	// Metrics v3
	metricsV3Server := newMetricsV3Server(auth)

	// Register metrics v3 handler. It also accepts an optional query

In this example above, the input model is a Pydantic v1 model, and the output model (defined in `response_model=ItemV2`) is a Pydantic v2 model.

### Pydantic v1 parameters { #pydantic-v1-parameters }

If you need to use some of the FastAPI-specific tools for parameters like `Body`, `Query`, `Form`, etc. with Pydantic v1 models, you can import them from `fastapi.temp_pydantic_v1_params` while you finish the migration to Pydantic v2:

**Purpose**: Test FilenameExtractor edge cases and new documentation.

**Key Test Areas**:
- Parameter handling (null, empty, missing)
- Special character handling
- Input stream validation (not consumption)
- Edge cases (long filenames, paths, whitespace)

**Test Count**: 10 tests

**Key Scenarios**:
- ✅ Valid filename extraction
- ✅ Null parameters handling
- ✅ Empty/missing resource name
- ✅ Special characters in filename (Japanese, paths)

        assertEquals(0, dst[35], "Reserved byte should be 0");
    }

    @Test
    void testWriteParameterWordsWireFormat_ZeroCounts() {
        // Test with zero parameter and data counts to check conditional logic.
        smbComNtTransaction.command = ServerMessageBlock.SMB_COM_NT_TRANSACT;
        smbComNtTransaction.parameterCount = 0;
        smbComNtTransaction.dataCount = 0;

In diesem Fall können Sie diese Funktion in **FastAPI** mit dem Parameter `separate_input_output_schemas=False` deaktivieren.

/// info | Info

Unterstützung für `separate_input_output_schemas` wurde in FastAPI `0.102.0` hinzugefügt. 🤓
