Two of my Delphi web service articles have been published in Blaise Pascal Magazine and a third one is coming up.
This series of articles is about writing your own web services server and client in Delphi. The approach of all articles is pragmatic. The first article introduces some of the concepts you need to know and shows you how to create and consume your own web service in Delphi. This second article shows you how to update the data in the web service and how to create in-memory storage for the web service. There is even some JavaScript that shows you how to use the web service from a HTML page.
Creating a web service is a simple and straightforward way to share Delphi application data with third-party software vendors. It’s easy to create one, and it supports the standard features of REST web services with industry standard JSON.
