)

type Request struct {
    Samples []Info `json:"Infos" validate:"required,min=1"`
}

type Info struct {
    ID      *string
    Content *string `validate:"omitempty,min=1,max=10"`
}

func main() {

    str := `{"Infos":[{"Content":"1111111111111111111xxxxxxxx11","ID":"xx11"}]}`
    info := Request{}

    json.Unmarshal([]byte(str), &info)

    validate := validator.New()
    err := validate.Struct(info)

    fmt.Println(err)

}

output:

<nil>

max=10 not work
