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.

### Create the callback *path operation* { #create-the-callback-path-operation }

To create the callback *path operation* use the same `APIRouter` you created above.

It should look just like a normal FastAPI *path operation*:

* It should probably have a declaration of the body it should receive, e.g. `body: InvoiceEvent`.

    /**
     * Guesses the content type.
     *
     * @param path
     *            The path. Must not be {@literal null} or an empty string.
     * @return The content type.
     */
    public static String guessContentType(final String path) {
        assertArgumentNotEmpty("path", path);

        final InputStream is = ResourceUtil.getResourceAsStream(path);
        try {

func getFileInfoVersions(xlMetaBuf []byte, volume, path string, inclFreeVersions bool) (FileInfoVersions, error) {
	fivs, err := getAllFileInfoVersions(xlMetaBuf, volume, path, true)
	if err != nil {
		return fivs, err
	}

	// If inclFreeVersions is false, partition the versions in fivs.Versions
	// such that finally fivs.Versions has
