我有一个代码,用于返回网站列表的标题。有时,网站加载的时间很荒谬,因此,发生这种情况时,会提示超时错误。我希望这样做,以便在发生此类错误时,程序继续运行而不是完全停止。
代码是:
from pyvirtualdisplay import Display
from time import sleep
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
display = Display(visible=0, size(800,600))
display.start()
driver = webdriver.Firefox(executable_path='/usr/local/lib/geckodriver/geckodriver')
driver.set_page_load_timeout(60)
driver.get('https://google.com')
print(driver.title)
以下代码是导致60秒未加载页面时发生超时的原因:
driver.set_page_load_timeout(60)
60秒过后,程序将停止并提示超时错误。我希望它继续下一个URL。

即使在发生 page_load_timeout 错误的情况下,也要遍历URL的列表,您可以使用以下解决方案:
代码块:
try {
// application init
$app->init();
} catch (Doctrine\Common\Persistence\Mapping\MappingException $e) {
error_log("MappingException: " . $e->getTraceAsString());
throw $e;
}
控制台输出:
ini_set('log_errors_max_len', 0); // 0 - infinity length allow
注意:
from selenium import webdriver
from selenium.common.exceptions import TimeoutException
urls = ["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", "https://www.google.com/"]
driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe')
driver.set_page_load_timeout(2)
for url in urls:
try :
driver.get(url)
print("URL successfully Accessed ... Proceeding with other tasks !!!")
# perform other operations within the url
except TimeoutException as e:
print("Page load Timeout Occured ... moving to next item !!!")
driver.quit()
仅用于演示页面加载超时。您可以在How to set the timeout of 'driver.get' for python selenium 3.8.0?

您可以使用try来处理和传递任何错误。
from pyvirtualdisplay import Display
from time import sleep
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
from selenium import webdriver
from selenium.webdriver.firefox.options import Options
display = Display(visible=0, size(800,600))
display.start()
driver = webdriver.Firefox(executable_path='/usr/local/lib/geckodriver/geckodriver')
try:
driver.set_page_load_timeout(60)
except Exception as e:
print(e)
driver.get('https://google.com')
print(driver.title)
