Сначала быстро посмотрим, что изменилось по сравнению с примерами из основного раздела **Учебник - Руководство пользователя** — [OAuth2 с паролем (и хешированием), Bearer с JWT-токенами](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Теперь — с использованием OAuth2 scopes:

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:126,130:136,141,157] *}

Теперь рассмотрим эти изменения шаг за шагом.

package cmd

import (
	"context"
	"errors"
	"fmt"
	"io"
	"os"
	pathutil "path"
	"strings"
	"sync"
	"time"

	"github.com/minio/minio/internal/grid"
	xioutil "github.com/minio/minio/internal/ioutil"
)

func renameAllBucketMetacache(epPath string) error {
	// Rename all previous `.minio.sys/buckets/<bucketname>/.metacache` to
	// to `.minio.sys/tmp/` for deletion.

也可以使用 `from starlette import status`。

为了让开发者更方便，**FastAPI** 提供了与 `starlette.status` 完全相同的 `fastapi.status`。但它直接来自于 Starlette。

在大多数情况下，你会（且应该）有一个“终止代理”在上层为你处理 HTTPS，这取决于你如何部署应用程序，你的服务提供商可能会为你处理此事，或者你可能需要自己设置。

Ele também inclui o que mudou, como as validações agora são mais corretas e rigorosas, possíveis ressalvas, etc.

Um `EmailStr` zu verwenden, installieren Sie zuerst <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, sie aktivieren und es dann installieren, zum Beispiel:

```console
$ pip install email-validator
```

oder mit:

// along with this program.  If not, see <http://www.gnu.org/licenses/>.

const (
	dataUsageRoot   = SlashSeparator
	dataUsageBucket = minioMetaBucket + SlashSeparator + bucketMetaPrefix

	dataUsageObjName       = ".usage.json"

- Ellipses and bracket notation (e.g. `{1...10}`) are allowed.

> NOTE: MinIO environmental variables still take precedence over the `config.yaml` file, however `config.yaml` is preferred over MinIO internal config KV settings via `mc admin config set alias/ <sub-system>`.

### TODO

In subsequent releases we are planning to extend this to provide things like
