What if an HTTP request contains data of different types?

[Avey777]

For example, how can I implement the following data structure? Is there any other solution to complete the work of HTTP requests?

{
  "auto_fill_spu_property": true,
  "carousel_video_url": "https://example.com/00.png",
  "cat_id": 13465456,
  "goods_properties": ["goods_properties": 3213, "img_url": "https://example.com/00021.png"]
}

mut req := http.Request{
    method: http.Method.post
    url: req_url
    data: {
    "auto_fill_spu_property": true,
    "carousel_video_url": "https://example.com/00.png",
    "cat_id": 13465456,
    "goods_properties": ["goods_properties": 3213, "img_url": "https://example.com/00021.png"]
    }
}
req.add_custom_header('Content-Type', 'application/json')!
req.add_custom_header('Authorization', authorization)!

For JSON data containing different data types, the 'json2. raw decode' in the v language can achieve correct decoding. But we also need different data structures when requesting many APIs. Of course, I know that v's JSON only supports one data type. What should I do in this situation? What do I need to do to make the correct request to the HTTP mentioned above

[JalonSolov]

You can try using https://github.com/Ddiidev/Json2V to create V structs, then decode to those structs.

You misunderstood me. I don't want to decode json data; I want to know how to write such json data using V.

[JalonSolov]

Turn that into a struct, then call json2.encode()

I have solved the above problem? And now I have a new json encoding problem

As shown in the figure, writing like this will perform json encoding twice, resulting in the data obtained by the get request not being in normal json format. What should I do in this case?

Since Root_shopee{} is not a data type supported by the v language, I cannot use it as a function return type. I only thought of decoding it into json and then processing the data format of [ ]string as the function return format.

Do you have a better way for me to avoid repeated json encoding?

[JalonSolov]

Simple: Don't encode it yourself. ctx.json(sqldata[0]) will encode it for you, because calling the .json() method tell it to encode to JSON.

[Avey777]

pub fn mall_shopee_additem(offid i64) ![]string {
       /*.......*/
	mut string_list := []string{}
	for row in res {

		shopee := &Root_shopee{
			category_id: int(row.category_id)
			description:'${row.description}'
			image: Image{
			  image_id_list: ["${row.images}"]
			}
			item_name: '${row.subject}'
			logistic_info: [LogisticInfo{
			  enabled: true
				logistic_id:136546464
			}]
			original_price: row.consign_price.f32()
			pre_order: PreOrder{
			  is_pre_order: true
			}
			weight: row.weight.f32()
		}
		data := json.encode(shopee)
		string_list << data
	}
	return string_list
}

If I don't do json encoding here, I don't know how to return the data of the &Root_shopee{ } structure

[JalonSolov]

Try something like...

pub fn mall_shopee_additem(offid i64) ![]string {
       /*.......*/
	mut item_list := []Root_shopee{}
	for row in res {
		item_list << Root_shopee{
			category_id: int(row.category_id)
			description:'${row.description}'
			image: Image{
			  image_id_list: ["${row.images}"]
			}
			item_name: '${row.subject}'
			logistic_info: [LogisticInfo{
			  enabled: true
				logistic_id:136546464
			}]
			original_price: row.consign_price.f32()
			pre_order: PreOrder{
			  is_pre_order: true
			}
			weight: row.weight.f32()
		}
	}
	return item_list
}

[Avey777]

pub fn mall_shopee_additem(offid i64) ![]Root_shopee{
       /*.......*/
	mut item_list := []Root_shopee{}
	for row in res {
		item_list << Root_shopee{
			category_id: int(row.category_id)
			description:'${row.description}'
			image: Image{
			  image_id_list: ["${row.images}"]
			}
			item_name: '${row.subject}'
			logistic_info: [LogisticInfo{
			  enabled: true
				logistic_id:136546464
			}]
			original_price: row.consign_price.f32()
			pre_order: PreOrder{
			  is_pre_order: true
			}
			weight: row.weight.f32()
		}
	}
	return item_list
}

This is great!
Thank you very much for your answer. I will continue to learn and improve struct.

I changed the return parameter type of the example you gave to: ![]Root_shopee

[JalonSolov]

Err... yes, that needed to be done, too. :-)
