* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).

この例は冗長に見えるかもしれません。セキュリティとデータモデルユーティリティ関数および *path operation* が同じファイルに混在しているということを覚えておいてください。

しかし、ここに重要なポイントがあります。

セキュリティと依存性注入に関するものは、一度だけ書きます。

そして、それは好きなだけ複雑にすることができます。それでも、一箇所に、一度だけ書くのです。すべての柔軟性を備えます。

しかし、同じセキュリティシステムを使って何千ものエンドポイント（*path operation*）を持つことができます。

そして、それらエンドポイントのすべて（必要な、どの部分でも）がこうした依存関係や、あなたが作成する別の依存関係を再利用する利点を享受できるのです。

さらに、こうした何千もの *path operation* は、たった3行で表現できるのです:

        // Default constructor
    }

    /** System helper for common system operations and utilities. */
    @Resource
    protected SystemHelper systemHelper;

    /** Behavior class for user information database operations. */
    @Resource
    protected UserInfoBhv userInfoBhv;

    /** Behavior class for favorite log database operations. */
    @Resource
    protected FavoriteLogBhv favoriteLogBhv;

 * that can be used for server-side copy operations.

By default, the temporary security credentials created by AssumeRoleWithWebIdentity last for one hour. However, the optional DurationSeconds parameter can be used to specify the validity duration of the generated credentials. This value...

Bu gibi durumlarda, dönüş tipi yerine *path operation decorator* parametresi olan `response_model`’i kullanabilirsiniz.

`response_model` parametresini herhangi bir *path operation* içinde kullanabilirsiniz:

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* vb.
