It is designed to have functions that receive two parameters, one "request" and one "response". Then you "read" parts from the request, and "write" parts to the response. Because of this design, it is not possible to declare request parameters and bodies with standard Python type hints as function parameters.

        // Should still write the parameters correctly
        assertEquals(TEST_SID, SMBUtil.readInt2(buffer, 0));
        assertEquals(TEST_BATCH_COUNT, SMBUtil.readInt2(buffer, 2));
        assertEquals(TEST_RESUME_KEY, SMBUtil.readInt4(buffer, 6));

        // Empty filename should result in minimal bytes written
        assertTrue(written >= 12); // At least the fixed parameters
    }

# Body – Felder

So wie Sie zusätzliche Validation und Metadaten in Parametern der **Pfadoperation-Funktion** mittels `Query`, `Path` und `Body` deklarieren, können Sie auch innerhalb von Pydantic-Modellen zusätzliche Validation und Metadaten deklarieren, mittels Pydantics `Field`.

## `Field` importieren

Importieren Sie es zuerst:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

It could be called as:

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

So, it can be used with `Depends`.

### Use it { #use-it }

Now you can pass that `oauth2_scheme` in a dependency with `Depends`.

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

This dependency will provide a `str` that is assigned to the parameter `token` of the *path operation function*.

        final int testWindowSize = 50;
