org.openqa.selenium.TimeoutException：使用 AutoCloseable 在 Ubuntu 中运行无头 Firefox 浏览器时连接被拒绝错误

Question

错误：

org.openqa.selenium.TimeoutException: 连接被拒绝 构建信息：版本：'3.141.59'，修订：'e82be7d358'，时间：'2018-11-14T08:25:48' 系统信息：主机：'ubuntu'，ip：'127.0.0.1'，os.name：'Linux'，os.arch：'amd64'，os.version：'4.15.0-112-generic'，java.version ：'1.8.0_252' 驱动信息：driver.version：FirefoxDriver

代码：

System.setProperty("webdriver.gecko.driver", "/usr/bin/geckodriver");
FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setHeadless(true);

java.util.logging.Logger.getLogger("org.openqa.selenium").setLevel(Level.OFF);
System.out.println(1);

WebDriver driver = new FirefoxDriver(firefoxOptions);
// code does not reach this point. Look like its freezing at the initialisation of 'driver'.
try (AutoCloseable autoCloseable = () -> driver.close()) {
         ...

我已将 Java 版本更改为另一个建议的问题（从 11 到 8）。

编辑：该帖子 (Java Selenium Webdriver Connection Refused) 无效。

编辑 #2：我通过 Tomcat 9 运行它。

Answer 1

我没有看到您的代码块有任何此类问题。我采用了您的代码并使用以下配置执行：

• 操作系统：windows-10
• java-8: JDK 8u251
• Selenium: 最新稳定版3.141.59
• GeckoDriver: GeckoDriver v0.26.0
• Firefox：最新稳定版本 79.0

执行细节

这里是使用autocloseable的执行细节：

• 代码块：

  import java.util.logging.Level;
  
  import org.openqa.selenium.firefox.FirefoxDriver;
  //import org.openqa.selenium.firefox.FirefoxDriverLogLevel;
  import org.openqa.selenium.firefox.FirefoxOptions;
  
  public class AutoCloseableSelenium {
  
      public static void main(String[] args) throws Exception {
  
          System.setProperty("webdriver.gecko.driver","C:\\WebDrivers\\geckodriver.exe");
          FirefoxOptions options = new FirefoxOptions();
          options.setHeadless(true);
          //options.setLogLevel(FirefoxDriverLogLevel.TRACE);
          java.util.logging.Logger.getLogger("org.openqa.selenium").setLevel(Level.OFF);
          System.out.println(1);
          FirefoxDriver driver = new FirefoxDriver(options);
          try (AutoCloseable autoCloseable = () -> driver.quit()) { }
          System.out.println("Exiting program");
    }
  

  }
