Symfony 会话避免 _sf2_attributes [英] Symfony session avoid _sf2_attributes

问题描述

显然，我保存到 Symfony2 会话的每个键都在一个子键下:

Apparently every key I save to a Symfony2 session goes under a subkey:

$session->set('foo', 'bar');

将导致:

array('_sf2_attributes' => array('foo' => 'bar'));

这是一个问题，因为我正在构建一个与遗留代码交互的应用程序.我想使用 Symfony 的会话处理程序，但我希望应用程序的旧部分能够从 $_SESSION 读取.换句话说，我想要

This is a problem because I'm building an application that interacts with legacy code. I want to use Symfony's session handler but I want old parts of the app to be able to read from $_SESSION. In other words, I want

$session->set('foo', 'bar');

和

$_SESSION['foo'] = 'bar';

具有相同的效果.

我没有看到任何配置选项来实现这一点.我使用我设置为

I didn't see any configuration option to achieve this. I use a specific session handler which I set to

session:
    handler_id: my_app.session_handler 

所以Symfony 使用不同的会话名称不会有问题.我能想到的唯一解决方案是围绕我的客户会话处理程序 (my_app.session_handler) 创建一个新的会话处理程序类，以检查应用程序是否尝试访问 _sf2_attributes 但我认为它非常丑陋，我什至不确定是否可行.

So it won't be a problem that Symfony uses a different session name. The only solution I can think of is creating a new session handler class around my customer session handler (my_app.session_handler) that checks if the application tries to access _sf2_attributes but I think it's extremely ugly and I'm not even sure if would work.

谢谢！

推荐答案

这不仅是您必须自己实现的处理程序，还应该是您的 SessionStorage.

This is not only the handler that you have to implement on your own, but it also should be your SessionStorage.

默认情况下，Symfony2 使用 NativeSessionStorage.您应该寻找方法 loadSession().如您所见，它使用从 getStorageKey() 接收到的 $key 初始化会话，该会话使用 _sf2_attributes 初始化 - 在 getStorageKey()a href="https://github.com/symfony/HttpFoundation/blob/master/Session/Attribute/AttributeBag.php#L36-L39" rel="nofollow">AttributeBag

By default, Symfony2 uses NativeSessionStorage. You should be looking for the method loadSession(). As you can see, it initializes a session with the $key received from getStorageKey(), which is initialized with _sf2_attributes here - in the AttributeBag

如果您在注入自定义会话存储时遇到问题，请告诉我.

Let me know if you have problems injecting custom session storage.
