你可以在 `Field`、`Query`、`Body` 等中宣告額外資訊。這些資訊會被包含在產生的 JSON Schema 中。

你會在後續文件中學到更多關於加入額外資訊的內容，特別是在宣告範例時。

/// warning

傳入 `Field` 的額外鍵也會出現在你的應用程式所產生的 OpenAPI schema 中。
由於這些鍵不一定屬於 OpenAPI 規格的一部分，一些 OpenAPI 工具（例如 [OpenAPI 驗證器](https://validator.swagger.io/)）可能無法處理你產生的 schema。

///

## 回顧 { #recap }

你可以使用 Pydantic 的 `Field` 為模型屬性宣告額外的驗證與中繼資料。
