*.json文件通常用作配置文件或静态数据,因此需要评论 * 一些像Netbeans这样的编辑在 *.json中接受评论。

问题在于将内容解析到对象上。 解决办法是总是应用清洁功能( 服务器或客户端 ) 。

php /p

 $rgx_arr = ["/\/\/[^\n]*/sim", "/\/\*.*?\*\//sim", "/[\n\r\t]/sim"];
 $valid_json_str = \preg_replace($rgx_arr, '', file_get_contents(path . 'a_file.json'));

手笔

valid_json_str = json_str.replace(/\/\/[^\n]*/gim,'').replace(/\/\*.*?\*\//gim,'')

json背后的想法是提供各种应用程序之间的简单数据交换。 这些应用程序通常是基于网络的,语言是javascript。

但是,虽然数据显然需要由解析代码忽略或具体处理, 但是,它实际上不允许这样的评论, 但是,作为数据中的名称/价值对之一,通过一个评论肯定行得通,

简逊档案不应该包含传统意义上的评论。 它应该只是数据。

详情请查看json网站。

正如许多答案已经指出的,Json在本地没有评论。当然,有时你还是想要评论。对python来说,两种方法就是评论json(和//仅对python 2)或json_tricks(或//对python 2和python 3),这有其他几个特点。免责声明:我做了json_tricks。

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):

如果您正在使用带有 asp. net 的牛顿软性.json 库来读取/删除您可以在 json 内容中使用批注 :

//"名字": "字符串"//"id":

或

* 这是评论示例 */

ps:单行评论仅用6+版本的牛tonoftjson支持。

给无法从框中思考的人附加注释 : 我使用 json 格式用于 Asp. net 应用程序的基本设置 。 i 读取文件, 将其转换成设置对象 , 并使用 tonoft 库 , 必要时使用 。

我更喜欢在json档案中写关于每个设置的评论, 我真的不在乎json格式的完整性, 只要我使用的图书馆可以使用。

i 认为这比创建单独的“ 设置 ” 设置更容易使用/ 理解 。 读取我的文件, 并解释文件中的设置 。

如果你对这种用法有问题, 对不起, 精灵已经出灯了。 人们会发现 Json 格式的其他用法, 您对此无能为力 。

是的,你可以,但你的分析可能会失败(没有标准)。

要进行剖析,您应该删除这些注释,或者通过手写,或者使用正则表达式:

它替换任何评论,例如:

/****
 * Hey
 */

/\/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*\/+/

它替换任何评论,例如:

// Hey

/\/\/.*/

你可以做这样的事情:

jsonString = jsonString.replace(/\/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*\/+/, "").replace(/\/\/.*/,"")
var object = JSON.parse(jsonString);
