通过用户名或电子邮件进行身份验证失败并出现 DBAL 异常：未定义的偏移量：1

Question

从通过电子邮件成功验证（在 4.2.4 中）开始，尝试按照 User Provider docs 添加用户名验证失败

DBAL Exception:... Undefined offset: 1

奇怪的是，如果我运行 SQL 语句如调试分析器 View runnable query 所示，查询运行s 正确并且 returns a非空结果。所以至少存储库可以 return 一个用户名。

我尝试使用 entityManager 重写查询生成器语句；提供带有两个参数的 setParameters() 语句；都无济于事。

编辑#2：

查看跟踪中标识的 Doctrine 代码（见下文），异常发生在

行

[$query, $params, $types] = SQLParserUtils::expandListParameters($query, $params, $types);

$query 和 $params（如 dd(...) 所示）对我来说很有意义。然而，$types 变量是不透明的：它是一个数组 [0 => 102, 1 => 102]。语句 SQLParserUtils....

出现异常

编辑#3：

这是 Doctrine 中发生的事情，但我不知道代码的意图。在 Doctrine\DBAL\SQLParserUtils 中，第 129 - 133 行包含在 foreach () 循环中，运行对 $paramsPos 数组 [0 => 496, 1 => 513] 中的每个元素执行一次，其中值是SQL 语句中可替换参数的位置。 $params 数组最初包含

array:2 [▼
  0 => array:1 [▼
    "username" => "gbrooks"
  ]
  1 => array:1 [▼
    "username" => "gbrooks"
  ]
]

125 - 133 中的代码（如下所示）执行后

$needle    += $paramOffset;
$needlePos += $queryOffset;
$count      = count($params[$needle]);

$params = array_merge(
    array_slice($params, 0, $needle),
    $params[$needle],
    array_slice($params, $needle + 1)
);

$params数组包含

array:2 [▼
  "username" => "gbrooks"
  0 => array:1 [▼
    "username" => "gbrooks"
  ]
]

注意不再存在键1，所以当在下一次循环中遇到第127行的count($params[$needle])语句时（并且$needle现在是1， DBAL Exception Undefined offset: 1 被抛出。

用户资料库：

namespace App\Repository;

use Symfony\Bridge\Doctrine\Security\User\UserLoaderInterface;
use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository implements UserLoaderInterface
{
    public function loadUserByUsername($usernameOrEmail)
    {
        $user = $this->createQueryBuilder('u')
            ->where('u.username = :query OR u.email = :query')
            ->setParameter('query', $usernameOrEmail)
            ->getQuery()
            ->getOneOrNullResult();
    }
}

LoginFormAuthenticator 包含：

public function getUser($credentials, UserProviderInterface $userProvider)
{
    $token = new CsrfToken('authenticate', $credentials['csrf_token']);
    if (!$this->csrfTokenManager->isTokenValid($token)) {
        throw new InvalidCsrfTokenException();
    }

    $user = $this->entityManager->getRepository(User::class)->loadUserByUsername(['username' => $credentials['username']]);

    if (!$user) {
        // fail authentication with a custom error
        throw new CustomUserMessageAuthenticationException('Email could not be found.');
    }

    return $user;
}

将您的存储库更新为：

namespace App\Repository;

use Symfony\Bridge\Doctrine\Security\User\UserLoaderInterface;
use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository implements UserLoaderInterface
{
    public function loadUserByUsername($usernameOrEmail)
    {
        return $this->createQueryBuilder('u')
            ->where('u.username = :query')
            ->orWhere('u.email = :query')
            ->setParameter('query', $usernameOrEmail)
            ->getQuery()
            ->getOneOrNullResult();
    }
}

整个问题是 this->entityManager->getRepository(User::class)->loadUserByUsername(...) 的参数不应该是一个数组，而是一个标量。

也许我可以通过创造像爱丽丝一样的兔子洞来做生意。
