Call to undefined method Illuminate\Auth\TokenGuard::attempt() in laravel - php

Question

I'm using Laravel 6.x and passport package.
I used api_token in App\User before installing this package.
Now I want to authenticate Users with passport package but I am experiencing this error,
Call to undefined method Illuminate\Auth\TokenGuard::attempt()
This is my gaurd:
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'passport',
'provider' => 'users',
],
],
This is my authController:
<?php
namespace App\Http\Controllers\Api;
use App\Http\Controllers\Controller;
use App\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Str;
class AuthController extends Controller
{
private $successStatus=200;
public function login(){
if(Auth::attempt(['email' => request('email'), 'password' => request('password')])){
$user = Auth::user();
$success['token'] = $user->createToken('MyApp')-> accessToken;
return response()->json(['success' => $success], $this-> successStatus);
}
else{
return response()->json(['error'=>'Unauthorised'], 401);
}
}
}

Answer 1

You may be having the following configuration:
change your auth.php
passport to token
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
],

I changed my controller to this and the problem was resolved
<?php
namespace App\Http\Controllers\Api;
use App\Http\Controllers\Controller;
use App\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Str;
class AuthController extends Controller
{
public function login(Request $request){
$user = User::whereEmail($request->email)->first();
if($user && Hash::check($request->password, $user->password)){
$success['token'] = $user->createToken('tp_#1')-> accessToken;
return response()->json(['success' => $success],200);
}
else{
return response()->json(['status'=>'invalid username or pass !'], 401);
}
}
}
