Y分钟速成X

其中 X=json

JSON是一个极其简单的数据交换格式。按json.org说的,它对人类易读易写,对机器易解析易生成。

一段JSON可以是下文列出的类型的任意值,但实际一般按以下两种方式之一呈现:

纯正的JSON实际上没有注释,但是大多数解析器都接受C-风格(//, /* */)的注释。一些解析器还容许trailing comma,即最后一个数组元素或最后一个对象属性之后的逗号。不过为了兼容性最好避免。

因此,本教程的一切都会是100%有效的JSON。幸亏,它的表达能力很丰富。

支持的数据类型:

{
  "key": "value",

  "keys": "must always be enclosed in double quotes",
  "numbers": 0,
  "strings": "Hellø, wørld. All unicode is allowed, along with \"escaping\".",
  "has bools?": true,
  "nothingness": null,

  "big number": 1.2e+100,

  "objects": {
    "comment": "Most of your structure will come from objects.",

    "array": [0, 1, 2, 3, "Arrays can have anything in them.", 5],

    "another object": {
      "comment": "These things can be nested, very useful."
    }
  },

  "silliness": [
    {
      "sources of potassium": ["bananas"]
    },
    [
      [1, 0, 0, 0],
      [0, 1, 0, 0],
      [0, 0, 1, "neo"],
      [0, 0, 0, 1]
    ]
  ],

  "alternative style": {
    "comment": "check this out!"
  , "comma position": "doesn't matter, if it's before the next key, it's valid"
  , "another comment": "how nice"
  },



  "whitespace": "Does not matter.",



  "that was short": "And done. You now know everything JSON has to offer."
}
