评论可以用于json吗?

我可以在json文件里使用注释吗? 如果是的话,怎么写?

当前回答

(hack)是一个很好的解决办法(hack),这是有效的json,但并非在所有情况下都能奏效(见下文的评论)。

{
  "param" : "This is the comment place",
  "param" : "This is value place",
}

所以json会理解这一点:

{
  "param" : "This is value place",
}

特意从json中删除了评论。

我删除了Json的评论, 是因为我看到人们用他们来维持分析指令, 这种做法会破坏互操作性。我知道缺乏评论会让一些人感到悲哀, 但不应该。假设你正在使用 Json 来保存配置文件, 您想要做笔记。继续, 插入所有您喜欢的评论。然后通过 jsmin 插入它, 然后把它交给 Jsmin , 然后再交给 Jsson 牧师。

考虑使用 aml 。它几乎是 json 的超级集( 几乎所有有效的json 都是有效的 aml ) , 它允许评论。

json不允许评论本身。推理是完全愚蠢的, 因为你可以使用json自己来创造评论, 这完全排除了推理, 并且毫无理由地在完全相同的结果和潜在问题上加载采集数据空间, 比如: 带有评论的json文件。

如果您试图在(使用 / 或 / * * * 或 ) 中发表评论, 那么某些剖析器将会失败, 因为严格来说这不在json 的规格之内。所以您不应该这样做。

例如,在这里,我的图像操作系统保存了图像标记和一些基本格式化(注释)信息(底部):

json 曾经支持评论,但被滥用,从标准中删除。

是从杰森的创造者那里降示的:

我删除了Json的评论, 是因为我看到有人利用他们来维持分解指令, 这种做法会破坏互操作性。我知道,

json官方网站位于json.org.json被国际电子公司界定为一项标准。总是有请愿程序要求修订标准。出于若干原因,说明不可能加入json标准。

json 被设计成一种容易逆向工程(人类割除)的 xml 替代物。它被简化到无需附加说明的地步。它甚至不是标记语言。目标是稳定性和互操作性。

任何理解目标方向“has-a”关系的人,都能理解任何json结构,这就是整个点。这只是一个带有节点标记(键/价值对)的定向环绕图(dag),这是一个近乎普遍的数据结构。

仅此说明要求的可能是“//这些是标记”。关键名称可以按要求提供信息,允许任意的语义性。

任何平台都可以用几行代码分析json。 xml 需要复杂的 oo 图书馆, 在许多平台上都是不可行的。

说明只会降低json 的互操作性。没有什么可以补充的了, 除非您真正需要的是一个标记语言( xml) , 并且不关心您持续的数据是否容易解析。

但Json的创造者也指出, js一直支持评论:

插入所有您喜欢的评论。然后通过 Jsmin 管道, 然后再把它交给您的 Json 采摘师。
