您如何表示一个JSON字符串数组? [英] How do you represent a JSON array of strings?

问题描述

这就是有效JSON所需的全部，对吧?

["somestring1", "somestring2"]

解决方案

我将在 ChrisR 很棒的答案，并从他的很棒的推荐书中提取图像.

有效的JSON总是以花括号{或方括号[开头.

{将启动object:

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

提示:尽管javascript接受单引号'，但JSON只接受双引号".

[将启动array:

> /p>

[value, value]

提示:任何JSON解析器始终会忽略元素之间的空格.

value是object，array，string，number，bool或null:

是的，["a", "b"]是一个完全有效的JSON，就像您可以尝试Manish指向的链接. /p>

这里有一些额外的有效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"]
}

This is all you need for valid JSON, right?

["somestring1", "somestring2"]

解决方案

I'll elaborate a bit more on ChrisR awesome answer and bring images from his awesome reference.

A valid JSON always starts with either curly braces { or square brackets [, nothing else.

{ will start an object:

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

Hint: although javascript accepts single quotes ', JSON only takes double ones ".

[ will start an array:

[value, value]

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

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

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

Here are a few extra valid JSON examples, one per block:

{}

[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"]
}
