### Nicht-async-*Pfadoperation-Funktionen* { #non-async-path-operation-functions }

Sie können auch normale `def`-Funktionen (ohne `async`) verwenden und `yield` genauso einsetzen.

FastAPI stellt sicher, dass sie korrekt ausgeführt wird, sodass sie die Event Loop nicht blockiert.

* `PATCH`
* `TRACE`

HTTP protokolünde, her bir path ile bu "method"lardan biri (veya birden fazlası) ile iletişim kurabilirsiniz.

---

API oluştururken, normalde belirli bir aksiyon için bu spesifik HTTP method'larını kullanırsınız.

Normalde şunları kullanırsınız:

* `POST`: veri oluşturmak için.
* `GET`: veri okumak için.
* `PUT`: veriyi güncellemek için.
* `DELETE`: veriyi silmek için.

                display = ParameterDisplay.NORMAL,
                allowEmpty = true,
                description = "The extra gradle parameters you want to pass to this build, e.g. `-PrerunAllTests` or `--no-build-cache`",
            )
            text(
                "reverse.dep.*.additional.gradle.parameters",
                "",
                display = ParameterDisplay.NORMAL,
                allowEmpty = true,

	// Holds info about when the entry was created first.
	CreationDate time.Time `json:"creationDate"`

	// When a SRV record with a "Host: IP-address" is added, we synthesize
	// a srv.Target domain name.  Normally we convert the full Key where
	// the record lives to a DNS name and use this as the srv.Target. When
	// TargetStrip > 0 we strip the left most TargetStrip labels from the
	// DNS name.

## La aplicación normal de **FastAPI** { #the-normal-fastapi-app }

Primero veamos cómo se vería la aplicación API normal antes de agregar el callback.

Tendrá una *path operation* que recibirá un cuerpo `Invoice`, y un parámetro de query `callback_url` que contendrá la URL para el callback.

Esta parte es bastante normal, probablemente ya estés familiarizado con la mayor parte del código:

  public void testNoExceptionsThrown() throws IOException {
    Closer closer = new Closer(suppressor);

    TestCloseable c1 = closer.register(TestCloseable.normal());
    TestCloseable c2 = closer.register(TestCloseable.normal());
    TestCloseable c3 = closer.register(TestCloseable.normal());

    assertFalse(c1.isClosed());
    assertFalse(c2.isClosed());
    assertFalse(c3.isClosed());

    closer.close();

      redundantOpCount >= lruEntries.size
  }

  /**
   * Drops the entry for [key] if it exists and can be removed. If the entry for [key] is currently
   * being edited, that edit will complete normally but its value will not be stored.
   *
   * @return true if an entry was removed.
   */
  @Synchronized
  @Throws(IOException::class)
  fun remove(key: String): Boolean {
    initialize()

Elle peut être une fonction asynchrone (`async def`) ou une fonction normale (`def`), **FastAPI** saura la gérer correctement.

Dans cet exemple, la fonction de tâche écrira dans un fichier (afin de simuler un envoi d'email).

L'opération d'écriture n'utilisant ni `async` ni `await`, on définit la fonction avec un `def` normal.
