I am trying to verify the bearer token which has been generated after the login request. I have segregated the codes for controllers, middlewares and routes. The login is working fine and is able to generate the token but when I try to verify it I get the following error:

Error: Route.post() requires a callback function but got a [object Undefined]        
    at Route.<computed> [as post] (C:\Users\Desktop\loginapi\node_modules\express\lib\router\route.js:211:15)

Below is the complete Code:

Server.js //Main file

const express = require('express')
const app = express()
require('dotenv').config();

const port = process.env.PORT;


console.log(port)

//initialize middleware
app.use(express.json())


//import routes
const authRoutes = require('./src/routes')

// initialize routes
app.use('/abc', authRoutes)

// console.log();

const appStart = () => {
    try {
        app.listen(port, ()=> {

    } catch (error) {

There is some problem with the middleware verifyTokens ,I have gone through other answers but I am not getting it. Can someone please point it out as to where I am going wrong. It will be very helpful. Thank you

CodePudding user response：

Import verifyTokens without { } it will solve the problem.

In routes/index/js :

const verifyTokens = require('../middlewares/verifyTokens')

CodePudding user response：

Instead of this

router.post('/login', userController.login)
router.post('/profile',verifyToken ,userController.profile)

try this one

router.post('/login',(req, res) => {
  userController.login
});

router.post('/profile', 
 (req, res, next) => {
   verifyToken
 }, 
 (req,res,next) => {
   userController.profile
 }
);
