Question

Comment obtenir de réponse au format json(application/json) dans yii?

Answer 1

Créer cette fonction dans votre (de base) Contrôleur:

/**
 * Return data to browser as JSON and end application.
 * @param array $data
 */
protected function renderJSON($data)
{
    header('Content-type: application/json');
    echo CJSON::encode($data);

    foreach (Yii::app()->log->routes as $route) {
        if($route instanceof CWebLogRoute) {
            $route->enabled = false; // disable any weblogroutes
        }
    }
    Yii::app()->end();
}

Puis il suffit d'appeler à la fin de votre action:

$this->renderJSON($yourData);

Answer 2

$this->layout=false;
header('Content-type: application/json');
echo CJavaScript::jsonEncode($arr);
Yii::app()->end(); 

Answer 3

$this->layout=false;
header('Content-type: application/json');
echo json_encode($arr);
Yii::app()->end(); 

Answer 4

class JsonController extends CController {

    protected $jsonData;

    protected function beforeAction($action) {
        ob_clean(); // clear output buffer to avoid rendering anything else
        header('Content-type: application/json'); // set content type header as json
        return parent::beforeAction($action);
    }

    protected function afterAction($action) {
        parent::afterAction($action);
        exit(json_encode($this->jsonData)); // exit with rendering json data
    }

}

class ApiController extends JsonController {

    public function actionIndex() {
        $this->jsonData = array('test');
    }

}

Answer 5

un moyen plus simple en utilisant

echo CJSON::encode($result);

exemple de code:

public function actionSearch(){
    if (Yii::app()->request->isAjaxRequest && isset($_POST['term'])) {
            $models = Model::model()->searchNames($_POST['term']);
            $result = array();
            foreach($models as $m){
                $result[] = array(
                        'name' => $m->name,
                        'id' => $m->id,
                );


            }
            echo CJSON::encode($result);
        }
}

cheers :)
