javascript - JSON.stringify 中的注释字段被忽略

Question

我正在使用一个模块将 apache 配置文件解析为 json

https://github.com/tellnes/node-apacheconf

它工作得非常完美。当我执行JSON.stringify()时生成的 JSON 对象不包含注释。console.log(config)的输出:

comments 字段在整个结构中被完全忽略。我怎样才能防止这种情况发生。

Answer 1

我认为你不能在数组中使用这样的键。

例如，尝试更改:

 DefaultType: [ 'text/plain', comments: [ [] ] ],

至:

 DefaultType: { type: 'text/plain', comments: [ [] ] },

对象包含带有值的键:{ key1: value1, key2: value2 }

数组包含逗号分隔值:[ value1, value2 ]

对象还可以包含值数组的值:{ key1: [ value1, value2 ] }

或多维:{ key1: [ value1, [ value2, value3 ] ] }

看起来您的配置对象的结构有问题。我建议更改它以匹配我的示例。
