데이터를 보내기 위해, (좀 더 보편적인) `POST`, `PUT`, `DELETE` 혹은 `PATCH` 중에 하나를 사용하는 것이 좋습니다.

`GET` 요청에 본문을 담아 보내는 것은 명세서에 정의되지 않은 행동입니다. 그럼에도 불구하고, 이 방식은 아주 복잡한/극한의 사용 상황에서만 FastAPI에 의해 지원됩니다.

`GET` 요청에 본문을 담는 것은 권장되지 않기에, Swagger UI같은 대화형 문서에서는 `GET` 사용시 담기는 본문에 대한 문서를 표시하지 않으며, 중간에 있는 프록시는 이를 지원하지 않을 수도 있습니다.

## Pydantic의 `BaseModel` 임포트 { #import-pydantics-basemodel }

## Verify the `username` and data shape { #verify-the-username-and-data-shape }

We verify that we get a `username`, and extract the scopes.

And then we validate that data with the Pydantic model (catching the `ValidationError` exception), and if we get an error reading the JWT token or validating the data with Pydantic, we raise the `HTTPException` we created before.

#### A Random Item { #a-random-item }

With `data.items()` we get an <dfn title="Something we can iterate on with a for loop, like a list, set, etc.">iterable object</dfn> with tuples containing the key and value for each dictionary item.

We convert this iterable object into a proper `list` with `list(data.items())`.

    ImmutableList<K> keyList = keySet.asList();
    for (int i = 0; i < size(); i++) {
      action.accept(keyList.get(i), valueList.get(i));
