我在我的 selenium webdriver 上遇到了非常常见的连接被拒绝错误。几周前正在执行相同的代码。
我一直在循环阅读现有帖子，并尝试更新 geckodriver 和 FireFox，但无济于事。我可以在另一台运行相同版本的驱动程序、浏览器和库等的计算机上运行相同的代码。我如何才能找到特定于这台机器的原因？错误在下面。

我什至可以运行以下基本代码。
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();
}
}
铬的例子。
@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项政策，该政策阻止访问 geckodriver.exe 的执行。这是通过尝试从 cmd 运行来识别的。不知道为什么我没有在 IDE 中为 gecko 得到有意义的错误（被组策略阻止），我确实为 chrome 和 IE 得到了这个错误。为了使用驱动程序，它需要保存在程序文件中，尽管这可能特定于我的情况。如果您收到 Geckodriver 的此错误，我建议您尝试从 cmd 执行它以查看是否存在策略问题。
