我在 Java 中使用 selenium 使用下面的代码。我添加了 4 秒的 pageLoadTimeout，但是，驱动程序继续等待直到加载完整的页面。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"));

pageLoadTimeout您的问题的解决方案是将您的Selenium版本升级到v3.5.0。这是有效的代码块以及org.openqa.selenium.TimeoutException: Timeout loading page after 2000ms 您自己的代码在最少行中的结果：

  • 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");
    }
}

捕获 WebDriverException

          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");

              System.out.println("WebDriverException occured");
          }

如果你指定了时间，而 selenium 不能在指定时间加载站点，它会抛出TimedoutException. 你应该在你的代码中处理它。

    driver.manage().timeouts().pageLoadTimeout(4, TimeUnit.SECONDS);
    long startTime = System.currentTimeMillis();
    try{
        driver.get("https://yahoo.com");
    }catch (TimeoutException te){
        long estimatedTime = System.currentTimeMillis() - startTime;
        System.out.println("it took "+estimatedTime+" Time");
    }

如果它没有抛出TimeoutException，要么网站在指定时间内完成加载，要么 Selenium API 有问题。
