无法使用Hyperledger Composer Javascript API发行身份证 [英] Unable to issue identity card using Hyperledger Composer Javascript API

问题描述

我正在尝试使用Hyperledger Composer的javascript API创建身份证.这是代码:

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();

我已经有一个参与者testUser. 尽管代码成功，并且我获得了userID和userSecret，但没有创建卡.
有谁知道如何做到这一点，而不是使用cli?

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?

推荐答案

您尚未导入卡.

例如

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);
    }

导入后，应连接卡以将证书/密钥下载到钱包，例如await businessNetworkConnection.connect(cardName);

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