laravel 8 初始化后添加路由会发生以下错误
Illuminate\Contracts\Container\BindingResolutionException
Target class [IndexController] does not exist.
IndexController 类未找到.我们需要将Route的服务提供者中设置命名空间，我们将注释的 $namespace 取消注释；
<?php
namespace App\Providers;
use Illuminate\Cache\RateLimiting\Limit;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\RateLimiter;
use Illuminate\Support\Facades\Route;
class RouteServiceProvider extends ServiceProvider
{
/**
* The path to the "home" route for your application.
*
* This is used by Laravel authentication to redirect users after login.
*
* @var string
*/
public const HOME = '/home';
/**
* The controller namespace for the application.
*
* When present, controller route declarations will automatically be prefixed with this namespace.
*
* @var string|null
*/
protected $namespace = 'App\\Http\\Controllers'; // 将这行注释取消
.
.
.原因是在服务的启动过程中 会将执行下面的方法，这里的方法，
/**
* Define your route model bindings, pattern filters, etc.
*
* @return void
*/
public function boot()
{
$this->configureRateLimiting();
$this->routes(function () {
Route::prefix('api')
->middleware('api')
->namespace($this->namespace)
->group(base_path('routes/api.php'));
Route::middleware('web')
->namespace($this->namespace)
->group(base_path('routes/web.php'));
});
}
