I would like to submit some information collected from user during Inno setup installation to our server via POST.
Obvious solution would be to include an .exe file that the setup would extract into temporary location and launch with parameters. However, I'm wondering - is there is any easier/better way?
Based on jsobo advice of using WinHttp library, I came with this very simple code that does the trick. Say, you want to send serial number for verification just before the actual installation starts. In the code section, put:
procedure CurStepChanged(CurStep: TSetupStep); var WinHttpReq: Variant; begin if CurStep = ssInstall then begin if AutoCheckRadioButton.Checked = True then begin WinHttpReq := CreateOleObject('WinHttp.WinHttpRequest.5.1'); WinHttpReq.Open('POST', '<your_web_server>', false); WinHttpReq.SetRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); WinHttpReq.Send('<your_data>'); // WinHttpReq.ResponseText will hold the server response end; end; end;
Open method takes as arguments the HTTP method, the URL and whether to do async request and it seems like we need to add
SetRequestHeader in order to set the
Content-Type header to
WinHttpReq.Status will hold the response code, so to check if the server returned successfully:
if WinHttpReq.Status <> 200 then begin MsgBox('ERROR', mbError, MB_OK); end else begin MsgBox('SUCCESS', mbInformation, MB_OK); end;

Also, to avoid run-time errors (can happen if the host is unreachable) it is a good idea to surround the code with
