/// tip | Dica

Se você quiser chamar funções `async` em seus testes além de enviar solicitações à sua aplicação FastAPI (por exemplo, funções de banco de dados assíncronas), dê uma olhada em [Testes assíncronos](../advanced/async-tests.md) no tutorial avançado.

### Несинхронные функции-обработчики пути { #non-async-path-operation-functions }

Вы также можете использовать обычные функции `def` (без `async`) и применять `yield` тем же образом.

FastAPI проследит, чтобы выполнение прошло корректно и не блокировало цикл событий.

Так как в этом случае функция не async, правильным типом возврата будет `Iterable[Item]`:

from fastapi import FastAPI, status

app = FastAPI()


@app.post("/items/", status_code=status.HTTP_201_CREATED)
async def create_item(name: str):

from fastapi import FastAPI, Query

app = FastAPI()


@app.get("/items/")
async def read_items(q: list = Query(default=[])):
    query_items = {"q": q}

from fastapi import FastAPI
from fastapi.responses import ORJSONResponse

app = FastAPI()


@app.get("/items/", response_class=ORJSONResponse)
async def read_items():

from fastapi import FastAPI
from fastapi.middleware.httpsredirect import HTTPSRedirectMiddleware

app = FastAPI()

app.add_middleware(HTTPSRedirectMiddleware)


@app.get("/")
async def main():
