Information synchronization method and device

The invention discloses an information synchronization method and an information synchronization device. The method comprises the following steps that a server receives an information publish request sent by a user equipment and inquires corresponding synchronization configuration information according to a user identification and a target platform identification carried in the information publish request; the server shows the information requested to be published in a target platform and synchronously shows the information in a synchronization platform appointed in the synchronization configuration information according to the inquired synchronization configuration information; and when the server receives a comment request of the information showed in the synchronization platform synchronously sent by the user equipment and determines to feed the comment back to the target platform, the server shows the comment in the synchronization platform and the target platform. According to the information synchronization method and the device, the information synchronization showing efficiency is improved and the condition that the different platforms are converged to a unified integration page by aiming at the comment of the same content is realized.
