Das einzig Neue ist `callbacks=invoices_callback_router.routes` als Argument für den *Pfadoperation-Dekorator*. Wir werden als Nächstes sehen, was das ist.

## Dokumentation des Callbacks

Der tatsächliche Callback-Code hängt stark von Ihrer eigenen API-Anwendung ab.

Und er wird wahrscheinlich von Anwendung zu Anwendung sehr unterschiedlich sein.

Es könnten nur eine oder zwei Codezeilen sein, wie zum Beispiel:

```Python

   * protect ourselves from that we want to make sure that tasks don't spin too much waiting for the
   * interrupting thread to complete the protocol.
   */
  /*
   * This test hangs (or maybe is just *very* slow) under Android.
   *
   * TODO(b/218700094): Ideally, get this to pass under Android. Failing that, convince ourselves

	config.Net.TLS.Config.ClientAuth = args.TLS.ClientAuth
	config.Net.TLS.Config.RootCAs = args.TLS.RootCAs

	// These settings are needed to ensure that kafka client doesn't hang on brokers
	// refer https://github.com/IBM/sarama/issues/765#issuecomment-254333355
	config.Producer.Retry.Max = 2
	config.Producer.Retry.Backoff = (1 * time.Second)
	config.Producer.Return.Successes = true

In diesem Fall müssen Sie sich darüber keine Sorgen machen. 🤷

### Beispiele für Strategien für Vorab-Schritte

Es hängt **stark** davon ab, wie Sie **Ihr System bereitstellen**, und hängt wahrscheinlich mit der Art und Weise zusammen, wie Sie Programme starten, Neustarts durchführen, usw.

Hier sind einige mögliche Ideen:

allocated by C.  The most important consideration is not to
constrain future implementations, so the rule is that Go code can
hand a Go pointer to C code but must separately arrange for
Go to hang on to a reference to the pointer until C is done with it.

 *  Fix: Don't leak file handles when a cache disk write fails.

 *  Fix: Don't hang when the public suffix database cannot be loaded. We had a bug where a failure
    reading the public suffix database would cause subsequent reads to hang when they should have
    crashed.

 *  Fix: Avoid `InetAddress.getCanonicalHostName()` in MockWebServer. This avoids problems if the

	sconfig.Net.TLS.Config.ClientAuth = h.kconfig.TLS.ClientAuth
	sconfig.Net.TLS.Config.RootCAs = h.kconfig.TLS.RootCAs

OkHttp 4.x Change Log
=====================

## Version 4.12.0

_2023-10-16_

 *  Fix: Don't hang taking headers for HTTP 103 responses.

 *  Fix: Recover gracefully when a cache entry's certificate is corrupted.

 *  Fix: Fail permanently when there's a failure loading the bundled public suffix database.
    This is the dataset that powers `HttpUrl.topPrivateDomain()`.
