Selenium中的pageLoadTimeout无法正常工作

Question

我在Java中使用以下使用selenium的代码。我要添加4秒的pageLoadTimeout，但是，驱动程序将继续等待，直到整个页面加载完毕。有什么帮助吗？

    System.setProperty("webdriver.gecko.driver", System.getProperty("user.home") + "\\Desktop\\geckodriver.exe");

            FirefoxBinary b = new FirefoxBinary(new File(System.getProperty("user.home") + "\\desktop\\Mozilla Firefox\\firefox.exe"));
            FirefoxOptions options = new FirefoxOptions().setBinary(b);
            driver = new FirefoxDriver(options);
            //driver.manage().timeouts().implicitlyWait(1, TimeUnit.SECONDS);
            driver.manage().timeouts().pageLoadTimeout(4, TimeUnit.SECONDS);


            driver.get("https://www.booking.com/hotel/in/the-taj-mahal-palace-tower.html?label=gen173nr-1FCAEoggJCAlhYSDNiBW5vcmVmaGyIAQGYATG4AQbIAQzYAQHoAQH4AQKSAgF5qAID;sid=338ad58d8e83c71e6aa78c67a2996616;dest_id=-2092174;dest_type=city;dist=0;group_adults=2;hip_dst=1;hpos=1;room1=A%2CA;sb_price_type=total;srfid=ccd41231d2f37b82d695970f081412152a59586aX1;srpvid=c71751e539ea01ce;type=total;ucfs=1&#hotelTmpl");
    List<WebElement> facilitySectionList = driver.findElements(By.className("facilitiesChecklistSection"));

解决该 pageLoadTimeout 问题的方法是将您的 Selenium 版本升级到 v3.5.0
。这是有效的代码块，并且使用 org.openqa.selenium.TimeoutException: Timeout loading page after 2000ms 最少的代码即可生成您自己的代码：

• 代码块：

        public class Q45591282_pageloadtimeout 
    {
        public static void main(String[] args) 
        {
              System.setProperty("webdriver.gecko.driver", "C:\\Utility\\BrowserDrivers\\geckodriver.exe");
              WebDriver driver=new FirefoxDriver();
              driver.manage().timeouts().pageLoadTimeout(2, TimeUnit.SECONDS);
              driver.get("https://www.booking.com/hotel/in/the-taj-mahal-palace-tower.html?label=gen173nr-1FCAEoggJCAlhYSDNiBW5vcmVmaGyIAQGYATG4AQbIAQzYAQHoAQH4AQKSAgF5qAID;sid=338ad58d8e83c71e6aa78c67a2996616;dest_id=-2092174;dest_type=city;dist=0;group_adults=2;hip_dst=1;hpos=1;room1=A%2CA;sb_price_type=total;srfid=ccd41231d2f37b82d695970f081412152a59586aX1;srpvid=c71751e539ea01ce;type=total;ucfs=1&#hotelTmpl");
        }
    }

• 控制台输出：

捕获WebDriverException

• 代码块：

        public class pageLoadTimeout 
    {
        public static void main(String[] args) 
        {
              System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
              WebDriver driver = new ChromeDriver();
              driver.manage().timeouts().pageLoadTimeout(2, TimeUnit.SECONDS);
              try{
                  driver.get("https://www.booking.com/hotel/in/the-taj-mahal-palace-tower.html?label=gen173nr-1FCAEoggJCAlhYSDNiBW5vcmVmaGyIAQGYATG4AQbIAQzYAQHoAQH4AQKSAgF5qAID;sid=338ad58d8e83c71e6aa78c67a2996616;dest_id=-2092174;dest_type=city;dist=0;group_adults=2;hip_dst=1;hpos=1;room1=A%2CA;sb_price_type=total;srfid=ccd41231d2f37b82d695970f081412152a59586aX1;srpvid=c71751e539ea01ce;type=total;ucfs=1&#hotelTmpl");
              }catch(WebDriverException e){
                  System.out.println("WebDriverException occured");
              }
              driver.quit();
        }
    }

• 控制台输出：

        Only local connections are allowed.
    Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.
