#### Использование `StreamingResponse` с файлоподобными объектами { #using-streamingresponse-with-file-like-objects }

Если у вас есть <a href="https://docs.python.org/3/glossary.html#term-file-like-object" class="external-link" target="_blank">файлоподобный</a> объект (например, объект, возвращаемый `open()`), вы можете создать функцию-генератор для итерации по этому файлоподобному объекту.

	checksum      etag.ETag
	contentSHA256 []byte

	// Client-provided content checksum
	contentHash   Checksum
	contentHasher hash.Hash
	disableMD5    bool

	// Server side computed checksum. In some cases, like CopyObject, a new checksum
	// needs to be computed and saved on the destination object, but the client
	// does not provide it. Not calculated if client-side contentHash is set.
	ServerSideChecksumType   ChecksumType

They can be as **deep** as you need them to be.

**FastAPI** will take care of solving them.

## First dependency "dependable" { #first-dependency-dependable }

You could create a first dependency ("dependable") like:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

It declares an optional query parameter `q` as a `str`, and then it just returns it.
