# Body - Birden Fazla Parametre { #body-multiple-parameters }

Artık `Path` ve `Query` kullanmayı gördüğümüze göre, request body bildirimlerinin daha ileri kullanım senaryolarına bakalım.

## `Path`, `Query` ve body parametrelerini karıştırma { #mix-path-query-and-body-parameters }

Öncelikle, elbette `Path`, `Query` ve request body parametre bildirimlerini serbestçe karıştırabilirsiniz ve **FastAPI** ne yapacağını bilir.

# Body - Множество параметров { #body-multiple-parameters }

Теперь, когда мы увидели, как использовать `Path` и `Query` параметры, давайте рассмотрим более продвинутые примеры объявления тела запроса.

## Объединение `Path`, `Query` и параметров тела запроса { #mix-path-query-and-body-parameters }

                throw new RuntimeException(e);
            }
        }, "Multiple close operations should not cause issues");

        // Verify iterator still works after multiple closes
        assertFalse(emptyIterator.hasNext(), "Iterator should still work after multiple closes");
        assertNull(emptyIterator.next(), "Iterator should still return null after multiple closes");
    }

    @Test

minio server --address :9003 /data/tenant3
```

### 1.2 Host Multiple Tenants on Multiple Drives (Erasure Code)

Use the following commands to host 3 tenants on multiple drives:

```sh
minio server --address :9001 /disk{1...4}/data/tenant1
minio server --address :9002 /disk{1...4}/data/tenant2

@app.post("/files/")
async def create_files(
    files: Annotated[list[bytes], File(description="Multiple files as bytes")],
):
    return {"file_sizes": [len(file) for file in files]}


@app.post("/uploadfiles/")
async def create_upload_files(
    files: Annotated[
        list[UploadFile], File(description="Multiple files as UploadFile")
    ],
):
    return {"filenames": [file.filename for file in files]}

## Using the same dependency multiple times { #using-the-same-dependency-multiple-times }

If one of your dependencies is declared multiple times for the same *path operation*, for example, multiple dependencies have a common sub-dependency, **FastAPI** will know to call that sub-dependency only once per request.

app = FastAPI()
