如何在golang中创建对象数组？

Question

我有一个要求,我需要在变量中存储对象数组.对象是不同类型的.请参阅以下示例:

 v := [ {"name":"ravi"},
        ["art","coding","music","travel"],
        {"language":"golang"},
        {"experience":"no"}
      ]

注意第二个元素是字符串本身的数组.经过研究,我想把它存储为接口类型,如:

 var v interface{} = [ {"name":"ravi"},
                       ["art","coding","music","travel"],
                       {"language":"golang"},
                       {"experience":"no"}
                     ]

不过,我收到的编译错误很少,我无法找到.

您要求的是可能的 - 游乐场链接:

package main

import "fmt"

func main() {
    v := []interface{}{
        map[string]string{"name": "ravi"},
        []string{"art", "coding", "music", "travel"},
        map[string]string{"language": "golang"},
        map[string]string{"experience": "no"},
    }
    fmt.Println(v)
}

但你可能不想这样做.你正在打击类型系统,我会问你为什么要使用Go,如果你这样做的话.考虑利用类型系统 - 游乐场链接:

package main

import "fmt"

type candidate struct {
    name string
    interests []string
    language string
    experience bool
}

func main() {
    candidates := []candidate{
        {
            name: "ravi",
            interests: []string{"art", "coding", "music", "travel"},
            language: "golang",
            experience: false,
        },
    }
    fmt.Println(candidates)
}
