変数`oauth2_scheme`は`OAuth2PasswordBearer`のインスタンスですが、「呼び出し可能」です。

次のように、呼ぶことができます:

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

そのため、`Depends`と一緒に使うことができます。

### 使い方

これで`oauth2_scheme`を`Depends`で依存関係に渡すことができます。

{* ../../docs_src/security/tutorial001.py hl[10] *}

この依存関係は、*path operation function*のパラメーター`token`に代入される`str`を提供します。

            **extra,
        )


@dataclass(frozen=True)
class Depends:
    dependency: Optional[Callable[..., Any]] = None
    use_cache: bool = True
    scope: Union[Literal["function", "request"], None] = None


@dataclass(frozen=True)
class Security(Depends):

            // Should not throw exception even if .mvn creation fails
            int result = upgradeGoal.testExecuteWithTargetModel(context, "4.0.0");

            // The exact behavior depends on implementation, but it should handle gracefully
            // and not crash the entire upgrade process
            assertTrue(result >= 0, "Should handle .mvn creation failure gracefully");
        }
    }

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

Сначала импортируйте `OAuth2PasswordRequestForm` и затем используйте её как зависимость с `Depends` в операции пути для `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` — это зависимость-класс, которая объявляет тело формы со следующими полями:

* `username`.

// slice, map, or chan (only). Like new, the first argument is a type, not a
// value. Unlike new, make's return type is the same as the type of its
// argument, not a pointer to it. The specification of the result depends on
// the type:
//
//   - Slice: The size specifies the length. The capacity of the slice is
//     equal to its length. A second integer argument may be provided to

//	w.importDir["vendor/golang.org/x/net/route"] = "<goroot>/src/vendor/golang.org/x/net/route"
//
// Since the set of packages that exist depends on context, the result of
// loadImports also depends on context. However, to improve test running time
// the configuration for each environment is cached across runs.
func (w *Walker) loadImports() {
	if w.context == nil {

            logger.info("");
            infoLine('-');
            String name = event.getProject().getName();
            infoMain("Skipping " + name);
            logger.info("{} was not built because a module it depends on failed to build.", name);

            infoLine('-');
        }
    }

    @Override
    public void projectStarted(ExecutionEvent event) {
        if (logger.isInfoEnabled()) {
            init();

Agora vamos usar os utilitários fornecidos pelo **FastAPI** para lidar com isso.

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

Primeiro, importe `OAuth2PasswordRequestForm` e use-o como uma dependência com `Depends` na *operação de rota* para `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` é uma dependência de classe que declara um corpo de formulário com:

* O `username`.

    from fastapi import Depends, FastAPI

    app = FastAPI()


    async def common_parameters(q: str | None = None, skip: int = 0, limit: int = 100):
        return {"q": q, "skip": skip, "limit": limit}


    @app.get("/items/")
    async def read_items(commons: Annotated[dict, Depends(common_parameters)]):
        return commons
    ```
