如何在golang中创建对象数组?
我有一个需要将对象数组存储在变量中的要求。对象是不同类型的。请参考以下示例:
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,我想将其存储为以下接口类型:
var v interface{} = [ {"name":"ravi"}, ["art","coding","music","travel"],
{"language":"golang"},
{"experience":"no"}
]
尽管如此,我还是遇到了一些无法找到的编译错误。

您要的是可能的- 游乐场链接:
package mainimport "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)
}
但是您可能不想这样做。您正在与类型系统进行斗争,如果您这样做,我会质疑您为什么要使用Go。考虑利用类型系统-

package mainimport "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)
}
