控制器必须 return 一个响应（给定 1 个）。 500 内部服务器错误 - LogicException
The controller must return a response (1 given). 500 Internal Server Error - LogicException
我从以下控制器代码开始
<?php
namespace AppBundle\Controller;
use AppBundle\Entity\events;
//use AppBundle\Entity\eventtype;
use AppBundle\Entity\users;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

use Symfony\Component\Form\Extension\Core\Type\ChoiceType;
class DefaultController extends Controller {
/**
* @Route("/home", name="homepage")
*/
public function indexAction(Request $request) {
$events = new events();
$form = $this->createFormBuilder($events)
->add('eT1', ChoiceType::class, array(
'choices' => array(
'Poker' => 1,
'Chess' => 2,
'Cricket' => 3,
'Marbles' => 4,
'Football' => 5,
),
'choices_as_values' => true,
'expanded' => true,
'multiple' => false,
'label' => 'Choose After Breakfast Event',
))
->add('eT2', ChoiceType::class, array(
'choices' => array(
'Poker' => 1,
'Chess' => 2,
'Cricket' => 3,
'Marbles' => 4,
'Football' => 5,
),
'choices_as_values' => true,

))
->add('save', SubmitType::class, array('label' => 'Submit'))
->getForm();
if ($request->isMethod('POST')) {
$form->submit($request);
$formData = $form->getData();
//check to see if the after breakfast event (eT1) is full (ie.has reached the maxlimit)
//for now the maxLimit is set to 4
$ET1 = $formData->getET1();
$repository = $this->getDoctrine()->getRepository('AppBundle:events');
$query1 = $repository->createQueryBuilder('p')
->select('count(p)')
->where('p.eT1 = :eT1')
->setParameter('eT1', $ET1)
->getQuery();
$a = $query1->getSingleScalarResult();
if ($a >= $maxLimit=4) {
echo 'choose another event, this one is full';
}
else{
return $ET1;
}
//check to see if the after snacks event (eT2) is full (ie.has reached the maxlimit)
//for now the maxLimit is set to 4
$ET2 = $formData->getET2();
$query2 = $repository->createQueryBuilder('p')
->select('count(p)')
->where('p.eT2 = :eT2')
->setParameter('eT2', $ET2)
->getQuery();
$b = $query2->getSingleScalarResult();
if ($b >= $maxLimit=4) {
echo 'choose another event, this one is full';
}
else{
return $ET2;
}
//get the user_id of the logged in user
$user = $this->container->get('security.context')->getToken()->getUser();
$events->setUser($user);
$x = $events->getUser()->getID();
if ($form->isValid()) {
//check if the user has already registered or not
$y = $repository->findOneBy(array('user' => $x));
// If the user is registering for the first time (execute the insert query)
if (!$y) {
$em = $this->getDoctrine()->getManager();
$em->persist($events);
$em->flush();
return $this->redirectToRoute('homepage');
}
//If the user has registered already and want change his registered events (execute the update query)
else {
$formData = $form->getData();
$ET1 = $formData->getET1();
$ET2 = $formData->getET2();
$events->setET1($ET1);
$events->setET2($ET2);
$em = $this->getDoctrine()->getManager();
$em->persist($events);
$em->flush();
return $this->redirectToRoute('homepage');
}
}
}
return $this->render('default/index.html.twig', array(
'form' => $form->createView(),
));
}
}
但后来我修改了代码，为已经注册的用户和第一次注册的用户显示不同的页面。
以下代码给出错误 - 控制器必须 return 响应（给定 1）。 500 内部服务器错误 - LogicException
我的猜测是错误在于语句 return $ET1; 和 return $ET2;
以下是我找不到答案的问题：
1. 错误原因 - 控制器必须 return 响应（给出 1）。 500 内部服务器错误 - LogicException
2. 我必须为新用户和已注册用户重复相同的代码两次。有解决办法吗？
3. 如何从 config.yml 文件中为不同的事件（例如扑克=12、国际象棋=4、板球=10 等）设置不同的 $maxLimit 参数值？
这里是修改后的控制器代码

