| <h2>Summary</h2> |
| <p> |
| This processor acts as a WebSocket client endpoint to interact with a remote WebSocket server. |
| It is capable of receiving messages from a websocket server and it transfers them to downstream relationships |
| according to the received message types. |
| </p> |
| <p> |
| The processor may have an incoming relationship, in which case flowfile attributes are passed down to its WebSocket Client Service. |
| This can be used to fine-tune the connection configuration (url and headers for example). For example "dynamic.url = |
| currentValue" flowfile attribute can be referenced in the WebSocket Client Service with the ${dynamic.url} expression. |
| </p> |
| <p> |
| You can define custom websocket headers in the incoming flowfile as additional attributes. The attribute key |
| shall start with "header." and continue with they header key. For example: "header.Authorization". The attribute |
| value will be the corresponding header value. If a new flowfile is passed to the processor, the previous sessions will be closed, |
| and any data being sent will be aborted. |
| <ol> |
| <li>header.Autorization | Basic base64UserNamePassWord</li> |
| <li>header.Content-Type | application, audio, example</li> |
| </ol> |
| <p> |
| For multiple header values provide a comma separated list. |
