Selenium中的pageLoadTimeout无效

我在Java中使用selenium使用下面的代码。 我正在添加4秒的pageLoadTimeout，但是，驱动程序继续等待，直到加载完整的页面。 有帮助吗？

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 facilitySectionList = driver.findElements(By.className("facilitiesChecklistSection")); 

Answer 1

pageLoadTimeout问题的解决方案是将Selenium版本提升到v3.5.0 。 这是有效的代码块和结果org.openqa.selenium.TimeoutException: Timeout loading page after 2000ms在最小行中你自己的代码org.openqa.selenium.TimeoutException: Timeout loading page after 2000ms ：

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：

Answer 2

WebDriver.Timeouts – > pageLoadTimeout（long time，java.util.concurrent.TimeUnit unit）设置在抛出错误之前等待页面加载完成的时间。

pageLoadTimeout

 WebDriver.Timeouts pageLoadTimeout(long time,java.util.concurrent.TimeUnit unit) 

设置在抛出错误之前等待页面加载完成的时间。 如果超时为负，则页面加载可能是无限期的。 参数：time – 超时值。 unit – 时间单位。 返回：Timeouts接口。

Answer 3

如果指定时间，并且selenium无法加载站点指定的时间，则会抛出TimedoutException 。 您应该在代码中处理它。

  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出错。
