Question

我想在以下网站上抓取一些信息：https://www.caixabank.es/particular/prestamos-personales/prestamos.html

我编码后进入了仿真页面，但是链接使我崩溃了。

我无法点击此链接。

我的目标网页是那个

我的代码：

from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--start-maximized')
chrome_options.add_argument('window-size=5000x2500')
webdriver = webdriver.Chrome('chromedriver',chrome_options=chrome_options)

now = DT.now()
periode = str(now.day) + '_' + str(now.month) + '_' + str(now.year)
#url = "https://www.caixabank.es/particular/prestamos-personales/prestamos.html"
url = "https://loc2.caixabank.es/GPeticiones?CANAL=I&DEMO=0&PN=LGN&PE=116&ENTORNO=1&sinCampanya=S&INICIAL_PN=PPP&INICIAL_PE=832&E_COD_LANDING=WGN00645&E_PNMENU=POS&E_PEMENU=6&TEXTO_OPE=prestamoestrellaautoes.txt&IDIOMA=02"
webdriver.get(url)
link = webdriver.find_element_by_partial_link_text('Demostración')
actions = ActionChains(webdriver).click(link)
actions.perform()
time.sleep(5)
webdriver.save_screenshot('sreenshot.png')
webdriver.implicitly_wait(30)
webdriver.switch_to.frame(webdriver.find_element_by_css_selector('#FramesetInferiorInterno > frame:nth-child(2)'))
webdriver.find_element_by_xpath("//a[contains(., 'Aceptar y continuar')]")
webdriver.save_screenshot('sreenshot1.png')

我得到的错误是：

/usr/local/lib/python3.6/dist-packages/ipykernel_launcher.py:8: DeprecationWarning: use options instead of chrome_options

我认为您可能只需要用括号括住xpath而不是括号：

webdriver.find_element_by_xpath("//a[contains(., 'Aceptar y continuar')]")

那一个可行吗？
