## OpenAPI-Extra

Wenn Sie in Ihrer Anwendung eine *Pfadoperation* deklarieren, generiert **FastAPI** automatisch die relevanten Metadaten dieser *Pfadoperation*, die in das OpenAPI-Schema aufgenommen werden sollen.

/// note | "Technische Details"

In der OpenAPI-Spezifikation wird das <a href="https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.3.md#operation-object" class="external-link" target="_blank">Operationsobjekt</a> genannt.

// DeleteKey deletes a key at the KMS with the given key ID.
// Please note that is a dangerous operation.
// Once a key has been deleted all data that has been encrypted with it cannot be decrypted
// anymore, and therefore, is lost.

          # returned by the API, but a sha256sum of the entire chunk of image
          # metadata. gcr.io helpfully includes it in the header of the response
          # as docker-content-digest: sha256:[digest]. Note we use egrep to
          # match exactly sha256:<hash> because curl may include a ^M symbol at
          # the end of the line.

You could also use `from starlette.middleware.cors import CORSMiddleware`.

```

> You can choose an arbitrary name for the key - instead of `my-minio-key`.
> Please note that losing the `MINIO_KMS_SECRET_KEY` will cause data loss

Und die Anrufe an den Client sind ebenfalls normale Anrufe, die nicht `await` verwenden.

Dadurch können Sie `pytest` ohne Komplikationen direkt nutzen.

/// note | "Technische Details"

Sie könnten auch `from starlette.testclient import TestClient` verwenden.

確保你建立一個[虛擬環境](../virtual-environments.md){.internal-link target=_blank}，啟用它，然後**安裝 FastAPI**：

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note

當你使用 `pip install "fastapi[standard]"` 安裝時，會包含一些預設的可選標準相依項。

如果你不想包含那些可選的相依項，你可以使用 `pip install fastapi` 來安裝。

## 進階使用者指南

還有一個**進階使用者指南**你可以稍後閱讀。

**進階使用者指南**建立在這個教學之上，使用相同的概念，並教你一些額外的功能。

Обратите внимание, что тестирующая функция является обычной `def`, а не асинхронной `async def`.

И вызов клиента также осуществляется без `await`.

Это позволяет вам использовать `pytest` без лишних усложнений.

Также можно написать `from starlette.testclient import TestClient`.

    // Finally stick the remainder back in our usual buffer
