Simple and lightweight HTTP client for the low level wasmedge_wasi_socket library. It is to be compiled into WebAssembly bytecode targets and runs in the WasmEdge Runtime as a lightweight and secure alternative to natively compiled apps in Linux container.
This project is forked and derived from the http_req project created by jayjamesjay.
Basic GET request in HTTPS
use http_req::request;
fn main() {
let mut writer = Vec::new(); //container for body of a response
let res = request::get("https://httpbin.org/get?msg=WasmEdge", &mut writer).unwrap();
println!("Status: {} {}", res.status_code(), res.reason());
println!("Headers {}", res.headers());
println!("{}", String::from_utf8_lossy(&writer));
