Check Laravel JWT token is valid or not

Create Middleware using the below command

Command: php artisan make:middleware JwtMiddleware

Paste the below code:

<?php

namespace App\Http\Middleware;

use Closure;

use JWTAuth;

use Exception;

use Tymon\JWTAuth\Http\Middleware\BaseMiddleware;

class JwtMiddleware extends BaseMiddleware

{

    /**

     * Handle incoming requests.

     * @param  \Illuminate\Http\Request  $request

     * @param  \Closure  $next

     * @return mixed

     */

    public function handle($request, Closure $next)

    {

        try {

            $user = JWTAuth::parseToken()->authenticate();

        } catch (Exception $e) {

            if ($e instanceof \Tymon\JWTAuth\Exceptions\TokenInvalidException){

                return response()->json(['status' => 'Token is Invalid']);

            }else if ($e instanceof \Tymon\JWTAuth\Exceptions\TokenExpiredException){

                return response()->json(['status' => 'Token is Expired']);

            }else{

                return response()->json(['status' => 'Authorization Token not found']);

            }

        }

        return $next($request);

    }

}

To use this middleware register this into Kernel. Open app\Http\Kernel.php

...

protected $routeMiddleware = [

...

        'jwt.verify' => \App\Http\Middleware\JwtMiddleware::class,

        'jwt.auth' => 'Tymon\JWTAuth\Middleware\GetUserFromToken',

        'jwt.refresh' => 'Tymon\JWTAuth\Middleware\RefreshToken',

    ];

...

This middleware will verify that the user is authenticated by checking the token sent in the request’s header and It will create a new middleware file in your Middleware directory. . In case of a user is not authenticated middleware throw an UnauthorizedHttpException exception.
