[英]java.net.ConnectException: Failed to connect to localhost/127.0.0.1:xxxx while invoking Firefox browser in Headless mode
I am getting a "java.net.ConnectException: Failed to connect to localhost" error whenever I try to initialize the FirefoxDriver. 每当我尝试初始化FirefoxDriver时,我都会收到“ java.net.ConnectException:无法连接到本地主机”错误。 Any Help?
有帮助吗?
Code and Stack Trace Below: 下面的代码和堆栈跟踪:
Java Code Java代码
firefoxBinary = new FirefoxBinary();
firefoxBinary.addCommandLineOptions("--headless");
System.setProperty("webdriver.gecko.driver", (String) pluginConfig.get("geckodriver"));
firefoxOptions = new FirefoxOptions();
firefoxOptions.setBinary(firefoxBinary);
driver = new FirefoxDriver(firefoxOptions);
This line throws the error 这行抛出错误
driver = new FirefoxDriver(firefoxOptions);

Not sure about the contents of pluginConfig file. 不确定pluginConfig文件的内容。 In general to invoke Firefox Browser in Headless Mode programatically through Selenium 3.12.0 , GeckoDriver v 0.20.1 , Firefox Quantum v60.0.2 and Java you need to pass the
argument
--headless through an instance of FirefoxOptions and you can use the following solution: 通常,要通过Selenium 3.12.0 , GeckoDriver v 0.20.1 , Firefox Quantum v60.0.2和Java以编程方式在无头模式下调用Firefox浏览器 ,您需要将
argument
--headless通过FirefoxOptions实例传递 ,您可以使用以下解决方案:

import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.firefox.FirefoxOptions; public class A_Firefox_Headless { public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "/path/to/geckodriver"); FirefoxOptions options = new FirefoxOptions(); options.addArguments("--headless"); WebDriver driver = new FirefoxDriver(options); System.out.println("Mozilla Firefox Headless Browser Initialized"); driver.get("http://www.google.com"); System.out.println("Page Title is : "+driver.getTitle()); driver.quit(); } }

Resolved it.The problem was that, I was using a corrupted copy of geckodriver and it gave the following error above the stacktrace. 解决了问题是,我使用的是geckodriver损坏的副本,它在stacktrace上方给出了以下错误。
