示例1: Promise
return new Promise((resolve, reject) => {
// get a new ChannelEventHub when registering a listener
// with startBlock or endBlock when doing a replay
// The ChannelEventHub must not have been connected or have other
// listeners.
let channel_event_hub: ChannelEventHub = channel.newChannelEventHub('peer0.org1.example.com');
let handle = setTimeout(() => {
t.fail('Timeout - Failed to receive replay the event for event1');
channel_event_hub.unregisterTxEvent(query_tx_id);
channel_event_hub.disconnect(); //shutdown down since we are done
}, 10000);
channel_event_hub.registerTxEvent(query_tx_id, (txnid, code, block_num) => {
clearTimeout(handle);
t.pass('Event has been replayed with transaction code:' + code + ' for transaction id:' + txnid + ' for block_num:' + block_num);
resolve('Got the replayed transaction');
}, (error) => {
clearTimeout(handle);
t.fail('Failed to receive event replay for Event for transaction id ::' + query_tx_id);
throw (error);
},
// a real application would have remembered the last block number
// received and used that value to start the replay
// Setting the disconnect to true as we do not want to use this
// ChannelEventHub after the event we are looking for comes in
{ startBlock: 0, disconnect: true }
);
t.pass('Successfully registered transaction replay for ' + query_tx_id);
channel_event_hub.connect(); //connect to receive filtered blocks
t.pass('Successfully called connect on the transaction replay event hub for filtered blocks');
