As all these methods are `async` methods, you need to "await" them.

For example, inside of an `async` *path operation function* you can get the contents with:

```Python
contents = await myfile.read()
```

If you are inside of a normal `def` *path operation function*, you can access the `UploadFile.file` directly, for example:

```Python
contents = myfile.file.read()
```

Supposons que vous souhaitiez utiliser un autre <abbr title="Content Delivery Network - Réseau de diffusion de contenu">CDN</abbr>, par exemple vous voulez utiliser `https://unpkg.com/`.

Cela peut être utile si, par exemple, vous vivez dans un pays qui restreint certaines URL.

Notice that, in this case, the `item` that would be taken from the body is optional. As it has a `None` default value.

## Multiple body parameters { #multiple-body-parameters }

In the previous example, the *path operations* would expect a JSON body with the attributes of an `Item`, like:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

* `allow_origins` - Список источников, на которые разрешено выполнять кросс-доменные запросы. Например, `['https://example.org', 'https://www.example.org']`. Можно использовать `['*']`, чтобы разрешить любые источники.
* `allow_origin_regex` - Регулярное выражение для определения источников, на которые разрешено выполнять кросс-доменные запросы. Например, `'https://.*\.example\.org'`.

that can send requests to a Gradle daemon.
Each daemon runs one request at a time. Generally speaking, the daemons only act in response to a request from a client and do not take any action on their own.
There are some background actions that the daemon takes, for example monitoring system memory, watching for file changes or cleaning up caches.

...and have the code for the tests just like before.

## Testing: extended example { #testing-extended-example }

Now let's extend this example and add more details to see how to test different parts.

### Extended **FastAPI** app file { #extended-fastapi-app-file }

Let's continue with the same file structure as before:

@app.put("/items/{item_id}")
async def update_item(
    *,
    item_id: int,
    item: Item = Body(
        openapi_examples={
            "normal": {
                "summary": "A normal example",
                "description": "A **normal** item works correctly.",
                "value": {
                    "name": "Foo",
                    "description": "A very nice Item",
                    "price": 35.4,

#### Non-calculated values

These are inappropriate uses of lazy types:

```groovy
class Example {
    Property<String> getSomeProperty()

    Example() {
        getSomeProperty().set("value")
        getSomeProperty().disallowChanges()
    }
}

class Example2 {
    Provider<String> getSomeProperty() {
