* `"function"`: start the dependency before the *path operation function* that handles the request, end the dependency after the *path operation function* ends, but **before** the response is sent back to the client. So, the dependency function will be executed **around** the *path operation **function***.

Eso es todo.

Y tiene la misma forma y estructura que todas tus *path operation functions*.

Puedes pensar en ella como una *path operation function* sin el "decorador" (sin el `@app.get("/some-path")`).

Y puede devolver lo que quieras.

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

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

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