Php Symfony restfull json分页

我需要创建带分页的api方法，并创建操作和服务，但我有响应：

 {
 "self_page": "\\/app_dev.php\\/projects?count=10&page=1&sort_by=created&sort_order=DESC",
 "next_page": "\\/app_dev.php\\/projects?count=10&page=2",
 "prev_page": "\\/app_dev.php\\/projects?count=10&page=0",
 "first_page": "\\/app_dev.php\\/projects?count=10&page=1",
 "last_page": "\\/app_dev.php\\/projects?count=10&page=10",
 "projects": [
  {

所有数据，我在数据库中有100行，然后在标题中正确显示，但为什么不进行分页呢？我必须得到10行，但我有所有（100个项目）我创建了createQueryBuilder，如果我在$queryBuilder中调试，我有正确的参数（coutn 4->I have 4 project），但这个参数在分页中如何使用

  * RestView()
 *
 * @QueryParam(name="status", strict=true, requirements="[a-z]+", description="status of project", nullable=true)
 * @QueryParam(name="count", requirements="\d+", default="10", description="Count project at one page")
 * @QueryParam(name="page", requirements="\d+", default="1", description="Number of page to be shown")
 * @QueryParam(name="sort_by", strict=true, requirements="^[a-zA-Z]+", default="created", description="Sort by", nullable=true)
 * @QueryParam(name="sort_order", strict=true, requirements="^[a-zA-Z]+", default="DESC", description="Sort order", nullable=true)
 *
 * @param  ParamFetcher $paramFetcher
 * @return View
 *
 * @throws NotFoundHttpException when not exist

public function getProjectsAction(ParamFetcher $paramFetcher)
{
    $manager = $this->getDoctrine()->getManager();

    $repository = $manager->getRepository('ArtelProfileBundle:Project');

        if (!$paramFetcher->get('status')) {
        $queryBuilder = $repository->createQueryBuilder('project')
            ->where('project.currentStatus != :identifier1','project.currentStatus != :identifier2')
            ->setParameter('identifier1', 'fail')
            ->setParameter('identifier2', 'rejected')
            ->orderBy('project.'.$paramFetcher->get('sort_by'), $paramFetcher->get('sort_order'))
            ->setFirstResult($paramFetcher->get('count') * ($paramFetcher->get('page') - 1))
            ->setMaxResults($paramFetcher->get('count'))
            ->getQuery()
            ->getResult()
        ;
    } else {
        $queryBuilder = $repository->createQueryBuilder('project')
            ->where('project.currentStatus = :identifier')
            ->setParameter('identifier', $paramFetcher->get('status'))
            ->orderBy('project.'.$paramFetcher->get('sort_by'), $paramFetcher->get('sort_order'))
            ->setFirstResult($paramFetcher->get('count') * ($paramFetcher->get('page') - 1))
            ->setMaxResults($paramFetcher->get('count'))
            ->getQuery()
            ->getResult()
        ;
    }

    $projectAll = $repository->findAll();
    $paginator = $this->get('paginator');

    $pagination = $paginator->getPaginated(
        $paramFetcher->get('count'),
        $paramFetcher->get('page'),
        $paramFetcher->get('sort_by'),
        $paramFetcher->get('sort_order'),
        $projectAll
    );

    $projectResponse = new ProjectResponse();

    $projectResponse->setProjects($projectAll);
    $projectResponse->setSelfPage($pagination->getSelfPage());
    $projectResponse->setNextPage($pagination->getNextPage());
    $projectResponse->setPrevPage($pagination->getPrevPage());
    $projectResponse->setFirstPage($pagination->getFirstPage());
    $projectResponse->setLastPage($pagination->getLastPage());

    return $projectResponse;
}

并创建分页服务：

class PaginatorService

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

public function getPaginated(
   $count,
   $pages,
   $sortBy,
   $sortOrder,
   $projectAll
) {
    $this->count = $count;
    $this->pages = $pages;
    $this->sortBy = $sortBy;
    $this->sortOrder = $sortOrder;
    $this->maxPerPage = 10;
    $this->projectAll = count($projectAll);

    $dreamsResponse = new ProjectResponse();

    $dreamsResponse->setSelfPage($this->getSelfPage());
    $dreamsResponse->setNextPage($this->getNextPage());
    $dreamsResponse->setPrevPage($this->getPrevPage());
    $dreamsResponse->setFirstPage($this->getFirstPage());
    $dreamsResponse->setLastPage($this->getLastPage());

    return $dreamsResponse;
}

private function calculateNbPages()
{
    return (int) ceil($this->projectAll / (int) $this->count);
}

/**

    return (int) $this->pages < $this->getNbPages();
}

private function getNbPages()
{
    $nbPages = $this->calculateNbPages();

    if ($nbPages == 0) {
        return $this->minimumNbPages();
    }

    return $nbPages;
}

    return 1;
}

我解决了这个问题，我需要创建queryBuilder并使用sort\u order sort\u by和count，然后在$projectResponse->setProjects（$queryBuilder）中发布queryBuilder

因为你正在获取所有项目<代码>$projectAll=$repository->findAll（）在这种情况下，要使输出与计数一样多？然后开始下一个计数如果我尝试get/projects.json？count=2&page=6&sort_by=createdAt&sort_order=ASCфцц我仍然得到所有项目，但我必须在第6页-id 11 id 12中得到2个项目。怎么做对了？我更新我的问题是因为你获取了所有的项目<代码>$projectAll=$repository->findAll（）在这种情况下，要使输出与计数一样多？然后开始下一个计数如果我尝试get/projects.json？count=2&page=6&sort_by=createdAt&sort_order=ASCфцц我仍然得到所有项目，但我必须在第6页-id 11 id 12中得到2个项目。怎么做对了？我更新了我的问题
