前言
上一篇文章我们已经启动了fabric网络/node服务，这篇文章主要来详细分析用户注册的过程。
具体实现
找到app.js中关于users的路由：
//注册用户
app.post('/users', function(req, res) {
// 1 参数校验
var username = req.body.username;
var orgName = req.body.orgName;
logger.debug('End point : /users');
logger.debug('User name : ' + username);
logger.debug('Org name : ' + orgName);
if (!username) {
res.json(getErrorMessage('\'username\''));
return;
}
if (!orgName) {
res.json(getErrorMessage('\'orgName\''));
return;
}
// 2 生成jwt 添加用户名以及组织信息
var token = jwt.sign({
exp: Math.floor(Date.now() / 1000) + parseInt(hfc.getConfigSetting('jwt_expiretime')),
username: username,
orgName: orgName
}, app.get('secret'));
// 3 注册用户 如果成功连同jwt一起返回
helper.getRegisteredUsers(username, orgName, true).then(function(response) {
if (response && typeof response !== 'string') {
response.token = token;
res.json(response);
} else {
res.json({
success: false,
message: response
});
}
});
});
从上面得知要看具体实现，还需要进入helper.js中查看getRegisteredUsers（）：
var getRegisteredUsers = function(username, userOrg, isJson) {
var member;
var client = getClientForOrg(userOrg);
var enrollmentSecret = null;
// 设置公私钥存储的地方
return hfc.newDefaultKeyValueStore({
// 这里只要求path参数 来作为存储的地方
path: getKeyStoreForOrg(getOrgName(userOrg))
}).then((store) => {
// 设置状态持久化存储（如（证书，私钥。。））
client.setStateStore(store);
// clearing the user context before switching
client._userContext = null;
//1 获取用户信息 （从 内存-->statestore 依次查找）
return client.getUserContext(username, true).then((user) => {
if (user && user.isEnrolled()) {
// 从持久化中 成功加载此 user
logger.info('Successfully loaded member from persistence');
return user;
} else {
let caClient = caClients[userOrg];
//2 获得adminuser 来注册账户
return getAdminUser(userOrg).then(function(adminUserObj) {
member = adminUserObj;
return caClient.register({
enrollmentID: username,
// 与此用户关联的隶属关系
affiliation: userOrg + '.department1'
}, member); // 注册员
}).then((secret) => {
enrollmentSecret = secret;
logger.debug(username + ' registered successfully');
//3 注册成功后 拿着secret 来enroll
return caClient.enroll({
enrollmentID: username,
enrollmentSecret: secret
});
}, (err) => {
logger.debug(username + ' failed to register');
return '' + err;
//return 'Failed to register '+username+'. Error: ' + err.stack ? err.stack : err;
}).then((message) => { // enroll 返回的信息
if (message && typeof message === 'string' && message.includes(
'Error:')) {
logger.error(username + ' enrollment failed');
return message;
}
logger.debug(username + ' enrolled successfully');
// 构建user对象
member = new User(username);
member._enrollmentSecret = enrollmentSecret;
//4 设置此User实例的注册对象 来持久化在client中
return member.setEnrollment(message.key, message.certificate, getMspID(userOrg));
}).then(() => {
//5 保存用户的上下文环境（e.g 证书 私钥 ） 用户签名 各种请求
client.setUserContext(member);
return member;
}, (err) => {
logger.error(util.format('%s enroll failed: %s', username, err.stack ? err.stack : err));
return '' + err;
});;
}
});
}).then((user) => {
// 6 返回用户信息
if (isJson && isJson === true) {
var response = {
success: true,
secret: user._enrollmentSecret,
message: username + ' enrolled Successfully',
};
return response;
}
return user;
}, (err) => {
logger.error(util.format('Failed to get registered user: %s, error: %s', username, err.stack ? err.stack : err));
return '' + err;
});
};
基本流程 ：
API访问
为org1组织建立一个用户名为Jim的用户。在命令行里输入：
echo "POST request Enroll on Org1 ..."
echo
ORG1_TOKEN=$(curl -s -X POST \
http://localhost:4000/users \
-H "content-type: application/x-www-form-urlencoded" \
-d 'username=Jim&orgName=org1')
echo $ORG1_TOKEN
控制面板打印结果：
POST request Enroll on Org1 ...
{"success":true,"secret":"xDfluXIPURbu","message":"Jim enrolled Successfully","token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1MDgxNTkyMjQsInVzZXJuYW1lIjoiSmltIiwib3JnTmFtZSI6Im9yZzEiLCJpYXQiOjE1MDgxMjMyMjR9.rE5UuViSzmDcdHNZRXt22izpopY5eVkJ7YbfXILjSQk"}
ORG1 token is eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE1MDgxNTkyMjQsInVzZXJuYW1lIjoiSmltIiwib3JnTmFtZSI6Im9yZzEiLCJpYXQiOjE1MDgxMjMyMjR9.rE5UuViSzmDcdHNZRXt22izpopY5eVkJ7YbfXILjSQk
// 上面的token是 访问后面API的必要参数
可以看出 Jim已经成功被注册了，其公私钥存放在/tmp/fabric-client-kvs_peerOrg1中(可在config.json中自定义keyValueStore路径)：
