Information synchronization method and device, electronic equipment and storage medium

The invention relates to an information synchronization method and a device, electronic equipment and a storage medium. The information synchronization method comprises the following steps: receivingan information change message sent by a server; sending an information synchronization request to the server in response to the situation that the predetermined data change exists in the information change message; receiving data information issued by the server according to the information synchronization request; and updating a local database according to the information change message and the data information. Through the process, when the information of the server side is changed; the information change message sent by the server is directly and timely obtained; synchronization of equipment end information is realized; the possibility of polling whether information change is performed on the server regularly is reduced, the pressure of the server is reduced, the number of equipment ends capable of serving the
