How to make selenium to reload the desired url if it takes too long loading

问题

I want selenium to force the browser to reload the page which it is loading if the loading process takes too long.

From StackOverflow I have that this code

new WebDriverWait(driver, 30).until((ExpectedCondition<Boolean>) wd -> ((JavascriptExecutor) wd)
                .executeScript("return document.readyState").equals("complete"));

will wait until the page is fully loaded, but I want it to be reloaded if it takes more than 30 seconds.

How can I achieve that?

回答1:

To reload the webpage incase the loading process is taking too long you can configure pageLoadTimeout. pageLoadTimeout sets the amount of time to wait for a page load to complete before throwing an error. If the timeout is negative, page loads can be indefinite.

An example (using Selenium v3.141.59 and GeckoDriver v0.24.0):

Code Block:

public class 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);
        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");
          // do your other work here
        }catch(WebDriverException e){
          System.out.println("WebDriverException occured");
          }
        driver.quit();
    }
}

Console Output:

回答2:

WebDriverWait with through timeout exception. Put your code inside try/catch and reload the page on timeout exception:

try {
    new WebDriverWait(driver, 30).until((ExpectedCondition<Boolean>) wd -> ((JavascriptExecutor) wd)
            .executeScript("return document.readyState").equals("complete"));
} catch (TimeoutException e) {
    // log a timeout
    // System.out.println("Page load timeout, refresh.");
    driver.navigate().refresh();
}

回答3:

Try _driver.Navigate().Refresh();
