This way, a JSON array with embedded array data can be passed with a single API call. The nice thing with a single TRESTRequest, is that it can be used to feed into multiple TRESTResponseDataSetAdapters. Working with Detail in JSON Data Array using TRESTResponseDataSetAdapter

If you need Strings larger than 255 char, then you would want to update the StringFieldSize property (or the specific field defs for a certain string). If you execute the TRESTRequest (right click on the component) inside the RAD Studio IDE, you can then auto-populate the field defs in the TDataSet based on the returned data. If none are defined, it creates a set of String fields. The TRESTResponseDataSetAdapter takes the JSON content from the TRESTRequest, and converts it into a TDataSet, based on the FieldDefs defined. Using the TRESTResponse component, it is possible to take the JSON array data and convert it into a TDataSet using the TRESTResponseDataSetAdapter. Watch – Using the Rest Debugger Converting JSON into a TDataSet on the client side Once running you can then test the end point and use the REST Debugger to check its working before copying the configuration into a set of components that can be used inside your application.

( See how to add The REST Debugger into the IDE Tools menu) Using this, you can then “copy components” to paste into your application the components required, all pre-configured. You can define user security, end points, resources, parameters etc all in the GUI. The RESTDebugger is an application (in RADStudio /bin directory) that can be used to rapidly connect to a REST end point. I have previously covered how to use the TRESTClient to connect to MailChimp and also Azure Translation Services, so I wont go over the basis of these components here, but I will quickly expand on the REST Debugger and how useful it is to get started.

The units all appear as part of the REST name space, enabling common native code to be written to run over Windows, macOS, Linux, iOS and Android. To connect rapidly to a REST resource, there are a set of components available in Delphi / C++Builder that work across VCL (Windows) and FMX (multi-platform) applications.

Enabling the data in the UI with LiveBindings and zero code.Ĭonnecting to a REST resource in a client.

Converting the JSON into a master detail datasets (based on the current item in the JSON data).

Setting up components to connect to the REST API.

The video and supporting blog post take you through the following. – It’s now time to consume the API into a cross platform Delphi Client.

If you have not read and watch the videos. In my last two posts, we have created a REST server with a fully documented API using YAML , and exposed 3 datasets with master detail relationships over REST using zero lines of code.

This is part 3 in my series of developing an REST server and client application and will focus around using the TRESTResponseDataSetAdapter.
