WebSocket local event receiver is an internal event receiver that comes with WSO2 products by default. You can configure it with XML, text, and JSON input mapping types.
The websocket-local event receiver should be used if the event source is a web socket client. Such event sources need to connect to the inbuilt websocket server of WSO2 DAS for the DAS to receive events. However, if the event source is a web socket server, the DAS should connect to it in order to receive events. In such scenarios, use the WebSocket Event Receiver.
Creating a WebSocket local event receiver
For instructions on creating a WebSocket local event receiver, see Configuring Event Receivers.
Configuring adapter properties
There are not any adapter-specific properties for the WebSocket local event receiver as shown below.
When multi-tenancy is used, the URL formats used to receive events are as follows.
| Super-tenant/Tenant | URL Formats |
|---|---|
| Super-tenant | ws://localhost:";<DAS_Server_Port>"/inputwebsocket/<receiver_name>wss://localhost:";<DAS_SSL_Server_Port>"/inputwebsocket/<receiver_name>"; |
| Tenant | ws://localhost:";<DAS_Server_Port>"/t/<tenant_domain>/inputwebsocket/<receiver_name>wss://localhost:";<DAS_SSL_Server_Port>"/t/<tenant_domain>/inputwebsocket/<receiver_name>"; |
e.g., If the receiver name is WebSocketLocalInputEventReceiver and the tenant domain is mycompany.com, the URL would be as follows when you use the default server ports.
| Super-tenant/Tenant | URL Formats |
|---|---|
| Super-tenant | ws://localhost:";9763"/inputwebsocket/WebSocketLocalInputEventReceiverwss://localhost:";9443"/inputwebsocket/WebSocketLocalInputEventReceiver"; |
| Tenant | ws://localhost:";9763"/t/mycompany.com/inputwebsocket/WebSocketLocalInputEventReceiverwss://localhost:";9443"/t/mycompany.com/inputwebsocket/WebSocketLocalInputEventReceiver";
