Question

我收到此错误：Notice: Undefined property: MyApp\AuthBundle\Other\AuthenticationSuccessHandler::$httpUtils

在我的登录成功处理程序中使用此代码的结果是：

public function onAuthenticationSuccess(Request $request, TokenInterface $token)
{
    return $this->httpUtils->createRedirectResponse($request, $this->determineTargetUrl($request));
}

我意识到这是因为我的课堂上没有httpUtils属性。但是，我不知道如何注射它？

目前我只在构造函数中使用了RouterInterface $ router和EntityManager $ em。我需要添加更多参数吗？或者更新任何YML文件？

您需要更改构造函数以接受security.http_utils服务：

class LoginSuccessHandler ...
{

    protected $httpUtils;

    ...

    public function __construct(HttpUtils $httpUtils, ...)
    {
        $this->httpUtils = $httpUtils;
        $this->router = $router;
        $this->security = $security;
    }

然后更新您的服务：

login_success_handler:
    class:  AppBundle\EventListener\LoginSuccessHandler
    arguments:  ["@security.http_utils", ... ]
    tags:
      - { name: 'monolog.logger', channel: 'security' }

我还建议您延长DefaultAuthenticationSuccessHandler这将为您提供determineTargetUrl方法：

class LoginSuccessHandler extends DefaultAuthenticationSuccessHandler
{
    public function __construct(HttpUtils $httpUtils, ...)
    {
        parent::__construct($httpUtils);

        $this->router = $router;
        $this->security = $security;
    }

    // ...

} 或者你可以把它复制到你的班级：

/**
 * Builds the target URL according to the defined options.
 *
 * @param Request $request
 *
 * @return string
 */
protected function determineTargetUrl(Request $request)
{
    if ($this->options['always_use_default_target_path']) {
        return $this->options['default_target_path'];
    }

    if ($targetUrl = $request->get($this->options['target_path_parameter'], null, true)) {
        return $targetUrl;
    }

    if (null !== $this->providerKey && $targetUrl = $request->getSession()->get('_security.'.$this->providerKey.'.target_path')) {
        $request->getSession()->remove('_security.'.$this->providerKey.'.target_path');

        return $targetUrl;
    }

    if ($this->options['use_referer'] && ($targetUrl = $request->headers->get('Referer')) && $targetUrl !== $this->httpUtils->generateUri($request, $this->options['login_path'])) {
        return $targetUrl;
    }

    return $this->options['default_target_path'];
}

顺便说一句。如果您想知道http_utils服务在哪里是私有的：

$ php app/console container:debug --show-private | grep security.http_utils
