Scanner web service for web application and scanner driver communication
View Patent ↗A computer system with a scanner web service set up as a local host is provided. An HTTP message is received from a client-side web application code client-side running in a web browser on the computer system by the scanner web service. A message based on the received HTTP message is sent to a scanner driver that is in communication with a scanner connected to or integrated with the computer system. Scanned image information is received from the scanner driver, and is provided to the client-side web application code running the web browser.
1. A computer system, comprising:
a processor configured to:
receive from a client-side web application code running in a web browser on the computer system an HTTP message to a scanner web service;
generate a message based at least in part on the HTTP message;
send the generated message to a scanner driver, wherein the scanner driver is in communication with a scanner connected to the computer system;
receive the scanned image information from the scanner driver; and
provide the scanned image information to the client-side web application code running in the web browser; and
a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions.
2. The system as in claim 1 , wherein the client-side web application code establishes a connection with the scanner web service by searching through a list of ports on the local host.
3. The system as in claim 1 , wherein the client-side web application code establishes a connection with the scanner web service by receiving a start scan session HTTP message from the client-side web application code.
4. The system as in claim 3 , wherein the start a scan session HTTP message includes an application identifier.
5. The system as in claim 1 , wherein the client-side web application code is written in browser executable code.
6. The system as in claim 1 , wherein the client-side web application code is written using a web application framework.
7. The system as in claim 1 , wherein the client-side web application code uses an add-on library to generate HTTP messages to the scanner web service.
8. The system as in claim 1 , wherein the processor is further configured to store the scanned image information from the scanner driver to local storage.
9. The system as in claim 1 , wherein the HTTP message is sent over a secure HTTP connection from the client-side web application code to the scanner web service.
10. The system as in claim 1 , wherein providing the scanned image information to the client-side web application code comprises providing scanned image information in JSON format.
11. The system as in claim 1 , further comprising encoding the scanned image information.
12. The system as in claim 1 , wherein the scanned image information comprises image data and image metadata.
13. The system as in claim 1 , wherein the scanned image information comprises a stream object.
14. The system as in claim 1 , wherein if the scanner web service is receiving the HTTP message from the client-side web application code for a first time to access the scanner connected to the computer system, then providing a pop-up message to receive user confirmation to allow the client-side web application code to use the scanner.
15. The system as in claim 1 , wherein the scanner driver is an ISIS scanner driver.
16. The system as in claim 1 , wherein the scanner driver is a TWAIN scanner driver.
17. The system as in claim 1 , wherein the message to the scanner driver comprises a message to open a configuration settings GUI (Graphical User Interface), and receiving scanner configuration settings from the GUI.
18. The system as in claim 1 , wherein the client-side web application code receives the scanned image information from the scanner web service and sends the scanned image information to a server.
19. A method comprising:
providing a scanner web service set up as a local host on a computer system, wherein the scanner web service is configured to:
receive from a client-side web application code running in a web browser on the computer system an HTTP message to the scanner web service;
generate a message based at least in part on the HTTP message;
send the generated message to a scanner driver, wherein the scanner driver is in communication with a scanner connected to the computer system;
receive the scanned image information from the scanner driver; and
provide the scanned image information to the client-side web application code running in the web browser.
20. A computer program product, the computer program product being embodied in a tangible non-transitory computer readable storage medium and comprising computer instructions for:
providing a scanner web service set up as a local host on a computer system;
receiving at the scanner web service, from a client-side web application code running in a web browser on the computer system, an HTTP message to the scanner web service, wherein the scanner web service only accepts HTTP messages from the computer system;
generating a message based at least in part on the HTTP message;
sending the generated message to a scanner driver, wherein the scanner driver is in communication with a scanner connected to the computer system and is configured to get scanned image information from the scanner at least in part in response to the generated message;
receiving the scanned image information from the scanner driver; and
providing the scanned image information to the client-side web application code running in the web browser.
