InvalidArgumentException：未知错误：不支持的协议

Question

我在ArrayList中添加了来自Web页面的所有链接，然后逐一点击所有URL。

public class Redirectionlinked1 
{
    public static List findAllLinks(WebDriver driver)
    { 
        List <WebElement> elementList = new ArrayList();
        elementList = driver.findElements(By.tagName("a"));
        elementList.addAll(driver.findElements(By.tagName("img")));

        List finalList = new ArrayList();
        for(WebElement element : elementList)
        {
            if (element.getAttribute("href") != null)
            {
                finalList.add(element);
            }
        }
        return finalList;
    }

    public static void main(String[] args) throws Exception 
    {
        System.setProperty("webdriver.gecko.driver", "E:\\Softwares\\gecko\\geckodriver-v0.16.1-win64\\geckodriver.exe");
        System.setProperty("webdriver.chrome.driver", "E:\\chromedriver.exe");

        WebDriver driver = new ChromeDriver();
        driver.get(" http://testsite.com");
        List <WebElement > allImages = findAllLinks(driver);

        System.out.println("Total number of elements found " + allImages.size());
        driver = new ChromeDriver ();
        URI uri =null;
        for (WebElement element : allImages) {
        if (!driver.getCurrentUrl().equals(element.getAttribute("href")) && driver.)
        {
            driver.manage().deleteAllCookies();
            driver.get(element.getAttribute("href"));
            driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
            Thread.sleep(500);
            System.out.println(element.getAttribute("href"));
            uri = new URI(driver.getCurrentUrl());
            try 
            {
                if(uri.getHost().equalsIgnoreCase("SpecificDomain.net"))
                {
                    System.out.println(" Redirected URL-->> "+element.getAttribute("href"));
                }
            } 
            catch (Exception e) 
            {
                    e.printStackTrace();
            }
        }
   }
}

代码按预期工作（它在浏览器中启动URL)，因为第一个链接稍后抛出错误：

Windows-7

Java-1.8.1

升级您的selenium web驱动程序。这是webdriver和您的浏览器版本的兼容性问题。我用最新版本的chrome web驱动程序更新了我的pom文件，它起作用了。将chrome web驱动程序升级到3.9.1或更高版本也可以解决这个问题。
