[英]How to create array of objects in golang?
I have a requirement in which I need to store array of objects in a variable. 我有一个要求,我需要在变量中存储对象数组。 The objects are of different types. 对象是不同类型的。 Refer to following example: 请参阅以下示例:
v := [ {"name":"ravi"},
["art","coding","music","travel"],
{"language":"golang"},
{"experience":"no"}
]
Notice the second element is array of string itself. 注意第二个元素是字符串本身的数组。 After research, I thought of storing this as interface type like: 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"}
]
Still, I am getting few compilation errors which I am not able to find out. 不过,我收到的编译错误很少,我无法找到。
What you're asking for is possible -- playground link : 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)
}
But you probably don't want to be doing this. 但你可能不想这样做。 You're fighting the type system, I would question why you're using Go if you were doing it like this. 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。 Consider leveraging the type system -- playground link : 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)
}
Perfect python syntax, but go unfortunately use something less readable. 完美的python语法,但遗憾的是使用不太可读的东西。 https://golang.org/ref/spec#Composite_literals https://golang.org/ref/spec#Composite_literals
