java - 线程 "main"中的异常 org.openqa.selenium.WebDriverException : Timed out waiting 45 seconds for Firefox to start after geckodriver upgradation

Question

我已经用 java 编写了以下代码来打开 firefox 并重定向到 gmail.com 链接，但似乎它在重定向之前超时了。我已经检查了 stackoverflow 中的解决方案，发现其他人也面临同样的问题。他/她升级了回溯的 geckodriver，之后它成功重定向到他/她的链接。看到之后，我检查了 geckodriver、firefox 和 selenium 的版本，似乎一切都已更新。 geckodriver的版本是v0.20.1，firefox版本是60.0.2，selenium是3.12.0。我写的代码是:

System.setProperty("webdriver.gecko.driver", "C:\\Users\\MI SERVICE\\Downloads\\geckodriver.exe");
FirefoxOptions capa = new FirefoxOptions();
capa.setCapability("marionette", false);
WebDriver driver = new FirefoxDriver(capa);
driver.navigate().to("https://www.gmail.com");
driver.quit();

引发的异常:

Answer 1

当您使用 Selenium v​​3.12.0 时，GeckoDriver 是 v0.20.1 和 Firefox v60.0.2 您必须强制使用 < strong>ma​​rionette 这是默认配置。由于您已将 marionette 强行设置为 false，因此您会看到以下错误:

org.openqa.selenium.WebDriverException: Timed out waiting 45 seconds for Firefox to start.

解决方案:

有两种方法可以解决您的问题，如下所示:

• 要么使用默认配置(marionette 设置为 true)，如下所示:

  System.setProperty("webdriver.gecko.driver", "C:\Users\MI SERVICE\Downloads\geckodriver.exe");
  WebDriver driver = new FirefoxDriver();
  driver.navigate().to("https://www.gmail.com");
  driver.quit();
  

• 或者您可以显式地将 marionette 设置为 true，如下所示:

  System.setProperty("webdriver.gecko.driver", "C:\Users\MI SERVICE\Downloads\geckodriver.exe");
  FirefoxOptions capa = new FirefoxOptions();
  capa.setCapability("marionette", true);
  WebDriver driver = new FirefoxDriver(capa);
  driver.navigate().to("https://www.gmail.com");
  driver.quit();
