Question

我正在自动化网站以获取一些数据。我曾经在某个时候使用过显式/隐式等待，效果很好。但是当URL更改为另一个页面时..我猜它在加载其DOM时遇到问题，我找不到任何元素。有什么办法可以找到元素

我尝试使用睡眠，将元素定位符更改为ID，CLASS，CSS SELECTOR，XPATH，TITLE等。尝试将最大超时时间更改为30分钟

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
import time

driver = webdriver.Chrome(r".\chromedriver")
driver.implicitly_wait(180)
driver.maximize_window()
driver.get("url")
elem_username = driver.find_element(By.CSS_SELECTOR, 'some_selector')
elem_username.clear()
elem_username.send_keys("user-name")
elem_pass = driver.find_element(By.CSS_SELECTOR, 'some_selector')
elem_pass.clear()
elem_pass.send_keys("pass-word")
elem_login = driver.find_element(By.CLASS_NAME, 'some-class').click()

#element = WebDriverWait(driver, 180).until(EC.presence_of_element_located((By.ID, "some-id")))
elem_click = driver.find_element(By.ID, "some-id").click()

t1 = time.asctime()
print(t1)
#unable to find below element after 30 min too
element = WebDriverWait(driver, 1800).until(EC.presence_of_element_located((By.CSS_SELECTOR, 'some-selector')))
t2 = time.asctime()
print(t2)
elem_search = driver.find_element(By.CSS_SELECTOR, 'some-selector').click()
elem_transact = driver.find_element(By.CSS_SELECTOR, 'some-selector').click()

错误消息是超时异常：

回溯（最近通话最近）：文件“ file.py”，第24行，在元素= WebDriverWait（驱动程序，1800）。直到（EC.presence_of_element_located（（由CSS_SELECTOR， '某些选择器'））文件“ C：\ Users \ tusmitta \ AppData \ Local \ Programs \ Python \ Python37 \ lib \ site-packages \ selenium \ webdriver \ support \ wait.py”， 80行，直到引发TimeoutException（消息，屏幕，堆栈跟踪） selenium.common.exceptions.TimeoutException：消息：

找不到元素，尝试在硒中显式等待python
