是否可以覆盖 symfony2 应用程序/控制台命令?例如,在 FOS UserBundle 中,我想添加更多字段,它会在使用控制台创建用户命令创建用户时询问它。这可能吗,还是我需要在自己的包中创建自己的控制台命令?

向命令中添加更多字段的整个过程是:

1.在您的 AcmeDemoBundle 类中,您必须将 FOSUser 设置为父级:

<?php

namespace Acme\UserBundle;

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

class AcmeUserBundle extends Bundle
{
    public function getParent()
    {
        return 'FOSUserBundle';
    }
}

2.一旦你这样做了,你可以在你的包中重新创建 CreateUserCommand:

<?php

namespace Acme\UserBundle\Command;

use Symfony\Bundle\FrameworkBundle\Command\ContainerAwareCommand;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use FOS\UserBundle\Model\User;

 * @author Thibault Duplessis <thibault.duplessis@gmail.com>
 * @author Luis Cordova <cordoval@gmail.com>
 */
class CreateUserCommand extends ContainerAwareCommand
{
    /**
     * @see Command
     */
    protected function configure()
    {
        $this
            ->setName('fos:user:create')
            ->setDescription('Create a user.')
            ->setDefinition(array(
                new InputArgument('username', InputArgument::REQUIRED, 'The username'),
                new InputArgument('email', InputArgument::REQUIRED, 'The email'),
                new InputArgument('password', InputArgument::REQUIRED, 'The password'),
                new InputArgument('name', InputArgument::REQUIRED, 'The name'),
                new InputOption('super-admin', null, InputOption::VALUE_NONE, 'Set the user as super admin'),
                new InputOption('inactive', null, InputOption::VALUE_NONE, 'Set the user as inactive'),
            ))
            ->setHelp(<<<EOT
The <info>fos:user:create</info> command creates a user:

  <info>php app/console fos:user:create matthieu</info>

This interactive shell will ask you for an email and then a password.

You can alternatively specify the email and password as the second and third arguments:

  <info>php app/console fos:user:create matthieu matthieu@example.com mypassword</info>

You can create a super admin via the super-admin flag:

  <info>php app/console fos:user:create admin --super-admin</info>

You can create an inactive user (will not be able to log in):

  <info>php app/console fos:user:create thibault --inactive</info>

            );
    }

    /**
     * @see Command
     */
    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $username   = $input->getArgument('username');
        $email      = $input->getArgument('email');
        $password   = $input->getArgument('password');
        $name       = $input->getArgument('name');
        $inactive   = $input->getOption('inactive');
        $superadmin = $input->getOption('super-admin');

        $manipulator = $this->getContainer()->get('acme.util.user_manipulator');
        $manipulator->create($username, $password, $email, $name, !$inactive, $superadmin);

        $output->writeln(sprintf('Created user <comment>%s</comment>', $username));
    }

    /**
     * @see Command
     */
    protected function interact(InputInterface $input, OutputInterface $output)
    {
        if (!$input->getArgument('username')) {
            $username = $this->getHelper('dialog')->askAndValidate(
                $output,
                'Please choose a username:',
                function($username) {
                    if (empty($username)) {
                        throw new \Exception('Username can not be empty');
                    }

                    return $username;
                }
            );
            $input->setArgument('username', $username);
        }

        if (!$input->getArgument('email')) {
            $email = $this->getHelper('dialog')->askAndValidate(
                $output,
                'Please choose an email:',
                function($email) {
                    if (empty($email)) {
                        throw new \Exception('Email can not be empty');
                    }

                    return $email;
                }
            );
            $input->setArgument('email', $email);
        }

        if (!$input->getArgument('password')) {
            $password = $this->getHelper('dialog')->askAndValidate(
                $output,
                'Please choose a password:',
                function($password) {
                    if (empty($password)) {
                        throw new \Exception('Password can not be empty');
                    }

                    return $password;
                }
            );
            $input->setArgument('password', $password);
        }

        if (!$input->getArgument('name')) {
            $name = $this->getHelper('dialog')->askAndValidate(
                $output,
                'Please choose a name:',
                function($name) {
                    if (empty($name)) {
                        throw new \Exception('Name can not be empty');
                    }

                    return $name;
                }
            );
            $input->setArgument('name', $name);
        }
    }
}

