## `Header` 임포트

먼저 `Header`를 임포트합니다:

```Python hl_lines="3"
{!../../../docs_src/header_params/tutorial001.py!}
```

## `Header` 매개변수 선언

`Path`, `Query` 그리고 `Cookie`를 사용한 동일한 구조를 이용하여 헤더 매개변수를 선언합니다.

첫 번째 값은 기본값이며, 추가 검증이나 어노테이션 매개변수 모두 전달할 수 있습니다:

```Python hl_lines="9"
{!../../../docs_src/header_params/tutorial001.py!}
```

!!! note "기술 세부사항"

👆 💪 🔬 🎚 🔢 🎏 🌌 👆 🔬 `Query`, `Path` & `Cookie` 🔢.

## 🗄 `Header`

🥇 🗄 `Header`:

=== "🐍 3️⃣.6️⃣ & 🔛"

    ```Python hl_lines="3"
    {!> ../../../docs_src/header_params/tutorial001.py!}
    ```

=== "🐍 3️⃣.1️⃣0️⃣ & 🔛"

    ```Python hl_lines="1"
    {!> ../../../docs_src/header_params/tutorial001_py310.py!}
    ```

## 📣 `Header` 🔢

⤴️ 📣 🎚 🔢 ⚙️ 🎏 📊 ⏮️ `Path`, `Query` & `Cookie`.

ヘッダーのパラメータは、`Query`や`Path`、`Cookie`のパラメータを定義するのと同じように定義できます。

## `Header`をインポート

まず、`Header`をインポートします:

```Python hl_lines="3"
{!../../../docs_src/header_params/tutorial001.py!}
```

## `Header`のパラメータの宣言

次に、`Path`や`Query`、`Cookie`と同じ構造を用いてヘッダーのパラメータを宣言します。

最初の値がデフォルト値で、追加の検証パラメータや注釈パラメータをすべて渡すことができます。

```Python hl_lines="9"
{!../../../docs_src/header_params/tutorial001.py!}
```

!!! note "技術詳細"

  v2_reader_->Seek(kHeaderEntryKey);
  for (v2_reader_->Next(); v2_reader_->Valid(); v2_reader_->Next()) {
    if (filtered_keys.count(string(v2_reader_->key())) > 0) continue;
    CHECK(entry.ParseFromArray(v2_reader_->value().data(),
                               v2_reader_->value().size()))
        << entry.InitializationErrorString();
    string key(v2_reader_->key());

# Header Parameters

You can define Header parameters the same way you define `Query`, `Path` and `Cookie` parameters.

## Import `Header`

First import `Header`:

=== "Python 3.10+"

    ```Python hl_lines="3"
    {!> ../../../docs_src/header_params/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="3"
    {!> ../../../docs_src/header_params/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

## importe `Header`

Primeiro importe `Header`:

=== "Python 3.10+"

    ```Python hl_lines="1"
    {!> ../../../docs_src/header_params/tutorial001_py310.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="3"
    {!> ../../../docs_src/header_params/tutorial001.py!}
    ```

## Declare parâmetros de `Header`

 private:
  // Uses "v2_reader_" to build "var name -> shape" and "var name -> data type"
  // maps; both owned by caller.
  // REQUIRES: "v2_reader_ != nullptr && v2_reader_.status().ok()".
  std::pair<std::unique_ptr<TensorSliceReader::VarToShapeMap>,
            std::unique_ptr<TensorSliceReader::VarToDataTypeMap> >
  BuildV2VarMaps();

  // Invariant: exactly one of "reader_" and "v2_reader_" is non-null.
