json定义
JSON is built on two structures:
- A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
- An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.
JSON结构的两种定义:对象、数组
根据JSON的字面含义
JSON (JavaScript Object Notation) is a lightweight data-interchange format.
一直认为object才叫做json,是key,value 键值对的对象形式才算,昨天和同事沟通数据接口发现这块存在歧义,事实证明我的理解是存在误区的;
arry 也同样可以序列化为json,展示形式不一样,如上官方描述,两种数据结构,key/val 键值对和有序序列;
