RUSTXY
The Rust Reverse Proxy, build your own reverse proxy in minutes with wonderful features, all customizable.
Example
fn main() {
// Create the address for our proxy server
let address = SocketAddr::from(([0, 0, 0, 0], 8080));
let mut my_proxy = proxy::proxy::Proxy::new(ProxyConfig {
address,
max_connections: 100,
threads: 1,
max_buffer_size: 2048,
});
// set the load balancing algorithm, you can also create your own
my_proxy.set_load_balancer(weighted_least_connections_load_balancer);
// Create a new server
let my_api_server = gateway::server::Server::new(ServerConfig {
id: Uuid::new_v4(), // An internal ID
address: SocketAddr::from(([127, 0, 0, 1], 8081)), // The external service address
accepted_schemes: vec![Scheme::HTTP, Scheme::HTTPS], // The schemas that the server receive
endpoints: Default::default(), // Not useful now, maybe in the future versions
weight: 1, // Weight of the server, useful for the load balancing, more weight = more resources = more assigned requests
});
// Add the server to the proxy
my_proxy.add_server(my_api_server.id.clone(), my_api_server);
// Now lets make some rules for our proxy server
my_proxy.add_forward(ProxyForward {
id: Uuid::new_v4(), // An internal ID
match_headers: None, // Match headers to redirect to this forwarder
match_query: None, // Match query params to redirect to this forwarder
match_method: None, // Match methods to redirect to this forwarder
match_path: Some(vec![ProxyForwardPath {
exactly: false,
starts_with: true,
path: Uri::from_static("/"),
}]), // Match by path to redirect to this forwarder
rewrite_to: None, // Rewrite path for the other side proxy, example the client type: /api and your backend server would receive in /internal-api-xxx
to: vec![
my_api_server.id.clone(),
], // A list of servers to forward the request, useful with load balancing
});
// Start the proxy listening in the provided address
my_proxy.listen()
}
Custom Load Balance
If you need it, you can build with your own criteria load balancer.
my_proxy.set_load_balancer(|proxy_state, forwarder, preselected_servers| {
// proxy_state: internal state of the proxy
// forwarder: the forwarder for the request, selected from matching certain criteria like path, methods or other things
// preselected_servers: the servers that are preselected for the forwarder
// You have to return a server to process the request
// Check in src/proxy/load_balancer.rs for pre-built load balancers
preselected_servers[0].clone()
});
