Send the following characters according to the format to send 2 products
Product 1: Apple, sold by weight, number = 1, itemcode = 10001, EAN/UPC barcode = none, unit price = 15.00, print shelf life, shelf life = 10
Commodity 2: Mineral water, sold by count, number = 2, itemcode = 10002, EAN/UPC = 1234567890123, unit price = 5.00, without expiration date

By comparing the two, you can know where each field is located. Other fields are recommended to keep the default. Fields are separated from each other by TAB.
Among them floating point numbers use a special representation 1500,2 = 15.00. That is, the part before the comma is a valid digit, and the position after the comma is the decimal point.
In the unit field, 1 = by-weight, 2 = by-count
