1.1 Routing interface registration

authed.DELETE("product/:id", api.DeleteProduct)

1.2 Writing interface functions

1.2.1 service layer

• Defining a structure for deleting a commodity service

type DeleteProductService struct {
    
    
}

• Define the methods under this struct

func (service *DeleteProductService) Delete(id string) serializer.Response {
    
    
...
}

• Call the method under the service

deleteProductService := service.DeleteProductService{
    
    }

• context return

c.JSON(200, res)

func DeleteProduct(c *gin.Context) {
    
    
	deleteProductService := service.DeleteProductService{
    
    }
	res := deleteProductService.Delete(c.Param("id"))
	c.JSON(200, res)
}

1.3 Writing service functions

• Find the item that needs to be deleted by id

	var product model.Product
	err := model.DB.First(&product, id).Error

• delete item

err = model.DB.Delete(&product).Error

• return result

return serializer.Response{
    
    
		Status: code,
		Msg:    e.GetMsg(code),
	}

1.4 Authentication Service
