我们使用这个模型来声明输入，同时也用相同的模型来声明输出：

{* ../../docs_src/response_model/tutorial002_py310.py hl[16] *}

现在，每当浏览器使用密码创建用户时，API 会在响应中返回相同的密码。

在这个场景下，这可能不算问题，因为发送密码的是同一个用户。

但如果我们在其他*路径操作*中使用相同的模型，就可能会把用户的密码发送给每个客户端。

/// danger | 危险

除非你非常清楚所有注意事项并确实知道自己在做什么，否则永远不要存储用户的明文密码，也不要像这样在响应中发送它。

## 添加输出模型 { #add-an-output-model }

相反，我们可以创建一个包含明文密码的输入模型和一个不包含它的输出模型：

   * <p>The entry set is backed by the same data as the multiset, so any change to either is
   * immediately reflected in the other. However, multiset changes may or may not be reflected in
   * any {@code Entry} instances already retrieved from the entry set (this is
   * implementation-dependent). Furthermore, implementations are not required to support

    impacts VM-wide behavior.

 *  New: Reduce contention for applications that make a very high number of concurrent requests.
    Previously OkHttp used its connection pool as a lock when making changes to connections and
    calls. With this change each connection is locked independently.

 *  Upgrade: [Okio 2.7.0][okio_2_7_0].
