## FastAPI ile JSON Lines Akışı { #stream-json-lines-with-fastapi }

FastAPI ile JSON Lines akışı yapmak için, *path operation function* içinde `return` kullanmak yerine, her öğeyi sırayla üretmek için `yield` kullanabilirsiniz.

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[1:24] hl[24] *}

* operation IDs: IDs de operação
* path (as in URL path): path
* path operation: operação de rota
* path operation function: função de operação de rota
* prefix: prefixo
* request (as in HTTP request): request (do not change if it's already translated to requisição)

**FastAPI** 不強制任何特定的意義。

這裡的資訊作為一個指南，而不是要求。

例如，當使用 GraphQL 時，你通常只使用 `POST` 操作。

///

### 第四步：定義「路徑操作函式」 { #step-4-define-the-path-operation-function }

這是我們的「**路徑操作函式**」：

* **path**：是 `/`。
* **operation**：是 `get`。
* **function**：是裝飾器下面的函式（在 `@app.get("/")` 下面）。

{* ../../docs_src/first_steps/tutorial001_py310.py hl[7] *}

這就是一個 Python 函式。

import org.codelibs.fess.Constants;
import org.codelibs.fess.app.web.api.ApiResult;

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

**FastAPI** создаст объект типа `BackgroundTasks` для вас и передаст его через этот параметр.

## Создание функции для фоновой задачи { #create-a-task-function }

Создайте функцию, которую нужно запустить как фоновую задачу.

Это обычная функция, которая может принимать параметры.
