hyperledger-fabric - 无法调用链码名称 :"lscc"，错误 : container exited with 1: chaincode registration failed (Fabric 1. 4.1)

Question

我正在尝试创建一个单一的组织、单一的 ca、单一的对等网络，由 nodejs-sdk 引导。 .我用过 this sample以供引用。

当我尝试 instantiate()我在 docker logs ax-peer 访问的对等方中收到此错误的链码

订购者没有注册额外的日志。我的代码如下

const createClientInstance = async () => {
  let myClient = new client();
  const ordererConfig = {
    hostname: 'orderer0',
    url: 'grpc://localhost:7050',
    pem: readCryptoFile('ordererOrg.pem')
  };
  const orderer = myClient.newOrderer(ordererConfig.url, {
    pem: ordererConfig.pem,
    'ssl-target-name-override': ordererConfig.hostname
  });

  let peerConfig = {
    hostname: 'ax-peer',
    url: 'grpc://localhost:7051',
    eventHubUrl: 'grpc://localhost:7053',
    pem: readCryptoFile('axOrg.pem')
  };
  const defaultPeer = myClient.newPeer(peerConfig.url, {
    pem: peerConfig.pem,
    'ssl-target-name-override': peerConfig.hostname
  });
  myClient.setStateStore(await client.newDefaultKeyValueStore({
    path: './ax-peer'
  }))

  let user = await myClient.getUserContext('admin', true);
  if (user && user.isEnrolled()) {
    console.log('Existing admin user used');

  } else {
    let url = 'http://localhost:7054'
    const ca = new CAClient(url, {
      verify: false
    });

    let enrollmentID = 'admin';
    let enrollmentSecret = 'adminpw';
    const enrollment = await ca.enroll({
      enrollmentID: 'admin',
      enrollmentSecret: 'adminpw'
    });
    user = new User(enrollmentID, myClient);
    await user.setEnrollment(enrollment.key, enrollment.certificate, 'AxOrgMSP');
  };
  await myClient.setUserContext(user);

  let adminUser = await myClient.createUser({
    username: `Admin@ax-peer`,
    mspid: 'AxOrgMSP',
    cryptoContent: {
      privateKeyPEM: readCryptoFile('Admin@ax-org-key.pem'),
      signedCertPEM: readCryptoFile('Admin@ax-org-cert.pem')
    }
  });
  let channelRes = await myClient.queryChannels(defaultPeer);

  // Create a new channel. Does not make you join it though
  let txId = myClient.newTransactionID();
  let envelope_bytes = fs.readFileSync('./channel.tx');
  var channelConfig = myClient.extractChannelConfig(envelope_bytes);
  let signature = myClient.signChannelConfig(channelConfig);
  const request = {
      name: 'default',
      orderer: orderer,
      config: channelConfig,
      signatures: [signature],
      txId: txId
    };

    await myClient.createChannel(request);
    let channel = myClient.newChannel('default');
    channel.addOrderer(orderer);
    channel.addPeer(defaultPeer);
    const genesisBlock = await channel.getGenesisBlock({ txId: myClient.newTransactionID() });
    let res = await channel.joinChannel({
        targets: [defaultPeer],
        txId: myClient.newTransactionID(),
        block: genesisBlock
      }, 120000);

    const installReq = {
      targets: [ defaultPeer ],
      chaincodePath: ccPath,
      chaincodeId:'ax-chaincode',
      chaincodeVersion: 'v2',
      chaincodeType: 'node'
    };
    let installRes = await myClient.installChaincode(installReq, 120000);

    let instantiateResponse = await channel.sendInstantiateProposal({
      targets: [ defaultPeer ],
      chaincodeId: 'ax-chaincode',
      chaincodeVersion: 'v2',
      chaincodeType: 'node',
      txId: myClient.newTransactionID()
    });

    // This fails
    console.log(instantiateResponse);
};

由于语言是 node我必须提供链码的绝对路径。我的文件夹结构是

- chaincode
  - src
    - ax-chaincode
      - package.json
      - index.js (fabric-contract-api used)
- server
  - index.js (where I am calling the above code)

如果我运行 client.queryInstalledChaincodes(defaultPeer)然后它返回这个日志，所以我猜链码正在被安装。

{ chaincodes: 
   [ { name: 'ax-chaincode',
       version: 'v2',
       path: '/home/varun/Algorythmix/Core-Projects/ax-boilerplate/chaincode/src/ax-chaincode',
       input: '',
       escc: '',
       vscc: '',
       id: [Object] } ] }

我该如何解决？我要坚持使用 nodejs并且不要将我的链码更改为 golang .该示例还提取证书并将其存储在根文件夹中，以便无需执行 docker exec -it bash 即可访问它。 .

Answer 1

因此，根据 Gari 的建议，我在 peer-base.yaml 中添加了该命令。文件。代码仍然无效，但在 docker logs ax-peer一个更具描述性的错误弹出，说 fabric-chaincode-node未找到。经检查，似乎除了安装 fabric-contract-api ，我还要安装fabric-shim在链码文件夹中。这是作为 per this document 在最新 Fabric 中作为要求添加的.

自 fabric-contract-api扩展 fabric-shim所以我没有包括它，现在我已经安装了链码。

编辑 - 2020

nodejs SDK 的文档已经转移。 fabric-contract-api 的发行说明和新依赖项可以找到 at this link其中说明 fabric-shim现在是 fabric-shim-api
