# OpenAPI-Webhooks

Es gibt Fälle, in denen Sie Ihren API-Benutzern mitteilen möchten, dass Ihre Anwendung mit einigen Daten *deren* Anwendung aufrufen (ein Request senden) könnte, normalerweise um über ein bestimmtes **Event** zu **benachrichtigen**.

Das bedeutet, dass anstelle des normalen Prozesses, bei dem Benutzer Requests an Ihre API senden, **Ihre API** (oder Ihre Anwendung) **Requests an deren System** (an deren API, deren Anwendung) senden könnte.

Reading a file from disk is normally a costly (slow) operation, so you probably want to do it only once and then reuse the same settings object, instead of reading it for each request.

But every time we do:

```Python
Settings()
```

a new `Settings` object would be created, and at creation it would read the `.env` file again.

If the dependency function was just like:

```Python

//   reference types inside function's body to support legacy code. Do not
//   use them in new code.
// - Every node in the function's body must have all of its inputs (including
//   control inputs). In other words, for every node in the body, each input
//   must be either listed in `inputs` or must come from another node in

非同期コードの操作がはるかに簡単になります。

等価な (またはほとんど同一の) 構文が、最近のバージョンのJavaScript (ブラウザおよびNodeJS) にも最近組み込まれました。

しかし、その前は、非同期コードの処理はかなり複雑で難解でした。

以前のバージョンのPythonでは、スレッドや<a href="https://www.gevent.org/" class="external-link" target="_blank">Gevent</a>が利用できました。しかし、コードは理解、デバック、そして、考察がはるかに複雑です。

以前のバージョンのNodeJS / ブラウザJavaScriptでは、「コールバック」を使用していました。これは、「コールバック地獄」につながります。
