## 创建 `get_current_user` 依赖项

创建 `get_current_user` 依赖项。

还记得依赖项支持子依赖项吗？

`get_current_user` 使用 `oauth2_scheme` 作为依赖项。

与之前直接在路径操作中的做法相同，新的 `get_current_user` 依赖项从子依赖项 `oauth2_scheme` 中接收 `str` 类型的 `token`：

```Python hl_lines="25"
{!../../../docs_src/security/tutorial002.py!}
```

## 获取用户

The `oauth2_scheme` variable is an instance of `OAuth2PasswordBearer`, but it is also a "callable".

It could be called as:

```Python
oauth2_scheme(some, parameters)
```

So, it can be used with `Depends`.

### Use it

    email: str | None = None
    full_name: str | None = None
    disabled: bool | None = None


class UserInDB(User):
    hashed_password: str


pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_scheme = OAuth2PasswordBearer(tokenUrl="token")

app = FastAPI()


def verify_password(plain_password, hashed_password):
    return pwd_context.verify(plain_password, hashed_password)

    full_name: Union[str, None] = None
    disabled: Union[bool, None] = None


class UserInDB(User):
    hashed_password: str


pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

oauth2_scheme = OAuth2PasswordBearer(
    tokenUrl="token",
    scopes={"me": "Read information about the current user.", "items": "Read items."},
)

app = FastAPI()

    ```

## `get_current_user` 의존성 생성하기

의존성 `get_current_user`를 만들어 봅시다.

의존성이 하위 의존성을 가질 수 있다는 것을 기억하십니까?

`get_current_user`는 이전에 생성한 것과 동일한 `oauth2_scheme`과 종속성을 갖게 됩니다.

이전에 *경로 작동*에서 직접 수행했던 것과 동일하게 새 종속성 `get_current_user`는 하위 종속성 `oauth2_scheme`에서 `str`로 `token`을 수신합니다.
