So we put them in their own `dependencies` module (`app/dependencies.py`).

We will now use a simple dependency to read a custom `X-Token` header:

//// tab | Python 3.9+

```Python hl_lines="3  6-8" title="app/dependencies.py"
{!> ../../docs_src/bigger_applications/app_an_py39/dependencies.py!}
```

//// tab | Python 3.8+

이를 통해 **여러 위치**에서 **모델을 재사용** 할 수 있고 모든 매개변수에 대한 유효성 검사 및 메타데이터를 한 번에 선언할 수도 있습니다. 😍

/// note | 참고

이 기능은 FastAPI 버전 `0.115.0` 이후부터 지원됩니다. 🤓

///

/// tip | 팁

동일한 기술이 `Query`, `Cookie`, 그리고 `Header`에 적용됩니다. 😎

## Pydantic 모델을 사용한 쿠키

**Pydantic 모델**에 필요한 **쿠키** 매개변수를 선언한 다음, 해당 매개변수를 `Cookie`로 선언합니다:

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}

 *  Breaking: Move `gzip` from `RequestBody` to `Request.Builder`. This new API handles both
    compressing the request body and also adding the corresponding `Content-Encoding` header. Note
    that this function is sensitive to when it is called: the response body must be supplied before
    it can be compressed.

            assertEquals(pathBytes.length, SMBUtil.readInt2(buffer, bodyOffset + 6)); // Path length
        }
    }

    @Test
    @DisplayName("Should correctly calculate path offset from header start")
    void testPathOffsetCalculation() throws Exception {
        // Given
        byte[] buffer = new byte[512];
        int headerStart = 64;

        // When

            request.setOffset(1024L);
            request.setRemainingBytes(500);
            request.setWriteFlags(0x01);

            byte[] buffer = new byte[1024];
            int headerStart = 64; // Simulated header start

            // Execute
            int bytesWritten = request.writeBytesWireFormat(buffer, headerStart);

            // Verify structure

      "coverage" : {
        "per_commit" : [ "linux" ]
      }
    } ]
  }, {
    "testId" : "org.gradle.performance.regression.nativeplatform.NativeBuildPerformanceTest.assemble with header file change",
    "groups" : [ {
      "testProject" : "bigCppApp",
      "coverage" : {
        "per_day" : [ "linux" ]
      }
    }, {
      "testProject" : "bigCppMulti",
      "coverage" : {

            basicAuthList.add(webAuth.getAuthentication());
        }
        paramMap.put(HcHttpClient.AUTHENTICATIONS_PROPERTY, basicAuthList.toArray(new Authentication[basicAuthList.size()]));

        // request header
        final List<RequestHeader> requestHeaderList = requestHeaderService.getRequestHeaderList(getId());
        final List<org.codelibs.fess.crawler.client.http.RequestHeader> rhList = new ArrayList<>();

Y todos usarán la misma conexión WebSocket.

## Usando `Depends` y otros

En endpoints de WebSocket puedes importar desde `fastapi` y usar:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

Funcionan de la misma manera que para otros endpoints de FastAPI/*path operations*:

{* ../../docs_src/websockets/tutorial002_an_py310.py hl[68:69,82] *}
