* 依存関係でさえも依存関係を持つことができ、階層または **依存関係の"グラフ"** を作成することができます。

* フレームワークによってすべて**自動的に処理**されます。
* すべての依存関係はリクエストからのデータを要請できて、**path operationsの制約と自動ドキュメンテーションを拡張できます**。
* 依存関係で定義された *path operation* パラメータも**自動検証**が可能です。
* 複雑なユーザー認証システム、**データベース接続**などのサポート
* **データベース、フロントエンドなどに対する妥協はありません**。それらすべてと簡単に統合できます。

### Update a Hero with `HeroUpdate` { #update-a-hero-with-heroupdate }

We can **update a hero**. For this we use an HTTP `PATCH` operation.

### Einen Helden mit `HeroUpdate` aktualisieren { #update-a-hero-with-heroupdate }

Wir können einen Helden **aktualisieren**. Dafür verwenden wir eine HTTP-`PATCH`-Operation.

### Redirects with HTTPS { #redirects-with-https }

For example, let's say you define a *path operation* `/items/`:

{* ../../docs_src/behind_a_proxy/tutorial001_01_py39.py hl[6] *}

If the client tries to go to `/items`, by default, it would be redirected to `/items/`.

     * changing any bin. The operations must not take any action that could even momentarily
     * cause a concurrent read operation to see inconsistent data. This is made easier by the
     * nature of the read operations in Map. For example, no operation can reveal that the table
     * has grown but the threshold has not yet been updated, so there are no atomicity requirements
     * for this with respect to reads.

	opPlus     = "+"
