暫時採用這個（外部開發者）的視角，有助於讓你更直覺地決定該把參數、body 的 Pydantic 模型、response 的模型等放在哪裡，對於那個「外部 API」會更清楚。

### 建立一個回呼用的 `APIRouter` { #create-a-callback-apirouter }

先建立一個新的 `APIRouter`，用來放一個或多個回呼。

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[1,23] *}

### 建立回呼的「路徑操作」 { #create-the-callback-path-operation }

要建立回呼的「路徑操作」，就使用你上面建立的同一個 `APIRouter`。

它看起來就像一般的 FastAPI「路徑操作」：

   */
  public static <E extends @Nullable Object> void assertMultisetIsUnmodifiable(
      Multiset<E> multiset, E sampleElement) {
    Multiset<E> copy = LinkedHashMultiset.create(multiset);
    assertCollectionsAreEquivalent(multiset, copy);

    // Multiset is a collection, so we can use all those tests.
    assertCollectionIsUnmodifiable(multiset, sampleElement);

API를 OAuth2 provider와 통합하면 인증을 수행한 뒤 획득한 자격 증명으로 API 문서로 다시 돌아올 수 있습니다. 그리고 실제 OAuth2 인증을 사용해 API와 상호작용할 수 있습니다.

Swagger UI가 이 과정을 백그라운드에서 처리해 주지만, 이를 위해 이 "redirect" 헬퍼가 필요합니다.

### 테스트용 *경로 처리* 만들기 { #create-a-path-operation-to-test-it }

이제 모든 것이 제대로 동작하는지 테스트할 수 있도록 *경로 처리*를 하나 만드세요:
