如何表示字符串的JSON数组?

This is all you need for valid JSON, right?

这就是有效JSON所需要的，对吧?

["somestring1", "somestring2"]

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

我将详细介绍克里斯托尔的精彩回答，并从他的精彩参考中带来图片。

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

一个有效的JSON总是以花括号{或方括号[，没有别的了。

{ will start an object:

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

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

提示:虽然javascript接受单引号，但JSON只接受双引号。

[ will start an array:

[value, value]

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

提示:任何JSON解析器都会忽略元素之间的空格。

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.

是的，[a"， "b"]是一个完全有效的JSON，就像你可以尝试链接Manish point一样。

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

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"]
}

Your JSON object in this case is a list. JSON is almost always an object with attributes; a set of one or more key:value pairs, so you most likely see a dictionary:

这里的JSON对象是一个列表。JSON几乎总是具有属性的对象;一组或多个键:值对，所以您很可能会看到字典:

{ "MyStringArray" : ["somestring1", "somestring2"] }

then you can ask for the value of "MyStringArray" and you would get back a list of two strings, "somestring1" and "somestring2".

然后您可以询问“MyStringArray”的值，您将得到两个字符串的列表，“somestring1”和“somestring2”。

I use http://jsonlint.com/ to validate my JSON.

我使用http://jsonlint.com/验证我的JSON。

Basically yes, JSON is just a javascript literal representation of your value so what you said is correct.

基本上，JSON只是你的值的javascript文字表示，所以你说的是对的。

You can find a pretty clear and good explanation of JSON notation on http://json.org/

您可以在http://json.org/上找到一个非常清楚、很好的JSON符号解释。

String strJson="{\"Employee\":
[{\"id\":\"101\",\"name\":\"Pushkar\",\"salary\":\"5000\"},
{\"id\":\"102\",\"name\":\"Rahul\",\"salary\":\"4000\"},
{\"id\":\"103\",\"name\":\"tanveer\",\"salary\":\"56678\"}]}";

This is an example of a JSON string with Employee as object, then multiple strings and values in an array as a reference to @cregox...

这是一个JSON字符串的例子，Employee作为对象，然后是数组中的多个字符串和值作为对@cregox的引用……

A bit complicated but can explain a lot in a single JSON string.

有点复杂，但可以在一个JSON字符串中解释很多。
