Communication with external REST

[uniguisyriusz]

I want to communicate with external REST to synchronize (bidirectional) data between UniGUI App database and windows apps database. REST is directly connected with windows app database. In UniGUI app i will make a form with button, on button click I will call REST and save readed data to database. It is possible to fire this action without entering webbrowser and manually click button? For example via URL? This would help to make data synchronization automatic.

 

Mayby someone can propose other way to do this?

Boa tarde,

   é possivel fazer isso com o RestClient + TTimer, você pode implementar no Unigui.

Dá uma olhada no (REST Demo do Delphi).

You can use the "OnHTTPCommand" event in the UniServerModule.

procedure TUniServerModule.UniGUIServerModuleHTTPCommand(ARequestInfo: TIdHTTPRequestInfo;
  AResponseInfo: TIdHTTPResponseInfo; var Handled: Boolean);
var
  RC : TRESTClient;

begin
  RC := TRESTClient.Create;
  try
    if ARequestInfo.URI='/data/synchronizer' then
    begin
      // DO YOUR REST STUFF

      AResponseInfo.ResponseNo := 200;
      AResponseInfo.ContentText := 'Synchronization done!';
      Handled := True;
    end;
  finally
    RC.Free;
  end;
end;

You can then call it like this:

 

...localhost:8077/data/synchronizer

      AResponseInfo.ResponseNo := 200;
      AResponseInfo.ContentText := 'Synchronization done!';
      AResponseInfo.WriteContent;
      Handled := True;
    end;
  finally
    RC.Free;
  end;
end;

...localhost:8077/data/synchronizer

Is this UniGUIServerModuleHTTPCommand like having webbroker inside unigui app? Does it creates a thread for each request?

[GerhardV]

The UniGUI server is based on Indy's HTTP server, so yes it would create a thread for each request but the request is not associated with any session.

 

Also please take note that there is no security in the above example, you would need to implement some authentication mechanism yourself.

 

Farshad please correct me if I am wrong.
