Symfony2，如何将数组作为参数传递给控制器操作？

如何使用Symfony 2将数组作为参数传递给控制器操作？请您写一个例子，如何定义路由，其中包含未知长度数组作为参数。例如url：其中标记的数量从0到100不等。 也是此路由的示例控制器，其中操作返回标记数组的值

使用以下编码（请参见下面的routing.yml和controller.php），我得到了错误：

Catchable Fatal Error: Argument 3 passed to Symfony\Component\Routing\Route::__construct() must be of the type array, string given, called in C:\Bitnami\wampstack-5.5.30-0\sym_prog\dctr\vendor\symfony\symfony\src\Symfony\Component\Routing\Loader\YamlFileLoader.php on line 147 and defined in C:\Bitnami\wampstack-5.5.30-0\sym_prog\dctr\app/config\routing.yml (which is being imported from "C:\Bitnami\wampstack-5.5.30-0\sym_prog\dctr\app/config/routing_dev.yml").

以下是迄今为止我尝试过的路由和控制器文件的不同组合：

嗯，经过一些尝试，我找到了下一个解决方案

您可以将布线模式更改为此（标记：“[a-zA-Z0-9/]+”）：

然后可以通过，但仍然需要explode（）来获取参数。

最后，我找到了答案。与其传递数组，不如将其编码为json字符串。下面是一个例子：

C:\Bitnami\wampstack-5.5.30-0\sym\u prog\proj3\u 27\src\MeetingBundle\Controller\UserController.php

//http://localhost:8000/blog/post/?tags=[tag1,tag2] .
/**

 * @Template()
 */
public function list_postsByTagAction($tags){
    var_dump($tags);
    return array('posts'=>['post1','post2']);
}

//url http://localhost:8000/blog/post/?tags=[tag1,tag2]
/**
 * @Route("/posts/{tags}")
 * @Method("GET")
 * @Template()
 */
public function list_postsByTagActionQ1(Request $request){
    $tags=$request->query->get('tags'); // get a $_GET parameter       
    var_dump($tags);
    return array('posts'=>['post1','post2']);
} 

//url http://localhost:8000/blog/post/?tags=[tag1,tag2]
/**
 * @Route("/posts/{tags}")
 * @Method("GET")
 * @Template()
 */
public function list_postsByTagActionQ3(Request $request, $tags){           
    var_dump($tags);
    return array('posts'=>['post1','post2']);
}

//url http://localhost:8000/blog/post/?tags=[tag1,tag2]
 public function list_postsByTagActionQ(Request $request){
    $tags=$request->query->get('tags'); // get a $_GET parameter
      var_dump($tags);
}

..
    /**
     * Displays a form to edit an existing User entity.
     *
     * @Route("/{id}/edit", name="user_edit")
     * @Method({"GET", "POST"})
     */
    public function editAction(Request $request, User $user)
    {
..
 $bredArr=array( 'user_edit' => array (  'id'=>$user->getId() ) );
..
        return $this->render( 'MeetingBundle::user/edit.html.twig', array(
            'user' => $user,
            'edit_form' => $editForm->createView(),
            'image_form' => $imageForm->createView(),
            'delete_form' => $deleteForm->createView(),
            'bredArr'=>$bredArr,
        ));

$bredArr是在

User

controller

edit\u User

操作中创建的变量。它用作路径变量

image\u deletenf

中的参数。我不知道如何将其作为数组传递，但如果编码为Json字符串，它就可以工作。我需要

image\u deletenf

操作，以便能够重定向到我想要的路径。我可以从用户、事件和注释实体中删除图像，因此在删除后，我希望返回到用户、事件或注释，而不是默认的图像索引，因此我需要此

$bredArr

以使用正确的参数指向正确的实体

看这个例子，我需要routing.yml和controller.phpvalues，而不是我问题表单中的参数。我已经删除了所有要求，但我得到了相同的错误。您的文件是否保存在utf-8中？可能在“需求”键后有不可见字符。。像断线？尝试删除需求并从头开始重新编写。版本r2和版本r3没有requirements@olga所以，您总是会得到错误“可捕获致命错误：参数3传递给Symfony\Component\Routing\Route:：\uu construct（）…”？
