你將在[進階使用者指南 - 設定和環境變數](./advanced/settings.md)中了解更多關於使用環境變數處理**應用程式設定**的資訊。

## `PATH` 環境變數 { #path-environment-variable }

有一個**特殊的**環境變數稱為 **`PATH`**，作業系統（Linux、macOS、Windows）用它來查找要執行的程式。

`PATH` 變數的值是一個長字串，由 Linux 和 macOS 上的冒號 `:` 分隔的目錄組成，而在 Windows 上則是由分號 `;` 分隔的。

例如，`PATH` 環境變數可能如下所示：

//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

### Crea la *path operation* del callback { #create-the-callback-path-operation }

Para crear la *path operation* del callback usa el mismo `APIRouter` que creaste arriba.

Debería verse como una *path operation* normal de FastAPI:

# license that can be found in the LICENSE file.

case "$GOWASIRUNTIME" in
	"wasmedge")
		exec wasmedge --dir=/ --env PWD="$PWD" --env PATH="$PATH" ${GOWASIRUNTIMEARGS:-} "$1" "${@:2}"
		;;
	"wasmer")
		exec wasmer run --dir=/ --env PWD="$PWD" --env PATH="$PATH" ${GOWASIRUNTIMEARGS:-} "$1" -- "${@:2}"
		;;
	"wazero")

Bu durumda, fonksiyon parametresi `q` isteğe bağlı olur ve varsayılan olarak `None` olur.

/// check | Ek bilgi

Ayrıca, **FastAPI** path parametresi olan `item_id`'nin bir path parametresi olduğunu ve `q`'nun path olmadığını fark edecek kadar akıllıdır; dolayısıyla bu bir query parametresidir.
