我正在设置我的init方法。
def __init__(self, ip_address):
""" Initialize a new Printer_Webpage object."""
self.ip_address = ip_address
chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--disable-gpu")
self.browser = webdriver.Chrome(chrome_options=chrome_options)
# Ignore lack of cert for each printer web page.
# Otherwise, can't open page.
self.browser.accept_untrusted_certs = True
像这样访问打印机。
def login(self):
"""Navigates through the login page for the printer."""
# Open login page
self.browser.get(f'https://{self.ip_address}/wcd/top.xml')
# STEPS TO LOGIN:
# 1) Select 'Administrator' radio button and click.
self.browser.find_element_by_id('Admin').click()
# 2) Select Login button and click.
self.browser.find_element_by_xpath("//input[@type='submit' \
and @value='Login']").click()
# 3) Select admin (user mode)
self.browser.find_element_by_id('R_ADM2').click()
# 4) Select password field and input PASSWORD, then submit.
password_field = self.browser.find_element_by_id('Admin_Pass')
password_field.send_keys(PASSWORD)
password_field.send_keys(Keys.RETURN)
整个脚本在头部镀铬中运行良好,但是当无头运行时我得到了这个错误:
selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"id","selector":"Admin"}
最初我认为也许元素还没有加载(跑步时需要几秒钟),但即使等待30秒也无济于事。
感谢任何帮助!
