im getting this error in Laravel 8 after using php artisan route:list:
Illuminate\Contracts\Container\BindingResolutionException
Target class [Api\UserController] does not exist.
I have a controller in App\Http\Controllers\Api:
<?php
namespace App\Http\Controllers\Api;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class UserController extends Controller
{
public function index()
{
$users = User::all();
return responde()->json($users);
}
}
routes/api.php:
<?php
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\Api\UserController;
Route::get('users', 'Api\\UserController#index');
Im new at Laravel

Answer 1

Since you are importing the use App\Http\Controllers\Api\UserController namespace statement you can use the ::class notation for controller class. It will also have added benefits as IDE will be able to navigate to the path unlike string
Since Laravel 8, I guess the default namespace is no longer defined to be App\Http\Controllers in the RouteServiceProvider, rather it is left upto the developer to define the default namespace by setting $namespace property with the desired value.
<?php
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\Api\UserController;
Route::get('users', [UserController::class, 'index']);

On Larvel 8 you can't wright route as we used to before, the next syntax is this
Controller:
<?php
namespace App\Http\Controllers\Api;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
user App\Models\User;
class UserController extends Controller
{
public function index()
{
$users = User::all();
return responde()->json($users);
}
}
api.php:
<?php
use Illuminate\Support\Facades\Route;
Route::get('users', '\App\Http\Controllers\Api\UserController#index');
Or
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\Api\UserController;
Route::get('/Pages', [UserController::class, 'index']);
