Question

我正在运行以下代码：

    System.setProperty("webdriver.chrome.driver",     "C:/Softwares/selenium/chromedriver_win32/chromedriver.exe");

    WebDriver driver = new ChromeDriver(capability);
        driver.get("https://facebook.com/");         
        System.out.println("Page title is: " + driver.getTitle());

        driver.findElement(By.id("email")).sendKeys("Administrator");
        driver.findElement(By.id("pass")).sendKeys("12iso*help");
        System.out.println("Enter usrname as: "+driver.findElement(By.id("email")).getText());
        driver.findElement(By.id("u_0_q")).click();                     
        System.out.println("Page title is: " + driver.getTitle());   
    //driver.quit();

这可以按预期工作。但现在我尝试使用phantomjs使用无头镀铬浏览器代码：

WebDriver driver;
        File file = new File("C:/Softwares/phantomjs-2.1.1-windows/phantomjs-2.1.1-windows/bin/phantomjs.exe");             
        System.setProperty("phantomjs.binary.path", file.getAbsolutePath());

        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setJavascriptEnabled(true);

        caps.setCapability(
                                PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
                                "C:/Softwares/phantomjs-2.1.1-windows/phantomjs-2.1.1-windows/bin/phantomjs.exe"
                            );
        //caps.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, new String[] {"--web-security=no", "--ignore-ssl-errors=yes"});
        driver = new PhantomJSDriver(caps);


        driver.get("https://facebook.com/");         
        System.out.println("Page title is: " + driver.getTitle());

        driver.findElement(By.id("email")).sendKeys("Administrator");
        driver.findElement(By.id("pass")).sendKeys("12iso*help");
        System.out.println("Enter usrname as: "+driver.findElement(By.id("email")).getText());
        driver.findElement(By.id("u_0_q")).click();                     
        System.out.println("Page title is: " + driver.getTitle());

这显示了一个错误。

我确定，url在显示页面标题时已正确打开。但是可以请任何人帮助为什么phantomjs无法找到页面上的元素。谢谢！

Answer 1

这是工作代码：（需要注意的是，在Sysout中，标题将与登录失败相同，因此驱动程序获得相同的标题）

File src = new File("C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
System.setProperty("phantomjs.binary.path", src.getAbsolutePath());
WebDriver driver = new PhantomJSDriver();
driver.get("https://www.facebook.com/");
System.out.println(driver.getTitle());
Thread.sleep(2000);
driver.findElement(By.name("email")).sendKeys("Administrator");
driver.findElement(By.name("pass")).sendKeys("12iso*help");
driver.findElement(By.name("login")).click(); 
Thread.sleep(2000);
System.out.println("Page title is: " + driver.getTitle());

让我知道它是否对你有所帮助。

Answer 2

这对我有用：

System.setProperty("phantomjs.binary.path", seleniumBrowserDriverPath);
DesiredCapabilities caps = new DesiredCapabilities();
caps.setJavascriptEnabled(true);
caps.setCapability("locationContextEnabled", true);
caps.setCapability("applicationCacheEnabled", true);
caps.setCapability("browserConnectionEnabled", true);
caps.setCapability("localToRemoteUrlAccessEnabled", true);
caps.setCapability("locationContextEnabled", true);
caps.setCapability("takesScreenshot", true);
caps.setCapability(PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,
    seleniumBrowserDriverPath);
PhantomJSDriver driver = new  PhantomJSDriver(caps);

用Selenium 3在无头幻影2.1.1中找不到元素
