How to us proxy with chromedp

Question

I want to take screenshot of (thousands of pages) of website like Amazon. I tried some code but getting captcha or traffic error in screenshot. So I want to add proxy with chromedp.

ctx, cancel := chromedp.NewContext(context.Background())
defer cancel()
chromedp.ProxyServer("http://username:password@proxyserver.com:31280")
chromedp.Run(ctx,
        chromedp.Navigate("http://wtfismyip.com"),
        chromedp.Sleep(3*time.Second),
        chromedp.ActionFunc(func(ctxt context.Context) error {
            _, _, contentRect, err := page.GetLayoutMetrics().Do(ctxt)
            v := page.Viewport{
                X:      contentRect.X,
                Y:      contentRect.Y,
                Width:  contentRect.Width,
                Height: contentRect.Height,
                Scale:  1,
            }
            buf, err := page.CaptureScreenshot().WithClip(&v).Do(ctxt)
            log.Printf("Write %v", "/tmp/ss.png")
            ioutil.WriteFile("/tmp/ss.png", buf, 0644)
            return err
        }))

Tried this as well but not working.

it won't be that simple to avoid captcha because of the captcha is to prevent bots like yours. Why do you want to do that? — kabanek, Aug 12 '19 at 12:11
@kabanek i undestand that. So i just need to pass proxy with chromedp. so is there a way to add proxy with chromedp — SAJIKUMAR j s, Aug 12 '19 at 12:31
Using `chromedp.ProxyServer`, which you already have in your question, so it's not clear what you're asking. Can you show your code? — Adrian, Aug 13 '19 at 13:25
