## Media types adicionais para o retorno principal

Você pode utilizar o mesmo parâmetro `responses` para adicionar diferentes media types para o mesmo retorno principal.

Por exemplo, você pode adicionar um media type adicional de `image/png`, declarando que a sua *operação de caminho* pode retornar um objeto JSON (com o media type `application/json`) ou uma imagem PNG:

Houveram mudanças no próprio Pydantic para que isso fosse possível.

As capturas de tela anteriores foram capturas no <a href="https://code.visualstudio.com" class="external-link" target="_blank">Visual Studio Code</a>.

Mas você terá o mesmo suporte do editor no <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a> e na maioria dos editores Python:

│   ├── main.py
│   └── test_main.py
```

Digamos que agora o arquivo `main.py` com seu aplicativo **FastAPI** tenha algumas outras **operações de rotas**.

Ele tem uma operação `GET` que pode retornar um erro.

Ele tem uma operação `POST` que pode retornar vários erros.

Ambas as *operações de rotas* requerem um cabeçalho `X-Token`.

To host multiple tenants in a distributed environment, run several distributed MinIO Server instances concurrently.

### 2.1 Host Multiple Tenants on Multiple Drives (Erasure Code)

Use the following commands to host 3 tenants on a 4-node distributed configuration:

```sh
export MINIO_ROOT_USER=<TENANT1_ACCESS_KEY>
export MINIO_ROOT_PASSWORD=<TENANT1_SECRET_KEY>

		apiRouter.ServeHTTP(recV4, reqV4)
		// Assert the response code with the expected status.
		if recV4.Code != testCase.expectedRespStatus {
			t.Fatalf("Case %d: Expected the response status to be `%d`, but instead found `%d`", i+1, testCase.expectedRespStatus, recV4.Code)
		}
		// read the response body.
		bucketPolicyReadBuf, err := io.ReadAll(recV4.Body)
		if err != nil {

//   example, one cannot use the output of "switch" node as input.
// - `inputs` and `outputs` cannot have reference types. Reference types are

// - Every node in the function's body must have all of its inputs (including
