Vsevolod Leonov from Embarcadero is on a roll with a second blog post about building a DataSnap client and server (read about the other post). In this blog post Vsevolod shows how to send an object from a mobile DataSnap client using Delphi XE5 Firemonkey to a DataSnap server. DataSnap automatically serializes the object as JSON on the client and deserializes it again on the server. Additionally, he covers how to use Codesite Express to view the data that is being transferred between the two using the CodeSite Live Viewer. First he creates a custom object class called TMyObject which has some values in it. Next he creates a function to send the object from the client to the server. And finally he sends the object from the server to the CodeSite Live Viewer. I recommend doing your debug and testing with a Win32 DataSnap server and then switching to an ISAPI for production. The DataSnap client should work on both Android and IOS (as well as Windows and OSX). The post is in Russian so I’ve run the link through Google Translate. Here is a sample function from his project:
procedure TForm2. Button3Click (Sender: TObject);
var
MyObject: TMyClass;
begin
MyObject: = TMyClass. Create;
MyObject. A: = 777;
MyObject. B: = 3.1415926;
ClientModule1. ServerMethods1Client. LogObject (MyObject);
end;
