGrpc.newStub(channel);         }

        public void greet(String name)          {
            logger.info("Will try to greet " + name + " ...");
            TemperatureRequest request = TemperatureRequest.newBuilder().setQuestion(name).build();
            TemperatureResponse response;
            try 
            {
              response = blockingStub.getTemperature(request);
            } catch (StatusRuntimeException e) 
            {
              logger.info("RPC failed: {0}"+ e.getStatus());
              return;
            }
            logger.info("Greeting: " + response.getAnswer());       }


ClientGrpc clients = new ClientGrpc("localhost",4321);
clients.greet("bap");

我在 NIO 中收到一条消息：
