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

Question

Error:

org.openqa.selenium.TimeoutException: connection refused Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:25:48' System info: host: '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' Driver info: driver.version: FirefoxDriver

Code:

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()) {
         ...

I have changed Java Version as another question recommended (from 11 to 8).

EDIT: That post ( Java Selenium Webdriver Connection Refused ) did not work.

EDIT #2: I am running it through Tomcat 9.

Answer 1

I don't see any such issue with your code block. I took your code and executed with the following configuration:

• OS : windows-10
• java-8 : JDK 8u251
• Selenium : Latest stable version 3.141.59
• GeckoDriver : GeckoDriver v0.26.0
• Firefox : Latest stable version 79.0

Execution details

Here are the execution details using autocloseable :

• Code Block:

   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"); }

  }
