Question

我刚从2.2.2更新了一个项目到Symfony 2.4.2。升级后，分析器会导致在每个页面底部内嵌显示的异常：

'Symfony \ Component \ DependencyInjection \ Exception \ InactiveScopeException'，消息'您无法创建非活动范围的服务（“请求”）（“请求”）。

( ! ) Fatal error: Uncaught exception 'Symfony\Component\DependencyInjection\Exception\InactiveScopeException' with message 'You cannot create a service ("request") of an inactive scope ("request").' in /var/www/pm/app/cache/dev/appDevDebugProjectContainer.php on line 3776

似乎错误是在探查器侦听内核终止时引起的，但我无法解决问题。

有什么问题？

请求注入的服务示例：

services:
    property.value.form.resolver.number:
        class: Frisbee\ProductBundle\Form\Resolver\PropertyTypeFormResolverNumber
        arguments: [@form.factory, @request]
        scope: request

Answer 1

请尝试使用以下方法之一来处理该异常：

删除scope: request并将arguments: [@form.factory, @request]更改为arguments: [@form.factory, @request=]
使用自Symfony 2.3以来可用的同步服务，其中synchronized: true需要添加到类的服务配置和setter函数中。请求由Symfony DI在范围内可用时设置。参考（http://symfony.com/doc/current/cookbook/service_container/scopes.html）：

services:     
    property.value.form.resolver.number:
        class: Frisbee\ProductBundle\Form\Resolver\PropertyTypeFormResolverNumber
        arguments: [@form.factory]
        synchronized: true
        calls:
            - [setRequest, ["@?request="]]

    /**
     * @param Request $request
    */
    public function setRequest(Request $request = null)
    {
        if ($request !== null) {
            $this->request = $request;
        }
    }

将lazy: true添加到配置中也可以提供帮助：

services:
    property.value.form.resolver.number:
        class: Frisbee\ProductBundle\Form\Resolver\PropertyTypeFormResolverNumber
        arguments: [@form.factory, @request]
        scope: request
        lazy: true

Symfony 2.4.2：您无法创建非活动范围的服务（“请求”）（“请求”）
