nodejs測試Hyperledger Composer v0.15失敗，並顯示錯誤：找不到卡：PeerAdmin @ hlfv1

Question

隨着v0.15中卡的實現，使用概要文件的測試例程的早期版本（顯然）將無法工作。 但是，我找不到一種SDK方法來創建運行測試所需的卡。 通過v0.14進行測試的代碼的“之前”部分如下所示，該部分使用嵌入式配置文件，創建網絡的臨時實例並運行測試：

describe('Finance Network', () => {

    // let adminConnection;
    let businessNetworkConnection;

    before(() => {
        BrowserFS.initialize(new BrowserFS.FileSystem.InMemory());
        const adminConnection = new AdminConnection({ fs: bfs_fs });
        return adminConnection.createProfile('defaultProfile', {
            type: 'embedded'
        })
            .then(() => {
                return adminConnection.connect('defaultProfile', adminID, adminPW);
            })
            .then(() => {
                return BusinessNetworkDefinition.fromDirectory(path.resolve(__dirname, '..'));
            })
            .then((businessNetworkDefinition) => {
                return adminConnection.deploy(businessNetworkDefinition);
            })
            .then(() => {
                businessNetworkConnection = new BusinessNetworkConnection({ fs: bfs_fs });
                return businessNetworkConnection.connect('defaultProfile', network, adminID, adminPW);
            });
    });

我試圖在Nodejs文檔中找到（並且尚未發現）的是如何在使用相同方法的同時創建必要的卡來完成這項工作。

我希望將以下代碼行替換為可創建所需卡的內容：

        return adminConnection.createProfile('defaultProfile', {
            type: 'embedded'
        })
            .then(() => {
                return adminConnection.connect('defaultProfile', adminID, adminPW);
            })

我看到卡創建的唯一地方是composer-client Participant Registry，但這是Catch-22的情況，必須連接才能創建卡，但是需要連接卡。 像我們過去對Hyperledger-Composer的眾多發行版所做的那樣，建議編寫基於摩卡的測試的推薦方法是什么？

謝謝！

我想在建立基於卡的API的基礎上需要做一些改進，但是您應該只使用API​​查看類似的內容：

// Embedded connection used for local testing
const connectionProfile = {
    name: 'embedded',
    type: 'embedded'
};
// Embedded connection does not need real credentials
const credentials = {
    certificate: 'FAKE CERTIFICATE',
    privateKey: 'FAKE PRIVATE KEY'
};

// PeerAdmin identity used with the admin connection to deploy business networks
const deployerMetadata = {
    version: 1,
    userName: 'PeerAdmin',
    roles: [ 'PeerAdmin', 'ChannelAdmin' ]
};
const deployerCard = new IdCard(deployerMetadata, connectionProfile);
deployerCard.setCredentials(credentials);

// In-memory card store for testing so cards are not persisted to the file system
const cardStore = new MemoryCardStore();
const adminConnection = new AdminConnection({ cardStore: cardStore });

const deployerCardName = 'PeerAdmin';
const adminUserName = 'admin';
let adminCardName;
let businessNetworkDefinition;

return adminConnection.importCard(deployerCardName, deployerCard).then(() => {
    return adminConnection.connect(deployerCardName);
}).then(() => {
    return BusinessNetworkDefinition.fromDirectory(path.resolve(__dirname, '..'));
}).then(definition => {
    businessNetworkDefinition = definition;
    // Install the Composer runtime for the new business network
    return adminConnection.install(businessNetworkDefinition.getName());
}).then(() => {
    // Start the business network and configure an network admin identity
    const startOptions = {
        networkAdmins: [
            {
                userName: adminUserName,
                enrollmentSecret: adminSecret
            }
        ]
    };
    return adminConnection.start(businessNetworkDefinition, startOptions);
}).then(adminCards => {
    // Import the network admin identity for us to use
    adminCardName = 'admin@' + businessNetworkDefinition.getName();
    return adminConnection.importCard(adminCardName, adminCards.get(adminUserName));
}).then(() => {
    // Connect to the business network using the network admin identity
    businessNetworkConnection = new BusinessNetworkConnection({ cardStore: cardStore });
    return businessNetworkConnection.connect(adminCardName);
});

需要說明的是，從AdminConnection.start()調用返回的網絡管理卡正在（按我的鍵入）正在添加到此問題中： hyperledger / composer＃2753

CLI命令已經注冊了網絡管理員身份並為該管理員輸出了一個卡，如果您要使用它而不是交給其他人，則可以導入該卡。

經過幾天的試驗，我找到了解決此問題的方法。 以下代碼序列使用在v0.15版本中創建的PeerAdmin卡。 我導入該卡，並在adminConnect之后，更新卡的元數據中的businessNetwork元素，然后，在重新導入卡之后，部署並連接到業務網絡。

describe('Finance Network', function () {
    this.timeout(_timeout);
    let businessNetworkConnection;
    let peerName = 'PeerAdmin@hlfv1';
    before(function () {
        const adminConnection = new AdminConnection();
        let idPeer;
        return hlc_idCard.fromDirectory(_home+'/.composer/cards/'+peerName)
        .then ((_idPeer) => {
            idPeer = _idPeer;
            return adminConnection.importCard(peerName, idPeer);
        })
        .then(() => {
            return adminConnection.connect(peerName);
        })
        .then(() => {
            return BusinessNetworkDefinition.fromDirectory(path.resolve(__dirname, '..'));
        })
        .then((businessNetworkDefinition) => {
            idPeer.metadata.businessNetwork = network;
            return adminConnection.importCard(peerName, idPeer)
            .then(() => {
                return adminConnection.deploy(businessNetworkDefinition,{'card': idPeer});
            });
        })
        .then(() => {
            businessNetworkConnection = new BusinessNetworkConnection();
            return businessNetworkConnection.connect(peerName);
        });
    });
