这意味着 **FastAPI** 将期望类似于以下内容的请求体：

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

再一次，仅仅进行这样的声明，你将通过 **FastAPI** 获得：

* 对被嵌入的模型也适用的编辑器支持（自动补全等）
* 数据转换
* 数据校验

Якщо Ви взаємодієте з цією операцією шляху, надсилаючи два HTTP-заголовки, наприклад:

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

Відповідь буде така:

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

## Підсумок

Оголошуйте заголовки за допомогою `Header`, використовуючи той самий підхід, що й для `Query`, `Path` та `Cookie`.

    assertThat(mapCache.get("key")).isEqualTo("new value");
  }

  @Test
  public void testRemoveEqualKeyWithDifferentReference() {
    String fooReference1 = new String("foo");
    String fooReference2 = new String("foo");
    assertThat(fooReference1).isNotSameInstanceAs(fooReference2);

    assertThat(mapCache.put(fooReference1, "bar")).isNull();
