org.openqa.selenium.TimeoutException：在使用 AutoCloseable 在 Ubuntu 中運行無頭 firefox 瀏覽器時連接被拒絕錯誤

Question

錯誤：

org.openqa.selenium.TimeoutException：連接被拒絕構建信息：版本：'3.141.59'，修訂版：'e82be7d358'，時間：'2018-11-14T08:25:48' 系統信息：主機：'ubuntu'，Z94535B52768FCAD39D28 : '127.0.0.1', os.name: 'Linux', os.arch: 'amd64', os.version: '4.15.0-112-generic', java.version: '1.8.0_252' 驅動程序信息：驅動程序.version: FirefoxDriver

代碼：

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()) {
         ...

我已將 Java 版本更改為另一個建議的問題（從 11 到 8）。

編輯：那個帖子（ Java Selenium Webdriver Connection Refused ）沒有工作。

編輯#2：我通過 Tomcat 9 運行它。

Answer 1

我沒有看到您的代碼塊有任何此類問題。 我采用了您的代碼並使用以下配置執行：

• 操作系統： windows-10
• java-8 ： JDK 8u251
• Selenium ：最新穩定版3.141.59
• GeckoDriver : GeckoDriver v0.26.0
• Firefox : 最新穩定版79.0

執行細節

以下是使用autocloseable的執行細節：

• 代碼塊：

   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"); }

  }
