RESOURCE ACQUISITION METHOD AND RELATED DEVICE

Embodiments of the present invention disclose a resource obtaining method and a related device, to effectively reduce redundant data transmission between a registrar and a resource server. The method in the embodiments of the present invention includes: receiving, by a registrar, a first request sent by a terminal for obtaining a target attribute included in a resource, where the first request carries a uniform resource identifier URI of the target attribute; determining, by the registrar based on the URI, that the registrar stores the resource to which the target attribute belongs, where the target attribute is partial content included in the resource; and sending, by the registrar to the terminal, a valid target attribute indicated by the URI. The embodiments of the present invention further provide a registrar and a resource server, effectively reducing redundant data transmission between the registrar and the resource server, and saving a network resource.
