JSON.parse应该是递归的吗？

Question

我正在解析一个像这样的json字符串:

ring = JSON.parse(response);

现在,ring是一个对象,但是ring.stones只是一个字符串,它应该也是一个对象.

如果我打电话:

ring.stones = JSON.parse(ring.stones);

它现在是正确的对象.

我不知道这是否是正确的行为,或者我是否有某个问题阻止其递归解析？如果它应该递归解析,是否有任何已知的问题会阻止它？

以下是解析之前的完整响应:

更新2

基于mikerobi的回答,我能够弄清楚发生了什么:

这是我编码的地方:

$row = $sth->fetch(PDO::FETCH_ASSOC);

$row['stones'] = getStones($ring_id);
$row['images'] = getRingVariations($ring_id);

return json_encode($row);

但功能getStones和getRingVariations返回json_encode'字符串.我需要更改它们以返回纯字符串.

Answer 1

您的JSON结构是错误的,它将石头包裹在引号中,将其转换为字符串.

你的JSON看起来像:

{
    stones: "[{\"stone_id":\"27\"},{\"stone_id\":\"27\"}]"
}

它应该看起来像:

{
    stones: [{"stone_id": 27},{"stone_id": 27}]
}

编辑

看来你正在将所有值转换为字符串,包括数字,我更新了我的例子以反映这一点.

另外,我猜输出你正在编写自己的代码来序列化JSON,我强烈建议使用现有的库.
