Ahora revisemos esos cambios paso a paso.

## Esquema de seguridad OAuth2

El primer cambio es que ahora estamos declarando el esquema de seguridad OAuth2 con dos scopes disponibles, `me` y `items`.

El parámetro `scopes` recibe un `dict` con cada scope como clave y la descripción como valor:

{* ../../docs_src/security/tutorial005_an_py310.py hl[63:66] *}

        // Try to add another - should succeed (warning logged but still returns true)
        Map<String, Object> docMap2 = new HashMap<>();
        docMap2.put("_id", "docid2");
        generator.task = new Tuple3<>("generator1", "docid2", "path2");
        boolean result = thumbnailManager.offer(docMap2);
        assertTrue(result);
    }

    // Test getImageFilename with docMap

            SMBUtil.writeInt2(4, buffer, 0);

            // When
            int read1 = response1.readBytesWireFormat(buffer, 0);
            int read2 = response2.readBytesWireFormat(buffer, 0);

            // Then
            assertEquals(4, read1);
            assertEquals(4, read2);
        }
    }

Os parâmetros `prefix`, `tags`, `responses` e `dependencies` são (como em muitos outros casos) apenas um recurso do **FastAPI** para ajudar a evitar duplicação de código.

///

### Importar as dependências

Este código reside no módulo `app.routers.items`, o arquivo `app/routers/items.py`.

E precisamos obter a função de dependência do módulo `app.dependencies`, o arquivo `app/dependencies.py`.

pek de kolay değil.
