Laravel show Class signature does not exist - php

Question

Hi I got problem with my Laravel Rest-API apps, whenever i access localhost:8000/api/login in my Postman its say
(1/1) ReflectionException Class signature does not exist
This is my artisan route:list for api/login
POST | api/login | | App\Http\Controllers\Api\UserController#login | api
This is my api route
<?php
use Illuminate\Http\Request;
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
Route::post('oauth/token', '\Laravel\Passport\Http\Controllers\AccessTokenController#issueToken');
Route::group(['namespace' => 'Api'], function () {
Route::post('/login', 'UserController#login');
});
This is my UserController inside Api folder
<?php
namespace App\Http\Controllers\Api;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
use App\User;
use Response;
class UserController extends Controller
{
public function __construct()
{
$this->content = array();
}
public function login()
{
if (Auth::attempt(['email' => request('email'), 'password' => request('password')])) {
$user = Auth::user();
$this->content['token'] = $user->createToken('Pizza App')->accessToken;
$status = 200;
} else {
$this->content['error'] = "Unauthorised";
$status = 401;
}
return response()->json($this->content, $status);
}
}
please help me, if I trying to test my Rest-Api in postman, its keep saying
(1/1) ReflectionException
Class signature does not exist

I think you can use a sample for custom authentication in laravel:
