带有 jwt 授权的 Spring Boot 4.3.5 WebSocket 聊天。 GenericMessage 中没有目的地

Question

我正在尝试为带有 spring boot 后端的移动应用程序(ionic 3)实现 1-1 聊天。似乎遇到了一些配置问题。

无法发送消息可能是因为没有创建目标 channel

后端:

聊天 Controller :

@RestController
public class ChatController {
    @Autowired
    private PrivateChatService privateChatService;

    private final static Logger logger = LogManager.getLogger(ChatController.class.getName());


    @RequestMapping(value = "/chat/messages/{item_id}/chat_with/{buyer_login}", method = RequestMethod.GET, produces = "application/json")
    public ResponseEntity<String> getExistingChatMessages(@PathVariable("item_id") String itemId, @PathVariable("buyer_login") String buyerLogin) {
        List<ChatMessage> messages = privateChatService.getExistingChatMessages(itemId, buyerLogin);

        logger.info("Here get messages");
        return JSONResponseHelper.createResponse(messages, HttpStatus.OK);
    }


    @MessageMapping("/chat/{item_id}/send")
    @SendTo("/topic/chat/{item_id}/chat_with/{buyer_login}")
    public ChatMessage send(@Payload ChatMessage message,
                            @DestinationVariable("item_id") String item_id) throws Exception {
//        logger.info(principal.getName());
        logger.info(message.toString());
        logger.info(item_id);
        privateChatService.submitMessage(message);
        return message;
    }

}

WebSocketConfig:

@Configuration
@EnableWebSocketMessageBroker
@Order(Ordered.HIGHEST_PRECEDENCE + 99)
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    private final static Logger logger = LogManager.getLogger(WebSocketConfig.class.getName());

    @Autowired
    private JwtTokenProvider jwtTokenProvider;

    @Autowired
    private PrivateChatService privateChatService;

    private static final String MESSAGE_PREFIX = "/topic";
    private static final String END_POINT = "/chat";
    private static final String APPLICATION_DESTINATION_PREFIX = "/live";


    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        if (registry != null) {
            registry.addEndpoint(END_POINT).setAllowedOrigins("*").withSockJS();
        }
    }

    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        if (registry != null) {
            registry.enableSimpleBroker(MESSAGE_PREFIX);
            registry.setApplicationDestinationPrefixes(APPLICATION_DESTINATION_PREFIX);
        }
    }

    @Override
    public void configureClientInboundChannel(ChannelRegistration registration) {
        registration.setInterceptors(new ChannelInterceptorAdapter() {

            @Override
            public Message<?> preSend(Message<?> message, MessageChannel channel) {
                StompHeaderAccessor accessor = MessageHeaderAccessor.getAccessor(message, StompHeaderAccessor.class);

                if (StompCommand.CONNECT.equals(accessor.getCommand())) {
                    String authToken = accessor.getFirstNativeHeader("Authentication");
                    String jwt = JwtUtils.resolveToken(authToken);
                    if (jwtTokenProvider.validateToken(jwt)) {
                        Authentication authentication = jwtTokenProvider.getAuthentication(jwt);
                        accessor.setUser(authentication);
                        String itemId = accessor.getFirstNativeHeader("item_id");
                        accessor.setDestination("/topic" + privateChatService.getChannelId(itemId, authentication.getName()));
                        logger.info(accessor.getDestination()); //ex: /topic/chat/3434/chat_with/user3797474342423
                    }
                }
                return message;
            }
        });
    }
}

WebSocketSecurityConfig

@Configuration
public class WebSocketSecurityConfig extends AbstractSecurityWebSocketMessageBrokerConfigurer {
    @Override
    protected boolean sameOriginDisabled() {
        return true;
    }
}

移动客户端，ng2-stomp-service:

 private _initWebsock(auth_token:string, item_id: number) {
    let headers: Object = {
      Authentication: `Bearer ${auth_token}`,
      item_id: item_id
    };

    this.stomp.configure({
      host :this.websocketApi + 'chat',
      headers: headers,
      queue:{'init':false}
    });

    console.log("Connecting stomp socket...");

    //start connection
    this.stomp.startConnect().then(() => {
      this.stomp.done('init');
      console.log('connected');

      //subscribe
      this.subscription = this.stomp.subscribe(`/chat/${item_id}/`, this.socketListener);
    });
  }
  public socketListener = (data) => {
    console.log(data)
  };

  send(msg: ChatMessage, item_id: number){
    //send data

    console.log(msg);
    this.stomp.send(`/live/chat/${item_id}/send`, {}, JSON.stringify(msg));
  }

问题 1(可能):

在浏览器控制台中，它显示客户端订阅 /chat/item_id 而不是 /topic/chat/3434/chat_with/user3797474342423 => 看起来像 configureClientInboundChannel 不起作用？

问题 2:

当尝试执行 this.stomp.send(/live/chat/${item_id}/send, {}, JSON.stringify(msg)); , 得到o.s.m.s.b.DefaultSubscriptionRegistry : GenericMessage [payload=byte[2], headers={simpMessageType=MESSAGE.... 错误。

Answer 1

https://stackoverflow.com/a/33962402/8336511

这就是我解决这个问题的方法:

When user authenticates with Spring Security, WebSocket module creates unique channel for that user based on his Principal. Example "/user/queue/position-updates" is translated to "/queue/position-updates-user123"

So on the client side all I had to do, was subscribe to /user/queue/requests

And on the server side, send messages to /user/{username}/queue/requests with convertAndSendToUser(request.getFromUser(), "/queue/requests", request) and Spring handles the rest.
