覆盖 symfony2 控制台命令? [英] Override symfony2 console commands?

问题描述

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，它在使用其控制台创建用户命令创建用户时询问.这是可能的，还是我需要在自己的包中创建自己的控制台命令?

Is it possible to override symfony2 app/console commands? For example, in the FOS UserBundle I'd like to add a few more fields it asks when it creates a user with its console create user command. Is this possible, or do I need to create my own console command in my own bundle?

推荐答案

向命令中添加更多字段的整个过程是:

The whole process for adding more fields to the command is:

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

1.In your AcmeDemoBundle class you must set FOSUser as parent:

<?php

namespace AcmeUserBundle;

use SymfonyComponentHttpKernelBundleBundle;
use SymfonyComponentDependencyInjectionContainerBuilder;

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

2.完成后，您可以在包中重新创建 CreateUserCommand:

2.Once you do that you can recreate the CreateUserCommand in your bundle:

<?php

namespace AcmeUserBundleCommand;

use SymfonyBundleFrameworkBundleCommandContainerAwareCommand;
use SymfonyComponentConsoleInputInputArgument;
use SymfonyComponentConsoleInputInputOption;
use SymfonyComponentConsoleInputInputInterface;
use SymfonyComponentConsoleOutputOutputInterface;
use FOSUserBundleModelUser;

/**
 * @author Matthieu Bontemps <[e-mail]>
 * @author Thibault Duplessis <[e-mail]>
 * @author Luis Cordova <[e-mail]>
 */
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 [e-mail] 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>

    }

    /**

    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);
        }
    }
}

请注意，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.

Note I have added a new input argument called name and inside the command I am using an acme.util.user_manipulator service instead of the original one os there I am going to process also the user's name.

3.创建自己的UserManipulator:

3.Create your own UserManipulator:

<?php

namespace AcmeUserBundleUtil;

use FOSUserBundleModelUserManagerInterface;

/**
 * Executes some manipulations on the users
 *
 * @author Christophe Coevoet <[e-mail]>
 * @author Luis Cordova <[e-mail]>
 */
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 $superadmin
     *
     * @return FOSUserBundleModelUserInterface
     */
    public function create($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 create 函数，所以其余的命令(如提升、降级...)不知道您用户的新属性，因此我不需要创建 CompilerPass 来覆盖整个服务.

In this class I only need the create function so the rest of commands like promote, demote.. does not know about your user's new properties so I do not need to create a CompilerPass to override the whole service.

4.最后，在Resources/config目录下定义这个新的UserManipulator服务并添加到DependencyInjection Extension:

4.Finally, define this new UserManipulator service in the Resources/config directory and add it to the DependencyInjection Extension:

services:
    acme.util.user_manipulator:
        class:      AcmeUserBundleUtilUserManipulator
        arguments:  [@fos_user.user_manager]

完成！！！
