基于RXNetty client给server 发消息 获取回调方法

代码如下

 for (;;) {
            byte[] replyBytes = client.connect()
                    .flatMap(new Func1, Observable>() {
                        @Override
                        public Observable call(final ObservableConnection connection) {
                            connection.writeBytesAndFlush(frame.getDownwardBytes());
                            return connection.getInput();
                        }
                    })
                    .timeout(1, TimeUnit.SECONDS) // 等待一秒
                    .retry(3) // 超时后重试3次
                    .onErrorReturn(new Func1() {
                        @Override
                        public byte[] call(Throwable throwable) {
                            logger.error("{}", throwable);
                            return null;
                        }
                    }) // 3次后仍然失败则返回null
                    .take(1)
                    .toBlocking()
                    .first();

            if (replyBytes != null) {
         	//获取数据

            } else {
               
            }
        }
