### Async Olmayan Path Operation Fonksiyonları { #non-async-path-operation-functions }

Normal `def` fonksiyonlarını (yani `async` olmadan) da kullanabilir ve aynı şekilde `yield` kullanabilirsiniz.

FastAPI, event loop'u bloke etmeyecek şekilde doğru biçimde çalışmasını sağlar.

Bu örnekte fonksiyon async olmadığı için doğru dönüş tipi `Iterable[Item]` olur:

# Without aliases


@app.post("/required-str", operation_id="required_str")
async def read_required_str(p: Annotated[str, Body(embed=True)]):
    return {"p": p}


class BodyModelRequiredStr(BaseModel):
    p: str


@app.post("/model-required-str", operation_id="model_required_str")
async def read_model_required_str(p: BodyModelRequiredStr):
    return {"p": p.p}


@pytest.mark.parametrize(

async def read_optional_list_bytes(p: Annotated[list[bytes] | None, File()] = None):
    return {"file_size": [len(file) for file in p] if p else None}


@app.post("/optional-list-uploadfile")

    p: Annotated[list[UploadFile] | None, File()] = None,

`UploadFile` 具有以下 `async` 方法。它们都会在底层调用对应的文件方法（使用内部的 `SpooledTemporaryFile`）。

* `write(data)`：将 `data` (`str` 或 `bytes`) 写入文件。
* `read(size)`：读取文件中 `size` (`int`) 个字节/字符。
* `seek(offset)`：移动到文件中字节位置 `offset` (`int`)。
    * 例如，`await myfile.seek(0)` 会移动到文件开头。
    * 如果你先运行过 `await myfile.read()`，然后需要再次读取内容时，这尤其有用。
* `close()`：关闭文件。

由于这些方法都是 `async` 方法，你需要对它们使用 await。

例如，在 `async` *路径操作函数* 内，你可以这样获取内容：

@app.get(
    "/a",
    response_class=JsonApiResponse,
    responses={500: {"description": "Error", "model": JsonApiError}},
)
async def a():
    pass  # pragma: no cover


@app.get("/b", responses={500: {"description": "Error", "model": Error}})
async def b():
    pass  # pragma: no cover


client = TestClient(app)


def test_openapi_schema():
    response = client.get("/openapi.json")
