SDK监听节点链码事件

SDK监听节点链码事件

SDK部分代码（通道实例化之前）：

            Map<Long, BlockEvent> blockEvents = Collections.synchronizedMap(new HashMap<>(100));

            String blockListenerHandle = channel.registerBlockListener(blockEvent -> { // register a block listener
                try {
                    //获得区块的区块号
                    final long blockNumber = blockEvent.getBlockNumber();
                    //在事件结果中添加区块号对应的事件
                    blockEvents.put(blockNumber, blockEvent);

                    Iterable<BlockEvent.TransactionEvent> transactionEvents = blockEvent.getTransactionEvents();
                    for (BlockEvent.TransactionEvent event : transactionEvents) {
                        for (BlockInfo.TransactionEnvelopeInfo.TransactionActionInfo info : event.getTransactionActionInfos()) {
                            System.out.println(info.getEvent().getEventName());
                            System.out.println(new String(info.getEvent().getPayload()));
                        }
                    }

                } catch (AssertionError | Exception e) {
                    e.printStackTrace();
                }
            });

链码使用代码：

stub.SetEvent("result", value)
