Editör değişkenlerin tiplerini bildiğinden, yalnızca otomatik tamamlama değil, hata kontrolleri de sağlar:

### `HTMLResponse`

Usa algum texto ou sequência de bytes e retorna uma resposta HTML. Como você leu acima.

### `PlainTextResponse`

Usa algum texto ou sequência de bytes para retornar uma resposta de texto não formatado.

```Python hl_lines="2  7  9"
{!../../docs_src/custom_response/tutorial005.py!}
```

### `JSONResponse`

///

## 返回与输入相同的数据

现在我们声明一个 `UserIn` 模型，它将包含一个明文密码属性。

```Python hl_lines="9  11"
{!../../docs_src/response_model/tutorial002.py!}
```

我们正在使用此模型声明输入数据，并使用同一模型声明输出数据：

```Python hl_lines="17-18"
{!../../docs_src/response_model/tutorial002.py!}
```

现在，每当浏览器使用一个密码创建用户时，API 都会在响应中返回相同的密码。

在这个案例中，这可能不算是问题，因为用户自己正在发送密码。

但是，如果我们在其他的*路径操作*中使用相同的模型，则可能会将用户的密码发送给每个客户端。
