**FastAPI** will use that *temporal* response to extract the cookies (also headers and status code), and will put them in the final response that contains the value you returned, filtered by any `response_model`.

You can also declare the `Response` parameter in dependencies, and set cookies (and headers) in them.

## Return a `Response` directly

You can also create cookies when returning a `Response` directly in your code.

      clientReader.processNextFrame()
    }.also { expected ->
      assertThat(expected.message)
        .isEqualTo("Control frames must be final.")
    }
  }

  @Test fun reservedFlag1IsUnsupportedWithNoCompression() {
    data.write("ca00".decodeHex()) // Empty pong, flag 1 set.
    assertFailsWith<ProtocolException> {
      clientReader.processNextFrame()
    }.also { expected ->

      Headers.Builder().add("héader1", "value1")
    }.also { expected ->
      assertThat(expected.message)
        .isEqualTo("Unexpected char 0xe9 at 1 in header name: héader1")
    }
  }

  @Test fun builderRejectsUnicodeInHeaderValue() {
    assertFailsWith<IllegalArgumentException> {
      Headers.Builder().add("header1", "valué1")
    }.also { expected ->
      assertThat(expected.message)

Es wird alle Routen von diesem Router als Teil von dieser inkludieren.

/// note | "Technische Details"

Tatsächlich wird intern eine *Pfadoperation* für jede *Pfadoperation* erstellt, die im `APIRouter` deklariert wurde.

Hinter den Kulissen wird es also tatsächlich so funktionieren, als ob alles dieselbe einzige Anwendung wäre.

///

/// check

```Python hl_lines="7"
{!../../docs_src/path_params/tutorial002.py!}
```

In diesem Fall wird `item_id` als `int` deklariert, also als Ganzzahl.

/// check

Dadurch erhalten Sie Editor-Unterstützung innerhalb Ihrer Funktion, mit Fehlerprüfungen, Codevervollständigung, usw.

## Return a `Response` directly

You can also add headers when you return a `Response` directly.

## Client and SDK Generators - Sponsor

There are also some **company-backed** Client and SDK generators based on OpenAPI (FastAPI), in some cases they can offer you **additional features** on top of high-quality generated SDKs/clients.

// Checks for PutObjectPart arguments validity, also validates if bucket exists.
func checkPutObjectPartArgs(ctx context.Context, bucket, object, uploadID string) error {
	return checkMultipartObjectArgs(ctx, bucket, object, uploadID)
}

// Checks for ListParts arguments validity, also validates if bucket exists.

* Give you the received data in the parameter `item`.
    * As you declared it in the function to be of type `Item`, you will also have all the editor support (completion, etc) for all of the attributes and their types.
* Generate <a href="https://json-schema.org" class="external-link" target="_blank">JSON Schema</a> definitions for your model, you can also use them anywhere else you like if it makes sense for your project.
