これはオプショナルのクエリパラメータ`q`を`str`として宣言し、それを返すだけです。

これは非常にシンプルです（あまり便利ではありません）が、サブ依存関係がどのように機能するかに焦点を当てるのに役立ちます。

## 第二の依存関係 「依存可能なもの」と「依存」 { #second-dependency-dependable-and-dependant }

そして、別の依存関数（「依存可能なもの」）を作成して、同時にそれ自身の依存関係を宣言することができます（つまりそれ自身も「依存」です）:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[13] *}

宣言されたパラメータに注目してみましょう:

	// Generate presigned GET url with lambda function
	presignedURL, err := s3Client.PresignedGetObject(context.Background(), "functionbucket", "testobject", time.Duration(1000)*time.Second, reqParams)
	if err != nil {
		log.Fatalln(err)
	}
	fmt.Println(presignedURL)
}
```

Use the Presigned URL via `curl` to receive the transformed object.
```
curl -v $(go run presigned.go)

                    /*input_shapes*/ {make_shape({3, 2}), make_shape({2, 4})},
                    /*input_tensors*/ {},
                    /*expected_shape*/ make_shape({3, 4}));

  // Infer shape when second operand has unknown shape.
  CheckOutputShapes(matmul_op,
                    /*input_shapes*/ {make_shape({3, 2}), unknown_shape()},
                    /*input_tensors*/ {},

This can be quite noticeable when using `docker compose`. See this Docker Compose FAQ section for more technical details: [Why do my services take 10 seconds to recreate or stop?](https://docs.docker.com/compose/faq/#why-do-my-services-take-10-seconds-to-recreate-or-stop).
