I have a Websocket Stomp server built in Java (Spring based). My JavaScript client is able to talk to the server using Stomp over Web Socket - no issues.
I'm trying to use the WebSocket4Net library to build the C# client. Can anyone please tell me how can I build the Stomp message frames in bytes[] and send them to the server?
In the OnOpen() method, I'm doing the following:
String stompMsg = "CONNECT\n";
stompMsg += "accept-version:1.1,1.2\n\n";
stompMsg += "^@";
Byte[] bytesToSend = Encoding.UTF8.GetBytes(stompMsg);
websocketObj.Send(bytesToSend, 0, bytesToSend.Length);
I get the following message from server:
Failed to parse BinaryMessage payload - java.nio.HeapByteBuffer. Sending STOMP ERROR to client.
java.lang.IllegalArgumentException: Object of class [org.springframework.web.socket.BinaryMessage] must be an instance of class org.springframework.web.socket.TextMessage at org.springframework.util.Assert.isInstanceOf(Assert.java:339) at org.springframework.util.Assert.isInstanceOf(Assert.java:319) at org.springframework.web.socket.messaging.StompSubProtocolHandler.handleMessageFromClient(StompSubProtocolHandler.java:189) at org.springframework.web.socket.messaging.SubProtocolWebSocketHandler.handleMessage(SubProtocolWebSocketHandler.java:307) at org.springframework.web.socket.handler.WebSocketHandlerDecorator.handleMessage(WebSocketHandlerDecorator.java:75) at org.springframework.web.socket.handler.LoggingWebSocketHandlerDecorator.handleMessage(LoggingWebSocketHandlerDecorator.java:55) at org.springframework.web.socket.handler.ExceptionWebSocketHandlerDecorator.handleMessage(ExceptionWebSocketHandlerDecorator.java:71) at org.springframework.web.socket.adapter.standard.StandardWebSocketHandlerAdapter.handleBinaryMessage(StandardWebSocketHandlerAdapter.java:122) at org.springframework.web.socket.adapter.standard.StandardWebSocketHandlerAdapter.access$100(StandardWebSocketHandlerAdapter.java:42) at org.springframework.web.socket.adapter.standard.StandardWebSocketHandlerAdapter$4.onMessage(StandardWebSocketHandlerAdapter.java:88) at org.springframework.web.socket.adapter.standard.StandardWebSocketHandlerAdapter$4.onMessage(StandardWebSocketHandlerAdapter.java:85) at org.apache.tomcat.websocket.WsFrameBase.sendMessageBinary(WsFrameBase.java:549) at org.apache.tomcat.websocket.WsFrameBase.processDataBinary(WsFrameBase.java:514) at org.apache.tomcat.websocket.WsFrameBase.processData(WsFrameBase.java:274) at org.apache.tomcat.websocket.WsFrameBase.processInputBuffer(WsFrameBase.java:116) at org.apache.tomcat.websocket.server.WsFrameServer.onDataAvailable(WsFrameServer.java:54) at org.apache.tomcat.websocket.server.WsHttpUpgradeHandler$WsReadListener.onDataAvailable(WsHttpUpgradeHandler.java:192) at org.apache.coyote.http11.upgrade.AbstractServletInputStream.onDataAvailable(AbstractServletInputStream.java:178) at org.apache.coyote.http11.upgrade.AbstractProcessor.upgradeDispatch(AbstractProcessor.java:92) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:601) at org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.doRun(AprEndpoint.java:2430) at org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:2419) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744)
Can anyone please suggest if you have successfully created / used any C# client library with a spring based STOMP over Web Socket server?
@Artem - Thank you SO much. The \0 indeed did the trick.
websocket.Send("SUBSCRIBE\nid:sub-0\ndestination:/topic/mytopic\n\n\0");
