# 请求体 - 多个参数

既然我们已经知道了如何使用 `Path` 和 `Query`，下面让我们来了解一下请求体声明的更高级用法。

## 混合使用 `Path`、`Query` 和请求体参数

首先，毫无疑问地，你可以随意地混合使用 `Path`、`Query` 和请求体参数声明，**FastAPI** 会知道该如何处理。

你还可以通过将默认值设置为 `None` 来将请求体参数声明为可选参数：

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note

请注意，在这种情况下，将从请求体获取的 `item` 是可选的。因为它的默认值为 `None`。

///

## 多个请求体参数

在上面的示例中，*路径操作*将期望一个具有 `Item` 的属性的 JSON 请求体，就像：

```JSON

   * href="https://url.spec.whatwg.org/#syntax-url-path-segment">URL path segments</a>. The returned
   * escaper escapes all non-ASCII characters, even though <a
   * href="https://url.spec.whatwg.org/#url-code-points">many of these are accepted in modern
   * URLs</a>. (<a href="https://url.spec.whatwg.org/#path-state">If the escaper were to leave these

        /**
         * Create a new change notification handle
         *
         * @param path directory path
         * @param key lease key
         * @param dir directory file
         */
        public ChangeNotificationHandle(String path, Smb2LeaseKey key, SmbFile dir) {
            this.directoryPath = path;
            this.leaseKey = key;
            this.directoryFile = dir;
            this.active = true;

For that you need to access the request directly.

{* ../../docs_src/using_request_directly/tutorial001_py39.py hl[1,7:8] *}

By declaring a *path operation function* parameter with the type being the `Request` **FastAPI** will know to pass the `Request` in that parameter.

/// tip

Note that in this case, we are declaring a path parameter beside the request parameter.
