## FastAPI 特性 { #fastapi-features }

**FastAPI** 提供了以下內容：

### 建立在開放標準的基礎上 { #based-on-open-standards }

* 使用 [**OpenAPI**](https://github.com/OAI/OpenAPI-Specification) 來建立 API，包含 <dfn title="也稱為：端點、路由">路徑</dfn>、<dfn title="也稱為 HTTP 方法，例如 POST、GET、PUT、DELETE">操作</dfn>、參數、請求內文、安全性等宣告。
* 使用 [**JSON Schema**](https://json-schema.org/)（因為 OpenAPI 本身就是基於 JSON Schema）自動生成資料模型文件。
* 經過縝密的研究後圍繞這些標準進行設計，而不是事後在已有系統上附加的一層功能。

        * Require authenticating towards Elasticsearch, as Elasticsearch 5.5 by default requires basic authentication
* Rebase hyperkube image on debian-hyperkube-base, based on debian-base. ([#48365](https://github.com/kubernetes/kubernetes/pull/48365), [@ixdy](https://github.com/ixdy))

		return cycles == 1
	}
	return uint32(xxhash.Sum64String(string(h))>>32)%(cycles) == cycle%cycles
}

// addChild will add a child based on its hash.

	if _, ok := e.Children[hash.Key()]; ok {
