Chapter 5.7 Web Price Checker

Introduction

The web based price-checker application uses a web-kit library to setup a

browser-like connection to an http server. When an EAN barcode is scanned, the

SG-15

Colour

will send the scanned data as an HTTP request to a web server. The

web serveris responsible for generating the HTML page with Article/Price/Picture

content, which is sent to the SG-15

Colour

. The web-kit utility executing on the

SG-15

Colour

will interpret and show the content on the display.

1. Start Page

Default, the URL of the Start Page and Welcome Page are defined as HTML files

residing on the SG-15

Colour

. The Start page is only displayed at start-up of the Web-

Price-Checker application. Having these files local on the SG-15 guarantees that

the SG-15 starts with a non-empty page (even if the web-server is temporary out

of service). For making the SG-15

Colour

refer to the Start and Welcome page

belonging to the web server demo, change the URLs to

http://192.137.81.60/auth/skweb_start.html and

http://192.137.81.60/auth/skweb_welcome.html

2. Welcome Page

The welcome page shown in between barcode scans when the SG-15

Colour

is in idle

state. The URL may refer to a local file or to an external (web) server.

3. Welcome Timer

After a product scan action and a successful article look-up, the server replies

with an article description, price etc. This information is displayed on the screen

for the number of seconds specified in the Welcome Timer field. When this

timer times out, the SK enters an idle state and normally it will re-display the

Welcome Message, but it is also possible to let the PromoTool application take

over the display from the Price-Checker. For this the skpromo needs to run

simultaneously with skpricechecker, see page DeskTop Configurator.

4. Error Page

The Error Page URL is an option to specify a customized error message.
