Abstract
A method includes: receiving a resource acquisition request of a target resource, and calculating resource identification information included in the resource acquisition request by using a first preset algorithm to obtain a target feature index value; if a resource file corresponding to the target feature index value exists locally, feeding back the resource file corresponding to the target feature index value, and if not, transmitting a data acquisition request of a specified segment of the target resource to a resource server of the target resource; receiving data of the specified segment fed back by the resource server, and calculating the data of the specified segment by using a second preset algorithm to obtain a target content index value; and if a resource file corresponding to the target content index value exists locally, feeding back the resource file corresponding to the target content index value, and if not, transmitting the resource acquisition request to the resource server.
