都沒關係。**FastAPI** 會知道該怎麼做。

## 與 OpenAPI 整合 { #integrated-with-openapi }

你的依賴（以及其子依賴）所宣告的所有請求參數、驗證與需求，都會整合進同一份 OpenAPI 結構中。

因此，互動式文件也會包含來自這些依賴的所有資訊：

`app.add_middleware()` приймає клас middleware як перший аргумент і будь-які додаткові аргументи, що будуть передані цьому middleware.

**FastAPI** містить кілька middleware для поширених випадків використання, далі розглянемо, як їх використовувати.
