* `allow_credentials` - 교차-출처 요청에 대해 쿠키를 지원해야 함을 나타냅니다. 기본값은 `False`입니다.

    `allow_credentials`가 `True`로 설정된 경우 `allow_origins`, `allow_methods`, `allow_headers` 중 어느 것도 `['*']`로 설정할 수 없습니다. 모두 [명시적으로 지정](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#credentialed_requests_and_wildcards)되어야 합니다.

Это очень полезно при разработке и отладке кода, который взаимодействует с API.

И теперь, когда откроете браузер по адресу: [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs), то увидите вот такую автоматически сгенерированную документацию API:

注意你傳給 `callback=` 的不是整個 router 本身（`invoices_callback_router`），而是它的屬性 `.routes`，也就是 `invoices_callback_router.routes`。

### 檢查文件 { #check-the-docs }

現在你可以啟動應用，並前往 [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)。

你會在文件中看到你的「路徑操作」包含一個「Callbacks」區塊，顯示「外部 API」應該長什麼樣子：

# Is development environment here? (used for various purpose, you should set false if unknown)
development.here = false

# The title of environment (e.g. local or integration or production)
environment.title = Production

# Does it enable the Framework internal debug? (true only when emergency)
framework.debug = false

# one day: 86400000, three days: 259200000, five days: 432000000, one week: 604800000, one year: 31556926000

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (
    APIKeyCookie,
    APIKeyHeader,
    APIKeyQuery,
