node.js - Nodejs 测试 Hyperledger Composer v0.15 失败，错误为 : Card not found: PeerAdmin@hlfv1

Question

随着 v0.15 中卡的实现，使用配置文件的先前版本的测试例程(显然)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。我的测试中从 v0.14 开始的代码“之前”部分如下所示，它使用嵌入式配置文件，创建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 Node.js 文档中找到(尚未找到)的是如何创建必要的卡片来完成这项工作，同时使用相同的方法。

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);
            })

我看到卡创建的唯一地方是在 Composer 客户端参与者注册表中，但这是第 22 条军规的情况，我必须连接才能创建卡，但我需要一张卡才能连接。正如我们在过去无数个 Hyperledger-Composer 版本中所做的那样，推荐的编写基于 mocha 的测试的方法是什么？

谢谢!

我认为，随着基于卡的 API 的建立，可能需要进行一些改进，但您应该仅使用 API 来查看类似的内容:

// 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);
});

需要注意的是，从调用 AdminConnection.start() 返回的网络管理卡(正如我所输入的)正在添加到此问题中:hyperledger/composer#2753

CLI 命令已注册网络管理员身份并为此管理员输出一张卡，如果您想使用它而不是将其交给其他人，则可以导入该卡。
