And that function `get_openapi()` receives as parameters:

* `title`: The OpenAPI title, shown in the docs.
* `version`: The version of your API, e.g. `2.5.0`.
* `openapi_version`: The version of the OpenAPI specification used. By default, the latest: `3.1.0`.
* `summary`: A short summary of the API.
* `description`: The description of your API, this can include markdown and will be shown in the docs.

レスポンスに正確に何を含められるかは、OpenAPI 仕様の次のセクションを参照してください:

- [OpenAPI の Responses Object](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responses-object)、ここには `Response Object` が含まれます。

## OpenAPI Extra { #openapi-extra }

当你在应用中声明一个 *路径操作* 时，**FastAPI** 会自动生成与该 *路径操作* 相关的元数据，以包含到 OpenAPI 方案中。

/// note | 技术细节

在 OpenAPI 规范中，这被称为 [Operation 对象](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#operation-object)。

///

它包含关于该 *路径操作* 的所有信息，并用于生成自动文档。

它包括 `tags`、`parameters`、`requestBody`、`responses` 等。

这个特定于 *路径操作* 的 OpenAPI 方案通常由 **FastAPI** 自动生成，但你也可以扩展它。

  /**
   * Returns the absolute uri of the Class-Path entry value as specified in <a
   * href="https://docs.oracle.com/en/java/javase/25/docs/specs/jar/jar.html#main-attributes">JAR
   * File Specification</a>. Even though the specification only talks about relative urls, absolute
   * urls are actually supported too (for example, in Maven surefire plugin).
   */
  @VisibleForTesting

/// warning

Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.
As these keys may not necessarily be part of the OpenAPI specification, some OpenAPI tools, for example [the OpenAPI validator](https://validator.swagger.io/), may not work with your generated schema.

## Recap { #recap }

## Adding ASGI middlewares { #adding-asgi-middlewares }

As **FastAPI** is based on Starlette and implements the <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> specification, you can use any ASGI middleware.

A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.

* 不需要任何實際程式碼，因為你的應用永遠不會呼叫這段程式。它只用來文件化「外部 API」。因此函式可以只有 `pass`。
* 「路徑」可以包含一個 [OpenAPI 3 表達式](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)（見下文），可使用參數與原始送到「你的 API」的請求中的部分欄位。

### 回呼路徑表達式 { #the-callback-path-expression }

回呼的「路徑」可以包含一個 [OpenAPI 3 表達式](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)，能引用原本送到「你的 API」的請求中的部分內容。

在這個例子中，它是一個 `str`：
