さらに、こうした何千もの *path operations* は、たった3行で表現できるのです:

{* ../../docs_src/security/tutorial002.py hl[30:32] *}

## まとめ

これで、 *path operation関数* の中で直接現在のユーザーを取得できるようになりました。

既に半分のところまで来ています。

あとは、 `username` と `password` を実際にそのユーザーやクライアントに送る、 *path operation* を追加する必要があるだけです。

# Globale Abhängigkeiten

Bei einigen Anwendungstypen möchten Sie möglicherweise Abhängigkeiten zur gesamten Anwendung hinzufügen.

Ähnlich wie Sie [`dependencies` zu den *Pfadoperation-Dekoratoren* hinzufügen](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} können, können Sie sie auch zur `FastAPI`-Anwendung hinzufügen.

In diesem Fall werden sie auf alle *Pfadoperationen* in der Anwendung angewendet:

     * @return received data buffer, or null if timeout
     * @throws IOException if receive fails
     */
    public abstract ByteBuffer receive(int timeout) throws IOException;

    /**
     * Perform RDMA read operation
     *
     * @param localRegion local memory region to read into
     * @param remoteAddress remote memory address
     * @param remoteKey remote memory key
     * @param length number of bytes to read

    /** Performs a GAS operation on {@link AbstractFutureState#waitersField}. */
    abstract @Nullable Waiter gasWaiters(AbstractFutureState<?> future, Waiter update);

    /** Performs a GAS operation on {@link AbstractFutureState#listenersField}. */
    abstract @Nullable Listener gasListeners(AbstractFutureState<?> future, Listener update);

    /** Performs a CAS operation on {@link AbstractFutureState#valueField}. */

        @Test
        @DisplayName("delete operation should work correctly")
        void testDelete() throws CIFSException {
            // When/Then
            assertDoesNotThrow(() -> mockResource.delete(), "Delete operation should not throw exception");
            verify(mockResource).delete();
        }

        @Test
        @DisplayName("copy operation should work correctly")

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 **FastAPI** will know that it has to solve `query_extractor` first, to pass the results of that to `query_or_cookie_extractor` while calling it.

Para alguns tipos de aplicação específicos você pode querer adicionar dependências para toda a aplicação.

De forma semelhante a [adicionar dependências (`dependencies`) em *decoradores de operação de rota*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, você pode adicioná-las à aplicação `FastAPI`.

Nesse caso, elas serão aplicadas a todas as *operações de rota* da aplicação:

        }
    }

    /**
     * Performs RDMA read operation.
     *
     * @param buffer the buffer to read into
     * @param remoteAddress remote memory address
     * @param remoteKey remote access key
     * @param length number of bytes to read
     * @return number of bytes read
     * @throws IOException if operation fails
     */
