And you can use and implement secure, standard protocols, like OAuth2 in a relatively simple way.

Diesen Code können Sie tatsächlich in Ihrer Anwendung verwenden, die Passwort-Hashes in Ihrer Datenbank speichern, usw.

Wir bauen auf dem vorherigen Kapitel auf.

## Über JWT

JWT bedeutet „JSON Web Tokens“.

Es ist ein Standard, um ein JSON-Objekt in einem langen, kompakten String ohne Leerzeichen zu kodieren. Das sieht so aus:

```

/// note | Technical Details

ASGI is a new "standard" being developed by Django core team members. It is still not a "Python standard" (a PEP), although they are in the process of doing that.

Vous faites cela avec les types Python standard modernes.

Vous n'avez pas à apprendre une nouvelle syntaxe, les méthodes ou les classes d'une bibliothèque spécifique, etc.

Juste du **Python** standard.

Par exemple, pour un `int`:

```Python
item_id: int
```

ou pour un modèle `Item` plus complexe :

    </magic>
    <glob pattern="*.gz" />
    <glob pattern="*.tgz" />
    <glob pattern="*-gz" />
  </mime-type>
  <mime-type type="application/zstd">
    <_comment>https://en.wikipedia.org/wiki/Zstandard</_comment>
    <_comment>https://tools.ietf.org/id/draft-kucherawy-dispatch-zstd-01.html</_comment>
    <magic priority="50">
      <match value="0xFD2FB528" type="little32" offset="0"/>
    </magic>

      },
      "reading_term_analyzer_pa" : {
        "type" : "custom",
        "tokenizer" : "standard"
      },
      "normalize_analyzer_pa" : {
        "type" : "custom",
        "tokenizer" : "keyword",
        "char_filter" : ["mapping_char"],
        "filter" : ["lowercase"]
      },
      "contents_analyzer_pa" : {
        "type" : "custom",
        "tokenizer" : "standard",

      },
      "reading_term_analyzer_pa" : {
        "type" : "custom",
        "tokenizer" : "standard"
      },
      "normalize_analyzer_pa" : {
        "type" : "custom",
        "tokenizer" : "keyword",
        "char_filter" : ["mapping_char"],
        "filter" : ["lowercase"]
      },
      "contents_analyzer_pa" : {
        "type" : "custom",
        "tokenizer" : "standard",

Sie schreiben Standard-Python mit Typen:

```Python
from typing import List, Dict
from datetime import date

from pydantic import BaseModel

# Deklarieren Sie eine Variable als ein `str`

///

/// info

OpenAPI 3.1.0 (used since FastAPI 0.99.0) added support for `examples`, which is part of the **JSON Schema** standard.

Before that, it only supported the keyword `example` with a single example. That is still supported by OpenAPI 3.1.0, but is deprecated and is not part of the JSON Schema standard. So you are encouraged to migrate `example` to `examples`. 🤓
