This module is a drop-in replacement for Garry's Mod's HTTP function, inspired by gmsv_chttp created by timschumi.

The module uses the reqwest crate for dispatching HTTP requests, tokio crate for async/thread scheduling runtime and the rustls crate for SSL/TLS.

This module was written in Rust and serves as a decent example on how to write a Garry's Mod binary module in Rust. (Thank you Willox for the base!)

Download the relevant module for your server's operating system and platform/Gmod branch from the releases section.

Drop the module into garrysmod/lua/bin/ in your server's files. If the bin folder doesn't exist, create it.

If you're not sure on what operating system/platform your server is running, run this in your server's console:

lua_run print((system.IsWindows()and"Windows"or system.IsLinux()and"Linux"or"Unsupported").." "..(jit.arch=="x64"and"x86-64"or"x86"))

To use reqwest in your addons, you can put this snippet at the top of your code, which will fallback to Gmod's default HTTP function if reqwest is not installed on the server.

if pcall(require, "reqwest") and reqwest ~= nil then
    my_http = reqwest
else
    my_http = HTTP
end

To add custom root certificates, place them in the "garrysmod/tls_certificates" directory. The certificates must be X509 and encoded in either pem or der. They must also end in the .pem or .der file extensions respective to their econding. If there is a problem loading the certificate, it'll be skipped over and a message will be displayed in the console.
