//post
curl --location --request POST 'http://192.168.10.211:8888/v1/product/update' --header 'Content-Type: application/json' --header 'Accept: /' --header 'Host: 192.168.10.211:8888' --header 'Connection: keep-alive' --data-raw '{
"id": 5,
"product_name": "xxxx",
"product_status": "开发中",
}'
{"id":0,"ProductName":"","ProductStatus":""}

//controller
func (c *ControllerV1) UpdateSysProduct(ctx context.Context, req *v1.UpdateSysProductReq) (res *v1.UpdateSysProductRes, err error) {
r := g.RequestFromCtx(ctx)
fmt.Println(req)
r.Response.WriteJson(req)
data := model.UpdateSysProductInput{}
err = gconv.Scan(req, &data)
if err != nil {
return nil, err
}
// 调用服务层方法更新部门信息
err = service.SysProduct().UpdateSysProduct(ctx, model.UpdateSysProductInput{
//Id: req.Id,
//ProductName: req.ProductName,
//ProductStatus: req.ProductStatus,
})

if err != nil {
	return &v1.UpdateSysProductRes{
		Message: gcode.CodeInvalidParameter.Message(),
		Code:    gcode.CodeInvalidParameter.Code(),
	}, err
}
// 更新成功，返回成功的响应
return &v1.UpdateSysProductRes{
	Message: "Product updated successfully",
}, err

}

//api struct
type UpdateSysProductReq struct {
g.Meta path:"/product/update" method:"post" tags:"product管理" summary:"更新单个product信息"
Id int v:"min:1#请选择需要update的内容" json:"id" dc:"productID" // productID
ProductCommonData
}

type UpdateSysProductRes struct {
