# Parâmetros de path e validações numéricas { #path-parameters-and-numeric-validations }

Da mesma forma que você pode declarar mais validações e metadados para parâmetros de consulta com `Query`, você pode declarar o mesmo tipo de validações e metadados para parâmetros de path com `Path`.

## Importe `Path` { #import-path }

Primeiro, importe `Path` de `fastapi`, e importe `Annotated`:

# 路徑參數與數值驗證 { #path-parameters-and-numeric-validations }

就像使用 `Query` 為查詢參數宣告更多驗證與中繼資料一樣，你也可以用 `Path` 為路徑參數宣告相同類型的驗證與中繼資料。

## 匯入 `Path` { #import-path }

首先，從 `fastapi` 匯入 `Path`，並匯入 `Annotated`：

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[1,3] *}

/// info

FastAPI 在 0.95.0 版加入並開始推薦使用 `Annotated`。

如果你使用更舊的版本，嘗試使用 `Annotated` 會出錯。

#    file-name - an exact leaf filename, regardless of path
