我可以在json文件里使用注释吗? 如果是的话,怎么写?
当前回答
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。
其他回答
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):
{
"Notations": [
{
"anchorX": 333,
"anchorY": 265,
"areaMode": "Ellipse",
"extentX": 356,
"extentY": 294,
"opacity": 0.5,
"text": "Elliptical area on top",
"textX": 333,
"textY": 265,
"title": "Notation 1"
},
{
"anchorX": 87,
"anchorY": 385,
"areaMode": "Rectangle",
"extentX": 109,
"extentY": 412,
"opacity": 0.5,
"text": "Rect area\non bottom",
"textX": 98,
"textY": 385,
"title": "Notation 2"
},
{
"anchorX": 69,
"anchorY": 104,
"areaMode": "Polygon",
"extentX": 102,
"extentY": 136,
"opacity": 0.5,
"pointList": [
{
"i": 0,
"x": 83,
"y": 104
},
{
"i": 1,

},
{

"x": 83,
"y": 104
}
],
"text": "Simple polygon",
"textX": 85,
"textY": 104,
"title": "Notation 3"
}
],
"imageXW": 512,
"imageYW": 512,
"imageName": "lena_std.ato",
"tinyDocs": {
"c01": "JSON image notation data:",
"c02": "-------------------------",

"c12": "you use to scale the notation areas to their proper",
"c13": "locations and sizes for your display of the image,",
"c14": "regardless of scale.",

"c16": "For Ellipses, anchor is the center of the ellipse,",
"c17": "and the extents are the X and Y radii respectively.",
"c18": "",
"c19": "For Rectangles, the anchor is the top left and the",
"c20": "extents are the bottom right.",
"c21": "",
"c22": "For Freehand and Polygon area modes, the pointList",
"c23": "contains a series of numbered XY points. If the area",
"c24": "is closed, the last point will be the same as the",
"c25": "first, so all you have to be concerned with is drawing",
"c26": "lines between the points in the list. Anchor and extent",
"c27": "are set to the top left and bottom right of the indicated",

"c37": "Opacity is a value between 0 and 1, where .5 represents",
"c38": "a 50% opaque backdrop and 1.0 represents a fully opaque",

"c40": "only if the user hovers the pointer over the image,",
"c41": "and that the text associated with the regions be drawn",
"c42": "only if the user hovers the pointer over the indicated",
"c43": "region."
}
}
叹息。为什么不只添加字段,例如:
{
"note1" : "This demonstrates the provision of annotations within a JSON file",
"field1" : 12,
"field2" : "some text",
"note2" : "Add more annotations as necessary"
}
只要确保你的"笔记本"名字 不与任何真实的字段冲突。
如果您的文本文件, 即json 字符串, 将会被某个程序读取, 使用前要删除 c 或 c++ 样式的注释会有多困难 ?
回答:如果你这样做,它将是一个班轮。那么json文件可以用作配置文件。
虽然json不支持评论,jsonc支持。
使用 jsonc 剖析器 。 抱歉, 如果回答为时已晚, 请将您的文件命名为“. jsonc ” 扩展名, 并使用 jsonc 剖析器 。
jsonWithComments.jsonc
例如:
{
// This is a comment!
"something": "idk"
}
如果这还不清楚, 我认为机器人是奇怪的。 请在投票前先试一下, 这个问题没有帮助 。
没有。
json is only data. 如果您包含一个注释, 那么它也必须是数据 。
您可以有一个名为“_comment”(或某物)的指定数据元素,该元素应该被使用json数据的应用程序忽略。
您也许最好在生成/接收json的进程中得到评论,因为他们应该知道json数据的预发内容,或者至少知道它的结构。
但如果你决定:
{
"_comment": "comment text goes here...",
"glossary": {
"title": "example glossary",
"GlossDiv": {
"title": "S",
"GlossList": {
"GlossEntry": {
"ID": "SGML",
"SortAs": "SGML",
"GlossTerm": "Standard Generalized Markup Language",
"Acronym": "SGML",
"Abbrev": "ISO 8879:1986",
"GlossDef": {
"para": "A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso": ["GML", "XML"]
},
"GlossSee": "markup"
}
}
}
}
}
