不幸的是,我在尝试访问登录页面时收到以下错误
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
此处列出了它所指的LoginFormAuthenticator,它需要连接到用户信息(用户名,pw)所在的lc_用户连接。
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;
}
我相信我需要在我的服务中添加一些东西,以便身份验证器能够检索到正确的连接,不幸的是,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
- 我如何解决手头的问题
- 如何防止其他连接发生此问题
- 我是以正确的方式处理这个问题,还是有更好的方法连接到多个数据库
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
(部分)LoginFormAuthenticator的getUser函数:
$em = $this->entityManager;
$repo = $em->getRepository(Users::class, 'lc_users');
$user = $repo->findOneBy(['username' => $credentials['username']]);
如前所述,注入
EntityManager
将获得默认值。条令将为每个经理注册一个名为条令.orm的服务。%manager\u name%\u entity\u manager
因此,如果您需要另一个,您有几个选项:
1。明确配置您的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.为不同的实体经理创建不同的:
_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,将注入适当的管理器:
public function __construct(
EntityManagerInterface $entityManager, // Default manager
EntityManagerInterface $usersManager,
)
3.如果您有许多依赖项,还可以插入ManagerRegistry
(调用getdoctor()
时在AbstractController
中得到的对象)。它充当服务定位器,您可以:
如果您有许多具有不同依赖关系的服务,那么第一个选项可能会很快变得笨拙,而第三个选项将掩盖您的真实依赖关系,并且如果您需要模拟注册表,则会使测试复杂化。尝试更改autowire:true
如前所述,您需要将autowire设置为true以进行自动注入。但是,容器无法知道要注入哪个实体管理器。因此,您需要进一步绑定entity manager变量或手动定义LoginFormAuthenticator。我担心您将不得不花费一些高质量的时间阅读服务上的文档。注入EntityManager
将为您提供默认的文档。如果您需要访问类中的多个连接,您可以插入ManagerRegistry
并检索所需的服务,但请记住,它可能会带来自身的一系列问题。将autowire设置为true会调用错误的数据库。我会花一些时间阅读像@Cerad says这样的服务,然后在找到答案后将答案放在这里。我尝试从不同的资源中学习,但他们没有让我更聪明。如果有人能举一个我可以学习的例子,我将不胜感激。每当我尝试来自不同来源的解决方案时,我都会遇到不同错误。非常感谢@msg,我已成功登录,使用您提供的第一种方法。
use Doctrine\Persistence\ManagerRegistry;
public function __construct(ManagerRegistry $registry) {
$userManager = $registry->getManager('users');
