An HTTP client for embedded systems, based on drogue-network.
It is intended to be used in a #![no_std]
environment, without an allocator.
NOTE: While is says "HTTP", it means "something that, with a bit of luck, could be interpreted as HTTP". It is far from a full HTTP 1.1 client.
~~~rust const ENDPOINT: &'static str = "my-host";
fn send() -> Result<(),()> {
// socket from drogue-network, maybe with TLS let mut tcp = TcpSocketSinkSource::from(network, socket);
let con = HttpConnection::
let data = r#"{"temp": 1.23}"#;
// response implementation with buffer
let handler = BufferResponseHandler::
// create and execute request let mut req = con .post("/publish/telemetry") .headers(&[("Host", ENDPOINT), ("Content-Type", "text/json")]) .handler(handler) .executewith::<_, consts::U512>(&mut tcp, Some(data.asbytes()));
tcp.pipedata(&mut req) .maperr(|_| ThingError::FailedToPublish)?;
let (con, handler) = req.complete();
log::info!( "Result: {} {}, Payload: {:?}", handler.code(), handler.reason(), from_utf8(handler.payload()) );
// you can do the next call with the returned con
}
