通过仅使用 `BackgroundTasks` (而不是 `BackgroundTask`)，使得能将它作为 *路径操作函数* 的参数 ，并让**FastAPI**为您处理其余部分, 就像直接使用 `Request` 对象。

在FastAPI中仍然可以单独使用 `BackgroundTask`，但您必须在代码中创建对象，并返回包含它的Starlette `Response`。

### Using WebIdentiy API

On another terminal run `web-identity.go` a sample client application which obtains JWT id_tokens from an identity provider, in our case its Keycloak. Uses the returned id_token response to get new temporary credentials from the MinIO server using the STS API call `AssumeRoleWithWebIdentity`.

```

    * including a Target Information block in the message.  The Target
    * Information block is used in the calculation of the NTLMv2 response.
