This article mainly introduces "how to realize the SocketD protocol message encryption mode". In the daily operation, I believe that many people have doubts about how to realize the SocketD protocol message encryption mode. The editor has consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts of "how to realize the SocketD protocol message encryption mode". Next, please follow the editor to study!

SocketD is a binary point-to-point communication protocol and a new network communication layer 7 protocol. Designed to be used in distributed applications. In this sense, SocketD can be an alternative to other similar protocols such as RSocket. Its message protocol specification has the characteristics of asynchronism, two-way back pressure, multiplexing, disconnection reconnection, message-based and so on. Only Java implementation is provided for the time being, and it is currently used as the sockte channel protocol for Solon rpc.

This case takes a simple message encryption mode as an example: (add encryption demonstration on the basis of message reporting mode)

Server / / start server public class ServerApp {public static void main (String [] args) {/ / launch Solon container (SocketD bean&plugin is managed by solon container) Solon.start (ServerApp.class, args, app-> {app.enableSocketD (true) / / set enhanced protocol and use encryption protocol (also set by client) SocketD.setProtocol (new MessageProtocolSecret () {@ Override public byte [] encrypt (byte [] bytes) throws Exception {return EncryptUtils.aesEncrypt (bytes, "pLft36Ok5zfmP6zI")) } @ Override public byte [] decrypt (byte [] bytes) throws Exception {return EncryptUtils.aesDecrypt (bytes, "pLft36Ok5zfmP6zI");});}) }} / / define server snooping @ ServerEndpointpublic class ServerListener implements Listener {@ Override public void onOpen (Session session) {System.out.println ("there is a client link...") } @ Override public void onMessage (Session session, Message message) {/ / receive the message and do business processing if (message.flag ()! = MessageFlag.heartbeat) {System.out.println ("server: I received a heartbeat");} else {System.out.println ("server: I received:" + message.bodyAsString ()) } client / / launch client public class ClientApp {public static void main (String [] args) throws Throwable {/ / launch Solon container (SocketD bean&plugin is managed by solon container) Solon.start (ClientApp.class, args, app- > {/ / set Enhancement Protocol Use the encryption protocol (also set up by the server) SocketD.setProtocol (new MessageProtocolSecret () {@ Override public byte [] encrypt (byte [] bytes) throws Exception {return EncryptUtils.aesEncrypt (bytes, "pLft36Ok5zfmP6zI") } @ Override public byte [] decrypt (byte [] bytes) throws Exception {return EncryptUtils.aesDecrypt (bytes, "pLft36Ok5zfmP6zI");});}) / / create a session (if the backend is WebSocekt, the protocol header is: ws) Session session = SocketD.createSession ("tcp://localhost:28080"); / / set 30 seconds to automatically send heartbeats (if disconnected, also try automatic heavy link) session.sendHeartbeatAuto (30); / / report message session.send ("Helloworld server!") }} at this point, the study on "how to implement the SocketD protocol message encryption mode" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
