Admin enrollment Node.js program enrollAdmin.js
enrolls an user "admin" to ca.example.com.
1. View the enrollAdmin.js source code:
$ cp ~/hyperledger-binaries/fabric-samples/fabcar/javascript $ more enrollAdmin.js /* * SPDX-License-Identifier: Apache-2.0 */ 'use strict'; const FabricCAServices = require('fabric-ca-client'); const { FileSystemWallet, X509WalletMixin } = require('fabric-network'); const fs = require('fs'); const path = require('path'); const ccpPath = path.resolve(__dirname, '..', '..', 'basic-network', 'connection.json'); const ccpJSON = fs.readFileSync(ccpPath, 'utf8'); const ccp = JSON.parse(ccpJSON); async function main() { try { // Create a new CA client for interacting with the CA. const caURL = ccp.certificateAuthorities['ca.example.com'].url; 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('admin'); 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: 'admin', enrollmentSecret: 'adminpw' }); const identity = X509WalletMixin.createIdentity('Org1MSP', enrollment.certificate, enrollment.key.toBytes()); wallet.import('admin', identity); console.log('Successfully enrolled admin user "admin" and imported it into the wallet'); } catch (error) { console.error(`Failed to enroll admin user "admin": ${error}`); process.exit(1); } } main();
As you can see, the script enrolls a user ID with a secret password with ca.example.com. Then it receives the public certificate and the private key from ca.example.com and save them in a directory call wallet.
2. Run it:
$ node enrollAdmin Wallet path: /home/fyicenter/hyperledger-binaries/fabric-samples/fabcar/javascript/wallet Successfully enrolled admin user "admin" and imported it into the wallet $ ls -l wallet/admin/ -rw-rw-r-- 1 fyicenter 246 Apr 1 01:40 2844345e545c1957df94a6362cedabc81682...-priv -rw-rw-r-- 1 fyicenter 182 Apr 1 01:40 2844345e545c1957df94a6362cedabc81682...-pub -rw-rw-r-- 1 fyicenter 986 Apr 1 01:40 admin
