how to store JWT token in database - php

Question

I know I'll lose the purpose if I store jwt token in my database but for some reason, i want to store it, how can I do that?
Controller
<?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Tymon\JWTAuth\JWTAuth;
class AuthController extends Controller
{
/**
* #var \Tymon\JWTAuth\JWTAuth
*/
protected $jwt;
public function __construct(JWTAuth $jwt)
{
$this->jwt = $jwt;
}
public function postLogin(Request $request)
{
$this->validate($request, [
'email' => 'required|email|max:255',
'password' => 'required',
]);
try {
if (! $token = $this->jwt->attempt($request->only('email', 'password'))) {
$create_token = User::where('user_id', $login->user_id)->update(['token' => $token]);
return response()->json(['user_not_found'], 404);
}
else {
$create_token = User::where('user_id', auth()->user()->user_id)->update(['token' => $token]);
}
} catch (\Tymon\JWTAuth\Exceptions\TokenExpiredException $e) {
return response()->json(['token_expired'], 500);
} catch (\Tymon\JWTAuth\Exceptions\TokenInvalidException $e) {
return response()->json(['token_invalid'], 500);
} catch (\Tymon\JWTAuth\Exceptions\JWTException $e) {
return response()->json(['token_absent' => $e->getMessage()], 500);
}
return response()->json(compact('token'));
}
public function logout(Request $request)
{
$this->jwt->invalidate($this->jwt->getToken());
return response()->json([
'message' => 'User logged off successfully!'
], 200);
}
}
I tried the method above but i got error saying Call to undefined function App\Http\Controllers\auth()
can anyone help me??

Not advised seeing that json web tokens are time sensitive but I did write something similar but for the use of redis. Looking at your code I would advise you create row for tokens and add it to the public $hidden = ['password','token']. When a user is created, you create and save a token to the database.
