Passport：错误：passport.initialize() 中间件未使用；

Question

我有一个带有 MongoDB 和 Mongoose 的快速服务器，并使用护照通过 JWT 进行身份验证，但出现标题中的错误。

我正在关注 passport-jwt 文档，但仍然收到错误消息。我做错了什么？

以下是使用有效 JWT 在 localhost3090 上进行 GET 调用时的错误消息：

我的服务器/控制器/authentication.js：

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

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

function tokenForUser(user) {
  const timestamp = new Date().getTime();
  return jwt.encode({ sub: user.id, iat: timestamp }, config.secret);
 }

exports.signup = function (req, res, next) {
  const email = req.body.email;
  const password = req.body.password;

  if (!email || !password) {
    return res.status(422).send({ error: 'You must provide an email and 
  password' });
  }

  // see if user with the given email exists
User.findOne({ email: email }, function (err, existingUser) {
  if (err) { return next(err); }
  if (existingUser) {
    return res.status(422).send({ error: 'A user with that email 
 already exists' });
  }
  const user = new User({
    email: email,
    password: password
});

  user.save(function (err) {
    if (err) { return next(err); }
    res.json({ token: tokenForUser(user), iat: jwt.iat });
  });
});
};

我的服务器/services/passport.js

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

const jwtOptions = {
  jwtFromRequest: ExtractJwt.fromHeader('authorization'),
  secretOrKey: config.secret
};

const jwtLogin = new JwtStrategy(jwtOptions, function (payload, done) {
  User.findById(payload.sub, function (err, user) {
    if (err) { return done(err, false); }
    if (user) {
      done(null, user);
    } else {
      done(null, false);
    }
  });
});

passport.use(jwtLogin);

我的服务器/router.js

const passport = require('passport');
const Authentication = require('./controllers/authentication');
const passportService = require('./services/passport');

const requireAuth = passport.authenticate('jwt', { sesssion: false });

module.exports = function (app) {
  app.get('/', requireAuth, function (req, res) {
    res.send({ hi: 'there' });
  });

  app.post('/signup', Authentication.signup);
};

使用前需要初始化护照模块：

let app = express();
app.use(passport.initialize());
