您可以使用JSON-LD (JSON-LD)和schema.org 注释用于正确写入备注:

{
    "https://schema.org/comment": "this is a comment"
}

我刚刚发现"- - - - - - - -".

“JSON的简短评论,它允许你在JSON的文件中使用评论!”

{
    // Rainbows
    "unicorn": /* ❤ */ "cake"
}

纯粹的答案是否 无.

但有些编辑和平台利用变通办法向JSON提供评论。

1今天,大多数编辑都有内在的选择和扩展,以补充对JSON文件的评论。 (例如: - VS 代码还有一个带有评论的JSON。(jsonc) mode《VS法典》也有很好的展期)

VsCode 中激活 jsonc 模式的链接

2一些平台为补充评论(简简json)提供了内在途径。 (例如:- 在消防基地,我可以评论firebase.json暂时没有问题。

    {
    "hosting": {
        "headers": [
            /*{
              "source": "*.html",
              "headers": [
                {
                  "key": "Content-Security-Policy",
                  "value": "default-src 'self' ..."
                }
              ]
            },*/
        ]
      }
    }

3。在您自己的 JSON 解析方法中,您可以设置一个预定义的密钥名称作为注释。

包括:-

     {
        "comment" : "This is a comment",
        "//" :  "This also comment",
        "name" : "This is a real value"
     }

还有其他图书馆与JSON兼容,

其中一个显著的例子是:“Hashcorp语言”(HCL)” (HCL)由那些制造流浪者、包装者、领事和保险库的人共同撰写。

JSON本身不允许评论。 推理是完全愚蠢的, 因为你可以使用JSON。本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身 本身提出评论,完全排除推理,和在完全没有正当理由的情况下装入解析器数据空间精确同一结果和潜在问题,如:JSON档案,附有评论。

如果您试图在(使用)//或/* */或#举例说 ) , 那么有些分析师会失败, 因为这严格地说不在JSON 的规格之内。 所以您应该从未这样做。

您可以通过正则表达式使用简单的预处理。例如,以下函数将解码在 PHP 中评论 JSON:

function json_decode_commented ($data, $objectsAsArrays = false, $maxDepth = 512, $opts = 0) {
  $data = preg_replace('~
    (" (?:[^"\\\\] | \\\\\\\\ | \\\\")*+ ") | \# [^\v]*+ | // [^\v]*+ | /\* .*? \*/
  ~xs', '$1', $data);

  return json_decode($data, $objectsAsArrays, $maxDepth, $opts);
}

它支持所有PHP风格的评论: / *, #, / /。 字符串的字句保留不变 。
