### DNS

Теперь давайте сфокусируемся на работе с HTTPS.

Всё начинается с того, что браузер спрашивает у **DNS-серверов**, какой **IP-адрес связан с доменом**, для примера возьмём домен `someapp.example.com`.

DNS-сервера присылают браузеру определённый **IP-адрес**, тот самый публичный IP-адрес вашего сервера, который вы указали в ресурсной "записи А" при настройке.

$ echo "Hello $Env:MY_NAME"

Hello Wade Wilson
```

### Lendo variáveis de ambiente com Python

Você também pode criar variáveis de ambiente fora do Python, no terminal (ou com qualquer outro método), e realizar a leitura delas no Python.

Por exemplo, você pode definir um arquivo `main.py` com o seguinte código:

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")

  @Test
  fun requiresRequestBody() {
    assertTrue(requiresRequestBody("PUT"))
    assertFalse(requiresRequestBody("GET"))
  }

  @Test
  fun hasBody() {
    val request = Request.Builder().url("http://example.com").build()
    val response =
      Response
        .Builder()
        .code(200)
        .message("OK")
        .request(request)
        .protocol(Protocol.HTTP_2)
        .build()
