How to get the remote host from a rsocket

Question

I now receive an rsocket connection in my spring project, and then I want to get its remote address and port, how should I get it?Similar to using socket.getRemoteSocketAddress() to get the remote address of the socket.

@ConnectMapping
public void connectMapping(RSocketRequester requester) {
    // there is a resockt connect, how can i get the remote host from it
    RSocket rSocket = requester.rsocket();
    // TODO
    logger.info("host port");
}

like the socket.getRemoteSocketAddress(),i want to get the remote host from a rsocket — Yu Wang, Mar 03 '21 at 04:19

Unfortunately, I think even if you grab the RSocketRequester in @ConnectMapping or @MessageMapping method it is an internal detail. io.rsocket.core.RSocketRequester via RequesterResponderSupport holds the DuplexConnection which represents a connection over tcp, web socket or in-process. It is not exposed via a public API.

This is a worthy request but you will need to file a feature request to get this added unless I'm missing something obvious.

It isn't clear that there is a hook in https://docs.spring.io/spring-boot/docs/2.3.0.RELEASE/api/org/springframework/boot/rsocket/server/RSocketServerCustomizer.html to let you see the DuplexConnection (tcp or web socket etc) as it's established.

Thank you for your answer! Indeed, as you answered, the connected information is protected. It would be troublesome if I want to check the remote address. — Yu Wang, Mar 03 '21 at 11:02
