go - Golang parse a json with DYNAMIC key -

i have json string follows:

j := `{"bvu62fu6dq": {            "name": "john",            "age": 23,            "xyz": "weu33s"            .....            .....}       }`

i want extract value of name , age above json string. looked @ example given @ golang site http://play.golang.org/p/yqgzp7kpp9

but problem key in json on top level dynamic. means bvu62fu6dq dynamic. have created struct this:

 type info struct {    uniqueid map[string]string  }

but not sure how extract name , age. code @ http://play.golang.org/p/vbdkd3xikc

i believe want this:

type person struct {     name string `json:"name"`     age  int    `json:"age"` }  type info map[string]person

then, after decoding works:

fmt.printf("%s: %d\n", info["bvu62fu6dq"].name, info["bvu62fu6dq"].age)
