GoodCam Device Proxy

This library simplifies creating HTTP proxies that can be used to communicate with GoodCam devices in various networks. GoodCam devices contain a built-in client that can be configured to connect automatically to a given proxy. Once connected, the devices will wait for incoming HTTP requests. The proxy simply forwards incoming HTTP requests to the connected devices.

Dependencies

The library requires OpenSSL (version 1.0.1 or newer) or LibreSSL (version 2.5 or newer). Ubuntu/Debian users can install OpenSSL development files using:

sudo apt-get install libssl-dev

Fedora users can install them using:

sudo dnf install openssl-devel

Usage example

See the examples directory in the root of this repository for a ready-to-use example.

use gcdevproxy::{
    async_trait::async_trait,
    auth::BasicAuthorization,
    http::{Body, Request},
    ClientHandlerResult, DeviceHandlerResult, Error, RequestHandler,
};

struct MyRequestHandler;

#[async_trait]
impl RequestHandler for MyRequestHandler {
    async fn handle_device_request(
        &self,
        authorization: BasicAuthorization,
    ) -> Result<DeviceHandlerResult, Error> {
        ...
    }

    async fn handle_client_request(
        &self,
        request: Request<Body>,
    ) -> Result<ClientHandlerResult, Error> {
        ...
    }
}

let mut builder = ProxyBuilder::new();

builder
    .hostname(hostname)
    .http_bind_address(SocketAddr::from((Ipv4Addr::UNSPECIFIED, 8080)));

builder
    .build(MyRequestHandler)
    .await
    .unwrap()
    .await
    .unwrap();
