护照认证回调不调用护照中间件

Question

我正在尝试通过使用带有护照 JwtStrategy 的 JSON Web 令牌来测试对特定路由的 GET 请求是否受到保护；但是，我的server.js 文件中的passport.use 中间件函数似乎没有执行。我在那里的 console.log 永远不会出现在我的 shell/终端中。我的登录路线有效，但配置文件路线无效。我正在使用邮递员，我在 GET 方法中输入了http://localhost:3000/profile，在Headers 选项卡中，我为密钥和值选择了授权，我复制并粘贴了长 JSON Web 令牌字符串，但它一直说未经授权。那是因为我的 passport.use 函数永远不会被执行。

//Server.js 文件

var JwtStrategy = require("passport-jwt").Strategy;
var ExtractJwt = require("passport-jwt").ExtractJwt;

var User = require("../models/user");
var config = require('./secret');

app.use(passport.initialize());
app.use(passport.session());

let options = {};
//pass token back and forth
options.jwtFromRequest = ExtractJwt.fromAuthHeader();
options.secretOrKey = config;
passport.use(new JwtStrategy(options, (jwt_payload, done) => {
  *******************************************
  //this console log doesn't show up in shell which makes be believe its never getting here
  *******************************************
  console.log("JWT PAYLOAD", jwt_payload)
  User.getUserById(jwt_payload._id, (err, user) => {
    if(err){
      return done(err, false);
    }

    if(user){ //null for error
      return done(null, user);
    }else{
      return done(null, false);
    }
  });
}));

//调用passport.authenticate回调的路由文件

var passport = require('passport');
var jwt = require('jsonwebtoken');
var secret = require('../config/secret')

var User = require('../models/user');

router.post('/login', (req, res) => {
    var username = req.body.username;
    var password = req.body.password;
    console.log("SECRET2", secret);
    console.log("SECRET", secret.secret);
    User.getUserByUsername(username, (err, user) => {
        if(err){
            throw err;
        }
        if(!user){
            return res.json({ success: false, msg: "User not found"});
        }

        User.comparePassword(password, user.password, (err, isMatch) => {
            if(err){
                throw err;
            }
            if(isMatch){
                var token = jwt.sign(user, secret.secret, {
                    expiresIn: 604800 //1 week in seconds, token expires and requires to log back in
                });

                console.log('TOKEN IN LOGIN ROUTE', token)

                res.json({
                    //tokens are then stored in local storage or cookie
                    success: true,
                    token: 'JWT ' + token,
                    user: {
                        id: user._id,
                        name: user.name,
                        username: user.username,
                        email: user.email
                    }
                });
            }else{
                return res.json({ success: false, msg: "Incorrect password"});
            }
        });
    });
});

router.get('/profile', passport.authenticate('jwt', {session:false}), (req, res) => {
    res.json({user: req.user});
});

//用户模型

var mongoose = require('mongoose');
var bcrypt = require('bcryptjs');

var Schema = mongoose.Schema;

var UserSchema = new Schema({
  name: {
    type: String,
    trim: true,
    required: "First Name is Required"
  },
  email: {
    type: String,
    required: true
  },
  username: {
    type: String,
    required: true
  },
  password: {
    type: String,
    required: true
  }
});

var User = mongoose.model("User", UserSchema);

module.exports = User;

//Alternate syntax for exporting Schema
// var User = module.exports = mongoose.model("User", UserSchema);

module.exports.getUserById = function(id, callback){
    User.findById(id, callback);
}

module.exports.getUserByUsername = function(username, callback){
    var query = { username: username }
    User.findOne(query, callback);
}

//Custom User model function that will take in the newUser object and hash the password.
module.exports.addUser = function(newUser, callback){
    bcrypt.genSalt(10, (err, salt) => {
        bcrypt.hash(newUser.password, salt, (err, hash) => {
            if(err){
                throw err
            }

            newUser.password = hash;
            newUser.save(callback);
        });
    });
}

module.exports.comparePassword = function(password, hash, callback){
    bcrypt.compare(password, hash, (err, isMatch) => {
        if(err){
            throw err
        }
        callback(null, isMatch);
    });
}

更新： 我尝试在“JWT”之后为邮递员中的授权值添加一个空格，但它仍然不起作用，并且控制台日志没有显示。是不是因为我没有将我在server.js 中定义的passport.use 导出或链接到我的路由文件中的 GET '/profile' 路由？

更新 2：添加模型和登录路径

Answer 1

也许有必要包含更多代码才能看到您的问题，但该策略似乎没有正确导出。创建新策略时，您可以在入口点中包含一个“别名”以使用它：

passport.use('local-login', new JwtStrategy(options, (jwt_payload, done) => {
    ....
}

router.get('/profile', passport.authenticate('local-login', {session:false}), (req, res) => {
    res.json({user: req.user});
});
