# FetchGetUrlFunc

> **注意**: このページはまだ日本語に翻訳されていません。以下は英語の原文です。

```ts theme={null}
type FetchGetUrlFunc: (req, signal?) => Promise<GetUrlResponse>;
```

Used to perform a fetch; use this to override the underlying network fetch layer. In NodeJS, the default uses the
"http" and "https" libraries and in the browser `fetch` is used. If you wish to use Axios, this is how you would
register it.

| `signal`? | `FetchCancelSignal`                                    |

## Returns
