前言

根据块号查询区块信息。需要如下参数：

  • 哪个channel
  • 哪个peer节点
  • 第几个区块

示例中展示的是org1组织下的peer1节点上第一个区块的信息。

路由

app.js

//查询区块信息  Query Get Block by BlockNumber
app.get('/channels/:channelName/blocks/:blockId', function(req, res) {
    logger.debug('==================== GET BLOCK BY NUMBER ==================');
    let blockId = req.params.blockId;
    let peer = req.query.peer;
    logger.debug('channelName : ' + req.params.channelName);
    logger.debug('BlockID : ' + blockId);
    logger.debug('Peer : ' + peer);
    if (!blockId) {
        res.json(getErrorMessage('\'blockId\''));
        return;
    }
    // 具体实现
    query.getBlockByNumber(peer, blockId, req.username, req.orgname)
        .then(function(message) {
            res.send(message);
        });
});

具体实现

这个实现很简单，关键就是channel.queryBlock(parseInt(blockNumber), target)。

query.js

var getBlockByNumber = function(peer, blockNumber, username, org) {
    //1 节点地址
    var target = buildTarget(peer, org);
    //2 channel 
    var channel = helper.getChannelForOrg(org);
    //3  获取当前注册用户
    return helper.getRegisteredUsers(username, org).then((member) => {
        //4 查询区块信息
        return channel.queryBlock(parseInt(blockNumber), 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 处理结果
        if (response_payloads) {
            //logger.debug(response_payloads);
            logger.debug(response_payloads);
            return response_payloads; //response_payloads.data.data[0].buffer;
        } 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;
    });
};

基本流程

Created with Raphaël 2.1.2 Start 获取到当前用户 通过channel查询区块信息 处理结果 End

API访问

echo "GET query Block by blockNumber"
echo
curl -s -X GET \
  "http://localhost:4000/channels/mychannel/blocks/1?peer=peer1" \
  -H "authorization: Bearer $ORG1_TOKEN" \
  -H "content-type: application/json"
echo
echo

控制台打印：


GET query Block by blockNumber
