问题
I'm using stomp.js over SockJS in my javascript client. I'm connecting to websocket using
stompClient.connect({}, function (frame) {
stomp over sockJS connection has 2 http requests:
- request to /info
- http upgrade request
the client sends all cookies. I would like to also send custom headers (e.g. XSRF header) but didn't find a way to do that. Will appreciate any help.

@Rohitdev So basically you can't send any HTTP headers using stompClient, because STOMP is layer over websockets, and only when websockets handshake happen we have possibility to send custom headers. So only SockJS can send this headers, but for some reasons don't do this: https://github.com/sockjs/sockjs-client/issues/196
回答2:
Custom headers:
stompClient.connect({token: "ABC123"}, function(frame) { ... code ...});
Without Custom headers:
stompClient.connect({}, function(frame) { ... code ...});
In Javascript, you can extract an STOMP header using:
username = frame.headers['user-name'];
In the server side, if you are using Spring Framework you can implementa an Interceptor to copy the HTTP parmeters to WebSockets STOMP headers.
public class HttpSessionHandshakeInterceptor_personalised implements HandshakeInterceptor {
@Override
public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response,
WebSocketHandler wsHandler, Map<String, Object> attributes) throws Exception {
// Set ip attribute to WebSocket session
attributes.put("ip", request.getRemoteAddress());
// ============================================= CODIGO PERSONAL
ServletServerHttpRequest servletRequest = (ServletServerHttpRequest) request;
HttpServletRequest httpServletRequest = servletRequest.getServletRequest();
// httpServletRequest.getCookies();
// httpServletRequest.getParameter("inquiryId");
// httpServletRequest.getRemoteUser();
String token = httpServletRequest.getParameter("token");
...
}
}
And for send messages without STOMP parameters:
function sendMessage() {
var from = document.getElementById('from').value;
var text = document.getElementById('text').value;
stompClient.send("/app/chatchannel", {},
JSON.stringify({'from':from, 'text':text}));
}
and here you are passing parameters into the STOMP headers.
function sendMessage() {
var from = document.getElementById('from').value;
var text = document.getElementById('text').value;
stompClient.send("/app/chatchannel", {'token':'AA123'},
JSON.stringify({'from':from, 'text':text}));
}
回答3:
Use @Header(name = "token")
annotation inside the method if you are using Spring boot at the server.
Usage -
@Controller
public class SocketController {
static final String token = "1234";
@MessageMapping("/send")
@SendTo("/receive/changes")
public Object notify(MessageModel message, @Header(name = "token") String header)throws Exception {
if(!header.equals(token)) {
// return when headers do not match
return("Unauthorized");
}
// return the model object with associated sent message
return new MessageModel(message.getMessage());
}
}
You should have a MessageModel
class with message
variable and required getters
, setters
and contructor
.
In frontend use Stomp
Usage -
function sendMessage() {
var text = document.getElementById('text').value;
stompClient.send("/send/message", {'token':'1234'},
JSON.stringify({'message':text}));
}
To add more security you an use CORS in Spring
