我的json结构如下:
{
"date": "20171123",
"stories": [
{
"images": "1.jpg",
"title": "标题1"
},
{
"images": "2.jpg",
"title": "标题2"
},
{
"images": "3.jpg",
"title": "标题3"
}
],
"top_stories": [
{
"top_images": "top1.jpg",
"top_title": "top1"
},
{
"top_images": "top2.jpg",
"top_title": "top2"
},
{
"top_images": "top3.jpg",
"top_title": "top3"
}
]
}
请问如何定义schema以及如何进行增删改查?
