    * UUID.

모든 검증은 견고하면서 잘 확립된 **Pydantic**에 의해 처리됩니다.

### 보안과 인증

보안과 인증이 통합되어 있습니다. 데이터베이스나 데이터 모델과의 타협없이 사용할 수 있습니다.

다음을 포함하는, 모든 보안 스키마가 OpenAPI에 정의되어 있습니다.

* HTTP Basic.
* **OAuth2** (**JWT tokens** 또한 포함). [OAuth2 with JWT](tutorial/security/oauth2-jwt.md){.internal-link target=\_blank}에 있는 자습서를 확인해 보세요.
* 다음에 들어 있는 API 키:
    * 헤더.
    * 매개변수.
    * 쿠키 및 그 외.

* Bảo mật và xác thực, hỗ trợ **OAuth2**(với **JWT tokens**) và **HTTP Basic**.
* Những kĩ thuật nâng cao hơn (nhưng tương đối dễ) để định nghĩa **JSON models lồng nhau** (cảm ơn Pydantic).

    ImmutableList.Builder<String> zat = ImmutableList.<String>builder().add("c", "d");
    ImmutableList<String> list = zis.combine(zat).build();
    assertEquals(asList("a", "b", "c", "d"), list);
  }

  // Basic tests

  @GwtIncompatible // NullPointerTester
  public void testNullPointers() {
    NullPointerTester tester = new NullPointerTester();

   *
   * (The index actually stored is the index of the key in alternatingKeysAndValues, which is
   * double the index of the entry in entrySet.asList.)
   *
   * The basic data structure is described in https://en.wikipedia.org/wiki/Open_addressing.
   * The pointer to a key is stored in hashTable[Hashing.smear(key.hashCode()) % table.length],

# Development - Contributing

First, you might want to see the basic ways to [help FastAPI and get help](help-fastapi.md){.internal-link target=_blank}.

## Developing

If you already cloned the <a href="https://github.com/fastapi/fastapi" class="external-link" target="_blank">fastapi repository</a> and you want to deep dive in the code, here are some guidelines to set up your environment.

### Virtual environment

* Zabezpieczenia i autentykacja, wliczając wsparcie dla **OAuth2** z **tokenami JWT** oraz autoryzacją **HTTP Basic**.
* Bardziej zaawansowane (ale równie proste) techniki deklarowania **głęboko zagnieżdżonych modeli JSON** (dzięki Pydantic).
* Wiele dodatkowych funkcji (dzięki Starlette) takie jak:
    * **WebSockety**
    * **GraphQL**
