如何爲PhantomJS設置超時時間？

Question

下面是我對設置它的代碼：

from selenium import webdriver 
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities 
dcap = dict(DesiredCapabilities.PHANTOMJS) 
dcap["phantomjs.page.settings.resourceTimeout"] = ("5000") 
driver = webdriver.PhantomJS(desired_capabilities=dcap) 

但是在我的超長腳本，它似乎並沒有超時的時候我的互聯網是緩慢的，一個頁面需要超過5秒加載。

關於PhantomJS超時的文檔很少，更少的文檔是針對Python的，所以我想這可能不是這樣的。

有沒有人在Python中用PhantomJS成功設置超時？

謝謝！

Answer 1

的定位，而不是phantomjs資源超時，您可以設置驅動器超時像例如Firefox的驅動程序如下：

browser = webdriver.Firefox() 
browser.set_page_load_timeout(30) 

你可以改變30到任何數字

感謝

Answer 2

您可以使用默認的Python sleep方法重試幾次。

import time 
time.sleep()
