NodeJS TypeError（'JwtStrategy需要密鑰或密鑰'）;

Question

我已經試過了JwtStrategy實現我取代了

1. User.findOne（{ID：jwt_payload.id}與

2. User.getUserById（jwt_payload._doc._id，（犯錯，用戶）

這裏面user.js的文件 ，我得到了捉迷藏的時候是index.js的錯誤： -

H:\rprfinal\node_modules\passport-jwt\lib\strategy.js:29 
     throw new TypeError('JwtStrategy requires a secret or key'); 
     ^

[nodemon] app crashed - waiting for file changes before starting... 

內user.js的文件： -

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

index.js文件： -

 //Body parser Middleware 
app.use(bodyParser.json()); 

    //Passport Middleware 
app.use(passport.initialize()); 
app.use(passport.session()); 

require('./config/passport')(passport); 

app.use('/users',users); 

passport.js文件： -

const JwtStrategy = require('passport-jwt').Strategy; 
const ExtractJwt = require('passport-jwt').ExtractJwt; 
const User = require('../models/user'); 
const config = require('../config/database'); 

module.exports = function(passport){ 
    let opts = {}; 
    opts.jwtFromRequest = ExtractJwt.fromAuthHeader(); 
    opts.secretOrKey = config.secret; 
    passport.use(new JwtStrategy(opts, (jwt_payload, done) => { 
     User.getUserById(jwt_payload._doc._id, (err, user) => { 
      if(err){ 
       return done(err, false); 
      } 
      if(user){ 
       return done(null, user); 
      } else{ 
       return done(null, false); 
      } 
     }); 
    })); 
} 

和users.js等等H內註冊和驗證

// Authenticate 
router.post('/authenticate',(req, res, next) => { 
const username = req.body.username; 
const password =req.body.password; 

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){ 
     const token = jwt.sign(user, config.secret, { 
      expiresIn: 604800 // 1 Week 
     }); 

    res.json({ 
     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: 'Wrong password'}); 
    } 
}); 
}); 
}); 

Answer 1

嘗試：

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