java - Selenium 中的 pageLoadTimeout 不起作用

Question

我在 Java 中使用 selenium 使用以下代码。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<WebElement> facilitySectionList = driver.findElements(By.className("facilitiesChecklistSection"));

解决你的 pageLoadTimeout 问题是提高你的 Selenium 版本到 v3.5.0。这是有效的代码块和结果 org.openqa.selenium.TimeoutException: Timeout loading page after 2000ms 用最少的行编写您自己的代码:

• 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.
