### OpenAPI

**FastAPI** sinh một "schema" với tất cả API của bạn sử dụng tiêu chuẩn **OpenAPI** cho định nghĩa các API.

#### "Schema"

Một "schema" là một định nghĩa hoặc mô tả thứ gì đó. Không phải code triển khai của nó, nhưng chỉ là một bản mô tả trừu tượng.

#### API "schema"

OpenAPI has a way to define multiple security "schemes".

By using them, you can take advantage of all these standard-based tools, including these interactive documentation systems.

OpenAPI defines the following security schemes:

* `apiKey`: an application specific key that can come from:
    * A query parameter.
    * A header.
    * A cookie.

- Added support for CEL(Common Expression Language) expressions and `additionalProperties` to be used under nested quantifiers in CRD schemas. ([#124381](https://github.com/kubernetes/kubernetes/pull/124381), [@alexzielenski](https://github.com/alexzielenski)) [SIG API Machinery]
- Added support for building Windows kube-proxy container image.

Então, o frontend (que roda no navegador) tentaria acessar `/openapi.json` e não conseguiria obter o OpenAPI schema.

Como temos um proxy com um prefixo de caminho de `/api/v1` para nossa aplicação, o frontend precisa buscar o OpenAPI schema em `/api/v1/openapi.json`.
