rest - Symfony2 FOSRESTBundle serialization entity array to JSON -


i have problem trying serialize array of entity game in json. have @ begining circular reference exception managed fix (but maybe solution source of problem).

currently request /games return valide json array not correctly displayed in browser , application not manage parse it. chrome return me following error :

resource interpreted document transferred mime type application/json

what surprising send content-type application/json. same headers used request /players , correctly displayed , parsed no error.

i have bidirectionnal relation between 2 entity : game & player.

entity game :

<?php  namespace appbundle\entity;  use doctrine\orm\mapping orm;  /**  * game  *  * @orm\table(name="game")  * @orm\entity(repositoryclass="appbundle\repository\gamerepository")  */ class game {     /**      * @var int      *      * @orm\column(name="id", type="integer")      * @orm\id      * @orm\generatedvalue(strategy="auto")      */     private $id;      /**      * @orm\manytoone(targetentity="appbundle\entity\tournamenttype", inversedby="games")      */     private $reftype;      /**      * @var \datetime      *      * @orm\column(name="tournamentdate", type="date")      */     private $tournamentdate;      /**      * @orm\manytoone(targetentity="appbundle\entity\ground", inversedby="games")      */     private $ground;      /**      * @orm\manytoone(targetentity="appbundle\entity\referee", inversedby="games")      */     private $referee;      /**     * @orm\manytomany(targetentity="appbundle\entity\player", cascade={"persist"})     */     private $players;      /**      * @var int      *      * @orm\column(name="nbsetsplayerone", type="integer")      */     private $nbsetsplayerone;      /**      * @var int      *      * @orm\column(name="nbsetsplayertwo", type="integer")      */     private $nbsetsplayertwo;      /**     * @var boolean     *      * @orm\column(name="isover", type="boolean")     */     private $isover;      public function __construct(){         $this->players = new \doctrine\common\collections\arraycollection();     }

entity player :

<?php  namespace appbundle\entity;  use doctrine\orm\mapping orm;  /**  * player  *  * @orm\table(name="player")  * @orm\entity(repositoryclass="appbundle\repository\playerrepository")  */ class player {     /**      * @var int      *      * @orm\column(name="id", type="integer")      * @orm\id      * @orm\generatedvalue(strategy="auto")      */     private $id;      /**      * @var string      *      * @orm\column(name="lastname", type="string", length=255)      */     private $lastname;      /**      * @var string      *      * @orm\column(name="firstname", type="string", length=255)      */     private $firstname;      /**      * @var string      *      * @orm\column(name="sexe", type="string", length=255)      */     private $sexe;      /**      * @var string      *      * @orm\column(name="country", type="string", length=255)      */     private $country;      /**      * @var int      *      * @orm\column(name="ranking", type="integer")      */     private $ranking;      /**     * @orm\manytomany(targetentity="appbundle\entity\game", cascade={"persist"})     */      private $games;       public function __construct(){         $this->games = new \doctrine\common\collections\arraycollection();     }

app/config/config.yml :

# fosrestbundle api configuration fos_rest:     format_listener:         rules:             - { path: '^/game', priorities: 'json', fallback_format: json, prefer_extension: true }             - { path: '^/ground', priorities: 'json', fallback_format: json, prefer_extension: true }             - { path: '^/player', priorities: 'json', fallback_format: json, prefer_extension: true }             - { path: '^/referee', priorities: 'json', fallback_format: json, prefer_extension: true }             - { path: '^/tournament-type', priorities: 'json', fallback_format: json, prefer_extension: true }             - { path: '^/user', priorities: 'json', fallback_format: json, prefer_extension: true }             - { path: '^/', priorities: 'json', fallback_format: json, prefer_extension: true }

gamecontroller :

/**  * getgamesaction  *  * @get("/games")  *   * @param request $request  * @return type  */ public function getgamesaction(request $request) {             $games = $this->getdoctrine()->getmanager()->getrepository("appbundle:game")->findall();          if (count($games) === 0) {         $view = $this->view("no game found.", 404);         return $this->handleview();     }      $encoder = new jsonencoder();     $normalizer = new objectnormalizer();     $normalizer->setignoredattributes(array('games', 'players'));     $normalizer->setcircularreferencehandler(function ($object) {         return $object->getid();     });     $serializer = new serializer(array($normalizer), array($encoder));     $data = $serializer->serialize($games, 'json');     $view = $this->view($data)                  ->settemplatevar('games')                  ->settemplate($this->template);     //             ->setheader('content-type', 'application/json; charset=utf-8');     return $this->handleview($view); }

here headers used /games :

you can access example of /games rendered json view : json shared url

application/json content type not taken correclty, manage work around in countroller fixing manually utf-8 encoding (which default encoding of application/json) , string returned json object.

encoding :

$encoder = new jsonencoder(new jsonencode(json_unescaped_unicode), new jsondecode(false));

convert string in json object :

$this->view(json_decode($data, true))

my controller method :

/**  * getgamesaction  *  * @get("/games")  *   * @param request $request  * @return type  */ public function getgamesaction(request $request) {             $games = $this->getdoctrine()->getmanager()->getrepository("appbundle:game")->findall();          if (count($games) === 0) {         $view = $this->view("no game found.", 404);         return $this->handleview();     }      $encoder = new jsonencoder(new jsonencode(json_unescaped_unicode), new jsondecode(false));     $normalizer = new objectnormalizer();     $normalizer->setignoredattributes(array('games', 'players'));     $normalizer->setcircularreferencehandler(function ($object) {         return $object->getid();     });     $serializer = new serializer(array($normalizer), array($encoder));     $data = $serializer->serialize($games, 'json');     $view = $this->view(json_decode($data, true))                  ->settemplatevar('games')                  ->settemplate($this->template)                  ->setheader('content-type', 'application/json; charset=utf-8')                  ->setformat('json');     return $this->handleview($view); }
