### 定义子模型

例如，我们可以定义一个 `Image` 模型：

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[7:9] *}

### 将子模型用作类型

然后我们可以将其用作一个属性的类型：

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

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": {

	for za0001 := range...

            (byte) 49, (byte) 41, (byte) 33, (byte) 25, (byte) 17, (byte) 9, (byte) 1, (byte) 58, (byte) 50, (byte) 42, (byte) 34,
            (byte) 26, (byte) 18, (byte) 10, (byte) 2, (byte) 59, (byte) 51, (byte) 43, (byte) 35, (byte) 62, (byte) 54, (byte) 46,
            (byte) 38, (byte) 30, (byte) 22, (byte) 14, (byte) 6, (byte) 61, (byte) 53, (byte) 45, (byte) 37, (byte) 29, (byte) 21,

所有这些依赖都可以使用 `yield`。

在这种情况下，`dependency_c` 在执行其退出代码时需要 `dependency_b`（此处称为 `dep_b`）的值仍然可用。

而 `dependency_b` 反过来则需要 `dependency_a`（此处称为 `dep_a` ）的值在其退出代码中可用。

{* ../../docs_src/dependencies/tutorial008_an_py39.py hl[18:19,26:27] *}

同样，你可以混合使用带有 `yield` 或 `return` 的依赖。

你也可以声明一个依赖于多个带有 `yield` 的依赖，等等。

你可以拥有任何你想要的依赖组合。

**FastAPI** 将确保按正确的顺序运行所有内容。

Guava comes in two flavors:

*   The JRE flavor requires JDK 1.8 or higher.
*   If you need support for Android, use
    [the Android flavor](https://github.com/google/guava/wiki/Android). You can
    find the Android Guava source in the [`android` directory].
