In diesem Fall wird der Funktionsparameter `q` optional, und standardmäßig `None` sein.

/// check

Beachten Sie auch, dass **FastAPI** intelligent genug ist, um zu erkennen, dass `item_id` ein Pfad-Parameter ist und `q` keiner, daher muss letzteres ein Query-Parameter sein.

## Query-Parameter Typkonvertierung

Sie können auch `bool`-Typen deklarieren und sie werden konvertiert:

OkHttp Server-Sent Events
=========================

Experimental support for server-sent events.
API is not considered stable and may change at any time.

## Await for messages and send messages

In your WebSocket route you can `await` for messages and send messages.

```Python hl_lines="48-52"
{!../../docs_src/websockets/tutorial001.py!}
```

You can receive and send binary, text, and JSON data.

## Try it

If your file is named `main.py`, run your application with:

}

// Type - returns type of the target
func (sys *HTTPConsoleLoggerSys) Type() types.TargetType {
	return types.TargetConsole
}

// Send log message 'e' to console and publish to console
// log pubsub system
func (sys *HTTPConsoleLoggerSys) Send(ctx context.Context, entry interface{}) error {
	var lg log.Info
	switch e := entry.(type) {
	case log.Entry:
		lg = log.Info{Entry: e, NodeName: sys.nodeName}
