## Mettre à niveau l'exemple { #example-upgrade }

Modifiez maintenant le fichier `main.py` pour recevoir un corps depuis une requête `PUT`.

Déclarez le corps en utilisant les types Python standard, grâce à Pydantic.

```Python hl_lines="2  7-10 23-25"

     */
    MODULES(StandardLocation.MODULE_PATH, "--module-path"),

    /**
     * The path identified by the Java {@code --upgrade-module-path} option.
     * The Java tools location is {@link StandardLocation#UPGRADE_MODULE_PATH}.
     */
    UPGRADE_MODULES(StandardLocation.UPGRADE_MODULE_PATH, "--upgrade-module-path"),

    /**

## Пример обновления { #example-upgrade }

Теперь измените файл `main.py`, чтобы принимать тело запроса из `PUT` HTTP-запроса.

Объявите тело запроса, используя стандартные типы Python, спасибо Pydantic.

```Python hl_lines="2  7-10 23-25"

  labels:
    app: {{ template "minio.name" . }}-post-job
    chart: {{ template "minio.chart" . }}
    release: {{ .Release.Name }}
    heritage: {{ .Release.Service }}
  annotations:
    "helm.sh/hook": post-install,post-upgrade
    "helm.sh/hook-delete-policy": hook-succeeded,before-hook-creation
    {{- with .Values.postJob.annotations }}
      {{- toYaml . | nindent 4 }}
    {{- end }}
spec:
  template:
    metadata:
      labels:

```console
$ python -m pip install --upgrade pip

---> 100%
```

</div>

/// tip | Tipp

Manchmal kann beim Versuch, `pip` zu aktualisieren, der Fehler **`No module named pip`** auftreten.

Wenn das passiert, installieren und aktualisieren Sie `pip` mit dem folgenden Befehl:

<div class="termy">

```console
$ python -m ensurepip --upgrade

---> 100%
```

</div>

```console
$ python -m pip install --upgrade pip

---> 100%
```

</div>

/// tip | Astuce

Parfois, vous pourriez obtenir une erreur **`No module named pip`** en essayant de mettre à niveau pip.

Si cela arrive, installez et mettez à niveau pip avec la commande ci-dessous :

<div class="termy">

```console
$ python -m ensurepip --upgrade

---> 100%
```

</div>

## 示例升级 { #example-upgrade }

现在修改 `main.py` 文件来接收来自 `PUT` 请求的请求体。

借助 Pydantic，使用标准的 Python 类型来声明请求体。

```Python hl_lines="2  7-10 23-25"
from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

Nicht abwärtskompatible Änderungen und neue Funktionen werden in „MINOR“-Versionen hinzugefügt.

/// tip | Tipp

„MINOR“ ist die Zahl in der Mitte, zum Beispiel ist in `0.2.3` die MINOR-Version `2`.

///

## Upgrade der FastAPI-Versionen { #upgrading-the-fastapi-versions }

Sie sollten Tests für Ihre App hinzufügen.

Mit **FastAPI** ist das sehr einfach (dank Starlette), schauen Sie sich die Dokumentation an: [Testen](../tutorial/testing.md)
