在*路径操作*函数内部直接访问模型对象的所有属性：

{* ../../docs_src/body/tutorial002_py310.py *}

## 请求体 + 路径参数 { #request-body-path-parameters }

可以同时声明路径参数和请求体。

**FastAPI** 能识别与**路径参数**匹配的函数参数应该**从路径中获取**，而声明为 Pydantic 模型的函数参数应该**从请求体中获取**。

{* ../../docs_src/body/tutorial003_py310.py hl[15:16] *}

## 请求体 + 路径 + 查询参数 { #request-body-path-query-parameters }

也可以同时声明**请求体**、**路径**和**查询**参数。

**FastAPI** 会分别识别它们，并从正确的位置获取数据。

### *Pfadoperationen* mit `APIRouter` { #path-operations-with-apirouter }

Und dann verwenden Sie ihn, um Ihre *Pfadoperationen* zu deklarieren.

Verwenden Sie ihn auf die gleiche Weise wie die Klasse `FastAPI`:

Com `Form` você pode declarar as mesmas configurações que com `Body` (e `Query`, `Path`, `Cookie`), incluindo validação, exemplos, um alias (por exemplo, `user-name` em vez de `username`), etc.

/// info | Informação

`Form` é uma classe que herda diretamente de `Body`.

///

/// tip | Dica

Avec `Form`, vous pouvez déclarer les mêmes configurations que pour `Body` (ainsi que `Query`, `Path`, `Cookie`), y compris la validation, des exemples, un alias (p. ex. `user-name` au lieu de `username`), etc.

/// info

`Form` est une classe qui hérite directement de `Body`.

These are **JavaScript** objects, not strings, so you can't pass them from Python code directly.

# GraphQL { #graphql }

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

/// tip

**GraphQL** solves some very specific use cases.

It has **advantages** and **disadvantages** when compared to common **web APIs**.

* You can check all the valid Pydantic data types here: [Pydantic data types](https://docs.pydantic.dev/latest/usage/types/types/).

## Example { #example }

Here's an example *path operation* with parameters using some of the above types.

{* ../../docs_src/extra_data_types/tutorial001_an_py310.py hl[1,3,12:16] *}

Estos son objetos de **JavaScript**, no strings, por lo que no puedes pasarlos directamente desde código de Python.
