A method for invoking hardware of cross-browser financial self-service terminal based on websocket

Abstract

The invention discloses a WebSocket-based cross-browser financial self-service terminal hardware calling method, including a WebSocket client, a WebSocket server, and a hardware driver; the WebSocket client uses Javascript and WebSocket technology to encapsulate hardware instructions, and connects and sends hardware instructions. The instruction sends a message to the WebSocket server; the WebSocket server is used to start the WebSocket service, and implements the encapsulation of the call to the hardware driver according to the hardware instruction, and returns the hardware execution result and the hardware event message to the WebSocket client; the present invention Based on the WebSocket technology that has been fully implemented by mainstream browsers, the Javascript code is used to implement the call to the hardware of financial self-service equipment, without the need to extend the browser itself, and it is compatible with various mainstream browsers that support WebSocket and Javascript And custom browsers, independent of a specific browser, can run in all current major browsers.

Description

technical field [0001] The invention relates to a WebSocket-based cross-browser financial self-service terminal hardware calling method, and belongs to the technical field of financial self-service terminals. Background technique [0002] With the application of financial self-service equipment in more and more industries, the limitations of hardware invocation methods in the application development process are also clearly exposed. Many industrial applications are developed in the web method, which was originally limited to the financial self-service terminal hardware invocation in the banking industry. It is difficult to successfully access the application in these industries, which has obvious restrictions on the deployment of financial self-service equipment in other industries. [0003] WebSocket technology is a communication protocol set as a standard by the international organization IETF. W3C has also positioned its interface as an international standard. This techno...
