同樣地，也有許多相容工具可用，包括支援多種語言的程式碼產生工具。

## Pydantic { #pydantic }

所有資料驗證都由 [Pydantic](https://docs.pydantic.dev/) 在底層處理，因此你能直接受惠。而且你可以放心使用。

你可以用相同的型別宣告搭配 `str`、`float`、`bool` 與許多更複雜的資料型別。

這些之中的好幾個會在接下來的教學章節中介紹。

## 順序很重要 { #order-matters }

在建立「路徑操作」時，你可能會遇到有固定路徑的情況。

像是 `/users/me`，假設它用來取得目前使用者的資料。

然後你也可能有一個路徑 `/users/{user_id}` 用來依使用者 ID 取得特定使用者的資料。
