Client program updating method, device and system

Abstract

The invention provides a method, a device and a system for updating a client program, relates to the technical field of client applications, and can access a server corresponding to a current client when monitoring starting information of the client program. Obtaining first version information of a client program pre-stored by the server; Comparing whether the first version information is consistent with second version information of the current client program or not; Downloading an update file corresponding to the first version information from the server side when the comparison is inconsistent; Therefore, the current client program is updated. comparing the first version information with the second version information of the current client program to determine whether to update the client program; The consistency of the second version information of the current client program and the first version information of the server is effectively judged, so that effective updating of the client program is realized, the updating efficiency of the client program is improved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of client applications, in particular to a method, device and system for updating client programs. Background technique [0002] CS (Client / Server, client / server) architecture software products generally have clients, and there are problems such as complex program design, high development cost, long cycle, poor software portability, and difficult upgrade and maintenance. Therefore, the general server only stores data , most of the business logic is implemented on the client. If the product business logic is adjusted or the interface style is adjusted, the client software needs to be redeveloped, and all need to be packaged and released. All users need to download a new client or upgrade the client software. The new system can be used. [0003] Therefore, a three-tier CS structure system came into being, which separates the presentation layer, application layer, and service layer. In this way, the re...

[0002] CS (Client / Server, client / server) architecture software products generally have clients, and there are problems such as complex program design, high development cost, long cycle, poor software portability, and difficult upgrade and maintenance. Therefore, the general server only stores data , most of the business logic is implemented on the client. If the product business logic is adjusted or the interface style is adjusted, the client software needs to be redeveloped, and all need to be packaged and released. All users need to download a new client or upgrade the client software. new system available

[0003] Therefore, a three-tier CS structure system came into being, which separates the presentation layer, application layer, and service layer. In this way, the relative independence of the three layers can be maintained logically. Each layer can be developed independently and in parallel, but the presentation layer still uses Native development. method, still has the trouble of modifying an interface style and repackaging and releasing the version. If you use the BS (Browser / Server, browser / server) architecture, that is, the presentation layer is implemented in the browser, and there are many high-performance rendering and computing functions. Difficult to implement in browsers, because many lower-level graphics rendering operations are limited at the browser kernel level

Therefore, when any layer of the presentation layer, application layer, or service layer is updated, the user needs to re-download the new client or upgrade the client program to use the new system, which reduces the update efficiency of the client program and the user experience.
