Um sicherzustellen, dass alles korrekt funktioniert, ist es besser, die erlaubten Origins explizit anzugeben.

## `CORSMiddleware` verwenden { #use-corsmiddleware }

Sie können das in Ihrer **FastAPI**-Anwendung mit der `CORSMiddleware` konfigurieren.

* Importieren Sie `CORSMiddleware`.
* Erstellen Sie eine Liste der erlaubten Origins (als Strings).

* Default değeri `100` olan `int` tipinde bir `limit` query parametresi.

Her iki durumda da veriler dönüştürülecek, doğrulanacak, OpenAPI şemasında dokümante edilecek, vb.

## Kullanalım { #use-it }

Artık bu class'ı kullanarak dependency'nizi tanımlayabilirsiniz.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

	logger.LogOnceIf(ctx, logSubsys, err, id, errKind...)
}

// ErrTargetsOffline - Indicates single/multiple target failures.
var ErrTargetsOffline = errors.New("one or more targets are offline. Please use `mc admin info --json` to check the offline targets")

// TestSubSysNotificationTargets - tests notification targets of given subsystem

Но если вы хотите передавать в потоке чистые бинарные данные или строки, ниже показано, как это сделать.

/// info | Информация

Добавлено в FastAPI 0.134.0.

///

## Варианты использования { #use-cases }

Это можно использовать, если вы хотите стримить чистые строки, например, напрямую из вывода сервиса **AI LLM**.

{* ../../docs_src/dataclasses_/tutorial001_py310.py hl[1,6:11,18:19] *}

这仍然得益于 **Pydantic**，因为它对 [`dataclasses` 的内置支持](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel)。

因此，即便上面的代码没有显式使用 Pydantic，FastAPI 也会使用 Pydantic 将那些标准数据类转换为 Pydantic 风格的 dataclasses。

并且，它仍然支持以下功能：

* 数据验证
* 数据序列化
* 数据文档等

Wenn Sie jedoch `Query`, `Path`, `Depends`, `Security` und andere von `fastapi` importieren, handelt es sich tatsächlich um Funktionen, die spezielle Klassen zurückgeben.

///

## `SecurityScopes` verwenden { #use-securityscopes }

Aktualisieren Sie nun die Abhängigkeit `get_current_user`.

Das ist diejenige, die von den oben genannten Abhängigkeiten verwendet wird.
