HTTP requests (without sampfuncs)

Important: from 7/09/2020 update, "HTTP_GET" and "HTTP_POST" have additional parameter called "is_https", which allow it to use https (secure) protocol.
So number of parameters in HTTP_GET and HTTP_POST "0AB1: call_scm_func" opcode calls must be updated (now it's 4 for HTTP_GET instead of 3, and it's 5 instead of 4 for HTTP_POST). If you never used this snippet in the past, please ignore this message (because examples below are updated).

Code to put inside "Gta/cleo/includes/http_requests.txt":

I get this error while running the script:

(I have launched a working http server on localhost but it's not receiving any request)


[23:06:09] Warning(s007): Exception 0xC0000005 at 0x0
[23:06:09] Warning(s007): Exception 0xC0000005 at 0x0

How can I troubleshoot them?

(I have latest cleo version and samp 0.3dl)

I tested it with cleo 4.1, maybe that's the reason but I don't know to be honest

Exactly the same of monday, I didn't change anything.

I created a http_requests.txt in GTA-SanAndreas\CLEO\includes and put

Nice snippet, never liked the idea of external closed source plug-ins like SAMPFUNCS it set's everything on one card.
