Express Passport twitter策略需要刷新以提供令牌

随着我取得了一些进展，passport推特身份验证正在发挥主要作用，我修改了这个问题：带有Express/Knex/Postgresql后端的VueJS应用程序

问题是，我正在使用jwt将passport twitter与我以前使用的passport local结合起来。因此，我必须为新的Twitter用户生成一个标题令牌。当前使用Twitter登录时，未读取标题标记。如果没有有效的代币，应用程序会做一些疯狂、耗时的事情

以下是来自初始Twitter登录请求的header对象，将令牌显示为未定义的对象：

headers:

{ host: 'localhost:8000',
     connection: 'keep-alive',
     accept: 'application/json, text/plain, */*',
     origin: 'http://localhost:8080',
     'user-agent':
      'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.90 Safari/537.36',
     token: '[object Object]',
     'sec-fetch-mode': 'cors',
     'sec-fetch-site': 'same-site',
     referer:
      'http://localhost:8080/?user=%7B%22id%22%3A10,%22email%22%3Anull,%22token%22%3A%22eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6bnVsbCwiaWQiOjEwLCJleHAiOjE1NzYwNTU1MzYsImlhdCI6MTU3MDg2NzkzNn0.SUYL2KcnK8C9zYNLCcqGF99TjfIRxAcyg0Uc8WjQJD0%22%7D',
     'accept-encoding': 'gzip, deflate, br',
     'accept-language': 'en-US,en;q=0.9',
     'if-none-match': 'W/"79-a0G25cV4V6cfQoTIFr1X/nYU2Kg"' },

刷新浏览器时，标题标记按预期显示，错误消失

标题：

{ host: 'localhost:8000',
     connection: 'keep-alive',
     accept: 'application/json, text/plain, */*',
     origin: 'http://localhost:8080',
     'user-agent':
      'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/77.0.3865.90 Safari/537.36',
     token:
      'Token eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6bnVsbCwiaWQiOjEwLCJleHAiOjE1NzYwNTU1MzYsImlhdCI6MTU3MDg2NzkzNn0.SUYL2KcnK8C9zYNLCcqGF99TjfIRxAcyg0Uc8WjQJD0',
     'sec-fetch-mode': 'cors',
     'sec-fetch-site': 'same-site',
     referer:
      'http://localhost:8080/?user=%7B%22id%22%3A10,%22email%22%3Anull,%22token%22%3A%22eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6bnVsbCwiaWQiOjEwLCJleHAiOjE1NzYwNTU1MzYsImlhdCI6MTU3MDg2NzkzNn0.SUYL2KcnK8C9zYNLCcqGF99TjfIRxAcyg0Uc8WjQJD0%22%7D',

     'if-none-match': 'W/"79-a0G25cV4V6cfQoTIFr1X/nYU2Kg"' }

以下是Express中的相关文件：

authenticate.js是中间件，我使用它从标头获取令牌：

const jwt = require('express-jwt');

const getTokenFromHeaders = (req) => {
  console.log('req from headers is: ', req)
  const { headers: { token } } = req; // same as token = req.headers.token

  if(token && token.split(' ')[0] === 'Token') {
    return token.split(' ')[1];
  }
  return null;

};

const auth = {
  required: jwt({
    secret: 'secret',
    userProperty: 'user',
    getToken: getTokenFromHeaders,
  }),
  optional: jwt({
    secret: 'secret',
    userProperty: 'user',
    getToken: getTokenFromHeaders,
    credentialsRequired: false,
  }),
};

module.exports = auth;

app.js：

const express = require('express')
const bodyParser = require('body-parser')
const path = require('path')
const dotenv = require('dotenv')
const Knex = require('knex')
const { Model } = require('objection')
const cors = require('cors');
const pathfinderUI = require('pathfinder-ui');
const session = require('express-session');
const passport = require('passport')

dotenv.config()
const app = express()

// objection setup
const knexfile = require('../knexfile')
const knex = Knex(knexfile[process.env.NODE_ENV])
Model.knex(knex)

//Configure our app
app.use('/pathfinder', function (req, res, next) {
  pathfinderUI(app)
  next()
}, pathfinderUI.router);

var corsOptions = {
  origin: '*',
  optionsSuccessStatus: 200 // some legacy browsers (IE11, various SmartTVs) choke on 204 
}
app.use(cors(corsOptions));

app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

var sess = {
  secret: 'keyboard cat',
  cookie: {}
}

if (app.get('env') === 'production') {
  app.set('trust proxy', 1) // trust first proxy
  sess.cookie.secure = true // serve secure cookies
}

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

require('./config/passport');

// api routes
// should we refactor this?
app.use("/api/auth", require("./routes/auth"))

    }

    passport.use(new LocalStrategy({

        console.log('hitting the passport twitter strategy')
        if (user) {
          // todo: update user with twitter profile
          return done(null, user);
        } else {

您在插入的表上有任何触发器功能吗？@Max，谢谢您的建议。我设法在错误中找到了方向，并使其正常工作。但是，passport登录不会使标头标记在回调中可用。我得重新振作才能让事情顺利进行
