Pattern: Handler
Responsibility
HTTP only: bind JSON/query → validate → call service interface → map errors to envelope.
Shape
type ReportService interface {
Decode(ctx context.Context, in DecodeInput) (*DecodeOutput, error)
}
type ReportHandler struct {
svc ReportService
}
func (h *ReportHandler) Decode(c *gin.Context) {
var req DecodeRequest

response.Fail(c, 400, 10000, "invalid request")
return
}
out, err := h.svc.Decode(c.Request.Context(), toInput(req))
if err != nil {
// map domain errors → codes
response.Fail(c, 400, 30001, err.Error())

response.OK(c, out)
