Drogue IoT HTTP Client
An HTTP client for embedded systems, based on drogue-network.
It is intended to be used in a #![no_std]
environment, without an allocator.
To Do
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.
Example
const ENDPOINT: &'static str = "my-host";
fn send() -> Result<(),()> {
let mut tcp = TcpSocketSinkSource::from(network, socket);
let con = HttpConnection::<U1024>::new();
let data = r#"{"temp": 1.23}"#;
let handler = BufferResponseHandler::<U1024>::new();
let mut req = con
.post("/publish/telemetry")
.headers(&[("Host", ENDPOINT), ("Content-Type", "text/json")])
.handler(handler)
.execute_with::<_, consts::U512>(&mut tcp, Some(data.as_bytes()));
tcp.pipe_data(&mut req)
.map_err(|_| ThingError::FailedToPublish)?;
let (con, handler) = req.complete();
log::info!(
"Result: {} {}, Payload: {:?}",
handler.code(),
handler.reason(),
from_utf8(handler.payload())
);
}
