拒绝Java Selenium Webdriver连接

标签: java selenium selenium-webdriver geckodriver connection-refused

我在selenium webdriver上遇到了太常见的连接拒绝错误。几周前,相同的代码正在执行。

我一直在通过现有帖子阅读,并尝试更新geckodriver和FireFox无济于事。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。如何查找特定于此计算机的原因?错误如下。

即使是以下基本代码,我仍然可以运行。

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();
        }
 }

镀铬示例。

@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项政策,该政策阻止了对geckodriver.exe执行的访问。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中获得有意义的错误(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,尽管这可能是我的具体情况。如果Geckodriver出现此错误,我建议您尝试从cmd执行它以查看是否存在策略问题。

以下是您的问题的解决方案:

我在代码中没有看到任何错误,但错误堆栈跟踪HttpHostConnectException说明了这一切。

执行以下步骤:

  1. 我认为没有必要使用throws InterruptedException,您可以考虑将其删除。
  2. 根据最佳做法,尝试将geckodriver放在方便的位置:例如C:\\your_directory
  3. 避免将目录名称与Temp一起使用。

  4. 虽然您已经获得了DesiredCapabilities Class的帮助,但在启动驱动程序实例时尚未传递它。你必须这样做:

    WebDriver driver = new FirefoxDriver(capabilities);
    
  5. 清除您的Mozilla Firefox浏览器缓存。

  6. 从Windows任务管理器中,手动终止所有正在运行的geckodriver.exe
  7. 实例
  8. 您可能需要运行CCleaner以防止所有不需要的东西。
  9. 重启你的机器。
  10. 执行您的测试。它应该运作良好。
  11. 在测试步骤结束时,请致电driver.quit()以防止geckodriver实例悬空。

  12. 以下是您自己的工作代码块,添加了System.setProperty行:

    System.setProperty("webdriver.gecko.driver", "C:\\your_directory\\geckodriver.exe");
    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();
    
  13. 如果这有助于您,请告诉我。

我在这里遇到了同样的错误。系统重新启动后,代码可以正常工作。 我的问题是我的代码最后使一些进程处于打开状态,并且它们正在使用大量RAM。 尝试运行:

pkill geckodriver
pkill firefox
pkill selenium

然后再次运行您的代码。
