如何覆盖Laravel 8身份验证函数

use Illuminate\Auth\GuardHelpers;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Contracts\Auth\Guard;
use Illuminate\Contracts\Auth\UserProvider;

class CustomGuard implements Guard
{
    use GuardHelpers;

    protected $userProvider;
    protected $currentRequest;

    public function __construct(UserProvider $userProvider, $currentRequest)
    {
        $this->userProvider = $userProvider;
        $this->currentRequest = $currentRequest;
    }

    public function authenticate(array $credentials = [])
    {
        // 自定义身份验证逻辑
        $user = $this->userProvider->retrieveByCredentials($credentials);

        if ($user && $this->provider->validateCredentials($user, $credentials)) {
            return $this->login($user);
        }

        return false;
    }

    // 实现其他必要的接口方法...
}
