Embodiment Construction

[0044] The code system is the encoding mode of the barcode, and each code system has its own encoding rules and character sets. There are more than 100 types of one-dimensional barcodes, commonly used are UPC (Uniform Production Code, unified product code), EAN (European Article Number, European Article Number), 39 codes, cross 25 codes, 128 codes, 93 codes, and library codes. Deba (Codabar) yards and so on. Two-dimensional barcode codes include Data Matrix (Data Matrix), QR (Quick Response, Quick Response) code, MaxiCode code, Vericode code, PDF417 (Portable Data File 417, portable data file 417) and so on.

[0045] When generating a barcode, the original information is usually encoded according to the adopted code system to obtain barcode data (usually a character string); then the barcode image is drawn using the barcode data.

[0046] When different code systems are used, the densities of barcode images of the same length (for one-dimensional barcodes) or the same area (f...

Abstract

This specification provides a method for generating barcodes, which is applied to the server. The method includes: receiving a barcode generation request sent by the terminal; generating barcode information using at least two code systems according to the barcode generation request; returning a barcode generation response to the terminal , including the generated at least two barcode information, for the terminal to rotate the barcode image corresponding to each barcode information.

Description

technical field [0001] This specification relates to the technical field of network communication, and in particular to a method and device for generating barcodes. Background technique [0002] A barcode is a group of bar and space symbols arranged according to certain coding rules to represent information composed of certain characters, numbers and symbols. Barcodes include one-dimensional barcodes and two-dimensional barcodes. Among them, one-dimensional barcodes express information by arranging multiple black bars and blanks of different widths according to certain rules; two-dimensional barcodes (also called two-dimensional codes) use a specific Geometric figures are black and white figures distributed on a plane (two-dimensional direction) according to certain rules to record information. [0003] With the development of mobile Internet technology and the popularization of smart terminals, the application of barcodes is becoming more and more extensive, and people are...
