Java Selenium Webdriver连接被拒绝

Question

我的selenium WebDriver上出现了一个非常常见的连接拒绝错误。几周前也在执行相同的代码。

我一直在翻阅现有的帖子，并尝试更新geckodriver和FireFox，但没有任何效果。我可以在运行相同版本的驱动程序、浏览器和库等的另一台计算机上运行相同的代码，如何才能找到这台计算机特有的原因？错误在下面。

我甚至可以运行下面的基本代码。

enter code here
package seleniumPrograms;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.firefox.FirefoxDriver;
    import org.openqa.selenium.remote.DesiredCapabilities;

    public class Gecko_Driver {
        public static void main(String[] args)  {
             System.out.println("Debug 1");
             DesiredCapabilities capabilities=DesiredCapabilities.firefox();
             System.out.println("Debug 2");
             capabilities.setCapability("marionette", true);
             System.out.println("Debug 3");
             WebDriver driver = new FirefoxDriver(capabilities);
             System.out.println("Debug 4");
             driver.get("http://www.google.com");

             driver.manage().window().maximize();  
             driver.quit();
        }
 }

以铬为例。

@Test
        public void testGoogleSearch() throws InterruptedException {
          // Optional, if not specified, WebDriver will search your path for chromedriver.
          System.setProperty("webdriver.chrome.driver", "C:\\chromedriver_win32\\chromedriver.exe");

          WebDriver driver = new ChromeDriver();
          driver.get("http://www.google.com/xhtml");
          Thread.sleep(5000);  // Let the user actually see something!
          WebElement searchBox = driver.findElement(By.name("q"));
          searchBox.sendKeys("ChromeDriver");
          searchBox.submit();
          Thread.sleep(5000);  // Let the user actually see something!
          driver.quit();
        }

我们的安全部门引入了一个策略，阻止对执行Geckodriver.exe的访问。这是通过尝试从cmd运行而识别的。不知道为什么我没有在gecko的IDE中得到有意义的错误（被组策略阻止），我确实得到了chrome和IE的这个错误。为了使用驱动程序，它需要保存在程序文件中，尽管这可能是特定于我的情况。如果Geckodriver出现这个错误，我建议尝试从cmd执行它，看看是否存在策略问题。
