Mesela, ideal olarak standart Python tip belirteçlerine dayanması gerektiği açıktı.

Ayrıca, en iyi yaklaşım zaten mevcut olan standartları kullanmaktı.

Sonuç olarak, **FastAPI**'ı kodlamaya başlamadan önce, birkaç ay boyunca OpenAPI, JSON Schema, OAuth2 ve benzerlerinin tanımlamalarını inceledim. İlişkilerini, örtüştükleri noktaları ve farklılıklarını anlamaya çalıştım.

## Tasarım

Als Teil der Erstellung des Anwendungsobjekts wird eine *Pfadoperation* für `/openapi.json` (oder welcher Wert für den Parameter `openapi_url` gesetzt wurde) registriert.

Diese gibt lediglich eine JSON-Response zurück, mit dem Ergebnis der Methode `.openapi()` der Anwendung.

注意，模型属性的类型、默认值及 `Field` 的代码结构与*路径操作函数*的参数相同，只不过是用 `Field` 替换了`Path`、`Query`、`Body`。

///

## 添加更多信息

`Field`、`Query`、`Body` 等对象里可以声明更多信息，并且 JSON Schema 中也会集成这些信息。

*声明示例*一章中将详细介绍添加更多信息的知识。

## 小结

Pydantic 的 `Field` 可以为模型属性声明更多校验和元数据。

```txt
Hello, World from Flask!
```

And if you go to <a href="http://localhost:8000/v2" class="external-link" target="_blank">http://localhost:8000/v2</a> you will see the response from FastAPI:

```JSON
{
    "message": "Hello World"
}
