JSON简单常用总结

JSON

因为 JSON 是一个极其简单的数据交换格式,本教程最有可能成为有史以来最简单的 Learn X in Y Minutes。

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。为了兼容性,最好不要在其中写这样形式的注释。

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:

  • 字符串: "hello", ""A quote."", "\u0abe", "Newline.\n"
  • 数字: 23, 0.11, 12e10, 3.141e-10, 1.23e+4
  • 对象: { "key": "value" }
  • 数组: ["Values"]
  • 其他: true, false, null
{
  "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]
    ]
  ],

  "that was short": "And, you're done. You now know everything JSON has to offer."
