将 Silex v1.3 迁移到 v2，ClassNotFoundException

Question

我最近通过更改 composer.json

中的 3 行将 Silex v1.3 迁移到 v2

    "silex/silex": "~2.0",
    "silex/web-profiler": "~2.0",
    "deralex/yaml-config-service-provider": "2.0.x-dev"

但是由于 Silex 无法找到很多 class...

这是我的 app.php 文件，在 Silex 1.3 中正确加载我需要的一切：

<?php

use Silex\Application;
use Silex\Provider\TwigServiceProvider;
use Silex\Provider\UrlGeneratorServiceProvider;
use Silex\Provider\ValidatorServiceProvider;
use Silex\Provider\ServiceControllerServiceProvider;
use Silex\Provider\HttpFragmentServiceProvider;
use Silex\Provider\SessionServiceProvider;
use Silex\Provider\SecurityServiceProvider;
use Silex\Provider\FormServiceProvider;
use Manager\ManagerProvider;

$app = new Application();
$app->register(new UrlGeneratorServiceProvider());
$app->register(new ValidatorServiceProvider());
$app->register(new ServiceControllerServiceProvider());
$app->register(new TwigServiceProvider());
$app->register(new HttpFragmentServiceProvider());
$app->register(new SessionServiceProvider());
$app->register(new FormServiceProvider());
$app->register(new Silex\Provider\TranslationServiceProvider(), array(
    'translator.messages' => array(),
));
$app->register(new SecurityServiceProvider(), [
    'security.firewalls'    => [
        'foo'     => [ 'pattern' => '^/foo' ],
        'default' => [
            'pattern'   => '^.*$',
            'anonymous' => true,
            'form'      => [ 'login_path' => '/login','check_path' => 'connexion' ],
            'logout'    => [ 'logout_path' => '/logout' ],
            'users'     => $app->share( function () use ( $app ) {
                return new Authenticate\UserProvider( $app['manager.user'] );
            } ),
        ],
    ],
    'security.access_rules' => [
        [ '^/.+$','IS_AUTHENTICATED_ANONYMOUSLY' ],
        [ '^/foo$','' ]
    ]
]);
$app['twig'] = $app->share($app->extend('twig', function ($twig, $app) {
    // add custom globals, filters, tags, ...

    return $twig;
}));

$app->register(new DerAlex\Silex\YamlConfigServiceProvider(__DIR__ . '/../app/settings.yml'));
$app->register(new ManagerProvider($app));

return $app;

第一个错误：

ClassNotFoundException in app.php line 15:
Attempted to load class "UrlGeneratorServiceProvider" from namespace "Silex\Provider".
Did you forget a "use" statement for another namespace?

第二个错误：

UndefinedMethodException in app.php line 33:
Attempted to call an undefined method named "share" of class "Silex\Application".

第三个错误：

ClassNotFoundException in app.php line 56:
Attempted to load class "YamlConfigServiceProvider" from namespace "DerAlex\Silex".
Did you forget a "use" statement for "DerAlex\Pimple\YamlConfigServiceProvider"?

第四个错误：

ClassNotFoundException in ManagerProvider.php line 12:
Attempted to load interface "ServiceProviderInterface" from namespace "Silex".
Did you forget a "use" statement for "Pimple\ServiceProviderInterface"?

我不知道应该更改什么以及如何纠正... 感谢帮助

Answer 1

UrlGeneratorServiceProvider 被替换为 RoutingServiceProvider

$app->register(new RoutingServiceProvider());
方法 share 已从 Pimple 中删除。只需设置 returns 对象共享某个对象的函数。

$app['object'] = function() { return new Object(); }
可能是作曲家未设置为使用命名空间 DerAlex\... 自动加载 classes。尝试使用 \DerAlex\Silex\YamlConfigServiceProvider.
添加 use 语句 use Pimple\ServiceProviderInterface 或将此 class 用作 \Pimple\ServiceProviderInterface。
