    regression that was introduced in OkHttp 3.14.5.

## Was sind „Formulardaten“

HTML-Formulare (`<form></form>`) senden die Daten in einer „speziellen“ Kodierung zum Server, welche sich von JSON unterscheidet.

**FastAPI** stellt sicher, dass diese Daten korrekt ausgelesen werden, statt JSON zu erwarten.

Sie erhalten außerdem automatische Vervollständigung für die zu sendende Payload:

/// tip | Tipp

Z. B. `pip install python-multipart`.

Das, weil **OAuth2** „Formulardaten“ zum Senden von `username` und `password` verwendet.

Führen Sie das Beispiel aus mit:

<div class="termy">

```console
$ uvicorn main:app --reload

    the request already contains an `Accept` header.

 *  Fix: Don't crash with a `NullPointerException` if a server sends a close while we're sending a
    ping. OkHttp had a race condition bug.
