think that there are two struct, they have different fields, hope that
there has a function merge(a,b interface{}) interface{}, input param are
any two struct, they may have same-type, or have different-type. output
param is a struct that composed the two input struct, example type A
sturct{Name string}, type B struct{Age int}, a,b :=A{"xxx"},B{10} called
c:= merge(a,b), c is interface{}, and
import "github.com/google/go-querystring/query",
v, _ := query.Values(opt)
fmt.Print(v.Encode()) // will output: "name=xxx&age=10"
