### `RequestValidationError` vs `ValidationError`

    如果您觉得现在还用不到以下技术细节，可以先跳过下面的内容。


`RequestValidationError` 是 Pydantic 的 <a href="https://docs.pydantic.dev/latest/concepts/models/#error-handling" class="external-link" target="_blank">`ValidationError`</a> 的子类。

    message = "moved to val",
    replaceWith = ReplaceWith(expression = "url"),
    level = DeprecationLevel.ERROR,
  )
  fun url(): HttpUrl = url

  @JvmName("-deprecated_method")
  @Deprecated(
    message = "moved to val",
    replaceWith = ReplaceWith(expression = "method"),
    level = DeprecationLevel.ERROR,
  )
  fun method(): String = method

  @JvmName("-deprecated_headers")
  @Deprecated(

Now, get the user data from the (fake) database, using the `username` from the form field.

If there is no such user, we return an error saying "Incorrect username or password".

For the error, we use the exception `HTTPException`:
