硒在调整chromedriver窗口的大小时找不到元素

Question

当我使用selenium时，它运行良好，直到我最小化/调整chromedriver.exe窗口的大小。当我这样做时，会引发诸如"element not found"之类的异常。我该怎么做才能避免这种情况？

Answer 1

首先，你可以尝试无头：

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.add_argument('--headless')
options.add_argument('--disable-gpu')  # Last I checked this was necessary.
driver = webdriver.Chrome(CHROMEDRIVER_PATH, chrome_options=options)

第二，您可以尝试等待：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delays_loading")
try:
element = WebDriverWait(driver, 10).until(
EC.presence_of_element_located((By.ID, "myDynamicElement"))
)
finally:
driver.quit()
