Delphi Cookbook - Second Edition

By: Daniele Teti

Overview of this book

Delphi is a cross-platform Integrated Development Environment (IDE) that supports rapid application development for Microsoft Windows, Apple Mac OS X, Google Android, and Apple iOS. It helps you to concentrate on the real business and save yourself the pain of wandering amid GUI widget details, or having to tackle inter-platform incompatibilities. It also has a wide range of drag-and-drop controls, helping you code your business logic into your business model, and it compiles natively for desktop and mobile platforms. This book will teach you how to design and develop applications, deploy them on the cloud platform, and distribute them within an organization via Google Play and other similar platforms. You will begin with the basics of Delphi and get acquainted with JSON format strings, XSLT transformations, unicode encodings and various types of streams. We then move on to more advanced topics such as developing higher-order functions and using enumerators and RTTI. You will get an understanding of how Delphi RTL functions and how to use FireMonkey in a VCL application. We will then cover topics such as multithreading, using the parallel programming library and putting Delphi on a server. We will also take a look at the new feature of WebBroker Apache modules and then ride the mobile revolution with FireMonkey. By the end of the book, you will be able to develop and deploy cross-platform applications using Delphi .

Consuming RESTful services using native HTTP(S) client libraries


We live in an interconnected world! A lot of applications now have to exchange data with remote systems. One of the most commonly used and powerful mechanisms to define a communication interface between software over the Internet are RESTful web services (more information about REST and RESTful interfaces will be provided in Chapter 6, Put Delphi on the Server, in the recipe Implementing a RESTful interface using WebBroker). Usually in Delphi, you can use the INDY suite to access HTTP servers. When dealing with HTTPS, INDY produces some headaches because it doesn't use the same SSL layer of the operating systems, but relies on OpenSSL libraries, so you have to provide a specific version of OpenSSL for each different OS your application supports and you cannot benefit from the security updates from the OSes vendor. This has been a just-to-keep-in-mind problem up to April 7, 2014, when the Heartbleed security bug has been disclosed...
