Document use of TLS with RSocket

See original GitHub issue

Sample project available on Github: https://github.com/codependent/rsocket-tls/

The full context of this problem can be found on StackOverflow.

The problem is that without TLS on the server/client, the communication works perfectly, but after securing them it fails.

Here’s the full server and client code:

import reactor.netty.tcp.TcpServer
import java.io.File
import java.util.concurrent.CountDownLatch

I’ve searched everywhere for a TLS RSocket example but found nothing. Also the docs don’t show anything in this regard so I’m not sure whether I’m doing something wrong or there’s an actual problem when using TLS.

We have some examples now https://github.com/rsocket/rsocket-java/blob/c80b3cb6437046f3ccc79136a66299448f58c561/rsocket-transport-netty/src/test/java/io/rsocket/transport/netty/TcpSecureTransportTest.java

After upgrading to RC7 and replacing the deprecated classes the sample started working:

Server:

    val latch = CountDownLatch(1)
    
    RSocketServer.create()
        .payloadDecoder(PayloadDecoder.DEFAULT)
        .acceptor { setup, sendingSocket ->
            Mono.just(
                object : AbstractRSocket() {
                    override fun requestStream(payload: Payload): Flux<Payload> {
                        val randomNumberGenerator = Random(1234)
                        val numbers = payload.dataUtf8.toInt()
                        println("Generating $numbers random numbers")
                        return IntRange(1, numbers)
                            .map { DefaultPayload.create(randomNumberGenerator.nextUInt().toString().toByteArray()) }
                            .toList().toFlux()
                    }
                })
        }.bind(
            TcpServerTransport.create(TcpServer.create().port(7878)
                .secure {
                    it.sslContext(
                        SslContextBuilder.forServer(
                            File(RequestStreamRSocketServer::class.java.getResource("certificate.pem").toURI()),
                            File(RequestStreamRSocketServer::class.java.getResource("key.pem").toURI())
                        )
                    )
                })
        )
        .block()

    latch.await()

Client:

    val latch = CountDownLatch(1)

    val client = RSocketConnector.connectWith(
        TcpClientTransport.create(TcpClient.create().port(7878)
            .secure {
                it.sslContext(
                    SslContextBuilder.forClient().trustManager(
                        File(
                            RequestStreamRSocketClient::class.java.getResource(
                                "certificate.pem"
                            ).path
                        )
                    )
                )
            })
    ).block()!!

    client.requestStream(DefaultPayload.create("10"))
        .map { it.dataUtf8 }
        .doOnNext(System.out::println)
        .doOnComplete { latch.countDown() }
        .doOnError { it.printStackTrace() }
        .subscribe()

    latch.await()