您的控制器不可读...您可能希望将业务代码放在服务中，将 formTypes 放在专用 类 中，将查询放在存储库 类.
中
我认为你没有进入 if(!$y ) 条件
放在最后：
return $this->render('default/index.html.twig'));
像 $ET2 和 $ET2 这样的元素不是响应而是 formData 数组，Symfony 希望你 return 响应所以确保将它渲染到视图中，或者可能 return 通过新的 JsonResponse 对象将其作为数据？
您还可以添加 @Template annotation 以便能够 return 数据。该注释告诉 Symfony 应该根据 returned 数据呈现模板。
回答你的第一个问题：控制器必须总是 return 类型响应的对象，如果它不能 return 响应对象那么它必须通过执行内部子请求转发控制到执行 return 响应对象的控制器。在 symfony 中，twig 模板用于向用户显示输出，使用
return $this->render('navigation/homepage.html.twig', array('et1' => $et1, 'et2' => $et2));
将使两个变量 et1 和 et2 在 homepage.html.twig 模板中可用。
回答第二个问题：通过 $this->getUser() 获取当前登录用户，这是 security.context 令牌 link
的快捷方式
我在这里猜测，你试图检查 userId 是否与 'events' 对象的 userId 匹配，你认为它是一个 returning 用户，如果在此前提下，它不是新用户
$user = $this->getUser()->getUserId();
$event = $this->getDoctrine()->getRepository('AppBundle:events')->findOneBy(array('user' => $this->getUser()->getUserId() ));
if($event instanceof events){ //events refers to 'events' entity
// code to handle returning user
}
第三个问题的答案：避免使用全局变量，通过使用 config.yml 存储 maxValue，您使 maxValue 可用于整个项目。您可以更改代码中的内容以不使用 golbal 变量，但只是为了回答问题
将您的全局变量存储在 parameters.yml 而不是 config.yml 中只是为了让事情易于理解，做这样的事情 link
parameters:
cricketMaxLimit: 10
用$cricMaxLimit = $this->container->getParameter('cricketMaxLimit');
检索
旁注：像 if ($a >= $maxLimit = 4) 这样的东西在这个世界上根本不应该存在，做 if ($a >= 4)

您的控制器不可读...您可能希望将业务代码放在服务中，将 formTypes 放在专用 类 中，将查询放在存储库 类.
中我认为你没有进入 if(!$y ) 条件
放在最后：
return $this->render('default/index.html.twig'));
像 $ET2 和 $ET2 这样的元素不是响应而是 formData 数组，Symfony 希望你 return 响应所以确保将它渲染到视图中，或者可能 return 通过新的 JsonResponse 对象将其作为数据？
您还可以添加 @Template annotation 以便能够 return 数据。该注释告诉 Symfony 应该根据 returned 数据呈现模板。
回答你的第一个问题：控制器必须总是 return 类型响应的对象，如果它不能 return 响应对象那么它必须通过执行内部子请求转发控制到执行 return 响应对象的控制器。在 symfony 中，twig 模板用于向用户显示输出，使用
return $this->render('navigation/homepage.html.twig', array('et1' => $et1, 'et2' => $et2));
将使两个变量 et1 和 et2 在 homepage.html.twig 模板中可用。
回答第二个问题：通过 $this->getUser() 获取当前登录用户，这是 security.context 令牌 link
我在这里猜测，你试图检查 userId 是否与 'events' 对象的 userId 匹配，你认为它是一个 returning 用户，如果在此前提下，它不是新用户
$user = $this->getUser()->getUserId();
$event = $this->getDoctrine()->getRepository('AppBundle:events')->findOneBy(array('user' => $this->getUser()->getUserId() ));
if($event instanceof events){ //events refers to 'events' entity
// code to handle returning user
}
第三个问题的答案：避免使用全局变量，通过使用 config.yml 存储 maxValue，您使 maxValue 可用于整个项目。您可以更改代码中的内容以不使用 golbal 变量，但只是为了回答问题
将您的全局变量存储在 parameters.yml 而不是 config.yml 中只是为了让事情易于理解，做这样的事情 link
parameters:
cricketMaxLimit: 10
用$cricMaxLimit = $this->container->getParameter('cricketMaxLimit');
旁注：像 if ($a >= $maxLimit = 4) 这样的东西在这个世界上根本不应该存在，做 if ($a >= 4)
