Symfony-将json反序列化为实体数组 [英] Symfony - Deserialize json to an array of entities

问题描述

我有一个通过调用get API收到的json对象.我进行此调用以接收对象列表.这是一个帖子列表...所以我有一系列的Post Objects.

I have a json object that I received by making a get API call. I make this call to receive a list of objects. It's a list of post... So I have an array of Post Objects.

这里是输出:

{
    "total":2,
    "data":[
      {
        "id":2,
        "user":{
          "id":1,
          "username":"sandro.tchikovani"             
        },
        "description":"cool",
        "nb_comments":0,
        "nb_likes":0,
        "date_creation":"2014-04-13T20:07:34-0700"
      },
      {
        "id":1,
        "user":{
           "id":1,
           "username":"sandro.tchikovani",
         },
        "description":"Premier pooooste #lol",
        "nb_comments":0,
        "nb_likes":0,
        "date_creation":"2014-04-13T15:15:35-0700"
      }
    ]
 }

我想反序列化数据部分... 问题是Symfony中的序列化器给我一个错误...

I would like to deserialize the data part... The problem is that the Serializer in Symfony gives me an error ...

我遇到的错误:

Class array<Moodress\Bundle\PosteBundle\Entity\Poste> does not exist

我如何反序列化:

$lastPosts = $serializer->deserialize($data['data'], 'array<Moodress\Bundle\PosteBundle\Entity\Poste>', 'json');

我如何反序列化数据数组...要有一个Postes数组.我想给出我的观点.twig一个数组Poste ...当我反序列化时我确实精确了类型...所以我找不到问题所在...

How can I deserialze the data array... To have an array of Postes. I want to give to my view .twig an array Poste... I did precise the type when I deserialize... So I can't find what is the problem...

谢谢.

推荐答案

错误非常明显.您的字符串与任何现有的类都不匹配.

The error is pretty clear. Your string does not match any existant class.

官方文档中的示例显示:

$person = $serializer->deserialize($data,'Acme\Person','xml');

您的情况应该更像是:

$person = $serializer->deserialize($data['data'],'Moodress\Bundle\PosteBundle\Entity\Poste','json');

更新:

好吧.

首先，您的json文件似乎无效(使用 http://jsonlint.com/进行测试它).小心点.

First, your json file does not seem to be valid (use http://jsonlint.com/ to test it). Be careful of that.

第二，您将必须使用以下数组来获取json作为数组

Second, you will have to fetch your json as an array with

$data = json_decode($yourJsonFile, true);

然后您可以使用

foreach($data['data'] as $result)
{
    /* Here you can hydrate your object manually like:
    $person = new Person();
    $person->setId($user['id']);
    $person->setDescription($user['description']);

    Or you can use a denormalizer. */
}
