我使用get动作为Movie对象创建了一个休息控制器。

我的数据库管理员使用id:3一部电影。

enter image description here

当我尝试访问localhost:8000/api/movie/3或其他任何想法时,它会直接回到我来自的页面,只有一点没有内容响应。

[Tue May 29 16:06:42 2018] 127.0.0.1:61540 [204]: /api/movie/3

我有以下配置:

services.yaml

services:
    ...
    sensio_framework_extra.view.listener:
        alias: Sensio\Bundle\FrameworkExtraBundle\EventListener\TemplateListener
    ...

路由/ rest.yaml

movies:
    type:     rest
    resource: App\Controller\MovieController
    prefix: /api

包/ fos_rest.yaml

fos_rest:
    param_fetcher_listener:  true
    allowed_methods_listener:  true
    routing_loader:
        include_format: false
    view:
        view_response_listener:  'force'
    format_listener:
        rules:
            - { path: '^/api', priorities: ['json'], fallback_format: 'json' }
    zone:
        - { path: ^/api/* }

包/ framework.yaml:

framework:
    ...
    templating: { engines: ['twig'] }

以下文件:

控制器/ MovieController.php

<?php

namespace App\Controller;

use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\Routing\ClassResourceInterface;
use FOS\RestBundle\Controller\FOSRestController;

/**
* @Rest\RouteResource("Movie", pluralize=false)
*/
class MovieController extends FOSRestController implements ClassResourceInterface {

    /**
     * @Rest\View()
     * @Rest\Get("/movie/{id}")
     */
    public function getAction(string $id) {}

}

实体/ Movie.php

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Repository\MovieRepository")
 */
class Movie {
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=32)
     */
    private $title;

    public function __construct($title) {
        $this->title = $title;
    }

    ...
}

调试路由器给了我这个结果:

$ bin/console debug:router | grep movie
  get_movie                     GET        ANY      ANY    /api/movie/{id}

[更新]

由于之前的错误配置,我遇到了错误:

1

  

警告:ReflectionObject :: __ construct()期望参数1为object,给定

为null

2

  

必须在FOS \ RestBundle \ View \ ViewHandler中注入Symfony \ Bundle \ FrameworkBundle \ Templating \ EngineInterface&gt;的实例才能呈现模板。

3

  

类型错误:参数2传递给Twig_Environment :: render()   必须是数组类型

4

  

命名空间“FOSRest”没有注册路径。

5

  

SyntaxError:JSON.parse:JSON数据第1行第1列的意外字符

我必须编辑MovieController以返回对象或返回异常。

MovieController.php

<?php

namespace App\Controller;

use App\Repository\MovieRepository;
use Doctrine\ORM\EntityManagerInterface;
use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\Routing\ClassResourceInterface;
use FOS\RestBundle\Controller\FOSRestController;


/**
* @Rest\RouteResource("Movie", pluralize=false)
*/
class MovieController extends FOSRestController implements ClassResourceInterface {

    /**
     * @var EntityManagerInterface
     */
    private $entityManager;

    /**
     * @var MovieRepository
     */
    private $movieRepository;

    public function __construct(
        EntityManagerInterface $entityManager,
        MovieRepository $movieRepository
    ) {
        $this->entityManager       = $entityManager;
        $this->movieRepository     = $movieRepository;
    }

    public function getAction(string $id) {
        $movie = $this->movieRepository->find($id);

        if($movie === null) {
            throw new NotFoundHttpException();
        }

        return $this->view($movie);
    }
}

您应该在视图注释参数中添加populateDefaultVars,如下所示:

/ ** * * @rest \ View(populateDefaultVars = false) * /
