이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```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"
    }
}
```

다시 한번, **FastAPI**를 사용하여 해당 선언을 함으로써 얻는 것은:

* 중첩 모델도 편집기 지원(자동완성 등)
* 데이터 변환

This would mean that **FastAPI** would expect a body similar to:

```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"
    }
}
```

Again, doing just that declaration, with **FastAPI** you get:

///

```Python hl_lines="16"
{!> ../../docs_src/dependencies/tutorial011.py!}
```

////

E deste modo nós podemos "parametrizar" a nossa dependência, que agora possui `"bar"` dentro dele, como o atributo `checker.fixed_content`.

## Utilize a instância como dependência

### 响应结果

请求为 `http://example.com/items/foo`（`item_id` 为 `「foo」`）时，客户端会接收到 HTTP 状态码 - 200 及如下 JSON 响应结果：

```JSON
{
  "item": "The Foo Wrestlers"
}

```

但如果客户端请求 `http://example.com/items/bar`（`item_id` `「bar」` 不存在时），则会接收到 HTTP 状态码 - 404（「未找到」错误）及如下 JSON 响应结果：

```JSON
{
  "detail": "Item not found"
}

```

/// tip | "提示"

触发 `HTTPException` 时，可以用参数 `detail` 传递任何能转换为 JSON 的值，不仅限于 `str`。

## FAQs

### How does ``MinIO`` manage dependencies?

``MinIO`` uses `go mod` to manage its dependencies.

- Run `go get foo/bar` in the source folder to add the dependency to `go.mod` file.

To remove a dependency

- Edit your code and remove the import reference.
- Run `go mod tidy` in the source folder to remove dependency from `go.mod` file.

    assertThat(url.queryParameterValues("bar")).isEqualTo(listOf(null as String?))
    assertThat(url.queryParameterValues("baz")).isEqualTo(listOf(null as String?))
  }

  @Test
  fun queryParametersWithEmptyValues() {
    val url = parse("http://host/?foo=&bar=&baz=")
    assertThat(url.querySize).isEqualTo(3)
    assertThat(url.queryParameterNames).containsExactlyInAnyOrder("foo", "bar", "baz")

```
{
  "item": "The Foo Wrestlers"
}
```

Mas se o cliente faz uma requisição para `http://example.com/items/bar` (ou seja, um não existente `item_id "bar"`), esse cliente receberá um HTTP status code 404 (o erro "não encontrado" — *not found error*), e uma resposta JSON:

```JSON
{
  "detail": "Item not found"
}
```
