【问题描述】：

我有这个：

System.setProperty("webdriver.gecko.driver", "gecko/linux/geckodriver");

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.no_proxies_on", "localhost");
profile.setPreference("javascript.enabled", true);

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
capabilities.setCapability(FirefoxDriver.PROFILE, profile);

FirefoxOptions options = new FirefoxOptions();
options.setLogLevel(Level.FINEST);
options.addPreference("browser.link.open_newwindow", 3);
options.addPreference("browser.link.open_newwindow.restriction", 0);

现在我有两个不同的构造函数：

WebDriver driver = new FirefoxDriver(capabilities);

和

WebDriver driver = new FirefoxDriver(options);

如何将它们（功能和选项）都传递到driver？顺便说一句，IDE 告诉我 FirefoxDriver(capabilities) 已弃用。

【参考方案1】：

你快到了。您需要使用 MutableCapabilities 类中的方法 merge() 将 DesiredCapabilities 类型的对象合并到 FirefoxOptions 类型的对象中并启动 WebDriver和 WebClient 实例通过传递 FirefoxOptions 对象如下：

System.setProperty("webdriver.gecko.driver", "gecko/linux/geckodriver");

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.no_proxies_on", "localhost");
profile.setPreference("javascript.enabled", true);

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
capabilities.setCapability(FirefoxDriver.PROFILE, profile);

FirefoxOptions options = new FirefoxOptions();
options.merge(capabilities);
options.setLogLevel(Level.FINEST);
options.addPreference("browser.link.open_newwindow", 3);
options.addPreference("browser.link.open_newwindow.restriction", 0);

WebDriver driver = new FirefoxDriver(options);

【讨论】：

它叫我java.lang.IllegalArgumentException: Preference browser.link.open_newwindow may not be overridden: frozen value=2, requested value=3...我该怎么办？

@assembler 该错误与您作为 browser.link.open_newwindow.restriction / 0 传递的 Key / Value 对有关。但这个答案是为了满足您将功能和选项传递给 Firefoxdriver

的需要

【参考方案2】：

您可以将功能传递给firefoxoptions constructor，如下所示：

System.setProperty("webdriver.gecko.driver", "gecko/linux/geckodriver");

   FirefoxProfile profile = new FirefoxProfile();
   profile.setPreference("network.proxy.no_proxies_on", "localhost");
   profile.setPreference("javascript.enabled", true);

   DesiredCapabilities capabilities = DesiredCapabilities.firefox();
   capabilities.setCapability("marionette", true);

   FirefoxOptions options = new FirefoxOptions(capabilities);

set profile to firefox options
   options.setProfile(profile);
   options.setLogLevel(Level.FINEST);
   options.addPreference("browser.link.open_newwindow", 3);
   options.addPreference("browser.link.open_newwindow.restriction", 0);
pass firefox options as parameter to create driver
   WebDriver driver = new FirefoxDriver(options);
