How to create array of objects in golang?
问题
我有一个需求，需要将对象数组存储在一个变量中。这些对象的类型各不相同。请参考以下示例：
v := [ {"name":"ravi"},
["art","coding","music","travel"],
{"language":"golang"},
{"experience":"no"}
]
请注意，第二个元素本身是一个字符串数组。经过研究，我考虑将其存储为接口类型，如下所示：
var v interface{} = [ {"name":"ravi"},
["art","coding","music","travel"],
{"language":"golang"},
{"experience":"no"}
]
然而，我遇到了一些编译错误，我找不出原因。

I have a requirement in which I need to store array of objects in a variable. The objects are of different types. Refer to following example:
v := [ {"name":"ravi"},
["art","coding","music","travel"],
{"language":"golang"},
{"experience":"no"}
]
Notice the second element is array of string itself. After research, I thought of storing this as interface type like:
var v interface{} = [ {"name":"ravi"},
["art","coding","music","travel"],
{"language":"golang"},
{"experience":"no"}
]
Still, I am getting few compilation errors which I am not able to find out.

你要求的是可能的 - playground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。你正在与类型系统作斗争，我会质疑为什么你要这样使用Go。考虑利用类型系统 - playground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)
}
英文:
What you're asking for is possible -- playground link:
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)
}
But you probably don't want to be doing this. You're fighting the type system, I would question why you're using Go if you were doing it like this. Consider leveraging the type system -- playground link:
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)
}

完美的Python语法，但不幸的是Go使用了一些不太易读的东西。

Perfect python syntax, but go unfortunately use something less readable.
