node_aclをpassport-localで試してみます。コードを実行すると、admin-user'/admin'のルートを確保できず、/loginページにリダイレクトされます。ACL - パスポートと一緒にaclを実装する
私の最小実行可能な例の下に検索：
require('dotenv').config()
const express = require('express')
// const fs = require('fs')
const path = require('path')
const logger = require('morgan')
const bodyParser = require('body-parser')
const cookieParser = require('cookie-parser')
const session = require('express-session')
const passport = require('passport')
const LocalStrategy = require('passport-local').Strategy
const ACL = require('acl')
// load user.json file
// const d = fs.readFileSync(path.join(__dirname, '/../data/user.json'))
// const userObj = JSON.parse(d)
const userObj = [{
id: 1,
username: 'admin',
password: 'admin',
email: '[email protected]',
role: 'admin',
},
{
id: 2,
username: 'user',
password: 'user',
email: '[email protected]',
role: 'user',
},
]
const app = express()
// view engine setup
app.set('views', path.join(__dirname, 'views'))
app.set('view engine', 'pug')
app.use(logger(process.env.LOG_ENV))
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({

app.use(express.static(path.join(__dirname, '/../public')))
app.use(cookieParser())
app.use(session({

resave: false,
saveUninitialized: false,
}))

app.use(passport.initialize())
app.use(passport.session())
function authenticate() {
passport.serializeUser((user, done) => {
done(null, user.id)
})
passport.deserializeUser(async(id, done) => {
// const user = await serviceAuth.findById(id)
const user = userObj.find(item => item.id === id)
done(null, user)
})
// Sign in with username and Password
passport.use('local', new LocalStrategy({
usernameField: 'username',
}, async(username, password, done) => {
const user = userObj.find(item => item.username === username)
done(null, user)
}))
}
const isAuthenticated = (req, res, next) => {
if (req.isAuthenticated()) {
res.locals.user = req.session.user
return next()
}
res.redirect('login')
}
authenticate()

任意の提案は、なぜ、/adminだけadmin userなるルートを呼び出すことはできませんか？
返信いただきありがとうございます。
。いくつかのテストの後に、 'HttpError：リソースにアクセスするためのアクセス権が不十分です'というメッセージが表示されました。ユーザーとしてログインした '/ admin'に返信しました。 – Stamos
