Interface BasicWebSocketConnector

All Known Implementing Classes:

BasicWebSocketConnectorImpl

public interface BasicWebSocketConnector

A basic connector can be used to configure and open a new client connection. Unlike with WebSocketConnector a client endpoint is not used to consume and send messages.

Quarkus provides a CDI bean with bean type BasicWebSocketConnector and qualifier Default.

This construct is not thread-safe and should not be used concurrently.

Connectors should not be reused. If you need to create multiple connections in a row you'll need to obtain a new connetor instance programmatically using Provider.get():

 import jakarta.enterprise.inject.Instance;

 @Inject
 Instance<BasicWebSocketConnector> connector;

 void connect() {
      var connection1 = connector.get().baseUri(uri)
                  .addHeader("Foo", "alpha")
                  .connectAndAwait();
      var connection2 = connector.get().baseUri(uri)
                  .addHeader("Foo", "bravo")
                  .connectAndAwait();
 }

Method Details

create

static BasicWebSocketConnector create()

Obtains a new basic connector. An alternative to @Inject BasicWebSocketConnector.

Returns:

a new basic connector

baseUri

BasicWebSocketConnector baseUri(URI uri)

Set the base URI.

Parameters:

uri -

Returns:

self

baseUri

default BasicWebSocketConnector baseUri(String baseUri)

Set the base URI.

Parameters:

baseUri -

Returns:

self

path

BasicWebSocketConnector path(String path)

Set the path that should be appended to the path of the URI set by baseUri(URI).

The path may contain path parameters as defined by WebSocketClient.path(). In this case, the pathParam(String, String) method must be used to pass path param values.

Parameters:

path -

Returns:

self

pathParam

BasicWebSocketConnector pathParam(String name,
 String value)

Set the path param.

The value is encoded using URLEncoder.encode(String, java.nio.charset.Charset) before it's used to build the target URI.

Parameters:

name -

value -

Returns:

self

Throws:

IllegalArgumentException - If the path set by path(String) does not contain a parameter with the given name

addHeader

BasicWebSocketConnector addHeader(String name,
 String value)

Add a header used during the initial handshake request.

Parameters:

name -

value -

Returns:

self

See Also:

• HandshakeRequest

addSubprotocol

BasicWebSocketConnector addSubprotocol(String value)

Add the subprotocol.

Parameters:

value -

name -

Returns:

self

executionModel

BasicWebSocketConnector executionModel(BasicWebSocketConnector.ExecutionModel model)

Set the execution model for callback handlers.

By default, BasicWebSocketConnector.ExecutionModel.BLOCKING is used.

Returns:

self

• onTextMessage(BiConsumer)
• onBinaryMessage(BiConsumer)
• onPong(BiConsumer)
• onOpen(Consumer)
• onClose(BiConsumer)
• onError(BiConsumer)

onOpen

Parameters:

consumer -

Returns:

self

See Also:

onTextMessage

BasicWebSocketConnector onTextMessage(BiConsumer<WebSocketClientConnection,String> consumer)

Set a callback to be invoked when a text message is received from the server.

Parameters:

consumer -

Returns:

self

See Also:

• executionModel(ExecutionModel)

onBinaryMessage

BasicWebSocketConnector onBinaryMessage(BiConsumer<WebSocketClientConnection,io.vertx.core.buffer.Buffer> consumer)

• executionModel(ExecutionModel)

onPong

BasicWebSocketConnector onPong(BiConsumer<WebSocketClientConnection,io.vertx.core.buffer.Buffer> consumer)
