这取决于你的JSON图书馆Json.NET支持 JavaScript 风格的评论,/* commment */.

见见另一个堆叠溢出问题.

原为:JSON发明家说:

JSON没有评论。 JSON 编码器必须输入输出评论。 JSON 编码器可能接受和忽略评论。

功用jjq jq包含一个解码器, 它允许“ #” 式的评论, 所以jq 是一种工具, 可以与 JSON 与注释文件一起使用, 只要这些文件被当作“ jq 程序” 处理, 而不是作为 JSON 文件处理 。 例如 :

$ jq -ncf <(echo $'[1, # one\n2 ] # two') 
[1,2]

更重要的是,jq可以处理庞大的JSON与评论文件作为程序;这可以用众所周知的JSON文件加以说明:

$ ls -l JEOPARDY_QUESTIONS1.json
-rw-r--r--  2 xyzzy  staff  55554625 May 12  2016 JEOPARDY_QUESTIONS1.json

$ jq -nf JEOPARDY_QUESTIONS1.json | jq length
216930

如果您的文本文件, 即 JSON 字符串, 将会被某个程序读取, 使用 C 或 C++ 样式之前要删除 C 或 C+ 样式的注释会有多困难 ?

答复:这将是一个班轮。 如果您这样做, JSON 文件可以用作配置文件 。

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 。

我在目前项目中遇到这个问题,因为我有相当一部分JSON, 需要一些评论才能让事情容易记住。

我用这个简单的 Python 函数替换备注( U)json.loads转换成dict:

import json, re

def parse_json(data_string):
  result = []
  for line in data_string.split("\n"):
    line = line.strip()
    if len(line) < 1 or line[0:2] == "//":
      continue
    if line[-1] not in "\,\"\'":
      line = re.sub("\/\/.*?$", "", line)
    result.append(line)
  return json.loads("\n".join(result))

print(parse_json("""
{
  // This is a comment
  "name": "value" // so is this
  // "name": "value"
  // the above line gets removed
}
"""))

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。

例如,这里,这里,这里,这里,我的图像处理系统已保存图像标记和一些基本格式化(注释)信息( 在底部) :
