基於RXNetty client給server 發消息 獲取回調方法

代碼如下

 for (;;) {
            byte[] replyBytes = client.connect()
                    .flatMap(new Func1<ObservableConnection<byte[], byte[]>, Observable<byte[]>>() {
                        @Override
                        public Observable<byte[]> call(final ObservableConnection<byte[], byte[]> connection) {
                            connection.writeBytesAndFlush(frame.getDownwardBytes());
                            return connection.getInput();
                        }
                    })
                    .timeout(1, TimeUnit.SECONDS) // 等待一秒
                    .retry(3) // 超時後重試3次
                    .onErrorReturn(new Func1<Throwable, byte[]>() {
                        @Override
                        public byte[] call(Throwable throwable) {
                            logger.error("{}", throwable);
                            return null;
                        }
                    }) // 3次後仍然失敗則返回null
                    .take(1)
                    .toBlocking()
                    .first();

            if (replyBytes != null) {
         <span style="white-space:pre">	</span>//獲取數據

            } else {
               
            }
        }
