This could be especially useful during testing, as it's very easy to override a dependency with your own custom settings.

### The config file { #the-config-file }

Coming from the previous example, your `config.py` file could look like:

{* ../../docs_src/settings/app02/config.py hl[10] *}

Notice that now we don't create a default instance `settings = Settings()`.

### The main app file { #the-main-app-file }

//	    modify the user-agent.
//
//	Authorization:
//
//	    Is skipped for obvious reasons
var ignoredHeaders = map[string]bool{
	"Authorization": true,
	"User-Agent":    true,
}

// Headers to ignore in streaming v4
var ignoredStreamingHeaders = map[string]bool{
	"Authorization": true,
	"Content-Type":  true,
	"Content-Md5":   true,
	"User-Agent":    true,
}

    @Override
    protected void setupHtmlData(final ActionRuntime runtime) {
        super.setupHtmlData(runtime);

            }
            return null;
        }

## Pydantic

すべてのデータバリデーションは <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> によって内部で実行されるため、Pydanticの全てのメリットが得られます。そして、安心して利用することができます。

`str`、 `float` 、 `bool` および他の多くの複雑なデータ型を型宣言に使用できます。

これらのいくつかについては、チュートリアルの次の章で説明します。

## 順序の問題

`/users/me` から、現在のユーザに関するデータを取得するとします。

FastAPI позволяет использовать **аннотации типов** таким же способом, как и для ввода данных в  **параметры** функции, вы можете использовать модели Pydantic, списки, словари, скалярные типы (такие, как int, bool и т.д.).

{* ../../docs_src/response_model/tutorial001_01_py310.py hl[16,21] *}

FastAPI будет использовать этот возвращаемый тип для:

* **Валидации** ответа.

The job should produce an output as shown below. Note the value of pi in the output.

```
17/03/22 23:21:10 INFO DAGScheduler: Job 0 finished: reduce at SparkPi.scala:38, took 1.302805 s
Pi is roughly 3.1445191445191445
```

Job status can also be viewed in a browser by navigating to the YARN ResourceManager Web UI and clicking on job history server information.
