nodejs测试超级分类系统编写器v0.15失败，错误:卡未找到: PeerAdmin@hlfv1 1

Question

通过在v0.15中实现卡片，使用概要文件(显然)的测试例程的早期版本将无法工作。但是，我找不到SDK方法来创建运行测试所需的卡片。从v0.14到我的测试的代码前部分如下所示，它使用了嵌入式配置文件，创建了网络的临时实例并运行测试：

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);
            });
    });

我试图在nodejs文档中找到(而且尚未找到)的是如何创建必要的卡片来完成这项工作，同时使用同样的方法。

我希望将以下代码行替换为创建必要卡片的代码：

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

我看到卡片创建的唯一地方是在作曲家-客户参与注册，但这是一个陷阱-22的情况下，我必须连接创建卡，但我需要一张卡来连接。我们建议编写基于摩卡的测试的方法是什么，就像我们过去对Hyperledger-Composer的无数版本所做的那样？

谢谢!

经过几天的实验，我找到了解决这个问题的方法。下面的代码序列使用作为v0.15发行版一部分创建的PeerAdmin卡。我导入该卡，在adminConnect之后，更新卡元数据中的businessNetwork元素，然后在重新导入卡之后，部署并连接到业务网络。

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);
        });
    });

我想，在建立基于卡的API时，可能需要进行一些改进，但是您应该只使用API来查看这样的内容：

// 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);
});

要注意的是，从调用AdminConnection.start()返回的网络管理卡(如我所键入的)正在添加到这个问题中：超级分类账/作曲家#2753。

CLI命令已经注册了网络管理标识，并为这个管理员输出了一张卡，如果您想要使用它，而不是给其他人，就可以导入它。
