### Déployer votre application (optionnel) { #deploy-your-app-optional }

Vous pouvez, si vous le souhaitez, déployer votre application FastAPI sur [FastAPI Cloud](https://fastapicloud.com), allez vous inscrire sur la liste d'attente si ce n'est pas déjà fait. 🚀

					// This will give an estimate of the total ops/s.
					latency := float64(atomic.LoadInt64(&lat)) / float64(time.Millisecond)
					b.ReportMetric(float64(n)*float64(ops)/spent.Seconds(), "vops/s")
					b.ReportMetric(latency/float64(ops), "ms/op")
				}
			})
		}
	})
	b.Run("rpc", func(b *testing.B) {
		for par := 1; par <= 32; par *= 2 {

Estos ataques aprovechan que los navegadores permiten que los scripts envíen requests sin hacer un preflight de CORS cuando:

* no tienen un header `Content-Type` (p. ej. usando `fetch()` con un body `Blob`)
* y no envían credenciales de autenticación.

Este tipo de ataque es relevante principalmente cuando:

vars:
  - pr-job: "part-2"

---
jjbb-template: periodic-trigger-lgc.yml
vars:

  - lgc-job: elastic+elasticsearch+%BRANCH%+intake

# 고급 Middleware { #advanced-middleware }

메인 튜토리얼에서 애플리케이션에 [커스텀 Middleware](../tutorial/middleware.md)를 추가하는 방법을 읽었습니다.

그리고 [`CORSMiddleware`로 CORS 처리하기](../tutorial/cors.md)도 읽었습니다.

이 섹션에서는 다른 middleware들을 사용하는 방법을 살펴보겠습니다.

## ASGI middleware 추가하기 { #adding-asgi-middlewares }

**FastAPI**는 Starlette를 기반으로 하고 <abbr title="Asynchronous Server Gateway Interface - 비동기 서버 게이트웨이 인터페이스">ASGI</abbr> 사양을 구현하므로, 어떤 ASGI middleware든 사용할 수 있습니다.

# Middleware Avançado { #advanced-middleware }

No tutorial principal você leu como adicionar [Middleware Personalizado](../tutorial/middleware.md) à sua aplicação.

E então você também leu como lidar com [CORS com o `CORSMiddleware`](../tutorial/cors.md).

Nesta seção, veremos como usar outros middlewares.

## Adicionando middlewares ASGI { #adding-asgi-middlewares }

	writer.WriteByte('`')

func (DummyDialector) Explain(sql string, vars ...interface{}) string {
	return logger.ExplainSQL(sql, nil, `"`, vars...)
}

func (DummyDialector) DataTypeOf(*schema.Field) string {
	return ""
}

func (d DummyDialector) Translate(err error) error {
	return d.TranslatedErr

Environment variables could be useful for handling application **settings**, as part of the **installation** of Python, etc.

## Create and Use Env Vars { #create-and-use-env-vars }

You can **create** and use environment variables in the **shell (terminal)**, without needing Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
