Nesse caso, o path original `/app` seria servido em `/api/v1/app`.

Embora todo o seu código esteja escrito assumindo que existe apenas `/app`.

## `TrustedHostMiddleware` { #trustedhostmiddleware }

Enforces that all incoming requests have a correctly set `Host` header, in order to guard against HTTP Host Header attacks.

{* ../../docs_src/advanced_middleware/tutorial002_py39.py hl[2,6:8] *}

The following arguments are supported:

## Создать TypeScript SDK { #create-a-typescript-sdk }

Начнём с простого приложения FastAPI:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

Начнем с примера, а затем разберём его подробнее.

Мы создаём асинхронную функцию `lifespan()` с `yield` примерно так:

{* ../../docs_src/events/tutorial003_py39.py hl[16,19] *}

Beginnen wir mit einem Beispiel und sehen es uns dann im Detail an.

Wir erstellen eine asynchrone Funktion `lifespan()` mit `yield` wie folgt:

{* ../../docs_src/events/tutorial003_py39.py hl[16,19] *}

## Ein TypeScript-SDK erstellen { #create-a-typescript-sdk }

Beginnen wir mit einer einfachen FastAPI-Anwendung:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

## Crie um SDK em TypeScript { #create-a-typescript-sdk }

Vamos começar com uma aplicação FastAPI simples:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

Note que as *operações de rota* definem os modelos que usam para o corpo da requisição e o corpo da resposta, usando os modelos `Item` e `ResponseMessage`.

### Documentação da API { #api-docs }

{* ../../docs_src/advanced_middleware/tutorial001_py39.py hl[2,6] *}

## `TrustedHostMiddleware` { #trustedhostmiddleware }

Erzwingt, dass alle eingehenden Requests einen korrekt gesetzten `Host`-Header haben, um sich vor HTTP-Host-Header-Angriffen zu schützen.

{* ../../docs_src/advanced_middleware/tutorial002_py39.py hl[2,6:8] *}

Die folgenden Argumente werden unterstützt:

## Crea un SDK de TypeScript { #create-a-typescript-sdk }

Empecemos con una aplicación simple de FastAPI:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

Nota que las *path operations* definen los modelos que usan para el payload del request y el payload del response, usando los modelos `Item` y `ResponseMessage`.
