The mime type data within this file is based on information from various
  sources like Apache Nutch, Apache HTTP Server, the file(1) command, etc.

  Notes:
   * Tika supports a wider range of match types than Freedesktop does
   * Glob patterns must be unique, if there's a clash assign to the most
     popular format
   * The main mime type should be the canonical one, use aliases for any

# 更多模型

书接上文，多个关联模型这种情况很常见。

特别是用户模型，因为：

* **输入模型**应该含密码
* **输出模型**不应含密码
* **数据库模型**需要加密的密码

/// danger | "危险"

千万不要存储用户的明文密码。始终存储可以进行验证的**安全哈希值**。

如果不了解这方面的知识，请参阅[安全性中的章节](security/simple-oauth2.md#password-hashing){.internal-link target=_blank}，了解什么是**密码哈希**。

## 多个模型

下面的代码展示了不同模型处理密码字段的方式，及使用位置的大致思路：

//// tab | Python 3.10+

```Python hl_lines="7  9  14  20  22  27-28  31-33  38-39"

      format: !!python/name:pymdownx.superfences.fence_code_format
  pymdownx.tilde:

  # pymdownx blocks
  pymdownx.blocks.admonition:
    types:
    - note
    - attention
    - caution
    - danger
    - error
    - tip
    - hint
    - warning
    # Custom types
    - info
    - check
  pymdownx.blocks.details:
  pymdownx.blocks.tab:
    alternate_style: True

Je krijgt autocomletion die je voorheen misschien zelfs voor onmogelijk had gehouden. Zoals bijvoorbeeld de `price` key in een JSON body (die genest had kunnen zijn) die afkomstig is van een request.

Je hoeft niet langer de verkeerde keys in te typen, op en neer te gaan tussen de documentatie, of heen en weer te scrollen om te checken of je `username` of toch `user_name` had gebruikt.

### Kort

```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。

/// danger

永远不要存储用户的明文密码，也不要在响应中发送密码。

///

## 添加输出模型

相反，我们可以创建一个有明文密码的输入模型和一个没有明文密码的输出模型：

//// tab | Python 3.10+

```Python hl_lines="9  11  16"

| HOST_PROBE_SNAT_IPV6 | "fd16:9254:7127:1337:ffff:ffff:ffff:ffff" | IPv6 link local ranges are designed to be collision-resistant by default, and so this probably never needs to be overridden |
