Und dann verwenden wir das beim Erstellen der `FastAPI`-App.

Dann könnten Sie OpenAPI (einschließlich der Dokumentationsoberflächen) deaktivieren, indem Sie die Umgebungsvariable `OPENAPI_URL` auf einen leeren String setzen, wie zum Beispiel:

<div class="termy">

```console
$ OPENAPI_URL= uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

### Die automatischen Dokumentationen deaktivieren

Der erste Schritt besteht darin, die automatischen Dokumentationen zu deaktivieren, da diese standardmäßig das Standard-CDN verwenden.

Um diese zu deaktivieren, setzen Sie deren URLs beim Erstellen Ihrer `FastAPI`-App auf `None`:

{* ../../docs_src/custom_docs_ui/tutorial001.py hl[8] *}

### Die benutzerdefinierten Dokumentationen hinzufügen

        public boolean verifySignature(byte[] data, int offset, int length) {
            return true; // Default to successful verification
        }

        public void setRetainPayload(boolean retain) {
            this.retainPayload = retain;
        }

        public byte[] getRawPayload() {
            return rawPayload;
        }

        // Expose headerStart for testing
        public int getHeaderStart() {

**FastAPI** bietet dieselben `starlette.responses` auch via `fastapi.responses` an, als Annehmlichkeit für Sie, den Entwickler. Die meisten verfügbaren Responses kommen aber direkt von Starlette.

Und da die `Response` häufig zum Setzen von Headern und Cookies verwendet wird, stellt **FastAPI** diese auch unter `fastapi.Response` bereit.
