Symfony - 从控制器

标签: php symfony code-injection

我正在使用symfony 3并尝试访问我在

中声明的类
  

的src /的appbundle /服务/ ApiEngine.php

namespace AppBundle\Service;


use DateTime;

class ApiEngine {

    private $api_handler;

    public function __construct($username, bool $repos) {
        $client = new \GuzzleHttp\Client();
        $request = 'https://api.github.com/users/' . $username;
        $request .= ($repos) ?  '/repos' : "";
        $res = $client->request('GET', $request);

        $this->api_handler = json_decode($res->getBody()->getContents(), true);
    }

    public function getProfileData() {
        return [ /*some data*/ ];
    }
}

我在

中声明了这个文件
  

配置/ service.yml

service:
  *
  *
  *
  api:
      class: AppBundle\Service\ApiEngine
      arguments: ["@username", "@repos"]

在控制器中我试图使用一些像这样的ApiEngine方法:

  

的src /的appbundle /控制器/ GitApiController.php

namespace AppBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class GitApiController extends Controller {

    /**
     * @Route("/{username}", name ="gitapi", defaults={"username": "symfony"})
     */
    public function gitApiAction($username) {
        $api = $this->get('api')->__construct($username, false)->getProfileData();

        return $this->render('gitapi/index.html.twig', $api);
    } }

但它给了我这个错误:

  

(1/1)ServiceNotFoundException服务“api”依赖于a   不存在的服务“用户名”。

我建议你改变你的课程,例如:

private function __construct($username, bool $repos) {
        $client = new \GuzzleHttp\Client();
        $request = 'https://api.github.com/users/' . $username;
        $request .= ($repos) ?  '/repos' : "";
        $res = $client->request('GET', $request);

        $this->api_handler = json_decode($res->getBody()->getContents(), true);
    }

public static function createApiEngine($username, bool $repos) 
{
    return new self($username, $bool);
}

在控制器内部后,您可以执行此操作:

$api = ApiEngine::createApiEngine($username, false);
$api->getProfileData();

在您的控制器中,您需要为use插入ApiEngine,在此用例中您不需要依赖注入,因此请在services.yml删除参数中
