Abstract: Implementations of the present specification recite DOI scanning-based information apparatuses, methods, and devices. In one implementation, a method includes: scanning, by a user device, a digital object identifier (DOI); based on scanning the DOI, obtaining service information encoded in the DOI; caching the service information within memory of the user device; generating a first service request based on the service information cached within the memory of the user device; sending the first service request to a service server; determining non-receipt of a service response from the service server within a predetermined time duration following the sending of the first service request; responsive to determining the non-receipt of the service response from the service server within the predetermined time duration, generating a second service request based on the service information cached within the memory of the user device; and sending the second service request to the service server.

Abstract: Implementations of the present specification disclose DOI scanning-based information processing methods, apparatuses, and devices. After an end-user device scans a DOI and obtains service information corresponding to the DOI, the end-user device can cache the service information. Thereafter, the end-user device can read the cached service information, to generate a service request and send the service request to a service server. Particularly, when a network connection between the end-user device and the service server is abnormal, the end-user device can independently retry the service request based on the cached service information.
