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"
{!../../docs_src/middleware/tutorial001.py!}
```

## `python-jose` のインストール

PythonでJWTトークンの生成と検証を行うために、`python-jose`をインストールする必要があります：

<div class="termy">

```console
$ pip install python-jose[cryptography]

---> 100%
```

</div>

また、<a href="https://github.com/mpdavis/python-jose" class="external-link" target="_blank">Python-jose</a>だけではなく、暗号を扱うためのパッケージを追加で必要とします。

## GraphQL with Strawberry

Para esses casos, você pode usar o `jsonable_encoder` para converter seus dados antes de repassá-los para a resposta:

```Python hl_lines="6-7  21-22"
{!../../docs_src/response_directly/tutorial001.py!}
```

/// note | Detalhes Técnicos

Você também pode utilizar `from starlette.responses import JSONResponse`.

这样一来，**FastAPI** 就会调用覆盖依赖项，不再调用原依赖项。

```Python hl_lines="26-27  30"
{!../../docs_src/dependency_testing/tutorial001.py!}
```

/// tip | "提示"

**FastAPI** 应用中的任何位置都可以实现覆盖依赖项。

原依赖项可用于*路径操作函数*、*路径操作装饰器*（不需要返回值时）、`.include_router()` 调用等。

FastAPI 可以覆盖这些位置的依赖项。

///

然后，使用 `app.dependency_overrides` 把覆盖依赖项重置为空**字典**：

```Python
app.dependency_overrides = {}
```

/// tip | "提示"

/// note | "備考"

`status_code`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation関数*のものではありません。

///

`status_code`パラメータはHTTPステータスコードを含む数値を受け取ります。
