Mas há situações específicas onde é útil utilizar o objeto `Request`.

## Utilize o objeto `Request` diretamente

Vamos imaginar que você deseja obter o endereço de IP/host do cliente dentro da sua *função de operação de rota*.

Para isso você precisa acessar a requisição diretamente.

### Bug or Regression

- EndpointSlice IP validation now matches Endpoints IP validation. ([#101084](https://github.com/kubernetes/kubernetes/pull/101084), [@robscott](https://github.com/robscott)) [SIG Apps and Network]

## Концепции развёртывания

В вышеприведённых примерах серверные программы (например Uvicorn) запускали только **один процесс**, принимающий входящие запросы с любого IP (на это указывал аргумент `0.0.0.0`) на определённый порт (в примерах мы указывали порт `80`).

Это основная идея. Но возможно, вы озаботитесь добавлением дополнительных возможностей, таких как:

import okhttp3.internal.connection.RoutePlanner.ConnectResult
import okhttp3.internal.connection.RoutePlanner.Plan
import okhttp3.internal.okHttpName

/**
 * Speculatively connects to each IP address of a target address, returning as soon as one of them
 * connects successfully. This kicks off new attempts every 250 ms until a connect succeeds.

        // Basic hostname/IP validation

 *    "www.squareup.com".
 *
 *  * **A set of hostnames.** These are in the certificate's subject alternative name (SAN)
 *    extension. A subject alternative name is either a literal hostname (`squareup.com`), a literal
 *    IP address (`74.122.190.80`), or a hostname pattern (`*.api.squareup.com`).
 *
 *  * **A validity interval.** A certificate should not be used before its validity interval starts
 *    or after it ends.
