java - PhantomJS 找不到这个元素 "driver.findElement(By.name("q")) selenium web driver Java

Question

我已经使用 selenium web driver java 编写了代码来搜索学校并从搜索中获取第一个 url。我的代码在没有 PhantomJS 的情况下运行良好。但是由于我想使用无头浏览器，请尝试以下代码进行更改。

WebElement element = driver.findElement(By.name("q"));PhantomJS 在下面的代码中找不到这个元素“ driver.findElement(By.name("q"));”，我也尝试了 id，但没有成功。

Capabilities caps = new DesiredCapabilities();

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

((DesiredCapabilities)caps).setCapability("takesScreenshot", true);

((DesiredCapabilities) caps).setCapability( PhantomJSDriverService.PHANTOMJS_EXECUTABLE_PATH_PROPERTY,"C:/Softwares/phantomjs-2.5.0-beta-windows/phantomjs-2.5.0.beta-windows/bin/phantomjs.exe");

// Initialize browser

WebDriver driver = new PhantomJSDriver(caps);

// And now use this to visit Google
driver.get("https://www.google.com");

// Maximize browser
driver.manage().window().maximize();

// find the text input element by its name
WebElement element = driver.findElement(By.name("q"));

String searchSchool = "Bay High School"

// enter something to search for
element.sendKeys(searchSchool);

System.out.println("school name is "+ searchSchool);

// now submit the form
element.submit();

Thread.sleep(500);

WebElement click = driver.findElement(By.name("btnG"));

click.click();

Thread.sleep(2000);

List<WebElement> listings = driver.findElements(By.tagName("div").xpath("//cite[@class='_Rm']"));

listings.size();
