MEAN-Stack 中的 passport-jwt 返回内部服务器错误 500

Question

我正在使用 passport.js JWT 策略来验证我的 MEAN-Stack 应用程序。不安全的路由正常工作，但我无法让安全的路由正常工作。即使我坚持使用文档，他们也总是返回内部服务器错误 500。这是代码：

我在应用路由之前在 index.js 中初始化：

server.use(passport.initialize());

我的 passport.js 设置文件：

const JwtStrategy = require('passport-jwt').Strategy,
      ExtractJwt = require('passport-jwt').ExtractJwt;

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

const config = require('../config/db');
module.exports = function(passport) {
let opts = {};
opts.jwtFromRequest = ExtractJwt.fromAuthHeaderAsBearerToken();
opts.secretOrKey = config.secret;

passport.use(new JwtStrategy(opts, function(jwt_payload, done) {
  User.findOne({_id: jwt_payload._id}, function(err, user) {
      if (err) {
          return done(err, false);
      }
      if (user) {
         return done(null, user);
      } else {
         return done(null, false);
      }
  });
}));
};

我的路线不起作用：

const express = require('express');
const router = express.Router();
const config = require('../config/db');
const jwt = require('jsonwebtoken');
const User = require('../models/user');
require('../config/passport');
const passport = require('passport');

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

module.exports = router;

我的令牌设置正确，因为我可以手动解码。

我如何从角度调用这条路线（我知道我实际上不需要调用本身的 userId 参数）：

public getProfile(userId) : any{

let httpOptions = {
  headers: new HttpHeaders({ 'Authorization': `Bearer ${this.token}` })
};

this.http.get('http://localhost:8080/api/v1/profile', httpOptions).subscribe(res => {
  console.log('got the profile for user with id: ' + userId + '=> ' + res);
  return res;
}, err => {
  console.log(err);
});
}

感谢任何帮助。提前感谢您的宝贵时间！

我添加了单行 cmets 来命中点，验证点并相应地注释以进一步调试。确认/api/v1/ 是快速根路由。

passport.js

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

module.exports = function(passport) {
  let opts = {
    secretOrKey: config.secret,
    jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
    issuer: 'TODO', // configure issuer
    audience: 'TODO' // configure audience
  };

  passport.use(new JwtStrategy(opts, function(jwt_payload, done) {
    console.log(jwt_payload); // confirm _id is defined

    User.findOne({ _id: jwt_payload._id }, function(err, user) {
      if (err) {
          return done(err, false);
      }

      if (!user) {
         return done(null, false);
      }

      return done(null, user);
    });
  }));
};

route.js

const express = require('express');
const passport = require('passport');
const jwt = require('jsonwebtoken');
const config = require('../config/db');
const User = require('../models/user');
const router = express.Router();

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

router.get('/profile', passport.authenticate('jwt', { session: false }), function(req, res) {
     res.json(req.user); // use req.user not user
});

module.exports = router;
