概念介绍
还是先简单说说Json的一些例子吧。注意,以下概念是我自己定义的,可以参考.net里面的TYPE的模型设计
如果有争议,欢迎提出来探讨!
1.最简单:
{"total":0}
total就是值,值是数值,等于0
2. 复杂点
{"total":0,"data":{"377149574" : 1}}
total是值,data是对象,这个对象包含了"377149574"这个值,等于1
3. 最复杂
{"total":0,"data":{"377149574":[{"cid":"377149574"}]}}
total是值,data是对象,377149574是数组,这个数组包含了一些列的对象,例如{"cid":"377149574"}这个对象。
有了以上的概念,就可以设计出通用的json模型了。
