# 벤치마크

독립적인 TechEmpower 벤치마크에 따르면 **FastAPI** 애플리케이션이 Uvicorn을 사용하여 <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">가장 빠른 Python 프레임워크 중 하나</a>로 실행되며, Starlette와 Uvicorn 자체(내부적으로 FastAPI가 사용하는 도구)보다 조금 아래에 위치합니다.

그러나 벤치마크와 비교를 확인할 때 다음 사항을 염두에 두어야 합니다.

## 벤치마크와 속도

벤치마크를 확인할 때, 일반적으로 여러 가지 유형의 도구가 동등한 것으로 비교되는 것을 볼 수 있습니다.

### Pydantic v1 parameters { #pydantic-v1-parameters }

If you need to use some of the FastAPI-specific tools for parameters like `Body`, `Query`, `Form`, etc. with Pydantic v1 models, you can import them from `fastapi.temp_pydantic_v1_params` while you finish the migration to Pydantic v2:

{* ../../docs_src/pydantic_v1_in_v2/tutorial004_an_py310.py hl[4,18] *}

	return nil
}

func (c *OperatorDNS) endpoint(bucket string, del bool) (string, error) {
	u, err := url.Parse(c.Endpoint)
	if err != nil {
		return "", err
	}
	q := u.Query()
	q.Add("bucket", bucket)
	q.Add("delete", strconv.FormatBool(del))
	u.RawQuery = q.Encode()
	return u.String(), nil
}

// Put - Adds DNS entries into operator webhook server

	}
	w.WriteHeader(http.StatusBadGateway)
}

func (f *Forwarder) getURLFromRequest(req *http.Request) *url.URL {
	// If the Request was created by Go via a real HTTP request,  RequestURI will
	// contain the original query string. If the Request was created in code, RequestURI
	// will be empty, and we will use the URL object instead
	u := req.URL
	if req.RequestURI != "" {
		parsedURL, err := url.ParseRequestURI(req.RequestURI)

But there could be cases where you want to be able to set parameters on the dependency, without having to declare many different functions or classes.

Let's imagine that we want to have a dependency that checks if the query parameter `q` contains some fixed content.

But we want to be able to parameterize that fixed content.

## A "callable" instance { #a-callable-instance }

### `Depends`のインポート

{* ../../docs_src/dependencies/tutorial001.py hl[3] *}

### "dependant"での依存関係の宣言

*path operation関数*のパラメータに`Body`や`Query`などを使用するのと同じように、新しいパラメータに`Depends`を使用することができます:

{* ../../docs_src/dependencies/tutorial001.py hl[13,18] *}

関数のパラメータに`Depends`を使用するのは`Body`や`Query`などと同じですが、`Depends`の動作は少し異なります。

`Depends`は１つのパラメータしか与えられません。

このパラメータは関数のようなものである必要があります。

そして、その関数は、*path operation関数*が行うのと同じ方法でパラメータを取ります。

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[9] *}

/// info | Інформація

`File`  — це клас, який безпосередньо успадковує `Form`.

Але пам’ятайте, що коли Ви імпортуєте `Query`, `Path`, `File` та інші з `fastapi`, це насправді функції, які повертають спеціальні класи.
