```Python
item: Item = Body(embed=True)
```

as in:

{* ../../docs_src/body_multiple_params/tutorial005_an_py310.py hl[17] *}


In this case **FastAPI** will expect a body like:

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,

```Python
item: Item = Body(embed=True)
```

so wie in:

{* ../../docs_src/body_multiple_params/tutorial005_an_py310.py hl[17] *}

In diesem Fall erwartet **FastAPI** einen Body wie:

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,

## 在*路径操作装饰器*中添加 `dependencies` 参数

*路径操作装饰器*支持可选参数 ~ `dependencies`。

该参数的值是由 `Depends()` 组成的 `list`：

{* ../../docs_src/dependencies/tutorial006.py hl[17] *}

路径操作装饰器依赖项（以下简称为**“路径装饰器依赖项”**）的执行或解析方式和普通依赖项一样，但就算这些依赖项会返回值，它们的值也不会传递给*路径操作函数*。

/// tip | 提示

有些编辑器会检查代码中没使用过的函数参数，并显示错误提示。

在*路径操作装饰器*中使用 `dependencies` 参数，可以确保在执行依赖项的同时，避免编辑器显示错误提示。

## Modelos Pydantic para Entrada y Salida { #pydantic-models-for-input-and-output }

Digamos que tienes un modelo Pydantic con valores por defecto, como este:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Modelo para Entrada { #model-for-input }

Si usas este modelo como entrada, como aquí:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

```Python
item: Item = Body(embed=True)
```

como en:

{* ../../docs_src/body_multiple_params/tutorial005_an_py310.py hl[17] *}

En este caso, **FastAPI** esperará un cuerpo como:

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,

## Modelos Pydantic para Entrada e Saída { #pydantic-models-for-input-and-output }

Digamos que você tenha um modelo Pydantic com valores padrão, como este:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:7] hl[7] *}

### Modelo para Entrada { #model-for-input }

Se você usar esse modelo como entrada, como aqui:

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py ln[1:15] hl[14] *}

5.  Our classes are not designed to protect against a malicious caller. You
    should not use them for communication between trusted and untrusted code.

6.  For the mainline flavor, we test the libraries using OpenJDK 8, 11, and 17
    on Linux, with some additional testing on newer JDKs and on Windows. Some
    features, especially in `com.google.common.io`, may not work correctly in

  override fun equals(other: Any?): Boolean =
    other is Address &&
      url == other.url &&
      equalsNonHost(other)

  override fun hashCode(): Int {
    var result = 17
    result = 31 * result + url.hashCode()
    result = 31 * result + dns.hashCode()
    result = 31 * result + proxyAuthenticator.hashCode()
    result = 31 * result + protocols.hashCode()

```Python
item: Item = Body(embed=True)
```

como em:

Neste caso o **FastAPI** esperará um corpo como:

```JSON hl_lines="2"

    "item": {
        "name": "Foo",
        "description": "The pretender",
