### `UploadFile`

`UploadFile` 的属性如下：

    /**
     * Returned by {@link jcifs.SmbResource#getType()} if the resource this <code>SmbFile</code>
     * represents is a server.
     */
    int TYPE_SERVER = 0x04;
    /**
     * Returned by {@link jcifs.SmbResource#getType()} if the resource this <code>SmbFile</code>
     * represents is a share.
     */
    int TYPE_SHARE = 0x08;

### Instalar `pydantic-settings` { #install-pydantic-settings }

Primero, asegúrate de crear tu [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, actívalo y luego instala el paquete `pydantic-settings`:

<div class="termy">

```console

`TestClient`는 <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>를 기반으로 하고 있으며, 다행히 이를 직접 사용하여 API를 테스트할 수 있습니다.

간단한 예시를 위해 [더 큰 어플리케이션 만들기](../ko/tutorial/bigger-applications.md){.internal-link target=_blank} 와 [테스트](../ko/tutorial/testing.md){.internal-link target=_blank}:에서 다룬 파일 구조와 비슷한 형태를 확인해봅시다:
