Symfony2 - 如何扩展供应商捆绑（例如FOSFacebookBundle） [英] Symfony2 - how to extend a vendor bundle (e.g. of FOSFacebookBundle)

问题描述

场景

我正在使用一个软件包（FOSFacebookBundle），允许我在配置中为一个Facebook应用设置参数。一切工作都很好，但现在我不仅要设置一个应用程序，还可以设置多个。

I'm using a bundle (FOSFacebookBundle) that allows me to set parameters for exactly one facebook app in my configuration. Everything works perfectly fine, but now I need to set not only one app, but multiple.

我的方法：

我创建了一个AcmeFacebookBundle，它允许在像这样的数组中定义多个应用程序（在 Acme\FacebookBundle\DependencyInjection\Configuration 中定义的配置） ：

I've created a AcmeFacebookBundle, which allows multiple apps to be defined (configuration defined in Acme\FacebookBundle\DependencyInjection\Configuration) in an array like so:

acme_facebook:
    apps:
        some_competition:
            server_url: %acme.facebook.some_competition.server_url%
            file:   %kernel.root_dir%/../vendor/facebook/php-sdk/src/base_facebook.php
            alias:  facebook
            app_id: %acme.facebook.some_competition.app_id%
            secret: % acme .facebook.some_competition.secret%
            cookie: true
            permissions: [email, user_birthday, user_location]
        some_other_competition:
            server_url: %acme.facebook. some_other_competition.server_url%
            file:   %kernel.root_dir%/../vendor/facebook/php-sdk/src/base_facebook.php
            alias:  facebook
            app_id: %acme.facebook. some_other_competition.app_id%
            secret: % acme .facebook. some_other_competition.secret%
            cookie: true
            permissions: [email, user_birthday, user_location]

在 Acme\FacebookBundle\DependencyInjection\AcmeFacebookExtension 中，然后循环遍历所有应用程序。这个想法是将server_url参数与当前URL进行比较，并覆盖我的fos_facebook配置。

In Acme\FacebookBundle\DependencyInjection\AcmeFacebookExtension I am then looping through all apps. The idea is to compare the server_url parameter against the current URL and override the fos_facebook configuration with mine.

class AcmeFacebookExtension extends Extension
{
    ...
    /**
     * {@inheritDoc}
     */
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        foreach ($config['apps'] as $app)
        {
            // check for matching path here?
            foreach (array('file', 'app_id', 'secret', 'cookie', 'domain', 'logging', 'culture', 'permissions') as $attribute)
            {
                $container->setParameter('fos_facebook.' . $attribute, $app[$attribute]);
            }
        }
    }

问题： / strong>

Problem:

但这正是我被卡住的地方。显然，我没有访问Request对象或AcmeFacebookExtension内的DiC进行此比较。
我的做法完全错了？你有什么更好的想法来解决这个问题吗？

But this is exactly where I'm stuck. Obviously, I have no access to the Request object or the DiC from within AcmeFacebookExtension to do this comparison. Am I going completely wrong in my approach? Do you have any better idea on how to tackle this problem?

推荐答案

你想要创建的是一个 CompilerPass ，以便在加载所有其他配置后，您可以操作 Container 。这些应该让你开始：

What you want to create is a CompilerPass so that you can manipulate the Container after all other configuration has loaded. These should get you started:

• Symfony2：服务容器编译器通过




• 创建一个 CompilerPass

• Symfony2: Service Container Compiler Passes
• Symfony2: Manipulating Service Parameters and Definitions
• Create a CompilerPass
