php - FOSRestBundle 无法获取参数 getter

Question

我正在尝试让我的 Controller 与参数 getter 一起工作。我做了文档中指定的所有说明。所以我有:配置fos_rest.yml:

fos_rest:
  param_fetcher_listener: 'force'
  view:
      formats:
          json: true
          xml: false
          rss: false
      mime_types:
          json: ['application/json', 'application/x-json', 'application/vnd.example-com.foo+json']
          png: 'image/png'
      failed_validation: HTTP_BAD_REQUEST
      default_engine: twig
      view_response_listener: 'force'
  format_listener:
      default_priorities:
          - json
  routing_loader:
      default_format: json

sensio_framework_extra: 查看:{注解:假} 路由器:{注解:真}

还有我的 Controller

<?php

namespace Push\PointsBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Nelmio\ApiDocBundle\Annotation\ApiDoc;
use FOS\RestBundle\View\View;
use FOS\RestBundle\Controller\Annotations\QueryParam;
use FOS\RestBundle\Request\ParamFetcherInterface;
use FOS\RestBundle\Controller\Annotations\RequestParam;
use FOS\RestBundle\Request\ParamFetcher;

class RestController extends Controller
{
    /**
     * @QueryParam(name="latitude", requirements="[0-9.]+", default="0", description="")
     * @ApiDoc()
     */
    public function checkPointsAction(ParamFetcher $params)
    {
        $view = new View();
        return $this->get('fos_rest.view_handler')->handle($view);
    }
}

当我调用方法时，我得到:

Controller "Push\PointsBundle\Controller\RestController::checkPointsAction()" requires that you provide a value for the "$params" argument (because there is no default value or because there is a non optional argument after this one).

我做错了什么或错过了什么？谢谢。

Answer 1

我经常遇到 FOSRestBundle 和过时缓存的问题。如果我更改注释，它有时不会刷新。首先，尝试删除 app/cache 目录的内容 (rm -rf app/cache/*)。

我没有检查参数是否通过类型或名称映射到方法参数。如果它晚于你的参数应该被称为 $paramFetcher(不是 $params):

public function checkPointsAction(ParamFetcher $paramFetcher) { }

编辑:您是否启用了参数 getter 监听器？

fos_rest:
    param_fetcher_listener: true
