这一步骤介绍register & reroll 一个user的过程， 这一部需要使用上一步注册的admin用户登录， 然后注册一个普通的user， user 的role指定为client. 全部代码如下：

var Fabric_Client = require('fabric-client');
var Fabric_CA_Client = require('fabric-ca-client');
var path = require('path');
var util = require('util');
var os = require('os');
//
var fabric_client = new Fabric_Client();
var fabric_ca_client = null;
var admin_user = null;
var member_user = null;
var store_path = path.join(__dirname, 'hfc-key-store');
console.log(' Store path:'+store_path);
// create the key value store as defined in the fabric-client/config/default.json 'key-value-store' setting
Fabric_Client.newDefaultKeyValueStore({ path: store_path
}).then((state_store) => {
// assign the store to the fabric client
fabric_client.setStateStore(state_store);
var crypto_suite = Fabric_Client.newCryptoSuite();
// use the same location for the state store (where the users' certificate are kept)
// and the crypto store (where the users' keys are kept)
var crypto_store = Fabric_Client.newCryptoKeyStore({path: store_path});
crypto_suite.setCryptoKeyStore(crypto_store);
fabric_client.setCryptoSuite(crypto_suite);
var tlsOptions = {
trustedRoots: [],
verify: false
};
// be sure to change the http to https when the CA is running TLS enabled
fabric_ca_client = new Fabric_CA_Client('http://localhost:7054', null , '', crypto_suite);
// first check to see if the admin is already enrolled
return fabric_client.getUserContext('admin', true);
}).then((user_from_store) => {
if (user_from_store && user_from_store.isEnrolled()) {
console.log('Successfully loaded admin from persistence');
admin_user = user_from_store;
} else {
throw new Error('Failed to get admin.... run enrollAdmin.js');
}
// at this point we should have the admin user
// first need to register the user with the CA server
return fabric_ca_client.register({enrollmentID: 'user1', affiliation: 'org1.department1',role: 'client'}, admin_user);
}).then((secret) => {
// next we need to enroll the user with CA server
console.log('Successfully registered user1 - secret:'+ secret);
return fabric_ca_client.enroll({enrollmentID: 'user1', enrollmentSecret: secret});
}).then((enrollment) => {
console.log('Successfully enrolled member user "user1" ');
return fabric_client.createUser(
{username: 'user1',
mspid: 'Org1MSP',
cryptoContent: { privateKeyPEM: enrollment.key.toBytes(), signedCertPEM: enrollment.certificate }
});
}).then((user) => {
member_user = user;
return fabric_client.setUserContext(member_user);
}).then(()=>{
console.log('User1 was successfully registered and enrolled and is ready to interact with the fabric network');
}).catch((err) => {
console.error('Failed to register: ' + err);
if(err.toString().indexOf('Authorization') > -1) {
console.error('Authorization failures may be caused by having admin credentials from a previous CA instance.\n' +
'Try again after deleting the contents of the store directory '+store_path);
}
