!!! note "技術詳細"
    以下と一緒に使用できる関数なら何でも有効です:

frontend-app@1.0.0 generate-client /home/user/code/frontend-app
> openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios
```

</div>

此命令将在 `./src/client` 中生成代码，并将在其内部使用 `axios`（前端HTTP库）。

### 尝试客户端代码

现在您可以导入并使用客户端代码，它可能看起来像这样，请注意，您可以为这些方法使用自动补全：

您还将自动补全要发送的数据：

```Python hl_lines="2  7  9"
{!../../../docs_src/custom_response/tutorial006c.py!}
```

### `StreamingResponse`

Nimmt einen asynchronen Generator oder einen normalen Generator/Iterator und streamt den Responsebody.

```Python hl_lines="2  14"
{!../../../docs_src/custom_response/tutorial007.py!}
```

#### Verwendung von `StreamingResponse` mit dateiähnlichen Objekten

İsterseniz Couchbase tabanlı generator'ı kullanmakta özgürsünüz, hala iyi çalışıyor olmalı ve onunla oluşturulmuş bir projeniz varsa bu da sorun değil (ve muhtemelen zaten ihtiyaçlarınıza göre güncellediniz).

And these same full-stack generators were the base of the [**FastAPI** Project Generators](project-generation.md){.internal-link target=_blank}.

    Flask-apispec was created by the same Marshmallow developers.

    Generate the OpenAPI schema automatically, from the same code that defines serialization and validation.

frontend-app@1.0.0 generate-client /home/user/code/frontend-app
> openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios
```

</div>

You can add code to be run with the `request`,  before any *path operation* receives it.

And also after the `response` is generated, before returning it.

For example, you could add a custom header `X-Process-Time` containing the time in seconds that it took to process the request and generate a response:

```Python hl_lines="10  12-13"
