前言

取引idに基づいて取引詳細を照会します.次のパラメータが必要です.

取引id

peerノード

channel

6番目の記事の取引id eb058850e7247ad0bc25ec57ced1cd1255666c390ca0c9300858ce6e57175221を多重化することができます.

ルート

指定したpeerおよびトランザクションidを受信し、パラメータを検証して特定の実装に転送します.app.js

// id    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;
    }
    //  
    query.getTransactionByID(peer, trxnId, req.username, req.orgname)
        .then(function(message) {
            res.send(message);
        });
});

具体的な実装

query.js

var getTransactionByID = function(peer, trxnID, username, org) {
    //1  peer 
    var target = buildTarget(peer, org);
    //2  channel
    var channel = helper.getChannelForOrg(org);
    //3  
    return helper.getRegisteredUsers(username, org).then((member) => {
        //4  
        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  
        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;
    });
};
