Class "SocialWall/Controller/HomeController" 不存在

Question

我的网络应用程序出现此错误：

InvalidArgumentException in ControllerResolver.php line 160: Class "SocialWall/Controller/HomeController" does not exist.

    in ControllerResolver.php line 160
    at ControllerResolver->createController('SocialWall/Controller/HomeController::indexAction') in ControllerResolver.php line 76
    at ControllerResolver->getController(object(Request)) in HttpKernel.php line 136
    at HttpKernel->handleRaw(object(Request), '1') in HttpKernel.php line 68
    at HttpKernel->handle(object(Request), '1', true) in Application.php line 496
    at Application->handle(object(Request)) in Application.php line 477
    at Application->run() in index.php line 16

我使用 Silex ~2.0，我刚刚重构了我的控制器列表：

我的树：

root/app/app.php
root/app/routes.php
root/src/Controller/HomeController.php
root/web/index.php

index.php :

<?php
/** Front controller */

require_once __DIR__.'/../vendor/autoload.php';

$app = new Silex\Application();

require __DIR__.'/../app/config/dev.php';
require __DIR__.'/../app/app.php';
require __DIR__.'/../app/routes.php';

$app->run();

routes.php

    <?php

    // Home page
    $app->get('/', "SocialWall/Controller/HomeController::indexAction")->bind('home');

    // Detailed info about an article
    $app->match('/article/{id}', "SocialWall/Controller/HomeController::articleAction")->bind('article');

    // Login form
    $app->get('/login', "SocialWall/Controller/HomeController::loginAction")->bind('login');   
//...

HomeController.php

    <?php

    namespace SocialWall\Controller;

    use Silex\Application;
    use Symfony\Component\HttpFoundation\Request;
    use SocialWall\Domain\Comment;
    use SocialWall\Form\Type\CommentType;

    class HomeController {

        /**
         * Home page controller.
         *
         * @param Application $app Silex application
         */
        public function indexAction(Application $app) {
            $articles = $app['dao.article']->findAll();
            return $app['twig']->render('index.html.twig', array('articles' => $articles));
        }
//...

我的 composer.json :

{
    "require": {
        "silex/silex": "2.0.*",
        "doctrine/dbal": "2.5.*",
        "twig/twig": "1.24.*",
        "symfony/twig-bridge": "^3.1",
        "symfony/security": "^3.1",
        "symfony/form": "^3.1",
        "symfony/config": "^3.1",
        "symfony/translation": "^3.1",
        "twig/extensions": "^1.3",
        "symfony/validator": "^3.1",
        "sorien/silex-pimple-dumper": "~2.0"
    },
    "require-dev": {
        "phpunit/phpunit": "^5.5",
        "symfony/css-selector": "^3.1",
    "symfony/browser-kit": "^3.1",
    "monolog/monolog": "^1.21"
    },
    "autoload": {
        "psr-4": {"SocialWall\": "src"}
    }
}

怎么了？

[编辑] 好的，我修复它.. 在 route.php 函数的第二个参数中，我已将所有“/”替换为“\”。最初 phpStorm 在所有红色的 '\' 下划线，所以我将 '\' 替换为 '/'.. 谢谢 phpStorm ...

Answer 1

您指定了错误的命名空间：

namespace Controller;

use Silex\Application;
use Symfony\Component\HttpFoundation\Request;
use SocialWall\Domain\Comment;
use SocialWall\Form\Type\CommentType;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class HomeController extends Controller {
    ...

您还需要扩展 Controller。

编辑#2 您是否也更改了路线：

$app->get('/', "Controller/HomeController::indexAction")->bind('home');

// Detailed info about an article
$app->match('/article/{id}', "Controller/HomeController::articleAction")->bind('article');

// Login form
$app->get('/login', "Controller/HomeController::loginAction")->bind('login');   
//...
