FosRestbundle不断发送text/html作为响应,我们期待json.

Question

这是我们的控制器:

function getLocationsAction(Request $request) {

        $dm = $this->get('doctrine.odm.mongodb.document_manager');
        $query = $dm->createQueryBuilder('MainClassifiedBundle:Location')->select('name', 'state', 'country', 'coordinates');
        $locations = $query->getQuery()->execute();

        $data = array(
            'success' => true,
            'locations' => $locations,
            'displaymessage' => $locations->count() . " Locations Found"
        );

        $view = View::create()->setStatusCode(200)->setData($data);
        return $this->get('fos_rest.view_handler')->handle($view);
    }

这是fosrestbundle的config.yml:

fos_rest:
    view:
        formats:
            json: true
        templating_formats:
            html: true
        force_redirects:
            html: true
        failed_validation: HTTP_BAD_REQUEST
        default_engine: twig

这是路线:

MainClassifiedBundle_get_locations:
    pattern:  /locations/
    defaults: { _controller: MainClassifiedBundle:ClassifiedCrudWebService:getLocations, _format:json}
    requirements:
        _method:  GET

为什么我们得到text/html？我们可以强制将响应强制为application/json吗？

请帮忙,因为这会造成巨大的痛苦

您正在静态创建视图,但未启用任何侦听器.

这种方式不涉及格式猜测.

将格式作为参数传递给函数,并在View对象上设置格式:

function getLocationsAction(Request $request, $_format) {
{
    // ...
    $view = View::create()
         ->setStatusCode(200)
         ->setData($data)
         ->setFormat($_format)   // <- format here
    ;
    return $this->get('fos_rest.view_handler')->handle($view);
}

请参阅文档章节视图层.

如果您想要自动格式猜测,则必须启用侦听器.

fos_rest:
    param_fetcher_listener: true
    body_listener: true
    format_listener: true
    view:
        view_response_listener: 'force'
