php - Symfony2 FOSRESTBundle REST API to return PDF -

i've made bundle , rest controller inside. "index" method return array in json-format, it's ok:

mybundle/controller/api/rest/baconcontroller.php

class baconcontroller extends controller implements classresourceinterface {     /**      * @var request $request      * @return array      * @rest\view      */     public function cgetaction(request $request)     {         $mediatype = $request->attributes->get('media_type');         $format = $request->getformat($mediatype);         my_dump($format);          return array(              array("id" => 1, "title" => "hello",),              array("id" => 2, "title" => "there",),         );     } } 

mybundle/resources/config/api/routing_rest.yml

my_api_rest_bacon:     type: rest     resource: "mybundle:api/rest/bacon"     name_prefix: api_rest_bacon_     prefix: /my/bacon 

so, @ point json results returned perfectly:

mysite.com/app_dev.php/api/my/bacon/bacons.json

returns array.

but need controller generate pdf data. want return pdf document when call:

mysite.com/app_dev.php/api/my/bacon/bacons.pdf

i've found half-manuals: rss view handler, rss config.ynal, csv issue answers. , tried make similar:

i've added these lines to

symfony/app/config/config.yml

framework:     [...some old stuff here...]     request:         formats:             pdf: 'application/pdf'  fos_rest:     body_converter:         enabled:              true     format_listener:         rules:             # prototype array             -                 # url path info                 path:                 ~                 # url host name                 host:                 ~                 prefer_extension:     true                 fallback_format:      html                 priorities:           [html,json]             -                 path:                 ~                 host:                 ~                 prefer_extension:     true                 fallback_format:      pdf                 priorities:           [pdf]     view:         # @view or @template         view_response_listener: force #true         formats:             json: true             pdf: true             xls: true             html: false         templating_formats:             pdf: false             xls: false         mime_types: {'pdf': ['application/pdf']}     routing_loader:         default_format: html     param_fetcher_listener: true     body_listener: true     allowed_methods_listener: true  services:     my.view_handler.pdf:         class: lobster\mybundle\view\pdfviewhandler     my.view_handler:         parent: fos_rest.view_handler.default         calls:             - ['registerhandler', [ 'pdf', [@my.view_handler.pdf, 'createresponse'] ] ] 

mybundle/view/pdfviewhandler.php

namespace lobster\mybundle\view;  use fos\restbundle\view\view; use fos\restbundle\view\viewhandler; use symfony\component\httpfoundation\request; use symfony\component\httpfoundation\response;  class pdfviewhandler {     public function createresponse(viewhandler $handler, view $view, request $request, $format)     {         my_dump('pdf createresponse started');          $pdf = "some pdf";          return new response($pdf, 200, $view->getheaders());     } } 

so when call

mysite.com/app_dev.php/api/my/bacon/bacons.pdf

i see error an exception thrown while handling: format html not supported, handler must implemented , function my_dump saves text file info file format: html, not pdf.

also pdf createresponse didn't work. why?

so i've found solution (i describe how enable 2 output formats: pdf , xls):

1) section in config.yml not needed:

framework:     [...some old stuff here...]     request:         formats:             pdf: 'application/pdf' 

2) fos_rest.format_listener section in config.yml should this:

format_listener:     rules:         -             path:                 '^/api/my/bacon.*\.xls$'             host:                 ~             prefer_extension:     false             fallback_format:      json             priorities:           [xls, json]         -             path:                 '^/api/my/bacon.*\.pdf$'             host:                 ~             prefer_extension:     false             fallback_format:      json             priorities:           [pdf, json]         -             path:                 ~             host:                 ~             prefer_extension:     true             fallback_format:      html             priorities:           [html,json] 

3) need add service section fos_rest in config.yml

fos_rest: [...]     service:         view_handler: my.view_handler 

4) services root section in config.yml should like

services:     my.view_handler.xls:         class: lobster\mybundle\view\xlsviewhandler     my.view_handler.pdf:         class: lobster\mybundle\view\pdfviewhandler     my.view_handler:         parent: fos_rest.view_handler.default         calls:             - ['registerhandler', ['xls', [@my.view_handler.xls, 'createresponse'] ] ]             - ['registerhandler', ['pdf', [@my.view_handler.pdf, 'createresponse'] ] ] 

and it. works perfect
