问题描述

我是json的新手.我见过的一些json示例在花括号内包含数据，而某些json示例在方括号内具有子数据.

I am new to json. Some json examples i have seen have data within the curly braces and some json examples have subdata within square brackets.

{
"glossary": {
    "title": "example glossary",
    "GlossDiv": {
        "title": "S",
        "GlossList": {
            "GlossEntry": {
                "ID": "SGML",
                "SortAs": "SGML",
                "GlossTerm": "Standard Generalized Markup Language",
                "Acronym": "SGML",
                "Abbrev": "ISO 8879:1986",
                "GlossDef": {
                    "para": "A meta-markup language, used to create markup languages such as DocBook.",
                    "GlossSeeAlso": ["GML", "XML"]
                },
                "GlossSee": "markup"

    }
}
}

推荐答案

方括号产生列表/数组.

The square brackets produce a list/array.

大括号会产生一个具有键/值对的对象.

The curly brackets produce an object with key/value pairs.

然后列表可以是键/值对的值.

The list can then be a value of a key/value pair.
