在日志中显示当前用户

我正在尝试创建一个自定义monolog处理器,以将当前用户附加到错误邮件程序。

宣布这样的服务时:

monolog.processor.mail:
        class: MyVendor\Monolog\Processor\MailProcessor
        arguments:
            - @mailer
            - @security.context
        tags:
            - { name: monolog.processor, method: processRecord }

我得到一个循环引用:

[Symfony\Component\DependencyInjection\Exception\ServiceCircularReferenceException]
Circular reference detected for service "monolog.processor.mail",
path: "router -> monolog.logger.router -> monolog.processor.mail
-> security.context -> security.authentication.manager
-> fos_user.user_provider.username_email-> fos_user.user_manager
-> doctrine.orm.default_entity_manager -> doctrine.dbal.default_connection
-> doctrine.dbal.logger -> monolog.logger.doctrine".

这里的最佳实践解决方案是什么?

此主题显示:

  • Setter注射没有解决问题(我也试过这个)
  • 注入容器会导致不定式递归(我尚未确认)

还尝试使用此脚本http://pastebin.com/AuvFgTY3从会话中获取用户。

if ($this->session !== null) {
    if ($this->session->has($this->securityKey)) {
        $token = unserialize($this->session->get($this->securityKey));
        $this->currentUser = $token->getUser();
    }
}

这给出了以下错误:

Warning: ini_set(): A session is active. You cannot change the session module's ini settings at this time in
C:\inetpub\symfony23\vendor\symfony\symfony\src\Symfony\Component\HttpFoundation\Session\Storage\Handler\NativeFileSessionHandler.php
on line 56

我确实知道还没有为很早就请求记录器的服务构建security.context。对于我的课程,这不是问题,因为我将用户设置为undefined。因此,理想情况下,security.context将在创建security.context服务之后进行注册。但是我无法改变记录器的优先级,因为它很早就需要构建。 所以也许这个问题可以解决:如何在security.context初始化之后再次重新创建服务?不确定范围原型是否会对此有所帮助?

在内核请求上创建处理程序并提取用户:

// src/AppBundle/Monolog/UserProcessor.php

namespace AppBundle\Monolog;

use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;

class UserProcessor
{
    private $tokenStorage;
    private $user;

    public function __construct(TokenStorageInterface $tokenStorage)
    {
        $this->tokenStorage = $tokenStorage;
    }

    public function __invoke(array $record)
    {
        if (null !== $this->user) {
            $record['extra']['user'] = $this->user->getUsername();
        }

        return $record;
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        if (null === $token = $this->tokenStorage->getToken()) {
            return;
        }

        if (!is_object($user = $token->getUser())) {
            // e.g. anonymous authentication
            return;
        }

        $this->user = $user;
    }
}

注册新处理器:

# app/config/services.yml

services:
    monolog.processor.user:
    class: AppBundle\Monolog\UserProcessor
    arguments:  ["@security.token_storage"]
    tags:
        - { name: monolog.processor }
        - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
