/// tip | Tipp

Sie können den Wert `"lenet"` außerdem mittels `ModelName.lenet.value` abrufen.

///

#### *Enum-Member* zurückgeben

Sie können *Enum-Member* in ihrer *Pfadoperation* zurückgeben, sogar verschachtelt in einem JSON-Body (z. B. als `dict`).

      options:
        - label: I'm @tiangolo or he asked me directly to create an issue here.
          required: true
  - type: textarea
    id: content
    attributes:
      label: Issue Content

/// note | Technische Details

Sie können auch `from starlette.websockets import WebSocket` verwenden.

**FastAPI** stellt den gleichen `WebSocket` direkt zur Verfügung, als Annehmlichkeit für Sie, den Entwickler. Er kommt aber direkt von Starlette.

## Nachrichten erwarten und Nachrichten senden

In Ihrer WebSocket-Route können Sie Nachrichten `await`en und Nachrichten senden.

        // Create content with empty lines and comments
        String content = "# Comment line\n" + "\n" + // empty line
                "word1\n" + "  \n" + // whitespace line (may be treated as content)
                "# Another comment\n" + "word2\n";

        // Write content to test file
        writeTestFile(content);

        // Reload and verify

/**
 * Search request body for related content administration API.
 */
public class SearchBody extends BaseSearchBody {

    /**
     * Default constructor.
     */
    public SearchBody() {
        super();
    }

    /** Search term for related content */
    public String term;

    /** Content text for related content */
    public String content;

### Unbegrenzte Erweiterungen

Oder mit anderen Worten, sie werden nicht benötigt. Importieren und nutzen Sie den Code, den Sie brauchen.

We can see that we were redirected because `response.request().url()` is different from `request.url()`. The two log statements log two different URLs.
