## Use the dependency { #use-the-dependency }

Then we can use the dependency with:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[23] *}

/// info

Notice that we are only declaring one dependency in the *path operation function*, the `query_or_cookie_extractor`.

But you can instruct **FastAPI** to treat it as another body key using `Body`:

{* ../../docs_src/body_multiple_params/tutorial003_an_py310.py hl[23] *}


In this case, **FastAPI** will expect a body like:

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

    private static final long BASE_RETRY_DELAY = 1000;
    private static final long MAX_RETRY_DELAY = 30000;
    private static final int MAX_BACKOFF_SHIFT = 3; // Maximum 8 seconds (2^3 * 1000ms)

    private final DirectoryLeaseManager leaseManager;
    private final ConcurrentHashMap<String, ChangeNotificationHandle> activeWatchers;
    private final ConcurrentHashMap<String, Integer> failureCounts;

            (byte) 19, (byte) 11, (byte) 3 };
    private static int[] totrot = { 1, 2, 4, 6, 8, 10, 12, 14, 15, 17, 19, 21, 23, 25, 27, 28 };

    private static byte[] pc2 = { (byte) 13, (byte) 16, (byte) 10, (byte) 23, (byte) 0, (byte) 4, (byte) 2, (byte) 27, (byte) 14, (byte) 5,
            (byte) 20, (byte) 9, (byte) 22, (byte) 18, (byte) 11, (byte) 3, (byte) 25, (byte) 7, (byte) 15, (byte) 6, (byte) 26, (byte) 19,

burgers = get_burgers(2)
```

---

Если сторонняя библиотека требует вызывать её с ключевым словом `await`,
необходимо писать *функции обработки пути* с использованием `async def`, например:

```Python hl_lines="2-3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```

### Технические подробности

            </annotations>
            <checkTestClasses>true</checkTestClasses>
            <signature>
              <groupId>com.toasttab.android</groupId>
              <artifactId>gummy-bears-api-23</artifactId>
              <version>0.12.0</version>
              <!-- TODO(cpovirk): In principle, it would make sense to *also* test compatibility with JDK 1.8, since guava-android also has JRE users. -->
            </signature>

burgers = get_burgers(2)
```

---

Então, se você está usando uma biblioteca que diz que você pode chamá-la com `await`, você precisa criar as *funções de operação de rota* com `async def`, como em:

```Python hl_lines="2 3"
@app.get('/burgers')
async def read_burgers():
    burgers = await get_burgers(2)
    return burgers
```
