REST 中的 JSON 输出格式

Question

我有一个类似的结构，由 REST Api 返回：

{
    "id": 1,
    "type": "A",
    "name": "blah, blah"
}

自然输出样本如下：

[
    {
        "id": 1,
        "type": "A",
        "name": "blah, blah"
    },
    {
        "id": 1,
        "type": "A",
        "name": "blah, blah"
    },
    {
        "id": 1,
        "type": "B",
        "name": "blah, blah"
    },
    {
        "id": 1,
        "type": "C",
        "name": "blah, blah"
    }
]

为方便起见，我宁愿以分组格式（围绕“类型”）输出，如下所示：

{
    "A": [
        {
            "id": 1,
            "name": "blah, blah"
        },
        {
            "id": 1,
            "name": "blah, blah"
        }
    ],
    "B": [
        {
            "id": 1,
            "type": "B",
            "name": "blah, blah"
        }
    ],
    "C": [
        {
            "id": 1,
            "type": "C",
            "name": "blah, blah"
        }
    ]
}

在输入参数方面是否有一种通用的、REST 友好的方式来执行此操作？

我有一个参数“response_mode”，它可以是 FLAT 或 GROUPED，但不确定从 RESTful 角度来看是否可以。

在php中我会这样排序：

<?php

$response = '[
    {
        "id": 1,
        "type": "A",
        "name": "blah, blah"
    },
    {
        "id": 1,
        "type": "A",
        "name": "blah, blah"
    },
    {
        "id": 1,
        "type": "B",
        "name": "blah, blah"
    },
    {
        "id": 1,
        "type": "C",
        "name": "blah, blah"
    }
]';

$jsonDecoded = json_decode($response);
$newResponse = array();

foreach($jsonDecoded as $jd) {
   $newResponse[$jd->type][] = array(
      "id"   => $jd->id,
      "type" => $jd->type,
      "name" => $jd->name
   );
}

echo json_encode($newResponse);
