你可以做的是创建一个配置文件，并保存在它的认证数据。

What you can do is to create a profile and save the authentication data in it. If your profile is called "webdriver" you can select it from your code in the initialization:

ProfilesIni allProfiles = new ProfilesIni(); 
FirefoxProfile profile = allProfiles.getProfile("WebDriver"); 
profile.setPreferences("foo.bar",23);
WebDriver driver = new FirefoxDriver(profile);
