## 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)

errors.no_user_for_changing_password=The current password is not correct.
errors.failed_to_change_password=Failed to change your password.

errors.failed_to_reindex=Failed to start re-indexing from {0} to {1}.

// If none of the http routes match respond with appropriate errors
func errorResponseHandler(w http.ResponseWriter, r *http.Request) {
	if r.Method == http.MethodOptions {

	}
	desc := "Do not upgrade one server at a time - please follow the recommended guidelines mentioned here https://github.com/minio/minio#upgrading-minio for your environment"
	switch {
	case strings.HasPrefix(r.URL.Path, peerRESTPrefix):

## Example upgrade

Now modify the file `main.py` to receive a body from a `PUT` request.

Declare the body using standard Python types, thanks to Pydantic.

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

## 範例升級 { #example-upgrade }

現在修改 `main.py` 檔案，使其能從 `PUT` 請求接收 body。

多虧了 Pydantic，你可以用標準的 Python 型別來宣告 body。

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

app = FastAPI()

<div class="termy">

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

---> 100%
```

</div>

/// tip | Порада

Іноді ви можете отримати помилку **`No module named pip`** при спробі оновити pip.

Якщо це сталося, встановіть і оновіть pip за допомогою команди нижче:

<div class="termy">

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

---> 100%
```

</div>

        * Then upgrade nodes to Kubernetes v1.3.
            * As nodes are upgraded, they will automatically, by default, opt-in to attach/detach controller management, which will cause the controller to start managing attaches/detaches for volumes that get scheduled to those nodes.
