OpenAPI defines the following security schemes:

* `apiKey`: an application specific key that can come from:
    * A query parameter.
    * A header.
    * A cookie.
* `http`: standard HTTP authentication systems, including:
    * `bearer`: a header `Authorization` with a value of `Bearer ` plus a token. This is inherited from OAuth2.

# Body - 多個參數 { #body-multiple-parameters }

現在我們已經知道如何使用 `Path` 與 `Query`，接下來看看更進階的請求主體（request body）宣告用法。

## 混用 `Path`、`Query` 與 Body 參數 { #mix-path-query-and-body-parameters }

首先，當然你可以自由混用 `Path`、`Query` 與請求 Body 參數的宣告，**FastAPI** 會知道該怎麼做。

你也可以將 Body 參數宣告為可選，方法是將預設值設為 `None`：

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

/// note | 注意

請注意，在此情況下，從 body 取得的 `item` 是可選的，因為它的預設值是 `None`。

    @DisplayName("Argument parsing")
    class ArgumentParsing {

        @Test
        @DisplayName("URL parameter is correctly parsed")
        void urlParameterParsing() {
            String expectedUrl = "smb://server/share/test.txt";
            TestLocking t = new TestLocking();

            // Simulate argument parsing

### Remotely Inspecting backend data

# 본문 - 다중 매개변수 { #body-multiple-parameters }

이제 `Path`와 `Query`를 어떻게 사용하는지 확인했으니, 요청 본문 선언에 대한 더 고급 사용법을 살펴보겠습니다.

## `Path`, `Query` 및 본문 매개변수 혼합 { #mix-path-query-and-body-parameters }

먼저, 물론 `Path`, `Query` 및 요청 본문 매개변수 선언을 자유롭게 혼합해서 사용할 수 있고, **FastAPI**는 어떤 동작을 할지 압니다.

또한 기본 값을 `None`으로 설정해 본문 매개변수를 선택사항으로 선언할 수 있습니다:

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