/// note

When defining a <a href="https://docs.pydantic.dev/latest/concepts/types/#unions" class="external-link" target="_blank">`Union`</a>, include the most specific type first, followed by the less specific type. In the example below, the more specific `PlaneItem` comes before `CarItem` in `Union[PlaneItem, CarItem]`.

///

    query: str,
    after: str | None = None,
) -> dict[str, Any]:
    headers = {"Authorization": f"token {settings.github_token.get_secret_value()}"}
    variables = {"after": after}
    response = httpx.post(
        github_graphql_url,
        headers=headers,
        timeout=settings.httpx_timeout,
        json={"query": query, "variables": variables, "operationName": "Q"},
    )
    if response.status_code != 200:

func jsonFloat(f float64) string {
	var tmp [32]byte
	dst := tmp[:0]

	// Convert as if by ES6 number to string conversion.
	// This matches most other JSON generators.
	// See golang.org/issue/6384 and golang.org/issue/14135.
	// Like fmt %g, but the exponent cutoffs are different
	// and exponents themselves are not padded to two digits.
	abs := math.Abs(f)

### Errors

XML error response for this API is similar to [AWS STS AssumeRole](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html#API_AssumeRole_Errors)

## Sample `POST` Request

```
http://minio:9000/?Action=AssumeRole&DurationSeconds=3600&Version=2011-06-15&Policy={"Version":"2012-10-17","Statement":[{"Sid":"Stmt1","Effect":"Allow","Action":"s3:*","Resource":"arn:aws:s3:::*"}]}&AUTHPARAMS
```

* Adicione-a como um "middleware" à sua aplicação **FastAPI**.

Você também pode especificar se o seu backend permite:

* Credenciais (Cabeçalhos de autorização, Cookies, etc).
* Métodos HTTP específicos (`POST`, `PUT`) ou todos eles com o curinga `"*"`.
* Cabeçalhos HTTP específicos ou todos eles com o curinga `"*"`.

{* ../../docs_src/cors/tutorial001_py39.py hl[2,6:11,13:19] *}

// errSignatureMismatch means signature did not match.
var errSignatureMismatch = errors.New("Signature does not match")

// When upload object size is greater than 5G in a single PUT/POST operation.
var errDataTooLarge = errors.New("Object size larger than allowed limit")

// When upload object size is less than what was expected.
var errDataTooSmall = errors.New("Object size smaller than expected")

/// info | Info

Um Daten zu senden, sollten Sie eines von: `POST` (meistverwendet), `PUT`, `DELETE` oder `PATCH` verwenden.

**请求体**是客户端发送给 API 的数据。**响应体**是 API 发送给客户端的数据。

API 基本上肯定要发送**响应体**，但是客户端不一定发送**请求体**。

使用 <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> 模型声明**请求体**，能充分利用它的功能和优点。

/// info | 说明

发送数据使用 `POST`（最常用）、`PUT`、`DELETE`、`PATCH` 等操作。

规范中没有定义使用 `GET` 发送请求体的操作，但不管怎样，FastAPI 也支持这种方式，只不过仅用于非常复杂或极端的用例。

我们不建议使用 `GET`，因此，在 Swagger UI 交互文档中不会显示有关 `GET` 的内容，而且代理协议也不一定支持 `GET`。

///

## 导入 Pydantic 的 `BaseModel`

* `CORSMiddleware` 임포트.
* 허용되는 출처(문자열 형식)의 리스트 생성.
* FastAPI 응용 프로그램에 "미들웨어(middleware)"로 추가.

백엔드에서 다음의 사항을 허용할지에 대해 설정할 수도 있습니다:

* 자격증명 (인증 헤더, 쿠키 등).
* 특정한 HTTP 메소드(`POST`, `PUT`) 또는 와일드카드 `"*"` 를 사용한 모든 HTTP 메소드.
* 특정한 HTTP 헤더 또는 와일드카드 `"*"` 를 사용한 모든 HTTP 헤더.

{* ../../docs_src/cors/tutorial001.py hl[2,6:11,13:19] *}

# レスポンスモデル

*path operations* のいずれにおいても、`response_model`パラメータを使用して、レスポンスのモデルを宣言することができます:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* など。

{* ../../docs_src/response_model/tutorial001.py hl[17] *}

/// note | 備考

`response_model`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation関数* のパラメータではありません。
