laravel 8.1.0上的路线

问题描述

大家好，我对laravel 8.1.0有疑问。 现在想在web.PHP文件中创建路由 使用以下代码，我得到一个错误，指出该控制器不存在

web.PHP文件

Route::get('/home/','HomeController@index');

我收到错误“ Illuminate \ Contracts \ Container \ BindingResolutionException 目标类[App \ Http \ Controllers \ HomeController]不存在。“

我在laravel文档中看到，版本8对控制器的调用与以前的版本不同，我已经应用了文档建议的更改，但是一切都保持不变

我已经在app \ providers中的routeserviceprovider.PHP文件中添加了以下代码

protected $namespace = 'App\Http\Controllers';
->namespace($this->namespace)  //inside $this-> routes (function ()
->namespace($this->namespace)  //inside Route::prefix('api')

根据laravel文档，这应该可以工作，但是我仍然遇到相同的错误。 “ Illuminate \ Contracts \ Container \ BindingResolutionException 目标类[App \ Http \ Controllers \ HomeController]不存在。“

我尝试在web.PHP文件中添加use App\Http\Controllers;，但是出现相同的错误消息 我尝试使用Route::get('/home',[App\Http\Controllers\HomeController::class,'index'])->name('home');和Route::get('/home',[HomeController::class,'index']);，但是出现相同的消息错误

web.PHP完整文件

<?PHP

use Illuminate\Support\Facades\Route; 


/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/',function () {
    return view('welcome');
});


Auth::routes();

//Route::get('/home','index']);
Route::get('/persona/','PersonaController@index')->name('per','persona');
Auth::routes();

//Route::get('/home','index'])->name('home');
Route::get('/home/','HomeController@index');

routeservicesprovider.PHP完整文件

<?PHP

namespace sisventas\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';

    /**
     * If specified,this namespace is automatically applied to your controller routes.
     *
     * In addition,it is set as the URL generator's root namespace.
     *
     * @var string
     */
    protected $namespace = 'App\Http\Controllers';  //agregado

    /**
     * Define your route model bindings,pattern filters,etc.
     *
     * @return void
     */
    public function boot()
    {
        $this->configureRateLimiting();

        $this->routes(function () {
            Route::middleware('web')
                ->namespace($this->namespace)  //agregado
                ->group(base_path('routes/web.PHP'));

            Route::prefix('api')
                ->middleware('api')
                ->namespace($this->namespace)  //agregado
                ->group(base_path('routes/api.PHP'));
        });
    }

    /**
     * Configure the rate limiters for the application.
     *
     * @return void
     */
    protected function configureRateLimiting()
    {
        RateLimiter::for('api',function (Request $request) {
            return Limit::perMinute(60);
        });
    }
}

我的家庭控制器文件

<?PHP

namespace sisventas\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Contracts\Support\Renderable
     */
    public function index()
    {
        return view('home');
    }
}

问题与我尝试访问的所有路由相同。 我整天都在尝试修复这些路线，但是却遇到了找不到它们的错误，我想知道如何做，非常感谢您阅读本文：）

解决方法

您的命名空间不正确。应用程序正在 App \ Http \ Controller 中搜索此控制器，但您的控制器命名空间为 sisVentas \ Http \ Controllers 。

根据根目录结构（如果您的根文件夹是 sisVentas ） 您应该使用

    protected $namespace = 'sisVentas\Http\Controllers';

或者，如果您的根是 App ，则应将控制器和提供程序的命名空间更改为

    namespace App\Http\Controllers;
