Vor FastAPI 0.118.0 wurde bei Verwendung einer Abhängigkeit mit `yield` der Exit-Code nach der *Pfadoperation-Funktion* ausgeführt, aber unmittelbar bevor die Response gesendet wurde.

Die Absicht war, Ressourcen nicht länger als nötig zu halten, während darauf gewartet wird, dass die Response durchs Netzwerk reist.

# 추가 모델 { #extra-models }

지난 예제에 이어서, 연관된 모델을 여러 개 갖는 것은 흔한 일입니다.

특히 사용자 모델의 경우에 그러한데, 왜냐하면:

* **입력 모델**은 비밀번호를 가질 수 있어야 합니다.
* **출력 모델**은 비밀번호를 가지면 안 됩니다.
* **데이터베이스 모델**은 아마도 해시 처리된 비밀번호를 가질 필요가 있을 것입니다.

/// danger

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

만약 이게 무엇인지 모르겠다면, [보안 장](security/simple-oauth2.md#password-hashing)에서 "password hash"가 무엇인지 배울 수 있습니다.

///

In this case, it might not be a problem, because it's the same user sending the password.

But if we use the same model for another *path operation*, we could be sending our user's passwords to every client.

/// danger

Never store the plain password of a user or send it in a response like this, unless you know all the caveats and you know what you are doing.

///

## Add an output model { #add-an-output-model }

Neste caso, pode não ser um problema, porque é o mesmo usuário enviando a senha.

Mas se usarmos o mesmo modelo para outra *operação de rota*, poderíamos estar enviando as senhas dos nossos usuários para todos os clientes.

/// danger | Cuidado

Nunca armazene a senha simples de um usuário ou envie-a em uma resposta como esta, a menos que você saiba todas as ressalvas e saiba o que está fazendo.

## 带作用域的 JWT 令牌 { #jwt-token-with-scopes }

现在，修改令牌的*路径操作*以返回请求的作用域。

我们仍然使用 `OAuth2PasswordRequestForm`。它包含 `scopes` 属性，其值是 `list[str]`，包含请求中接收到的每个作用域。

我们把这些作用域作为 JWT 令牌的一部分返回。

/// danger | 危险

为简单起见，此处我们只是把接收到的作用域直接添加到了令牌中。

但在你的应用里，为了安全起见，你应该只添加该用户实际能够拥有的作用域，或你预先定义的作用域。

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[157] *}

現在，修改 token 的路徑操作以回傳所請求的 scopes。

我們仍然使用相同的 `OAuth2PasswordRequestForm`。它包含屬性 `scopes`，其為 `list` 的 `str`，列出請求中收到的每個 scope。

並且我們將這些 scopes 作為 JWT token 的一部分回傳。

/// danger

為了簡化，這裡我們只是直接把接收到的 scopes 加進 token。

但在你的應用中，為了安全性，你應確保只加入該使用者實際可擁有或你預先定義的 scopes。

///

{* ../../docs_src/security/tutorial005_an_py310.py hl[157] *}

Although this release is labeled _alpha_, the only unstable thing in it is our new APIs. This
release has many critical bug fixes and is safe to run in production. We're eager to stabilize our
new APIs so we can get out of alpha.

 *  New: Support Java 21's virtual threads (‘OpenJDK Project Loom’). We changed OkHttp's internals

		return []byte{}
	}

	// Past a certain chunk size it is counterproductive to use
	// larger chunks as the source of the write, as when the source
	// is too large we are basically just thrashing the CPU D-cache.
	// So if the result length is larger than an empirically-found
	// limit (8KB), we stop growing the source string once the limit

  Luckily for Alice, the little magic bottle had now had its full
effect, and she grew no larger:  still it was very uncomfortable,
and, as there seemed to be no sort of chance of her ever getting
out of the room again, no wonder she felt unhappy.

  `It was much pleasanter at home,' thought poor Alice, `when one
wasn't always growing larger and smaller, and being ordered about
by mice and rabbits.  I almost wish I hadn't gone down that
