[英]Use custom service in a Symfony Command
我创建了一个带有我想从命令窗口运行的 PHP 函数的类。
因此,我创建了一个类扩展命令,但我遇到了麻烦,因为我必须调用EntityManagerInterface
和UserPasswordHasherInterface
。
如果我将它们放在构造函数中并创建一个新实例,我会被要求提供两个参数,我猜不出来。 那么当我调用我的方法时使用这两个接口的解决方案是什么?
这是我的 2 个文件:TestHashPassword
<?php
namespace App;
use App\Entity\User;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;
class TestHashPassword
{
private $entityManager;
private $passwordHasher;
public function __construct(EntityManagerInterface $em,UserPasswordHasherInterface $passwordHasherInterface){
$this->entityManager = $em;
$this->passwordHasher = $passwordHasherInterface;
parent::__construct();
}
public function hashPassword(){
$em = $this->entityManager; // will throw an error "Using $this when not in object context"
$userAll = $em
->getRepository(User::class)
->findAll();
echo("coucou");
foreach($userAll as $user){
$comb = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890';
$pass = array();
$combLen = strlen($comb) - 1;
for ($i = 0; $i < 8; $i++) {
$n = rand(0, $combLen);
$pass[] = $comb[$n];
};
echo("coucou");
$user->setDescription($pass);
$hashedPassword = $this->passwordHasher->hashPassword(
$user,
$pass
);
$user->setPassword($hashedPassword);
$this->entityManager->persist($user);
$this->entityManager->flush();
}
}
}
TestHashPasswordCommand.php
<?php
namespace App\Command;
use App\Entity\User;
use App\TestHashPassword;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputArgument;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Style\SymfonyStyle;
use Symfony\Component\PasswordHasher\Hasher\UserPasswordHasherInterface;
class TestHashPasswordCommand extends Command
{
protected static $defaultName = 'test-hash-password';
protected static $defaultDescription = 'Add a short description for your command';
protected function configure(): void
{
$this
->addArgument('arg1', InputArgument::OPTIONAL, 'Argument description')
->addOption('option1', null, InputOption::VALUE_NONE, 'Option description')
;
}
protected function execute(InputInterface $input, OutputInterface $output): int
{
$io = new SymfonyStyle($input, $output);
$arg1 = $input->getArgument('arg1');
if ($arg1) {
$io->note(sprintf('You passed an argument: %s', $arg1));
}
if ($input->getOption('option1')) {
// ...
}
$io->success('You have a new command! Now make it your own! Pass --help to see your options.');
$foobar = new TestHashPassword(); // 2 parameters necessary
$foobar->hashPassword();
// TestHashPassword::hashPassword(); // will give an error saying I cannot use $this there
return Command::SUCCESS;
}
}
我在命令 CLI 中运行: php .\bin\console test-hash-password
您也应该能够为您的命令使用自动装配(使用默认的 services.yaml 配置)。
而不是创建一个new TestHashPassword();
,使用自动布线将其作为服务注入。
在您的命令中添加__construct
:
use App\TestHashPassword;
class TestHashPasswordCommand extends Command
{
protected $testHashPassword;
protected static $defaultName = 'test-hash-password';
protected static $defaultDescription = 'Add a short description for your command';
public function __construct(TestHashPassword $testHashPassword)
{
$this->testHashPassword = $testHashPassword;
}
然后将它与您的初始化变量一起使用:
$this->testHashPassword->hashPassword();
PS:为什么会有parent::__construct();
如果它不扩展类,在您的服务构造函数中?
