Question

以下是一个示例：https://play.golang.org/p/aQXJzH6Yjo

i := make(map[string]interface{})
i["some"] = []interface{}{
        []interface{}{1, 2, "3--"},
        map[string]interface{}{
                "value": "some",
        },
 }

如何将附加值推入[]interface{}{1, 2, "3--"}切片？我基本上需要创建任意数据结构，将其转换为json。查看https://github.com/Jeffail/gabs，但它似乎不允许创建嵌套数组

这有点乱，但你可以按照这里所示的那样做（我遗漏了错误处理）：https://play.golang.org/p/JgZ4fAgRAz

i := make(map[string]interface{})
i["some"] = []interface{}{
    []interface{}{1, 2, "3--"},
    map[string]interface{}{
        "value": "some",
    },
}
fmt.Println(i)
var myval []interface{} = i["some"].([]interface{})
var mylist []interface{} = myval[0].([]interface{})

mylist = append (mylist, "Another value")

// Replace the potentially new slice into element 0
myval[0] = mylist

// No need to write back to the map - the slice is a reference type
fmt.Println(i)

如何将值推送到嵌套的map [string] interface {}切片？
