JMS Serializer: how to use camel case for properti

问题:

I'm using FOS Rest bundle and JMS Serializer to create a REST Api. The problem is I would like to keep the property names in the JSON response camel cased instead of using _.

For example, I have a property called employeeIdentifier, by default that gets converted to employee_identifier.

I saw that there's an option in the config to disable the lowercase and get rid of the _, but then it becomes EmployeeIdentifier.

Is there any way that JMS Serializer keeps the original name of the property? Thanks in advance

回答1:

I found a way to do it globally, if you want to keep the property names as is you need to use the IdenticalPropertyNamingStrategy

There are several ways to accomplish this, first by changing the config(Thanks @Phantom):

#config.yml
jms_serializer:
    property_naming: 
        id: 'jms_serializer.identical_property_naming_strategy'

Second, you could override the default alias for this

services:
    jms_serializer.naming_strategy:
        alias: jms_serializer.identical_property_naming_strategy

The bundle defines these https://github.com/schmittjoh/JMSSerializerBundle/blob/master/Resources/config/services.xml so you should be able to override them

Another way to do it is when you initialize the builder:

$serializebuilder = JMS\Serializer\SerializerBuilder::create();
$serializebuilder->setPropertyNamingStrategy(new \JMS\Serializer\Naming\IdenticalPropertyNamingStrategy());
$serializer = $serializebuilder->build();

Having upgraded jms/serilizer-bundle from 1.1 to 2.2 the parameter hack described above did not work. You can override the service definition as follows:

#app/config/services.yml
services:
    ....
    jms_serializer.serialized_name_annotation_strategy:
        class: JMS\Serializer\Naming\SerializedNameAnnotationStrategy
        arguments:
            - '@jms_serializer.identical_property_naming_strategy'

I found a way to do it but it's not the best way I think, there's an annotation SerializedName wich allows you to override the property serialization. The problem is that you have to do it one by one on every property with camel case, here's the documentation: YAML: http://jmsyst.com/libs/serializer/master/reference/yml_reference Annotation: http://jmsyst.com/libs/serializer/master/reference/annotations#serializedname

I had to add the following to parameters.yml instead of config.yml:

jms_serializer.serialized_name_annotation_strategy.class: JMS\Serializer\Naming\SerializedNameAnnotationStrategy
