DOI scanning-based information processing
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.
1. A computer-implemented method, comprising:
scanning, by a user device, a digital object identifier (DOI);
based on scanning the DOI, obtaining, by the user device, service information encoded in the DOI;
caching, by the user device, the service information within memory of the user device;
generating, by the user device, a first service request based on the service information cached within the memory of the user device;
sending, by the user device, the first service request to a service server;
determining, by the user device, non-receipt of a service response from the service server within a predetermined time duration following the sending of the first service request;
in response to determining the non-receipt of the service response from the service server within the predetermined time duration, generating, by the user device, a second service request based on the service information cached within the memory of the user device;
sending, by the user device, the second service request to the service server;
providing, by the user device, a scanning user interface configured to display a retry stop control after sending the second service request to the service server;
receiving user-input indicative of an operation for the retry stop control displayed in the scanning user interface; and
in response to receiving the user-input indicative of the operation for the retry stop control, (i) preventing, by the user device, generation of a third service request and (ii) deleting, by the user device, the service information cached within the memory of the user device.
2. The computer-implemented method of claim 1 , further comprising:
receiving the service response from the service server; and
based on receiving the service response from the service server, preventing generation of the third service request.
3. The computer-implemented method of claim 2 , further comprising:
deleting the service information responsive to receiving the service response from the service server.
4. The computer-implemented method of claim 1 , further comprising:
deleting the service information after a predetermined cache duration.
5. The computer-implemented method of claim 1 , wherein generating the second service request comprises referencing the service information cached within the memory of the user device without additional scanning by the user device.
6. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
scanning, by a user device, a digital object identifier (DOI);
based on scanning the DOI, obtaining, by the user device, service information encoded in the DOI;
caching, by the user device, the service information within memory of the user device;
generating, by the user device, a first service request based on the service information cached within the memory of the user device;
sending, by the user device, the first service request to a service server;
determining, by the user device, non-receipt of a service response from the service server within a predetermined time duration following the sending of the first service request;
in response to determining the non-receipt of the service response from the service server within the predetermined time duration, generating, by the user device, a second service request based on the service information cached within the memory of the user device;
sending, by the user device, the second service request to the service server;
providing, by the user device, a scanning user interface configured to display a retry stop control after sending the second service request to the service server;
receiving user-input indicative of an operation for the retry stop control displayed in the scanning user interface; and
in response to receiving the user-input indicative of the operation for the retry stop control, (i) preventing, by the user device, generation of a third service request and (ii) deleting, by the user device, the service information cached within the memory of the user device.
7. The non-transitory, computer-readable medium of claim 6 , further comprising:
receiving the service response from the service server; and
based on receiving the service response from the service server, preventing generation of the third service request.
8. The non-transitory, computer-readable medium of claim 7 , further comprising:
deleting the service information responsive to receiving the service response from the service server.
9. The non-transitory, computer-readable medium of claim 6 , further comprising:
deleting the service information after a predetermined cache duration.
10. A computer-implemented system, comprising:
one or more computers; and
one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
scanning, by a user device, a digital object identifier (DOI);
based on scanning the DOI, obtaining, by the user device, service information encoded in the DOI;
caching, by the user device, the service information within memory of the user device;
generating, by the user device, a first service request based on the service information cached within the memory of the user device;
sending, by the user device, the first service request to a service server;
determining, by the user device, non-receipt of a service response from the service server within a predetermined time duration following the sending of the first service request;
in response to determining the non-receipt of the service response from the service server within the predetermined time duration, generating, by the user device, a second service request based on the service information cached within the memory of the user device;
sending, by the user device, the second service request to the service server;
providing, by the user device, a scanning user interface configured to display a retry stop control after sending the second service request to the service server;
receiving user-input indicative of an operation for the retry stop control displayed in the scanning user interface; and
in response to receiving the user-input indicative of the operation for the retry stop control, (i) preventing, by the user device, generation of a third service request and (ii) deleting, by the user device, the service information cached within the memory of the user device.
11. The computer-implemented system of claim 10 , further comprising:
receiving the service response from the service server; and
based on receiving the service response from the service server, preventing generation of the third service request.
12. The computer-implemented system of claim 11 , further comprising:
deleting the service information responsive to receiving the service response from the service server.
13. The computer-implemented system of claim 10 , further comprising:
deleting the service information after a predetermined cache duration.
