## Path-параметры, содержащие пути

Предположим, что есть *операция пути* с путем `/files/{file_path}`.

Но вам нужно, чтобы `file_path` сам содержал *путь*, например, `home/johndoe/myfile.txt`.

Тогда URL для этого файла будет такой: `/files/home/johndoe/myfile.txt`.

### Поддержка OpenAPI

In fact, those blocks of code are not written inside the Markdown, they are Python files in the `./docs_src/` directory.

And those Python files are included/injected in the documentation when generating the site.

### Docs for tests

Most of the tests actually run against the example source files in the documentation.

This helps to make sure that:

* The documentation is up-to-date.

}
```

## Paramètres de chemin contenant des chemins

Disons que vous avez une *fonction de chemin* liée au chemin `/files/{file_path}`.

Mais que `file_path` lui-même doit contenir un *chemin*, comme `home/johndoe/myfile.txt` par exemple.

Donc, l'URL pour ce fichier pourrait être : `/files/home/johndoe/myfile.txt`.

### Support d'OpenAPI

!!! info
    Hug was created by Timothy Crosley, the same creator of <a href="https://github.com/timothycrosley/isort" class="external-link" target="_blank">`isort`</a>, a great tool to automatically sort imports in Python files.

!!! check "Ideas inspiring **FastAPI**"
    Hug inspired parts of APIStar, and was one of the tools I found most promising, alongside APIStar.

* Hỗ trợ **WebSocket**.
* In-process background tasks.
* Startup and shutdown events.
* Client cho kiểm thử xây dựng trên HTTPX.
* **CORS**, GZip, Static Files, Streaming responses.
* Hỗ trợ **Session and Cookie**.
* 100% test coverage.
* 100% type annotated codebase.

## Tính năng của Pydantic

**Spoiler alert**: il tutorial - Guida Utente include:

* Dichiarazione di **parameters** da altri posti diversi come: **headers**, **cookies**, **form fields** e **files**.
* Come stabilire **vincoli di validazione** come `maximum_length` o `regex`.

    ```

## Определите параметры `File`

Создайте параметры `File` так же, как вы это делаете для `Body` или `Form`:

=== "Python 3.9+"

    ```Python hl_lines="9"
    {!> ../../../docs_src/request_files/tutorial001_an_py39.py!}
    ```

=== "Python 3.6+"

    ```Python hl_lines="8"
    {!> ../../../docs_src/request_files/tutorial001_an.py!}
    ```

@pytest.fixture(name="app")
def get_app():
    from docs_src.request_forms_and_files.tutorial001_an import app

    return app


@pytest.fixture(name="client")
def get_client(app: FastAPI):
    client = TestClient(app)
    return client


def test_post_form_no_body(client: TestClient):
    response = client.post("/files/")
    assert response.status_code == 422, response.text
    assert response.json() == IsDict(

}
```

## Pfad Parameter die Pfade enthalten

Angenommen, Sie haben eine *Pfadoperation* mit einem Pfad `/files/{file_path}`.

Aber `file_path` soll selbst einen *Pfad* enthalten, etwa `home/johndoe/myfile.txt`.

Sprich, die URL für diese Datei wäre etwas wie: `/files/home/johndoe/myfile.txt`.

### OpenAPI Unterstützung

# Bigger Applications - Multiple Files

If you are building an application or a web API, it's rarely the case that you can put everything on a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

!!! info
    If you come from Flask, this would be the equivalent of Flask's Blueprints.

## An example file structure

Let's say you have a file structure like this:

```
.
├── app
