无法从 Symfony 3.4 中的接口 CompilerPassInterface 扩展

Question

我想通过在 Symfony 3.4 中使用 compilerPass 来覆盖 FosUserbundle 的控制器 (RegistartionController)，所以这是我的代码

=== RegisterUserCompilerPass ===

<?php

namespace myBundle;

use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;


class RegisterUserCompilerPass extends CompilerPassInterface
{
    public function process(ContainerBuilder $container)
    {
        $container
            ->getDefinition('fos_user.registration.controller')
            ->setClass(MyBundle\Controller\ReplaceRegistrationController::class) ; 
    }
}

这是添加到主包时的文件 class

<?php

namespace MyBundle;


use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Bundle\Bundle;

use MyBundle\DependencyInjection\Compiler\RegisterUserCompilerPass  ; 


// use Crypto\UserBundle\Manager\ReplaceRegistration ; 

class CryptoUserBundle extends Bundle
{
    public function build(ContainerBuilder $container)
    {
     parent::build($container);
       $container->addCompilerPass(new RegisterUserCompilerPass() );
    }

}

当访问我的注册路径时，我得到

Compile Error: Class MyBundle\DependencyInjection\Compiler\RegisterUserCompilerPass cannot extend from interface Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface

Answer 1

class RegisterUserCompilerPass extends CompilerPassInterface

应该是

class RegisterUserCompilerPass implements CompilerPassInterface

见PHP can't extend from interface?
