node.js - 为 IBM Block chain Hyperledger Fabric 运行enrollAdmin.js 时遇到错误

Question

我正在遵循 GitHub 上的教程，使用 IBM Blockchain（hyperledger 结构，我按照此处的步骤进行云部署：https ://github.com/IBM/evote 唯一的变化是我使用了 Hyperledger 结构 v2。 2、node.js v 15.4.0 在第 6 步“运行应用程序”中，当我尝试运行 nodeenrollAdmin.js 命令时收到错误消息。我在终端中收到的错误消息如下：

2021-04-22T08:57:53.453Z - error: [FabricCAClientService.js]: Failed to enroll app-admin, error:%o message=Calling enroll endpoint failed, CONNECTION Timeout, stack=Error: Calling enroll endpoint failed, CONNECTION Timeout

Failed to enroll admin user ' + app-admin + : Error: Calling enroll endpoint failed, CONNECTION Timeout

enrollAdmin.js 文件如下

'use strict';

const FabricCAServices = require('fabric-ca-client');
const { FileSystemWallet, X509WalletMixin } = require('fabric-network');
const fs = require('fs');
const path = require('path');

// capture network variables from config.json
const configPath = path.join(process.cwd(), './config.json');
const configJSON = fs.readFileSync(configPath, 'utf8');

async function main() {
  try {

    // Create a new CA client for interacting with the CA.
    const caURL = caName;
    const ca = new FabricCAServices(caURL);

    // Create a new file system based wallet for managing identities.
    const walletPath = path.join(process.cwd(), 'wallet');
    const wallet = new FileSystemWallet(walletPath);
    console.log(`Wallet path: ${walletPath}`);

    // Check to see if we've already enrolled the admin user.
    const adminExists = await wallet.exists(appAdmin);
    if (adminExists) {
      console.log('An identity for the admin user "admin" already exists in the wallet');
      return;
    }

    // Enroll the admin user, and import the new identity into the wallet.
    const enrollment = await ca.enroll({ enrollmentID: appAdmin, enrollmentSecret: appAdminSecret });
    const identity = X509WalletMixin.createIdentity(orgMSPID, enrollment.certificate, enrollment.key.toBytes());
    wallet.import(appAdmin, identity);
    console.log('msg: Successfully enrolled admin user ' + appAdmin + ' and imported it into the wallet');

  } catch (error) {
    console.error(`Failed to enroll admin user ' + ${appAdmin} + : ${error}`);
    process.exit(1);
  }
}

main();
