rest - FOS 休息包 : unable to find template

Question

我得到了异常(exception):

Unable to find template ""

其他类似的问题没有帮助；奇怪的是，它运行良好，然后突然开始给我这个异常(exception)。

Composer :

   "friendsofsymfony/rest-bundle": "0.13.*@dev",
   "jms/serializer-bundle": "0.12.*@dev",

我正在关注 Automatic route generation: single RESTful controller (for simple resources)

配置:

fos_rest:
    format_listener: true
    routing_loader:
        default_format: json
    view:
        view_response_listener: 'force'
    serializer:
        serialize_null: true

sensio_framework_extra:
    view:    { annotations: false }
    router:  { annotations: true }

路由:

sectors:
    type: rest
    prefix: /{v}
    resource: JJ\MainBundle\Controller\SectorsController

Controller :

/**
 * @RouteResource("Sector")
 */
class SectorsController extends Controller
...
    public function cgetAction()
    {
        return $this->getSectorIndustryRepo()->findAll();
    }

Answer 1

我设法通过将监听器显式设置为 false 来解决此问题:

fos_rest:
    format_listener: false

编辑

这也有效:

fos_rest:
    format_listener:
        prefer_extension: false
        default_priorities:
            - json
