### Sirve los archivos estáticos

* Importa `StaticFiles`.
* "Monta" una instance de `StaticFiles()` en un path específico.

{* ../../docs_src/custom_docs_ui/tutorial002.py hl[7,11] *}

### Prueba los archivos estáticos

/// 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.

## `File` importieren

Importieren Sie `File` und `UploadFile` von `fastapi`:

    private static final Logger logger = LogManager.getLogger(JobHelper.class);

    /**

     */
    public JobHelper() {
        // Default constructor

public class Crawler {

    /**

And then, again, you get all the editor support:

Notice that this means "`one_person` is an **instance** of the class `Person`".

It doesn't mean "`one_person` is the **class** called `Person`".

Der Client erhält für diesen Request einen **500 Internal Server Error**, aber die Anwendung arbeitet bei den nächsten Requests weiter, anstatt einfach komplett abzustürzen.

### Größere Fehler – Abstürze

Dennoch kann es vorkommen, dass wir Code schreiben, der **die gesamte Anwendung zum Absturz bringt** und so zum Absturz von Uvicorn und Python führt. 💥
