## 包含 `yield`、`HTTPException`、`except` 和后台任务的依赖项 { #dependencies-with-yield-httpexception-except-and-background-tasks }

带有 `yield` 的依赖项随着时间演进以涵盖不同的用例并修复了一些问题。

在那之前，只支援使用單一範例的關鍵字 `example`。OpenAPI 3.1.0 仍然支援 `example`，但它已被棄用，且不是 JSON Schema 標準的一部分。因此建議你將 `example` 遷移為 `examples`。🤓

## `Field` 其他參數 { #field-additional-arguments }

在 Pydantic 模型中使用 `Field()` 時，你也可以宣告額外的 `examples`：
