How to use veb to write a post interface that can receive json data

[Avey777]

struct RequestOfferid {
	offer_id_i64 i64
}

@["/mall1688_json/";post]
pub fn (app &App) mall1688_json(mut ctx Context,data string) veb.Result {
	eprintln('------------ ${@METHOD} -----------------')

	//解析JSON数据到结构体
	if data == "" {
		return ctx.json({"code": "104", "msg": "json string is empty"})
	}
	
	request_data := json.decode(RequestOfferid,data) or {return ctx.json({"code": "101", "msg": "json字符串解析错误:$data"})}

	sqldata := mall_1688(request_data.offer_id_i64) or { return ctx.json({"code": "102", "msg": "数据库链接错误"}) }

	return ctx.json(sqldata)

}

curl -X POST http://localhost:8082/mall1688_json/ -H "Content-Type: application/json" -d '{"offer_id_i64": 773317320626}'

api response:

{
	"code": "104",
	"msg": "json string is empty"
}

The above code can only receive data in the form-data format. So what should I do if I want the post interface to receive data of type application/JSON ?
