你如何表示一个 JSON 字符串数组

发布于12月11日

This is all you need for valid JSON, right?

["somestring1", "somestring2"]

`{` will start an `object`:

left brace followed by a key string (a name that can't be repeated, in quotes), colon and a value (valid types shown below), followed by an optional comma to add more pairs of string and value at will and finished with a right brace

{ "key": value, "another key": value }

Hint:虽然javascript接受单引号'，但JSON只接受双引号".

`[` will start an `array`:

left bracket followed by value, optional comma to add more value at will and finished with a right bracket

[value, value]

Hint: spaces among elements are always ignored by any JSON parser.

And `value` is an `object`, `array`, `string`, `number`, `bool` or `null`:

Image showing the 6 types a JSON value can be: string, number, JSON object, Array/list, boolean, and null

So yeah, ["a", "b"] is a perfectly valid JSON, like you could try on the link Manish pointed.

下面是几个额外的有效JSON示例，每个块一个:

{}

[0]

{"__comment": "json doesn't accept comments and you should not be commenting even in this way", "avoid!": "also, never add more than one key per line, like this"}

[{   "why":null} ]

{
  "not true": [0, false],
  "true": true,
  "not null": [0, 1, false, true, {
    "obj": null
  }, "a string"]
}
