**FastAPI** erstellt für Sie das Objekt vom Typ `BackgroundTasks` und übergibt es als diesen Parameter.

## Eine Taskfunktion erstellen { #create-a-task-function }

Erstellen Sie eine Funktion, die als Hintergrundtask ausgeführt werden soll.

                added("Method", "SourceKt.getBool()"),
                added("Method", "SourceKt.invoke(java.lang.String,java.lang.String,kotlin.jvm.functions.Function1)"),
                added("Method", "SourceKt.isBool()"),

*   `tf.function`:

    *   `tf.function` now uses the Python inspect library directly for parsing the signature of the Python function it is decorated on. This change may break code where the function signature is malformed, but was ignored previously, such as:
        *   Using `functools.wraps` on a function with different signature

  opts->opts.validate_colocation_constraints = enable;
}

// Load a Pluggable Device library.
// On success, returns the handle to library in result and return OK from the
// function. Otherwise return nullptr in result and error Status from the
// function.
//
// If `library_filename` has already been loaded, we return a cached handle.
// Device and Kernels/Ops are registered as globals when a library is loaded
// for the first time.

## `BackgroundTasks` の使用 { #using-backgroundtasks }

まず初めに、`BackgroundTasks` をインポートし、`BackgroundTasks` の型宣言と共に、*path operation function* のパラメーターを定義します:

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[1,13] *}

**FastAPI** は、`BackgroundTasks` 型のオブジェクトを作成し、そのパラメーターに渡します。

## タスク関数の作成 { #create-a-task-function }

バックグラウンドタスクとして実行される関数を作成します。

これは、パラメーターを受け取ることができる単なる標準的な関数です。

{* ../../docs_src/path_operation_advanced_configuration/tutorial001_py310.py hl[6] *}

### Using the *path operation function* name as the operationId { #using-the-path-operation-function-name-as-the-operationid }

If you want to use your APIs' function names as `operationId`s, you can iterate over all of them and override each *path operation's* `operation_id` using their `APIRoute.name`.

Bu şekilde **video** veya **ses** de akıtabilirsiniz; hatta işledikçe üretilip gönderilebilir.

## `yield` ile bir `StreamingResponse` { #a-streamingresponse-with-yield }

*Path operation function* içinde `response_class=StreamingResponse` belirtirseniz, her veri parçasını sırayla göndermek için `yield` kullanabilirsiniz.

{* ../../docs_src/stream_data/tutorial001_py310.py ln[1:23] hl[20,23] *}

            .put(5, "Pinky")
            .put(5, "Clyde")
            .build();

    List<String> badGuys = Arrays.asList("Inky", "Blinky", "Pinky", "Pinky", "Clyde");
    Function<String, Integer> stringLengthFunction =
        new Function<String, Integer>() {
          @Override
          public Integer apply(String input) {
            return input.length();
          }
        };

## Otras Llamadas a Funciones Asíncronas { #other-asynchronous-function-calls }

Al ser la función de test asíncrona, ahora también puedes llamar (y `await`) otras funciones `async` además de enviar requests a tu aplicación FastAPI en tus tests, exactamente como las llamarías en cualquier otro lugar de tu código.

* `"request"`: start the dependency before the *path operation function* that handles the request (similar to when using `"function"`), but end **after** the response is sent back to the client. So, the dependency function will be executed **around** the **request** and response...
