Method and system for realizing hot upgrade of website version

Abstract

The invention discloses a method and a system for realizing the hot upgrade of a website version. The method comprises the following steps: S1: when a website is loaded for the first time, a front end or a rear end creates a client side cache, the front end and the rear end make an agreement on all functions of the website to obtain a function state table of a uniform format, a server sends the function state table to the front end, and the function state table is stored in the client side cache to serve as a local state table; S2: the client side initiates heartbeat to the server at certain time intervals, and requests to obtain the server state table of the server; S3: the client side compares the server state table with the local state table to judge whether the local state table is consistent with the server state table or not, S2 is started again if the local state table is consistent with the server state table, and otherwise, a performance function corresponding to the server state table is executed to update the corresponding function of the website; and S4: whether the function of the website succeeds in being updated or not is judged, if the function of the website succeeds in being updated, the local state table is updated to be consistent with the server state table and is stored in the client cache, and otherwise, S2 is started again.

Description

technical field [0001] The invention relates to the field of live website version update, in particular to a method and system for realizing hot upgrade of website version.
