```

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

ヘッダーは`Header`で宣言し、`Query`や`Path`、`Cookie`と同じパターンを使用する。

///

#### 기본값이 있는 필드를 갖는 값의 데이터

하지만 모델의 필드가 기본값이 있어도 ID가 `bar`인 항목(items)처럼 데이터가 값을 갖는다면:

```Python hl_lines="3  5"
{
    "name": "Bar",
    "description": "The bartenders",
    "price": 62,
    "tax": 20.2
}
```

응답에 해당 값들이 포함됩니다.

#### 기본값과 동일한 값을 갖는 데이터

            @Override
            public void startElement(final String uri, final String localName, final String qName, final Attributes attributes)
                    throws SAXException {
                if ("bar".equals(qName)) {
                    included = true;
                }
            }

            @Override

    // Plus for spaces
    assertEscaping(e, "+", ' ');
    assertEscaping(e, "%2B", '+');

    assertEquals("safe+with+spaces", e.escape("safe with spaces"));
    assertEquals("foo%40bar.com", e.escape("foo@bar.com"));
  }

  public void testUrlPathSegmentEscaper() {
    UnicodeEscaper e = (UnicodeEscaper) urlPathSegmentEscaper();
    assertPathEscaper(e);
    assertUnescaped(e, '+');
  }

Затем, получив такой URL:

```
http://localhost:8000/items/?q=foo&q=bar
```

вы бы получили несколько значений (`foo` и `bar`), которые относятся к параметру `q`, в виде Python `list` внутри вашей *функции обработки пути*, в *параметре функции* `q`.

Таким образом, ответ на этот URL будет:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```
