How to download picture like downloading other file types?

[ZeroOut]

something like this:

chromedp.Run(ctx, page.SetDownloadBehavior(page.SetDownloadBehaviorBehaviorAllow).WithDownloadPath(local_path), chromedp.Navigate(url_to_picture))

Something like this:

func (downloader *Downloader) Download(url string) ([]byte, error) {
	tab := NewTabForChrome(downloader.Context)

	done := make(chan bool)

	var requestId network.RequestID

	chromedp.ListenTarget(tab.TabContext, func(ev interface{}) {

		switch ev := ev.(type) {

		case *network.EventRequestWillBeSent:
			req := ev.Request
			if req.URL == url {
				requestId = ev.RequestID
			}

		case *network.EventLoadingFinished:
			if ev.RequestID == requestId {
				close(done)
			}
		}
	})

	err := chromedp.Run(tab.TabContext, chromedp.Tasks{
		page.SetDownloadBehavior(page.SetDownloadBehaviorBehaviorAllow).WithDownloadPath(os.TempDir()),
		chromedp.Navigate(url),
	})
	if err != nil {
		return nil, err
	}

	<-done

	var bytes []byte
	err = chromedp.Run(tab.TabContext, chromedp.ActionFunc(func(cxt context.Context) error {
		bytes, err = network.GetResponseBody(requestId).Do(cxt)
		return err
	}))

	err = tab.Close()
	if err != nil {
		return nil, err
	}

	return bytes, nil
}

@Hecatoncheir thanks for the example. Closing this out.
