嵌套Json Marshall或编码

Question

For a project of mine, i need to encode into Json like below. I have all the values as variables. Any help is appreciated.

{"id":[{"name":"Test","Class":[{"Grade":"2","id":"34"}]}],"age":"5"}

this is the code i have tried

type classx  struct {
    Grade string `json:"grade"`
    Id string `json:"id"`        
}
type idx  struct {
    Name string `json:"name"`
    Class []classx


}
type Response struct {
    Age  string     `json:"age"`
    Id []idx 
} 

But getting an error "cannot use classx literal (type classx) as type []classx in field value"

Answer 1

The Class field is a slice. You have given it a struct

Wrong:

Response{Id:[]idx{idx{Class:classx{}}}}

Correct:

Response{Id:[]idx{idx{Class:[]classx{}}}}
