Você pode ter qualquer combinação de dependências que você quiser.

O **FastAPI** se encarrega de executá-las na ordem certa.

/// note | Detalhes Técnicos

Tudo isso funciona graças aos <a href="https://docs.python.org/3/library/contextlib.html" class="external-link" target="_blank">gerenciadores de contexto</a> do Python.

O **FastAPI** utiliza eles internamente para alcançar isso.

Da wir für unsere Anwendung einen Proxy mit dem Pfadpräfix `/api/v1` haben, muss das Frontend das OpenAPI-Schema unter `/api/v1/openapi.json` abrufen.

 * <h4>Frameworks</h4>
 *
 * <p>When chaining together a graph of asynchronous operations, you will often find it easier to
 * use a framework. Frameworks automate the process, often adding features like monitoring,
 * debugging, and cancellation. Examples of frameworks include:
 *
 * <ul>

* 安全性和身份验证，包括通过 **JWT 令牌**和 **HTTP 基本身份认证**来支持 **OAuth2**。
* 更进阶（但同样简单）的技巧来声明 **多层嵌套 JSON 模型** （借助 Pydantic）。
* 许多额外功能（归功于 Starlette）比如：
    * **WebSockets**
    * **GraphQL**
    * 基于 HTTPX 和 `pytest` 的极其简单的测试
    * **CORS**
    * **Cookie Sessions**
    * ......以及更多
