`Body` 同样具有与 `Query`、`Path` 以及其他后面将看到的类完全相同的额外校验和元数据参数。

## 嵌入单个请求体参数

假设你只有一个来自 Pydantic 模型 `Item` 的请求体参数 `item`。

默认情况下，**FastAPI** 将直接期望这样的请求体。

但是，如果你希望它期望一个拥有 `item` 键并在值中包含模型内容的 JSON，就像在声明额外的请求体参数时所做的那样，则可以使用一个特殊的 `Body` 参数 `embed`：

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

比如：

//// tab | Python 3.10+

```Python hl_lines="17"
