Question

我正在尝试使用JMSSerializerBundle，但运行app/console container:debug | grep jms_serializer后未列出该服务

$ app/console container:debug | grep jms_serializer
jms_serializer.json_deserialization_visitor   container JMS\SerializerBundle\Serializer\JsonDeserializationVisit
jms_serializer.json_serialization_visitor     container JMS\SerializerBundle\Serializer\JsonSerializationVisitor
jms_serializer.metadata.lazy_loading_driver   container Metadata\Driver\LazyLoadingDriver
jms_serializer.metadata_driver                container Metadata\Driver\DriverChain
jms_serializer.naming_strategy                container JMS\SerializerBundle\Serializer\Naming\CacheNamingStrate
jms_serializer.xml_deserialization_visitor    container JMS\SerializerBundle\Serializer\XmlDeserializationVisito
jms_serializer.xml_serialization_visitor      container JMS\SerializerBundle\Serializer\XmlSerializationVisitor
jms_serializer.yaml_serialization_visitor     container JMS\SerializerBundle\Serializer\YamlSerializationVisitor

安装后

composer require jms/serializer-bundle

并配置

// in AppKernel::registerBundles()
$bundles = array(
    // ...
    new JMS\SerializerBundle\JMSSerializerBundle($this),
    // ...
);

如果你在某个地方使用

$this->get('jms_serializer')

我收到错误You have requested a non-existent service "jms_serializer".

我如何解决这个问题？

Answer 1

服务的名称是序列化程序。你应该使用以下内容。

$this->get('serializer');

Answer 2

已安装捆绑软件，但没有在bundles.php中自动启用它。必须手动启用它。

启用JMSSerializerBundle：

JMS\SerializerBundle\JMSSerializerBundle::class => ['all' => true],

访问服务：

$serializer = $this->container->get('jms_serializer');

Symfony 4.4

您已请求不存在的服务“jms_serializer”
