我喜欢 @eli ' s 方法, 超过 30 个答案, 但没有人提到列表( array) 。 所以使用 @eli ' s 方法, 我们可以做一些类似的事情:

"part_of_speech": {
  "__comment": [
    "@param {String} type - the following types can be used: ",
      "NOUN, VERB, ADVERB, ADJECTIVE, PRONOUN, PREPOSITION",
      "CONJUNCTION, INTERJECTION, NUMERAL, PARTICLE, PHRASE",
    "@param {String} type_free_form - is optional, can be empty string",
    "@param {String} description - is optional, can be empty string",
    "@param {String} source - is optional, can be empty string"
  ],
  "type": "NOUN",
  "type_free_form": "noun",
  "description": "",
  "source": "https://google.com",
  "noun_class": {
    "__comment": [
      "@param {String} noun_class - the following types can be used: ",
        "1_class, 2_class, 3_class, 4_class, 5_class, 6_class"
    ],
    "noun_class": "4_class"
  }
}

正如许多答复已经指出的,JSON在本地没有评论。当然,有时你还是想要评论。Python 符号,两个方法commentjson (#和//仅用于 Python 2 的)或json_tricks (#或//Python 2 和 Python 3 的 Python 2 和 Python 3, 具有其他几个特点。json_tricks.

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。

如果您正在使用 PHP, 您可以使用此函数搜索并删除 JSON 字符串中的 / / / * 键入批注, 然后将其解析成对象/ 数组 :

function json_clean_decode($json, $assoc = true, $depth = 512, $options = 0) {
       // search and remove comments like /* */ and //
       $json = preg_replace("#(/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/)|([\s\t]//.*)|(^//.*)#", '', $json);

       if(version_compare(phpversion(), '5.4.0', '>=')) {
           $json = json_decode($json, $assoc, $depth, $options);
       }
       elseif(version_compare(phpversion(), '5.3.0', '>=')) {
           $json = json_decode($json, $assoc, $depth);
       }
       else {
           $json = json_decode($json, $assoc);
       }

       return $json;
   }

希望这有帮助!

在JSON的输出之前,我需要将评论用于调试目的。所以我把调试信息放进HTTP 信头为了避免客户被打破:

header("My-Json-Comment: Yes, I know it's a workaround ;-) ");

虽然有些分析者支持C++式的评论,但我使用的是JsonCpp 专案在这些例子中,有这样一个例子:

// Configuration options
{
    // Default encoding for text
    "encoding" : "UTF-8",

    // Plug-ins loaded at start-up
    "plug-ins" : [
        "python",
        "c++",
        "ruby"
        ],

    // Tab indent size
    "indent" : { "length" : 3, "use_space": true }
}

jsonlint (jsonlint)无法验证这一点。 因此, 批注是解析器特定的扩展名, 而不是标准扩展名 。

另一个解析器是杰森5.

JSON 替代 JSON 的替代方案汤加.

另一种替代办法是:jjsonc 喷气管.

最新版本的最新版本nlohmann/json(日元)可选择支持忽略对解析的评论 。
