'''System.setProperty("webdriver.chrome.driver", "C:/Users/NaqDaq/Downloads/chromedriver_win32/chromedriver.exe"); WebDriver driver = new ChromeDriver();

Vishal,

试试下面的代码，对我有用。

@Test(enabled = true)
public static void amazonActiveLinks() {

    // Browser Initializing
    System.setProperty("webdriver.gecko.driver", "C:\\Software\\geckodriver-v0.19.0-win64\\geckodriver.exe");

    driver = new FirefoxDriver();

    driver.manage().window().maximize();
    driver.manage().deleteAllCookies();

    driver.manage().timeouts().pageLoadTimeout(40, TimeUnit.SECONDS);
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

    driver.get("https://www.amazon.com");

    List<WebElement> linksList = driver.findElements(By.tagName("img"));
    linksList.addAll(driver.findElements(By.tagName("a")));
    System.out.println("The full size of Links and Images are: " + linksList.size());

    String url;
    List<WebElement> activeLinks = new ArrayList<WebElement>();

    for (WebElement link : linksList) {
        url = link.getAttribute("href");
        if (url != null || url != "") {
            activeLinks.add(link);
        }
    }
    System.out.println("The active links and images are--->" + activeLinks.size());

}
