## Authentication Flow

A client can request temp. S3 credentials via the STS API. It can authenticate via a client certificate and obtain a access/secret key pair as well as a session token. These credentials are associated to an S3 policy at the MinIO server.

## Overview

MinIO implements an S3 extension to list, stat and download files inside a ZIP file stored in any bucket. A perfect use case scenario is when you have a lot of small files archived in multiple ZIP files. Uploading them is faster than uploading small files individually. Besides, your S3 applications will be able to access to the data with little performance overhead.

            try {
                boost = Float.parseFloat(value);
            } catch (final Exception e) {

これは、パスパラメータ `item_id` が `int` ではない値 `"foo"` だからです。

[http://127.0.0.1:8000/items/4.2](http://127.0.0.1:8000/items/4.2) で見られるように、`int` のかわりに `float` が与えられた場合にも同様なエラーが表示されます。

したがって、同じPythonの型宣言を使用することで、**FastAPI**はデータのバリデーションを行います。

表示されたエラーには、バリデーションが通らなかった箇所が明確に示されていることに注意してください。

これは、APIとやり取りするコードを開発・デバッグする際に非常に役立ちます。
