java - 如何使用 PhantomJS 实现 Selenium WebDriver 以及我们可以将 Sikuli 与 PhantomJS 一起使用吗？

Question

我正在尝试使用以下代码在 PhantomJS 的 headless 浏览器中运行我的脚本。

public void setUp() throws Exception{
       Capabilities caps = new DesiredCapabilities();
       ((DesiredCapabilities) caps).setJavascriptEnabled(true);                
       ((DesiredCapabilities) caps).setCapability("takesScreenshot", true);  
       ((DesiredCapabilities) caps).setCapability(
               PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
               "/Users/kamal.kumar/Desktop/phantomjs-2.1.1-macosx/bin/phantomjs.exe"
           );
      // System.setProperty("webdriver.gecko.driver", "drivers/geckodriver");
       isr=new Scanner(System.in);
       ReadExcelFile ob=new ReadExcelFile();
       ArrayList<String> data=ob.extractData();

      // System.setProperty("webdriver.chrome.driver", "drivers/chromedriver");
       //driver=new ChromeDriver();
        driver=new PhantomJSDriver(caps);
       /*
       for(String i:data)
           System.out.println(i);
       */
       userName=data.get(0);
       password=data.get(1);
       approverName=data.get(2);
       activityCode=data.get(3);

       baseUrl="http://"+userName+":"+password+"@sparshv2/";

       driver.get(baseUrl);
       driver.manage().window().maximize();
       driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
   }

当我尝试运行它时出现错误:

或者我正在使用 Sikuli，它与 selenium 配合得很好。但现在因为我想从 selenium 转向 PhantomJS，所以我们可以将 Sikuli 与 PhantomJS 一起使用吗？

Answer 1

您可以尝试使用切换窗口的概念，首先保存父窗口的存在，然后跟踪子窗口的存在。然后切换到子窗口并在子窗口上执行所有操作，然后切换回父窗口。

Code:

   String parentWindowHandler = driver.getWindowHandle(); // Store your parent window
            String subWindowHandler = null;

            Set<String> handles = driver.getWindowHandles(); // get all window handles
            Iterator<String> iterator = handles.iterator();
            while (iterator.hasNext()){
                subWindowHandler = iterator.next();
            }
            driver.switchTo().window(subWindowHandler); 

*****perform operations on child window******************

driver.switchTo().window(parentWindowHandler);

希望这能解决您的问题
