如何解决函数`LoginFormAuthenticator :: __ construct`的参数太少,0恰好传递了4个预期值
我创建了多个原则连接和orm实体管理器,并禁用了自动装配。

Too few arguments to function App\Security\LoginFormAuthenticator::__construct(),0 passed in /var/www/html/app/var/cache/dev/Container12fc4el/getSecurity_Firewall_Map_Context_MainService.PHP on line 53 and exactly 4 expected
它所引用的LoginFormAuthenticator在此处列出,并且需要连接到用户信息(用户名,pw)所在的lc_users连接。 我将需要其他连接来获取客户端数据。
class LoginFormAuthenticator extends AbstractformLoginAuthenticator implements PasswordAuthenticatedInterface
{
use TargetPathTrait;
public const LOGIN_ROUTE = 'app_login';
private $entityManager;
private $urlGenerator;
private $csrftokenManager;
private $passwordEncoder;
public function __construct(EntityManagerInterface $entityManager,UrlGeneratorInterface $urlGenerator,CsrftokenManagerInterface $csrftokenManager,UserPasswordEncoderInterface $passwordEncoder)
{
$this->entityManager = $entityManager;
$this->urlGenerator = $urlGenerator;
$this->csrftokenManager = $csrftokenManager;
$this->passwordEncoder = $passwordEncoder;
}
我认为我需要在服务中添加一些内容,以便身份验证器可以检索正确的连接,很遗憾,我对此事的了解还不够。
我需要为多个客户端使用多个数据库。
在此先感谢您的帮助,随时询问更多信息。
编辑: 感谢@msg的回答;我设法通过以下代码使其工作:
app / config / services.yaml:
App\Security\LoginFormAuthenticator:
autowire: true
tags: ["doctrine.repository_service"]
arguments:
$entityManager: "@doctrine.orm.lc_users_entity_manager"
app / config / doctrine.yaml:
orm:
default_entity_manager: default
entity_managers:
auto_generate_proxy_classes: "%kernel.debug%"
auto_mapping: true
default:
...
lc_users:
connection: lc_users
mappings:
App\Entity\lmc_lemoncake:
is_bundle: false
type: annotation
dir: "%kernel.project_dir%/src/Entity/lmc_users"
prefix: 'App\Entity\lmc_users'
alias: lc_users
LoginFormAuthenticator的getUser函数(的一部分):
$em = $this->entityManager;
$repo = $em->getRepository(Users::class,'lc_users');
$user = $repo->findOneBy(['username' => $credentials['username']]);
解决方法
如前所述,注入EntityManager
将使您得到default
。原则将为每个经理注册一项服务,名称为doctrine.orm.%manager_name%_entity_manager
。
因此,如果您需要其他选项,则有几种选择:
1。。明确配置服务以使用所需的管理器:
services:
App\Security\LoginFormAuthenticator:
arguments:
# Override the Manager,other arguments will be autowired.
$entityManager: '@doctrine.orm.lc_users_entity_manager'
2。。为不同的实体管理者创建不同的bindings:
_defauts:
bind:
$cvoManager: '@doctrine.orm.lc_cvo_entity_manager'
$usersManager: '@doctrine.orm.lc_users_entity_manager'
# Other managers...
根据依赖项上的变量名称,将注入适当的管理器:
public function __construct(
EntityManagerInterface $entityManager,// Default manager
EntityManagerInterface $usersManager,)
3。。如果您有很多依赖项,还可以注入ManagerRegistry
(调用AbstractController
时在getDoctrine()
中获得的对象)。它充当服务定位器,您可以在其中retrieve managers or repositories:
use Doctrine\Persistence\ManagerRegistry;
public function __construct(ManagerRegistry $registry) {
$userManager = $registry->getManager('users');
}
如果您有许多具有不同依赖项的服务,则第一个选项很快就会变得笨拙;如果需要模拟注册表,第三个选项将掩盖您的真实依赖项并使测试复杂化。
