/// tip

`Response` parametresini kullanmak yerine doğrudan bir response döndürürseniz, FastAPI onu olduğu gibi (doğrudan) döndürür.

Bu yüzden, verinizin doğru tipte olduğundan emin olmanız gerekir. Örneğin `JSONResponse` döndürüyorsanız, verinin JSON ile uyumlu olması gerekir.

Ayrıca `response_model` tarafından filtrelenmesi gereken bir veriyi göndermediğinizden de emin olun.

			continue

# Events testen: Lifespan und Startup – Shutdown { #testing-events-lifespan-and-startup-shutdown }

Wenn Sie `lifespan` in Ihren Tests ausführen müssen, können Sie den `TestClient` mit einer `with`-Anweisung verwenden:

{* ../../docs_src/app_testing/tutorial004_py310.py hl[9:15,18,27:28,30:32,41:43] *}

Estos ataques aprovechan que los navegadores permiten que los scripts envíen requests sin hacer un preflight de CORS cuando:

* no tienen un header `Content-Type` (p. ej. usando `fetch()` con un body `Blob`)
* y no envían credenciales de autenticación.

Este tipo de ataque es relevante principalmente cuando:

from fastapi import FastAPI, Response, status

app = FastAPI()

tasks = {"foo": "Listen to the Bar Fighters"}


@app.put("/get-or-create-task/{task_id}", status_code=200)
def get_or_create_task(task_id: str, response: Response):
    if task_id not in tasks:
        tasks[task_id] = "This didn't exist before"
        response.status_code = status.HTTP_201_CREATED
