mais qui n'est pas appelé lorsqu'un autre fichier l'importe, comme dans :

```Python
from myapp import app
```

#### Pour davantage de détails

Imaginons que votre fichier s'appelle `myapp.py`.

Si vous l'exécutez avec :

<div class="termy">

```console
$ python myapp.py
```

<div class="termy">

```console
$ python myapp.py
```

</div>

mas não é chamado quando outro arquivo o importa, como em:

```Python
from myapp import app
```

#### Mais detalhes { #more-details }

Digamos que seu arquivo se chama `myapp.py`.

Se você executá-lo com:

<div class="termy">

```console
$ python myapp.py
```

你也可以在直接返回`Response`时添加头部。

按照[直接返回响应](response-directly.md){.internal-link target=_blank}中所述创建响应，并将头部作为附加参数传递：

{* ../../docs_src/response_headers/tutorial001.py hl[10:12] *}


/// note | 技术细节

你也可以使用`from starlette.responses import Response`或`from starlette.responses import JSONResponse`。

**FastAPI**提供了与`fastapi.responses`相同的`starlette.responses`，只是为了方便开发者。但是，大多数可用的响应都直接来自Starlette。

由于`Response`经常用于设置头部和cookies，因此**FastAPI**还在`fastapi.Response`中提供了它。

First, copy the public key block below into a new file called `gradle_pubkey.asc`, then import it with this command:

```bash
gpg --import gradle_pubkey.asc
```

Alternatively, you can fetch the key directly from a key server:

```bash
gpg --keyserver hkps://keys.openpgp.org --recv-keys 1BD97A6A154E7810EE0BC832E2F38302C8075E3D
```
