如何在登录和重定向时验证用户和管理员的角色-MEAN Stack

如何解决如何在登录和重定向时验证用户和管理员的角色-MEAN Stack

我一直在尝试验证令牌中用户的角色，并且还在登录时将管理员重定向到管理员的仪表板。对于用户验证和令牌生成，它可以完美工作，但是角色授权目前是头疼的事。

这些是我的路线：

attributeChangedCallback

这是我的用户控制器

const router = express.Router();

const ctrlUser = require('../controllers/user.controller');
const ctrlMember = require('../controllers/member.controller');

const jwtHelper = require('../config/jwtHelper');


// General Registration and Authentication
router.post('/register',ctrlUser.register);
router.post('/authenticate',ctrlUser.authenticate);

//If User Role Is Equal To Admin then.......
router.get('/admin');

// Member => localhost:3000/api/.......
router.get('/user/members',ctrlMember.get);
router.post('/user/members/register',ctrlMember.register);
router.get('/user/members/:id',ctrlMember.getID);
router.put('/user/members/:id',ctrlMember.put);
router.delete('/user/members/:id',ctrlMember.delete);


module.exports = router;

这是我的用户模型

const mongoose = require('mongoose');
const passport = require('passport');

const User = mongoose.model('User');

module.exports.register = (req,res,next) => {
    var user = new User();
    user.username = req.body.username;
    user.email = req.body.email;
    user.password = req.body.password;
    if (req.body.username == null || req.body.username == "" || req.body.password == null || req.body.password == "" || req.body.email == null || req.body.email == "" ){
        res.status(422).send(['Ensure Username,Email and Password were provided.']);
    }else{
            user.save((err,doc) => {
                if (!err)
                    res.send(doc);
                else {
                    if (err.code == 11000)
                        res.status(422).send(['Duplicate email address found.']);
                    else
                        return next(err);
                }

            });
    }
}

module.exports.authenticate = (req,next) => {
    // call for passport authentication
    passport.authenticate('local',(err,user,info) => {       
        // error from passport middleware
        if (err) return res.status(400).json(err);
        // registered user
        else if (user) return res.status(200).json({ "token": user.generateJwt() });
        // unkNown user or wrong password
        else return res.status(404).json(info);
    })(req,res);
    next();

}

module.exports.authenticateadmin = (role) => (req,next) => {
    // call for passport authentication
    if(req.user.role !== role){
        res.status(422).send(['You are not an Admin.']);
    }else if(req.user.role == role){
        res.status(422).send(['You are an Admin.']);
    }

}

这是我的jwtHelper，其中包括嵌入到令牌中的用户ID和角色

const mongoose = require('mongoose');
const bcrypt = require('bcryptjs');
const jwt = require('jsonwebtoken');

var userSchema = new mongoose.Schema({
    username: {
        type: String,required: 'Username can\'t be empty'
    },email: {
        type: String,required: 'Email can\'t be empty',unique: true
    },password: {
        type: String,required: 'Password can\'t be empty',minlength: [4,'Password must be at least 4 character long']
    },role: {
        type: String,default: 'user',enum: ['user','admin']
       },saltSecret: String
});

// Custom validation for email
userSchema.path('email').validate((val) => {
    emailRegex = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
    return emailRegex.test(val);
},'Invalid e-mail.');

// Events
userSchema.pre('save',function (next) {
    bcrypt.genSalt(10,salt) => {
        bcrypt.hash(this.password,salt,hash) => {
            this.password = hash;
            this.saltSecret = salt;
            next();
        });
    });
});


// Methods
userSchema.methods.verifyPassword = function (password) {
    return bcrypt.compareSync(password,this.password);
};

userSchema.methods.generateJwt = function () {
    return jwt.sign({ _id: this._id,role: this.role},process.env.JWT_SECRET,{
        expiresIn: process.env.JWT_EXP
    });
}


mongoose.model('User',userSchema);