注意我添加了一个名为 name 的新输入参数,在命令中我使用的是 acme.util.user_manipulator 服务而不是原来的操作系统,我还将处理用户名。

3.创建自己的UserManipulator:

<?php

namespace Acme\UserBundle\Util;

use FOS\UserBundle\Model\UserManagerInterface;

/**
 * Executes some manipulations on the users
 *
 * @author Christophe Coevoet <stof@notk.org>
 * @author Luis Cordova <cordoval@gmail.com>
 */
class UserManipulator
{
    /**
     * User manager
     *
     * @var UserManagerInterface
     */
    private $userManager;

    public function __construct(UserManagerInterface $userManager)
    {
        $this->userManager = $userManager;
    }

    /**
     * Creates a user and returns it.
     *
     * @param string  $username
     * @param string  $password
     * @param string  $email
     * @param string  $name
     * @param Boolean $active
     * @param Boolean $superadmin
     *
     * @return \FOS\UserBundle\Model\UserInterface
     */
    public function create($username, $password, $email, $name, $active, $superadmin)
    {
        $user = $this->userManager->createUser();
        $user->setUsername($username);
        $user->setEmail($email);
        $user->setName($name);
        $user->setPlainPassword($password);
        $user->setEnabled((Boolean)$active);
        $user->setSuperAdmin((Boolean)$superadmin);
        $this->userManager->updateUser($user);

        return $user;
    }
}

在这个类中,我只需要创建函数,因此其他命令(如提升、降级..)不知道您的用户的新属性,因此我不需要创建 CompilerPass 来覆盖整个服务。

4.最后,在 Resources/config 目录中定义这个新的 UserManipulator 服务,并将其添加到 DependencyInjection Extension 中:

services:
    acme.util.user_manipulator:
        class:      Acme\UserBundle\Util\UserManipulator
        arguments:  [@fos_user.user_manager]

完毕!!!

Symfony 4移除了包继承,但你仍然可以通过装饰命令来覆盖它们。它更干净,不需要捆绑。只需将其添加到services.yaml

services:
    App\Command\MyCustomCommand:
        decorates: command_you_want_to_override

请注意,这command_you_want_to_override是一个服务名称。对于旧的,Symfony 3.3 之前的命令,它将是带有点和下划线的小写字母(例如。doctrine_migrations.diff_command),对于较新的命令,它将是一个类名。您可以通过检查其捆绑包的服务配置或搜索debug:container. 在 Linux 或 macOS 上,它将是:

php bin/console debug:container | grep Command

如果您创建(或已经拥有)您自己的作为该捆绑包子的捆绑包(请参阅捆绑包继承),您可以覆盖捆绑包的控制台命令。然后通过在你的包中放置一个与原始命令具有相同位置/名称的类,你可以有效地覆盖它。

例如,要覆盖 FOS/UserBundle/Command/CreateUserCommand.php,创建 MyCompany/UserBundle/Command/CreateUserCommand,其中 MyCompanyUserBundle 将 FOSUserBundle 作为其父级。

您的命令类可以扩展 FOS 命令类以重用(部分)它。但是,查看 FOS CreateUserCommand 后,我认为您需要覆盖所有方法以添加更多输入字段,在这种情况下,这样做没有任何好处。当然,这也意味着您可以在任何包中创建自己的命令,但我认为最好将 FOSUserBundle 的自定义保留在子包中。

在 Symfony (3.3)中,您可以通过以下链接覆盖控制台命令。 https://symfony.com/doc/current/console/calling_commands.html和https://symfony.com/doc/current/console/input.html 上的选项

来自 symfony 文档的代码:

use Symfony\Component\Console\Input\ArrayInput;
// ...

protected function execute(InputInterface $input, OutputInterface $output)
{
    $command = $this->getApplication()->find('demo:greet');

    $arguments = array(
        'command' => 'demo:greet',
        'name'    => 'Fabien',
        '--yell'  => true,
    );

    $greetInput = new ArrayInput($arguments);
    $returnCode = $command->run($greetInput, $output);

    // ...
}
