* [`Parameter Object` (в спецификации)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object), которое использовалось в FastAPI:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`
* [`Request Body Object`, в поле `content`, в `Media Type Object` (в спецификации)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#media-type-object), которое использовалось в FastAPI:
    * `Body()`

### Указание `root_path` { #providing-the-root-path }

Для этого используйте опцию командной строки `--root-path`, например так:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

### Задання `root_path` { #providing-the-root-path }

Щоб цього досягти, ви можете використати опцію командного рядка `--root-path`, наприклад:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

### Bereitstellung des `root_path` { #providing-the-root-path }

Um dies zu erreichen, können Sie die Kommandozeilenoption `--root-path` wie folgt verwenden:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

* [`Parameter Object` (명세서에 있는)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object)는 FastAPI의 다음 기능에서 쓰였습니다:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`
* [`Request Body Object`, `Media Type Object` (명세서에 있는)의 `content` 필드에 있는](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#media-type-object)는 FastAPI의 다음 기능에서 쓰였습니다:
    * `Body()`
    * `File()`

<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban

$ python main.py

// Error importando sirius, no está instalado 😱
Traceback (most recent call last):

**Hinweis**: Stellen Sie sicher, dass Sie `"fastapi[standard]"` in Anführungszeichen setzen, damit es in allen Terminals funktioniert.

## Beispiel { #example }

### Erstellung { #create-it }

Erstellen Sie eine Datei `main.py` mit:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")
