This code is something you can actually use in your application, save the password hashes in your database, etc.

We are going to start from where we left in the previous chapter and increment it.

## About JWT { #about-jwt }

JWT means "JSON Web Tokens".

	DB.Preload("Team").Preload("Languages").Preload("Friends").First(&user, "name = ?", user.Name)

	if r, err := json.Marshal(&user); err != nil {
		t.Errorf("failed to marshal users, got error %v", err)
	} else if !regexp.MustCompile(`"Team":\[\],"Languages":\[\],"Friends":\[\]`).MatchString(string(r)) {
		t.Errorf("json marshal is not empty slice, got %v", string(r))
	}

	var results []User

    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["cookie", "santa_tracker"],

`swagger_ui_parameters` recebe um dicionário com as configurações passadas diretamente para o Swagger UI.

O FastAPI converte as configurações para **JSON** para torná-las compatíveis com JavaScript, pois é disso que o Swagger UI precisa.

## Desabilitar destaque de sintaxe { #disable-syntax-highlighting }

Por exemplo, você pode desabilitar o destaque de sintaxe na UI do Swagger.

Wenn Sie gerade erst mit **FastAPI** beginnen, möchten Sie diesen Abschnitt vielleicht überspringen.

## Anwendungsfälle { #use-cases }

Einige Anwendungsfälle sind:

* Konvertieren von Nicht-JSON-Requestbodys nach JSON (z. B. <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Dekomprimierung gzip-komprimierter Requestbodys.
* Automatisches Loggen aller Requestbodys.

Se você abrir no seu navegador a URL:

```
http://127.0.0.1:8000/items/foo-item
```

... sem adicionar o parâmetro obrigatório `needy`, você verá um erro como:

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

Sie können den `jsonable_encoder` verwenden, um die empfangenen Daten in etwas zu konvertieren, das als JSON gespeichert werden kann (z. B. in einer NoSQL-Datenbank). Zum Beispiel, um ein `datetime` in einen `str` zu konvertieren.

Si vous ouvrez une URL comme :

```
http://127.0.0.1:8000/items/foo-item
```

...sans ajouter le paramètre requis `needy`, vous aurez une erreur :

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",
            "type": "value_error.missing"
