Por exemplo, ele não recebe objetos `datetime`, pois estes objetos não são compatíveis com JSON.

Então, um objeto `datetime` teria que ser convertido em um `str` contendo os dados no formato  <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO</a>.

Da mesma forma, este banco de dados não receberia um modelo Pydantic (um objeto com atributos), apenas um `dict`.

Geri kalanı ise **FastAPI** tarafından işlenecektir.

Eğer uygulamanızı çalıştırıp <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a> adresine giderseniz, Flask'tan gelen yanıtı göreceksiniz:

```txt
Hello, World from Flask!
```

///

/// note | "Technical Details"

Any function that is valid to use with:

* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager" class="external-link" target="_blank">`@contextlib.contextmanager`</a> or
* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

///

/// note | "Technische Details"

Jede Funktion, die dekoriert werden kann mit:

* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager" class="external-link" target="_blank">`@contextlib.contextmanager`</a> oder
* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

この行はローカルマシンでアプリが提供されているURLを示しています。

### チェック

ブラウザで<a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>を開きます。

次のようなJSONレスポンスが表示されます:

```JSON
{"message": "Hello World"}
```

### 対話的APIドキュメント

次に、<a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>にアクセスします。

Mithilfe der oben genannten Informationen können Sie dieselbe Hilfsfunktion verwenden, um das OpenAPI-Schema zu generieren und jeden benötigten Teil zu überschreiben.

Fügen wir beispielsweise <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" class="external-link" target="_blank">ReDocs OpenAPI-Erweiterung</a> zum Einbinden eines benutzerdefinierten Logos hinzu.

### Normales **FastAPI**

        Map<String, String> childUrlRuleMap = newHashMap();
        childUrlRuleMap.put("//A", "href");
        childUrlRuleMap.put("//AREA", "href");
        childUrlRuleMap.put("//FRAME", "src");
        childUrlRuleMap.put("//IFRAME", "src");
        childUrlRuleMap.put("//IMG", "src");
        childUrlRuleMap.put("//LINK", "href");
        childUrlRuleMap.put("//SCRIPT", "src");
        htmlTransformer.setChildUrlRuleMap(childUrlRuleMap);

And the rest will be handled by **FastAPI**.

If you run it and go to <a href="http://localhost:8000/v1/" class="external-link" target="_blank">http://localhost:8000/v1/</a> you will see the response from Flask:

```txt
Hello, World from Flask!
```

And if you go to <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> you will see the response from FastAPI:

## 容器镜像

Docker 一直是创建和管理**容器镜像**和**容器**的主要工具之一。

还有一个公共 <a href="https://hub.docker.com/" class="external-link" target="_blank">Docker Hub</a> ，其中包含预制的 **官方容器镜像**, 适用于许多工具、环境、数据库和应用程序。

例如，有一个官方的 <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python 镜像</a>。

还有许多其他镜像用于不同的需要（例如数据库），例如：


* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>

 * closing streams for you.
