How to specify default format for FOS\RestBundle to json?

Question

My corresponding configuration is

fos_rest:
    view:
        view_response_listener: force

sensio_framework_extra:
    view:
        annotations: false


        

Answer 1

The final answer is much easier and is irrelevant to FOS\RestBundle:

api:
    resource: "@APIBundle/Controller/"
    type:     annotation
    defaults: {_format: json} # <<<<<<<
    prefix:   /api/

Answer 2

You may specify a default_format that the routing loader will use for the _format parameter if none is specified.

# app/config/config.yml
fos_rest:
    routing_loader:
        default_format: json

By default, routes are generated with {_format} string. If you want to get clean urls (/jobs instead /jobs.{_format}) then all you have to do is add some configuration:

# app/config/config.yml
fos_rest:
    routing_loader:
        include_format:       false

Have a look at the FOSRestBundle documentation for more informations.

I couldn't test this solution myself but following the documentation it seems that you can use a default format by giving rules on path

config.yml

fos_rest:
    format_listener:
        rules:
            # setting fallback_format to json means that instead of considering
            # the next rule in case of a priority mismatch, json will be used
            -
                path: '^/'
                host: 'api.%domain%'
                priorities: ['json', 'xml']
                fallback_format: json
                prefer_extension: false

With such, a request made with Accept-headers containing

text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8,application/json

Will result in a json Request format
