Unable to issue identity card using Hyperledger Co

问题:

I am trying to create an identity card using the javascript API of Hyperledger Composer. Here is the code:

const BusinessNetworkConnection = require('composer- 
client').BusinessNetworkConnection;

async function identityIssue() {
  let businessNetworkConnection = new BusinessNetworkConnection();
  try {
    await businessNetworkConnection.connect('admin@demoNetwork');
    let result = await businessNetworkConnection.issueIdentity('org.acme.demoNetwork.Participant#testUser', 'test');
    console.log(`userID = ${result.userID}`);
    console.log(`userSecret = ${result.userSecret}`);
    await businessNetworkConnection.disconnect();
  } catch(error) {
    console.log(error);
    process.exit(1);
  }
}

identityIssue();

I already have a participant testUser. Although the code succeeds and I get the userID and userSecret, no card is created.
Does anyone have an idea how to do it instead of using the cli?

You haven't imported the card.

eg,

async function importCardForIdentity(cardName, identity) {
        const metadata = {
            userName: identity.userID,
            version: 1,
            enrollmentSecret: identity.userSecret,
            businessNetwork: businessNetworkName
        };
        const card = new IdCard(metadata, connectionProfile);
        await adminConnection.importCard(cardName, card);
    }

See also nodejs test hyperledger composer v0.15 fails with Error: Card not found: PeerAdmin@hlfv1 (answer) it has an example too.

After importing, you should connect with your card to download the cert/key to the wallet eg await businessNetworkConnection.connect(cardName);
