### 创建回调的 `APIRouter` { #create-a-callback-apirouter }

首先，新建包含一些用于回调的 `APIRouter`。

### 创建回调*路径操作* { #create-the-callback-path-operation }

创建回调*路径操作*也使用之前创建的 `APIRouter`。

它看起来和常规 FastAPI *路径操作*差不多：

* 声明要接收的请求体，例如，`body: InvoiceEvent`
* 还要声明要返回的响应，例如，`response_model=InvoiceEventReceived`

	isAttach := operation == "attach"

	password := cred.SecretKey

## シンプルな HTTP Basic 認証 { #simple-http-basic-auth }

- `HTTPBasic` と `HTTPBasicCredentials` をインポートします。
- `HTTPBasic` を使って「`security` スキーム」を作成します。
- その `security` を依存関係として path operation に使用します。
- `HTTPBasicCredentials` 型のオブジェクトが返ります:
    - 送信された `username` と `password` を含みます。

_Netflix_, for example, developed two new staging committers - the Directory staging committer and the Partitioned staging committer - to take full advantage of native object storage operations. These committers do not require rename operation. The two staging committers were evaluated, along with another new addition called the Magic committer for benchmarking.

It was found that the directory staging committer was the fastest among the three, S3A connector should be configured with the following...
