前言
sdkを使用してchaincodeをインストールする場合は、次のパラメータを指定する必要があります.
github.com/example_ccであり、システムはgopathのパスの下のsrcディレクトリの中のgithub.com/example_ccの下のchaincodeファイルをロードする.gopathの動作を設定し、具体的なインプリメンテーションで説明する.ルート
app.js // peer chaincode
app.post('/chaincodes', function(req, res) {
//1
logger.debug('==================== INSTALL CHAINCODE ==================');
var peers = req.body.peers;
var chaincodeName = req.body.chaincodeName;
var chaincodePath = req.body.chaincodePath;
var chaincodeVersion = req.body.chaincodeVersion;
// chaincode peer
logger.debug('peers : ' + peers); // target peers list
// chaincode
logger.debug('chaincodeName : ' + chaincodeName);
//chaincode
logger.debug('chaincodePath : ' + chaincodePath);
//chaincode
logger.debug('chaincodeVersion : ' + chaincodeVersion);
if (!peers || peers.length == 0) {
res.json(getErrorMessage('\'peers\''));
return;
}
if (!chaincodeName) {
res.json(getErrorMessage('\'chaincodeName\''));
return;
}
if (!chaincodePath) {
res.json(getErrorMessage('\'chaincodePath\''));
return;
}
if (!chaincodeVersion) {
res.json(getErrorMessage('\'chaincodeVersion\''));
return;
}
// 2 install-chaincode.js
install.installChaincode(peers, chaincodeName, chaincodePath, chaincodeVersion, req.username, req.orgname)
.then(function(message) {
res.send(message);
});
});このルートは2つのことしかしていません
installChaincode方法を呼び出す.具体的な実装
install-chaincode.js var path = require('path');
var fs = require('fs');
var util = require('util');
var config = require('../config.json');
var helper = require('./helper.js');
var logger = helper.getLogger('install-chaincode');
var tx_id = null;
var installChaincode = function(peers, chaincodeName, chaincodePath,
chaincodeVersion, username, org) {
logger.debug(
'
============ Install chaincode on organizations ============
');
// gopath balance-transfer/artifacts/ chaincode
helper.setupChaincodeDeploy();
var channel = helper.getChannelForOrg(org);
var client = helper.getClientForOrg(org);
//1 admin
return helper.getOrgAdmin(org).then((user) => {
//2 request
var request = {
targets: helper.newPeers(peers, org), // peer rpc
chaincodePath: chaincodePath,
chaincodeId: chaincodeName,
chaincodeVersion: chaincodeVersion
};
//3 ， chaincode
return client.installChaincode(request);
}, (err) => {
logger.error('Failed to enroll user \'' + username + '\'. ' + err);
throw new Error('Failed to enroll user \'' + username + '\'. ' + err);
}).then((results) => {
var proposalResponses = results[0];
var proposal = results[1];
var all_good = true;
// 4
for (var i in proposalResponses) {
let one_good = false;
if (proposalResponses && proposalResponses[i].response &&
proposalResponses[i].response.status === 200) {
one_good = true;
logger.info('install proposal was good');
} else {
logger.error('install proposal was bad');
}
all_good = all_good & one_good;
}
//
if (all_good) {
logger.info(util.format(
'Successfully sent install Proposal and received ProposalResponse: Status - %s',
proposalResponses[0].response.status));
logger.debug('
Successfully Installed chaincode on organization ' + org +
'
');
return 'Successfully Installed chaincode on organization ' + org;
} else {
logger.error(
'Failed to send install Proposal or receive valid response. Response null or status is not 200. exiting...'
);
return 'Failed to send install Proposal or receive valid response. Response null or status is not 200. exiting...';
}
}, (err) => {
logger.error('Failed to send install proposal due to error: ' + err.stack ?
err.stack : err);
throw new Error('Failed to send install proposal due to error: ' + err.stack ?
err.stack : err);
});
};
exports.installChaincode = installChaincode;
