In this demo, Christophe Flament will demonstrate how to access 4D data via HTTP requests, displaying it using ORDA: collection / object. He will also explain some of the code techniques we can now use with 4D v18 R6.
Using a project database (Library-Demo) adapted from a v17 demo, Christophe will explain how you can display data into a form with a listbox loading it via an HTTP request. This concept is useful, for example, if you want to create a Volume Desktop application that will run independently with no local data/ getting it from the 4D Server via HTTP request calls instead. The same concept is also applicable to PHP code loading the 4D data into a web interface or using the Postman application for testing.
