Function NewFileFromURL

tools/filesystem/file.go:101–124

NewFileFromURL creates a new File from the provided url by downloading the resource and load it as BytesReader. Example ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second) defer cancel() file, err := filesystem.NewFileFromURL(ctx, "https://example.com/image.png")

(ctx context.Context, url string)

//
//	file, err := filesystem.NewFileFromURL(ctx, "https://example.com/image.png")
func NewFileFromURL(ctx context.Context, url string) (*File, error) {
	req, err := http.NewRequestWithContext(ctx, "GET", url, nil)
	if err != nil {
		return nil, err
	}

	res, err := http.DefaultClient.Do(req)
	if err != nil {
		return nil, err
	}
	defer res.Body.Close()

	if res.StatusCode < 200 || res.StatusCode > 399 {
		return nil, fmt.Errorf("failed to download url %s (%d)", url, res.StatusCode)
	}

	var buf bytes.Buffer

	if _, err = io.Copy(&buf, res.Body); err != nil {
		return nil, err
	}

	return NewFileFromBytes(buf.Bytes(), path.Base(url))
}
