Sie können auch den Parameter `route_class` eines `APIRouter` festlegen:

{* ../../docs_src/custom_request_and_route/tutorial003_py310.py hl[26] *}

pkg debug/elf, const R_AARCH64_P32_ABS32 R_AARCH64
pkg debug/elf, const R_AARCH64_P32_ADD_ABS_LO12_NC = 12
pkg debug/elf, const R_AARCH64_P32_ADD_ABS_LO12_NC R_AARCH64
pkg debug/elf, const R_AARCH64_P32_ADR_GOT_PAGE = 26
pkg debug/elf, const R_AARCH64_P32_ADR_GOT_PAGE R_AARCH64
pkg debug/elf, const R_AARCH64_P32_ADR_PREL_LO21 = 10
pkg debug/elf, const R_AARCH64_P32_ADR_PREL_LO21 R_AARCH64
pkg debug/elf, const R_AARCH64_P32_ADR_PREL_PG_HI21 = 11

이렇게 하면 사용자가 API 문서를 열 때마다 애플리케이션이 스키마를 매번 생성하지 않아도 됩니다.

스키마는 한 번만 생성되고, 이후 요청에서는 같은 캐시된 스키마가 사용됩니다.

### 메서드 오버라이드하기 { #override-the-method }

이제 `.openapi()` 메서드를 새 함수로 교체할 수 있습니다.

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[29] *}

### 확인하기 { #check-it }

        dstIndex += 8;
        writeInt8(0L, dst, dstIndex);
        dstIndex += 8;
        /* Samba 2.2.7 needs ATTR_NORMAL
         */
        writeInt2(0x80 | attributes, dst, dstIndex);
        dstIndex += 2;
        /* 6 zeros observed with NT */
        writeInt8(0L, dst, dstIndex);
        dstIndex += 6;

        /* Also observed 4 byte alignment but we stick
         * with the default for jCIFS which is 2 */

Ensuite, **FastAPI** appellera cette surcharge au lieu de la dépendance originale.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip | Astuce

Vous pouvez définir une surcharge de dépendance pour une dépendance utilisée n’importe où dans votre application **FastAPI**.

}

// User-defined self-inverse mapping function
func rot13(r rune) rune {
	const step = 13
	if r >= 'a' && r <= 'z' {
		return ((r - 'a' + step) % 26) + 'a'
	}
	if r >= 'A' && r <= 'Z' {
		return ((r - 'A' + step) % 26) + 'A'
	}
	return r
}

func TestMap(t *testing.T) {
	// Run a couple of awful growth/shrinkage tests
	a := tenRunes('a')

  public void testOrderedGet() {
    TreeMultimap<String, Integer> multimap = createPopulate();
    assertThat(multimap.get("foo")).containsExactly(1, 3, 7).inOrder();
    assertThat(multimap.get("google")).containsExactly(2, 6).inOrder();
    assertThat(multimap.get("tree")).containsExactly(0, 4).inOrder();
  }

  public void testOrderedKeySet() {
    TreeMultimap<String, Integer> multimap = createPopulate();

Und dann ruft **FastAPI** diese Überschreibung anstelle der ursprünglichen Abhängigkeit auf.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip | Tipp

Sie können eine Überschreibung für eine Abhängigkeit festlegen, die an einer beliebigen Stelle in Ihrer **FastAPI**-Anwendung verwendet wird.

E então o **FastAPI** chamará a sobreposição no lugar da dependência original.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip | Dica

Você pode definir uma sobreposição de dependência para uma dependência que é utilizada em qualquer lugar da sua aplicação **FastAPI**.
