JSON建构于两种结构: “名称/值”对的集合(A collection of name/value pairs)。不同的语言中,它被理解为对象(object),纪录(record),结构(struct),字典(dictionary),哈希表(hash table),有键列表(keyed list),或者关联数组 (associative array)。 值的有序列表(An o
首先,JsonObject是实现 IDictionary 接口,并在内部维护一个 SortedDictionary字典,所以他具备字典类的一切操作,比如索引等等,JsonArray 就更简单,也是一样的实现 IList接口,然后同样的在内部维护一个 List链表,以实现数组功能,对象的序列化都是通过 JsonValue 进行操作,序列化的方式也是非常的简单,就是对对像进行迭代,...

方法一:json提取器,此提取器用于提取请求返回结果中的某个值或者某一组值,用法比正则表达式要简单,标准写法为$.key,其中key为返回结果map中的一个键,如果是多层则继续用.key.key (或 ..key)进行即可,如果遇到key的value值为一个List,则使用.key[n],其中n为list中元素的编号 ...
Any sequence container (std::array, std::vector, std::deque, std::forward_list, std::list) whose values can be used to construct JSON values (e.g., integers, floating point numbers, Booleans, string types, or again STL containers described in this section) can be used to create a JS...
Using avro-spec you can convert json-values specs to avro schemas as well: import org.apache.avro.Schema; Schema avroSchema = SpecToAvroSchema.convert(spec); Modeling inheritance The json-values library simplifies the implementation of inheritance and the generation of structured data in Java. Let...

A JSON array contains a list of values separated by commas and enclosed within [ and ] characters: ["abc", 10, null, true, false] A JSON object contains a set of key-value pairs separated by commas and enclosed within { and } characters: {"k1": "value", "k2": 10} As the ...
