The `string()` method on response body is convenient and efficient for small documents. But if the response body is large (greater than 1 MiB), avoid `string()` because it will load the entire document into memory. In that case, prefer to process the body as a stream.

/// info | Info

`**second_user_data` bedeutet:

Nimm die Schlüssel-Wert-Paare des `second_user_data` <abbr title="Dictionary – Zuordnungstabelle: In anderen Sprachen auch Hash, Map, Objekt, Assoziatives Array genannt">Dicts</abbr> und übergebe sie direkt als Schlüsselwort-Argumente. Äquivalent zu: `User(id=4, name="Mary", joined="2018-11-30")`

///

### Editor Unterstützung { #editor-support }

* Einen optionalen Query-Parameter `limit`, der ein `int` ist und standardmäßig `100` ist.

Und dann wird einfach ein <abbr title="Dictionary – Zuordnungstabelle: In anderen Sprachen auch Hash, Map, Objekt, Assoziatives Array genannt">`dict`</abbr> zurückgegeben, welches diese Werte enthält.

FastAPI unterstützt (und empfiehlt die Verwendung von) `Annotated` seit Version 0.95.0.

There are some situations in where it's useful to be able to add custom headers to the HTTP error. For example, for some types of security.

You probably won't need to use it directly in your code.

But in case you needed it for an advanced scenario, you can add custom headers:

{* ../../docs_src/handling_errors/tutorial002_py39.py hl[14] *}

## Install custom exception handlers { #install-custom-exception-handlers }

특히 사용자 모델의 경우에 그러한데, 왜냐하면:

* **입력 모델** 은 비밀번호를 가져야 합니다.
* **출력 모델** 은 비밀번호를 가지면 안됩니다.
* **데이터베이스 모델** 은 해시처리된 비밀번호를 가질 것입니다.

/// danger | 위험

절대 사용자의 비밀번호를 평문으로 저장하지 마세요. 항상 이후에 검증 가능한 "안전한 해시(secure hash)"로 저장하세요.

만약 이게 무엇인지 모르겠다면, [security chapters](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}.에서 비밀번호 해시에 대해 배울 수 있습니다.
