    • Disclosed are a resource sharing method and device, and a storage medium. The technical solution in the embodiments of the present invention is applied to use a relationship chain to perform authentication control. When a resource download link is generated, corresponding relationship chain information is added into the link, and the resource download link is recorded and sent by a sharing server. When a user needs to perform downloading according to the received resource download link, authentication is performed on the user according to the relationship chain information. Only users who have the friendly relationship corresponding to the relationship chain are permitted to download specific contents, thereby introducing a controlled resource sharing mechanism in the existing download platform system, controlling contents to be legally and orderly spread, and at the same time enabling the resource spreading process to be traced.
