@@ -32,14 +32,70 @@ Das System bietet folgende STOMP-Funktionalitäten:
```javascript
// Mit SockJS
const socket = new SockJS('http://localhost:8080/ws');
const socket = new SockJS('http://192.168.180.196:8080/ws');
const stompClient = Stomp.over(socket);

// Oder mit nativem WebSocket (WICHTIG: ws:// verwenden, nicht http://)
const socket = new WebSocket('ws://192.168.180.196:8080/websocket');
const stompClient = Stomp.over(socket);
```
### Flutter/Dart STOMP Client
**Für Flutter-Apps verwenden Sie diese Konfiguration:**
```dart
import 'package:stomp_dart_client/stomp.dart';
import 'package:stomp_dart_client/stomp_config.dart';
import 'package:stomp_dart_client/stomp_frame.dart';
import 'dart:convert';
// WICHTIG: Verwenden Sie ws:// für WebSocket-Verbindungen, NICHT http://
final stompClient = StompClient(
config: StompConfig(
url: 'ws://192.168.180.196:8080/websocket', // Beachten Sie ws:// statt http://
onConnect: onConnectCallback,
onWebSocketError: (dynamic error) => print('WebSocket Error: $error'),
onStompError: (StompFrame frame) => print('Stomp Error: ${frame.body}'),
onDisconnect: (StompFrame frame) => print('Disconnected'),
// Heartbeat-Konfiguration
heartbeatIncoming: Duration(seconds: 20),
heartbeatOutgoing: Duration(seconds: 20),
),
);
void onConnectCallback(StompFrame frame) {
print('Connected to STOMP server');
// Nachrichten abonnieren
stompClient.subscribe(
destination: '/topic/messages',
callback: (StompFrame frame) {
print('Received message: ${frame.body}');
},
);
}
// Verbindung herstellen
stompClient.activate();
// Nachricht senden
void sendMessage(String content) {
stompClient.send(
destination: '/app/message',
body: jsonEncode({
'content': content,
'sender': 'FlutterApp',
}),
);
}
```
**Alternative Endpunkte für Flutter:**
Falls Probleme mit `/websocket` auftreten, versuchen Sie:
- `ws://192.168.180.196:8080/stomp` (zusätzlicher Endpunkt)
- `ws://192.168.180.196:8080/ws` (SockJS-Endpunkt ohne SockJS-Protokoll)
### 2. Verbindung herstellen
