Question

이것은 시도한 코드입니다. 다른 stackoverflow 페이지에서 얻었지만 작동하지 않았습니다. 왜 어떤 아이디어?

chrome = webdriver.Chrome() 
chrome.get('http://stackoverflow.com/') 

# now that we have the preliminary stuff out of the way time to get that image :D 
element = chrome.find_element_by_class_name('-img') # find part of the page you want image of 
location = element.location 
size = element.size 
chrome.save_screenshot('screenshot.png') # saves screenshot of entire page 
chrome.quit() 

raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: unknown error: cannot get automation extension from unknown error: page could not be found: chrome-extension://aapnijgdinlhnhlmodcfapnahmbfebeb/_generated_background_page.html (Session info: chrome=57.0.2987.133) (Driver info: chromedriver=2.25.426923 (0390b88869384d6eb0d5d09729679f934aab9eed),platform=Windows NT 10.0.10586 x86_64)

Answer 1

당신은 당신의 chromedriver을 업데이트해야합니다 : 는

from selenium import webdriver 
from selenium.webdriver.chrome.options import Options 


chrome_options = Options() 
chrome_options.add_argument("--disable-extensions") 
chrome = webdriver.Chrome(chrome_options=chrome_options) 

chrome.get('http://stackoverflow.com/') 

# now that we have the preliminary stuff out of the way time to get that image :D 
element = chrome.find_element_by_class_name('-img') # find part of the page you want image of 
location = element.location 
size = element.size 
chrome.save_screenshot('screenshot.png') # saves screenshot of entire page 
chrome.quit()
