`UploadFile` имеет следующие методы `async`. Все они вызывают соответствующие файловые методы (используя внутренний `SpooledTemporaryFile`).

* `write(data)`: Записать данные `data` (`str` или `bytes`) в файл.
* `read(size)`: Прочитать количество `size` (`int`) байт/символов из файла.
* `seek(offset)`: Перейти к байту на позиции `offset` (`int`) в файле.

For example, if you had a database session in a dependency with `yield`, the `StreamingResponse` would not be able to use that session while streaming data because the session would have already been closed in the exit code after `yield`.

This behavior was reverted in 0.118.0, to make the exit code after `yield` be executed after the response is sent.

These handlers are in charge of returning the default JSON responses when you `raise` an `HTTPException` and when the request has invalid data.

You can override these exception handlers with your own.

### Override request validation exceptions { #override-request-validation-exceptions }

When a request contains invalid data, **FastAPI** internally raises a `RequestValidationError`.

And it also includes a default exception handler for it.

The following commands set a local alias, validate the server information, create a bucket, copy data to that bucket, and list the contents of the bucket.

```sh
mc alias set local http://localhost:9000 minioadmin minioadmin
mc admin info
mc mb data
mc cp ~/Downloads/mydata data/
mc ls data/
```
