Es handelte sich also um ein komplett zusätzliches System.

Heutzutage ist es nicht sehr populär und wird kaum verwendet.

## OpenAPI

OpenAPI (früher bekannt als Swagger) ist die offene Spezifikation zum Erstellen von APIs (jetzt Teil der Linux Foundation).

**FastAPI** basiert auf **OpenAPI**.

Das ist es, was erlaubt, mehrere automatische interaktive Dokumentations-Oberflächen, Codegenerierung, usw. zu haben.

So, it was a complete additional system.

It is not very popular or used nowadays.

## OpenAPI { #openapi }

OpenAPI (previously known as Swagger) is the open specification for building APIs (now part of the Linux Foundation).

**FastAPI** is based on **OpenAPI**.

That's what makes it possible to have multiple automatic interactive documentation interfaces, code generation, etc.

OkHttp
======

See the [project website][okhttp] for documentation and APIs.

HTTP is the way modern applications network. It’s how we exchange data & media. Doing HTTP
efficiently makes your stuff load faster and saves bandwidth.

OkHttp is an HTTP client that’s efficient by default:

 * HTTP/2 support allows all requests to the same host to share a socket.
 * Connection pooling reduces request latency (if HTTP/2 isn’t available).

- **Resource management** - Proper handling of resources with utilities like `CloseableUtil` and `DisposableUtil`

### Key Architectural Patterns
- **Factory Pattern** - `BeanDescFactory` for creating bean descriptors, `ParameterizedClassDescFactory` for generic type handling
- **Builder Pattern** - `CopyOptions` for configuring bean copying operations with fluent API

Beispiele hierfür finden Sie in den nächsten Kapiteln zu relationalen und NoSQL-Datenbanken, Sicherheit usw.

## **FastAPI**-Kompatibilität

Die Einfachheit des Dependency Injection Systems macht **FastAPI** kompatibel mit:

* allen relationalen Datenbanken
* NoSQL-Datenbanken
* externen Packages
* externen APIs

  - pod eviction API calls returned spurious precondition errors and required a second evict API call to succeed
  - dry-run eviction API calls persisted a DisruptionTarget condition into the pod being evicted ([#116554](https://github.com/kubernetes/kubernetes/pull/116554), [@atiratree](https://github.com/atiratree)) [SIG API Machinery and Testing]

Si abres la documentación automática de la API, tu extensión aparecerá en la parte inferior de la *path operation* específica.

Y si ves el OpenAPI resultante (en `/openapi.json` en tu API), verás tu extensión como parte de la *path operation* específica también:
