I would be happy to contribute working code (server and client) if you like, once I can get the Rust client working.
This is the working C# for the console client:
public class SignalRConnection { public async void Start() { var url = "https://localhost:5001/chathub";
var hubConnection = new HubConnectionBuilder() .WithUrl(url) .WithAutomaticReconnect() .Build(); // Avoid certificate errors for now ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true; // receive a message from the hub hubConnection.On<string, string>("ReceiveMessage", (user, message) => OnReceiveMessage(user, message)); var task = hubConnection.StartAsync(); task.Wait(); // send a message to the hub await hubConnection.InvokeAsync("SendMessage", "ConsoleApp", "Message from the console app"); } private void OnReceiveMessage(string user, string message) { Console.WriteLine($"{user}: {message}"); }}
This is my in-progress but not working Rust "equivalent":
[actix_rt::main]
async fn main() -> io::Result<()> { env_logger::init();
println!("SignalR Console Rust Client");
let url = Url::parse("https://localhost:5001/");
let hub = "chathub"; let handler = Box::new(ChatHubHandler { hub: hub.to_string() });
// Set up the SSL connector so verification can be turned off for now let mut builder = SslConnector::builder(SslMethod::tls()).unwrap(); builder.set_verify(openssl::ssl::SslVerifyMode::NONE); // avoid certificate errors for now let connector = builder.build();
let client = HubClientBuilder::with_hub_and_url(hub, url.unwrap()) .ssl_connector(connector) .start_supervised(handler) .await;
println!("Client started");
match client { Ok(addr) => { addr.do_send(HubQuery::new( hub.to_string(), "SendMessage".to_string(), vec!["Rust Console App"], "Message from the Rust console app".to_string(), )); } Err(e) => { println!("Hub client error : {:?}", e); System::current().stop(); } }
actix_rt::signal::ctrl_c().await
}
I get this output:
SignalR Console Rust Client Client started Hub client error : ParseError(Error("expected value", line: 1, column: 1))
I'd be happy to upload the server code in a PR. It's just the code from Microsoft's SignalR example.
