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

### Mais detalhes técnicos

Você deve ter observado que `await` pode ser usado somente dentro de funções definidas com `async def`.

```

В этом случае *функции обработки пути* необходимо объявлять с использованием синтаксиса `async def`:

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

!!! note
    `await` можно использовать только внутри функций, объявленных с использованием `async def`.

---

Если вы обращаетесь к сторонней библиотеке, которая с чем-то взаимодействует

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

### More technical details

You might have noticed that `await` can only be used inside of functions defined with `async def`.

`await` in yalnızca `async def` ile tanımlanan fonksıyonların içinde kullanılabileceğini fark etmişsinizdir.

Ama aynı zamanda, `async def` ile tanımlanan fonksiyonların "await" ile beklenmesi gerekir. Bu nedenle, "`async def` içeren fonksiyonlar yalnızca "`async def` ile tanımlanan fonksiyonların içinde çağrılabilir.


Yani yumurta mı tavukdan, tavuk mu yumurtadan gibi ilk `async` fonksiyonu nasıl çağırılır?

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

!!! note "Nota"
    Solo puedes usar `await` dentro de funciones creadas con `async def`.

---

    return burgers
```

### 更多技术细节

您可能已经注意到，`await` 只能在 `async def` 定义的函数内部使用。

但与此同时，必须"等待"通过 `async def` 定义的函数。因此，带 `async def` 的函数也只能在 `async def` 定义的函数内部调用。

那么，这关于先有鸡还是先有蛋的问题，如何调用第一个 `async` 函数？

如果您使用 **FastAPI**，你不必担心这一点，因为"第一个"函数将是你的路径操作函数，FastAPI 将知道如何做正确的事情。

但如果您想在没有 FastAPI 的情况下使用 `async` / `await`，则可以这样做。

### 编写自己的异步代码

// along with this program.  If not, see <http://www.gnu.org/licenses/>.

package dsync

import (
	"fmt"
	"io"
	"net/http"
	"net/http/httptest"
	"sync"
	"sync/atomic"
	"time"

	"github.com/minio/mux"
)

const numberOfNodes = 5

var (
	ds          *Dsync
	nodes       = make([]*httptest.Server, numberOfNodes) // list of node IP addrs or hostname with ports.

Vous avez donc compris que `await` peut seulement être utilisé dans des fonctions définies avec `async def`.

Mais en même temps, les fonctions définies avec `async def` doivent être appelées avec `await` et donc dans des fonctions définies elles aussi avec `async def`.

Vous avez donc remarqué ce paradoxe d'oeuf et de la poule, comment appelle-t-on la première fonction `async` ?
