json - 嵌套映射返回 json array[]

Question

如何创建嵌套的 JSON 数组？还有其他简单的方法吗？

我试过这个:

var m1 = make(map[string]interface{})
m1 = append(tickets, ptotal)                      //error is here
i.Data["json"] = m1
i.ServeJSON()

但它显示此错误:

cannot use append(tickets, ptotal) (type []interface {}) as type map[string]interface {} in assignment

我可以这样做，但它根本没有嵌套:

// some := append(tickets, map[string]int64{"totalpage": ptotal})

我想要这个 JSON:

[
  {tickets
     name:value,
  },
],
[
  {
   totalpage: 10
  }
]

我想要Playground of mine

Answer 1

var tickets []interface{}
var ptotal int64
tickets, ptotal, err := models.GetAllTicket(query, fields, sortby, order, offset, limit)
if err != nil {
    // bulabula
}
i.Data["json"] = append(tickets, map[string]int64{"totalpage": ptotal})
