How to Send HTTP data in Delphi

[salvi.a 0]

Regards,

I'm new into Delphi and not know much.

 

I'm trying to send data to ESP32 WebServer. My project is simply controlling LEDs by using ESP. So I want to send data like "LED No, R, G, B" or even simply "LED No" to understand how it works. I have found a color picker on the internet.

 

Using ESP on Station Point. So IP address is certain and won't be changed. What should I take a look at?

Delphi ships with Indy pre-installed, which has a TIdHTTP component.  Modern versions of Delphi also have native THTTPClient/TNetHTTPClient components, too.

 

But either way, you can't just send arbitrary data to the ESP without understanding what it is actually expecting.  Do you have any documentation on what exactly it actually wants clients to send it?  What do the required URLs look like?  What input parameters are they expecting?  Are they query-string parameters, or post-body parameters?  Etc
