/// warning | Advertencia

Puedes declarar múltiples parámetros `Form` en una *path operation*, pero no puedes también declarar campos `Body` que esperas recibir como JSON, ya que el request tendrá el body codificado usando `application/x-www-form-urlencoded` en lugar de `application/json`.

Esto no es una limitación de **FastAPI**, es parte del protocolo HTTP.

## Recapitulación

# Dateien im Request

Mit `File` können sie vom Client hochzuladende Dateien definieren.

/// info

Um hochgeladene Dateien zu empfangen, installieren Sie zuerst <a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>.

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

Das, weil hochgeladene Dateien als „Formulardaten“ gesendet werden.

### Decrypt the Request { #decrypt-the-request }

The TLS Termination Proxy would use the encryption agreed to **decrypt the request**, and would transmit the **plain (decrypted) HTTP request** to the process running the application (for example a process with Uvicorn running the FastAPI application).
