接下来，首先将数据放入 Pydantic 的 `UserInDB` 模型。

注意：永远不要保存明文密码，本例暂时先使用（伪）哈希密码系统。

如果密码不匹配，则返回与上面相同的错误。

#### 密码哈希 { #password-hashing }

**哈希**是指，将指定内容（本例中为密码）转换为形似乱码的字节序列（其实就是字符串）。

每次传入完全相同的内容（比如，完全相同的密码）时，得到的都是完全相同的乱码。

但这个乱码无法转换回传入的密码。

##### 为什么使用密码哈希 { #why-use-password-hashing }

原因很简单，假如数据库被盗，窃贼无法获取用户的明文密码，得到的只是哈希值。

这样一来，窃贼就无法在其它应用中使用窃取的密码，要知道，很多用户在所有系统中都使用相同的密码，风险超大。
