これらの場合、リストの型宣言を使用して定義することができます。

重複したヘッダーのすべての値をPythonの`list`として受け取ることができます。

例えば、複数回出現する可能性のある`X-Token`のヘッダを定義するには、以下のように書くことができます:

{* ../../docs_src/header_params/tutorial003.py hl[9] *}

もし、その*path operation*で通信する場合は、次のように２つのHTTPヘッダーを送信します:

```
X-Token: foo
X-Token: bar
```

このレスポンスは以下のようになります:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## まとめ

<img src="/img/tutorial/dependencies/image01.png">

## Einfache Verwendung { #simple-usage }

Näher betrachtet, werden *Pfadoperation-Funktionen* deklariert, um verwendet zu werden, wann immer ein *Pfad* und eine *Operation* übereinstimmen, und dann kümmert sich **FastAPI** darum, die Funktion mit den richtigen Parametern aufzurufen, die Daten aus dem Request extrahierend.

```Python
some_variable: PlaneItem | CarItem
```

하지만 이를 `response_model=PlaneItem | CarItem`과 같이 할당하면 에러가 발생합니다. 이는 Python이 이를 타입 어노테이션으로 해석하지 않고, `PlaneItem`과 `CarItem` 사이의 **잘못된 연산(invalid operation)**을 시도하기 때문입니다

## 모델 리스트

마찬가지로, 객체 리스트 형태의 응답을 선언할 수도 있습니다.

이를 위해 표준 Python의 `typing.List`를 사용하세요(또는 Python 3.9 이상에서는 단순히 `list`를 사용할 수 있습니다):

	// time-duration to keep heal sequence state after it
	// completes.
	keepHealSeqStateDuration = time.Minute * 10

	// nopHeal is a no operating healing action to
	// wait for the current healing operation to finish
	nopHeal = ""
)

var (
	errHealIdleTimeout   = errors.New("healing results were not consumed for too long")
	errHealStopSignalled = errors.New("heal stop signaled")

	"gorm.io/gorm/schema"
)

// for Config.cacheStore store PreparedStmtDB key
const preparedStmtDBKey = "preparedStmt"

// Config GORM config
type Config struct {
	// GORM perform single create, update, delete operations in transactions by default to ensure database data integrity
	// You can disable it by setting `SkipDefaultTransaction` to true
	SkipDefaultTransaction    bool
	DefaultTransactionTimeout time.Duration

This document focuses on showing a working example on how to use Object Lambda with MinIO, you must have [MinIO deployed in your environment](https://docs.min.io/community/minio-object-store/operations/installation.html) before you can start using external lambda functions. You also must install Python version 3.8 or later for the lambda handlers to work.

## Example Lambda handler

Install the necessary dependencies.
```sh

import org.apache.maven.api.annotations.Nonnull;
import org.apache.maven.api.annotations.Nullable;

/**
 * Interface to manage the project state and artifacts during the Maven build lifecycle.
 * This service provides operations to:
 * <ul>
 *   <li>Manage project artifacts (main and attached)</li>
 *   <li>Handle source roots and resources</li>
 *   <li>Access and modify project properties</li>
 *   <li>Manage repository configurations</li>

    private List<MavenProject> projects;

    /**
     * The full set of projects before any potential constraining by --projects. Useful in the case where you want to
     * build a smaller set of projects but perform other operations in the context of your reactor.
     */
    private List<MavenProject> allProjects;

    private MavenProject topLevelProject;

    private ProjectDependencyGraph projectDependencyGraph;

///

そして、さらに多くのパラメータを`Query`に渡すことができます。この場合、文字列に適用される、`max_length`パラメータを指定します。

```Python
q: Union[str, None] = Query(default=None, max_length=50)
```

これにより、データを検証し、データが有効でない場合は明確なエラーを表示し、OpenAPIスキーマの　*path operation* にパラメータを記載します。

## バリデーションをさらに追加する

パラメータ`min_length`も追加することができます:

{* ../../docs_src/query_params_str_validations/tutorial003.py hl[10] *}

## 正規表現の追加
