路由

app.js

//根据交易id  查询交易详情 Query Get Transaction by Transaction ID
app.get('/channels/:channelName/transactions/:trxnId', function(req, res) {
logger.debug(
'================ GET TRANSACTION BY TRANSACTION_ID ======================'
);
logger.debug('channelName : ' + req.params.channelName);
let trxnId = req.params.trxnId;
let peer = req.query.peer;
if (!trxnId) {
res.json(getErrorMessage('\'trxnId\''));
return;
}
// 具体实现
query.getTransactionByID(peer, trxnId, req.username, req.orgname)
.then(function(message) {
res.send(message);
});
});

具体实现

query.js

var getTransactionByID = function(peer, trxnID, username, org) {
//1  peer节点地址
var target = buildTarget(peer, org);
//2 获取channel
var channel = helper.getChannelForOrg(org);
//3 获取注册用户
return helper.getRegisteredUsers(username, org).then((member) => {
//4 查询交易详情
return channel.queryTransaction(trxnID, target);
}, (err) => {
logger.info('Failed to get submitter "' + username + '"');
return 'Failed to get submitter "' + username + '". Error: ' + err.stack ?
err.stack : err;
}).then((response_payloads) => {
//5 处理响应
if (response_payloads) {
logger.debug(response_payloads);
return response_payloads;
} else {
logger.error('response_payloads is null');
return 'response_payloads is null';
}
}, (err) => {
logger.error('Failed to send query due to error: ' + err.stack ? err.stack :
err);
return 'Failed to send query due to error: ' + err.stack ? err.stack : err;
}).catch((err) => {
logger.error('Failed to query with error:' + err.stack ? err.stack : err);
return 'Failed to query with error:' + err.stack ? err.stack : err;
});
};
