В следующей главе мы рассмотрим реальную защищенную реализацию с хешированием паролей и токенами <abbr title="JSON Web Tokens">JWT</abbr>.

Но пока давайте остановимся на необходимых нам деталях.

Согласно спецификации, вы должны возвращать JSON с `access_token` и `token_type`, как в данном примере.

package main

import (
	"bufio"
	"encoding/json"
	"errors"
	"flag"
	"fmt"
	"log"
	"net/url"
	"os"
	"path/filepath"
	"strings"
	"syscall"

	"github.com/minio/pkg/v3/ellipses"
)

type xl struct {
	This string     `json:"this"`
	Sets [][]string `json:"sets"`
}

type format struct {
	ID string `json:"id"`
	XL xl     `json:"xl"`
}

func getMountMap() (map[string]string, error) {

Por padrão, o **FastAPI** irá converter automaticamente o valor do retorno para JSON utilizando o `jsonable_encoder` explicado em [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Então, por baixo dos panos, ele incluiria esses dados compatíveis com JSON (e.g. um `dict`) dentro de uma `JSONResponse` que é utilizada para enviar uma resposta para o cliente.

예를 들면, 위의 이 모델은 JSON "`object`" (혹은 파이썬 `dict`)을 다음과 같이 선언합니다:

```JSON
{
    "name": "Foo",
    "description": "선택적인 설명란",
    "price": 45.2,
    "tax": 3.5
}
```

...`description`과 `tax`는 (기본 값이 `None`으로 되어 있어) 선택적이기 때문에, 이 JSON "`object`"는 다음과 같은 상황에서도 유효합니다:

```JSON
{
    "name": "Foo",
    "price": 45.2
}
```

## 매개변수로서 선언하기

sleep 5

enabled_minio2=$(./mc stat --json minio2/newbucket-olock | jq -r .ObjectLock.enabled)
if [ $? -ne 0 ]; then
	echo "expected bucket to be mirrored with object-lock but not present, exiting..."
	exit_1
fi

if [ "${enabled_minio2}" != "Enabled" ]; then
	echo "expected bucket to be mirrored with object-lock enabled, exiting..."
	exit_1
fi

**FastAPI** will take the Pydantic model from there, generate the JSON Schema, and put it in the correct place.

The correct place is:

* In the key `content`, that has as value another JSON object (`dict`) that contains:
    * A key with the media type, e.g. `application/json`, that contains as value another JSON object, that contains:
        * A key `schema`, that has as the value the JSON Schema from the model, here's the correct place.

sleep 5

enabled_minio2=$(./mc stat --json minio2/newbucket-olock | jq -r .ObjectLock.enabled)
if [ $? -ne 0 ]; then
	echo "expected bucket to be mirrored with object-lock but not present, exiting..."
	exit_1
fi

if [ "${enabled_minio2}" != "Enabled" ]; then
	echo "expected bucket to be mirrored with object-lock enabled, exiting..."
	exit_1
fi

Anda bisa menghasilkan *anggota enumerasi* dari *operasi path* bahkan di body JSON bersarang (contoh `dict`).

They will be converted to their corresponding values (strings in this case) before returning them to the client:

{* ../../docs_src/path_params/tutorial005.py hl[18,21,23] *}

Klien akan mendapatkan respon JSON seperti berikut:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

	getNetInfoRPC                  = grid.NewSingleHandler[*grid.MSS, *grid.JSON[madmin.NetInfo]](grid.HandlerGetNetInfo, grid.NewMSS, madminNetInfo.NewJSON)
	getOSInfoRPC                   = grid.NewSingleHandler[*grid.MSS, *grid.JSON[madmin.OSInfo]](grid.HandlerGetOSInfo, grid.NewMSS, madminOSInfo.NewJSON)
	getPartitionsRPC               = grid.NewSingleHandler[*grid.MSS, *grid.JSON[madmin.Partitions]](grid.HandlerGetPartitions, grid.NewMSS, madminPartitions.NewJSON)

Isso significa que ele **sempre terá um valor**, só que às vezes o valor pode ser `None` (ou `null` em termos de JSON).
