A resource processing method, applied to a system comprising an interface device, a background server and an authentication server; in the system, the interface device being configured with at least a first interface and a second interface, the first interface corresponding to a first cloud service, and the second interface corresponding to a second cloud service; and the method comprising: obtaining, by the background server, a resource processing indication from the first interface; performing (202, 402), by the background server, identification according to the resource processing indication, to determine a to-be-processed resource; transmitting (203, 403), by the background server, a resource processing request to the second interface in a case that the to-be-processed resource comprises a resource provided by the second cloud service, initiating, by the second interface according to the resource processing request, an authentication request to the authentication server for accessing the resource provided by the second cloud service; performing (204, 404), by the authentication server in response to the authentication request, authentication on accessing the resource provided by the second cloud service, and returning an authentication success message to the second interface in a case that the authentication succeeds; transmitting, by the second interface in response to the authentication success message, a resource processing indication to the background server; and processing, by the background server, the to-be-processed resource in response to the resource processing indication from the second interface, characterized in that the transmitting, by the background server, the resource processing request to the second interface comprises: transmitting, by the background server to the second interface, the resource processing request carrying signature information of the first cloud service, and information about the resource comprised in the to-be-processed resource and provided by the second cloud service; the initiating, by the second interface to the authentication server according to the resource processing request, the authentication request used for accessing the resource provided by the second cloud service comprises: initiating, by the second interface to the authentication server, the authentication request carrying the signature information of the first cloud service, the information about the resource comprised in the to-be-processed resource and provided by the second cloud service, and information about the second interface; and the performing, by the authentication server in response to the authentication request, the authentication on accessing the resource provided by the second cloud service comprises: performing, by the authentication server according to the information carried in the authentication request, the authentication on accessing the resource provided by the second cloud service. obtaining, by the background server, a resource processing indication from the first interface; performing (202, 402), by the background server, identification according to the resource processing indication, to determine a to-be-processed resource; transmitting (203, 403), by the background server, a resource processing request to the second interface in a case that the to-be-processed resource comprises a resource provided by the second cloud service, initiating, by the second interface according to the resource processing request, an authentication request to the authentication server for accessing the resource provided by the second cloud service; performing (204, 404), by the authentication server in response to the authentication request, authentication on accessing the resource provided by the second cloud service, and returning an authentication success message to the second interface in a case that the authentication succeeds; transmitting, by the second interface in response to the authentication success message, a resource processing indication to the background server; and processing, by the background server, the to-be-processed resource in response to the resource processing indication from the second interface, characterized in that the transmitting, by the background server, the resource processing request to the second interface comprises: transmitting, by the background server to the second interface, the resource processing request carrying signature information of the first cloud service, and information about the resource comprised in the to-be-processed resource and provided by the second cloud service; the initiating, by the second interface to the authentication server according to the resource processing request, the authentication request used for accessing the resource provided by the second cloud service comprises: initiating, by the second interface to the authentication server, the authentication request carrying the signature information of the first cloud service, the information about the resource comprised in the to-be-processed resource and provided by the second cloud service, and information about the second interface; and the performing, by the authentication server in response to the authentication request, the authentication on accessing the resource provided by the second cloud service comprises: performing, by the authentication server according to the information carried in the authentication request, the authentication on accessing the resource provided by the second cloud service.
