### 자신의 유저 데이터 가져오기

이제 `/users/me` 경로에 `GET` 작업을 진행합시다.

다음과 같은 사용자 데이터를 얻을 수 있습니다:

```JSON
{
  "username": "johndoe",
  "email": "******@****.***",
  "full_name": "John Doe",
  "disabled": false,
  "hashed_password": "fakehashedsecret"

* `allow_methods` – Eine Liste von HTTP-Methoden, die für Cross-Origin-Requests erlaubt sein sollen. Standardmäßig `['GET']`. Sie können `['*']` verwenden, um alle Standardmethoden zu erlauben.

```Python
results = await some_library()
```

Entonces, declara tus *path operation functions* con `async def` así:

```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`.

//// tab | Windows PowerShell

<div class="termy">

```console
$ Get-Command python

C:\Users\user\code\awesome-project\.venv\Scripts\python
```

</div>

////

bedeutet das, dass das `python`-Programm, das verwendet wird, das in der **virtuellen Umgebung** ist.

Sie verwenden `which` auf Linux und macOS und `Get-Command` in Windows PowerShell.

```Python
results = await some_library()
```

Тогда объявляйте *функции-обработчики пути* с `async def`, например:

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

/// note | Примечание

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