关闭警报不起作用.每次使用python并使用chrome webdriver时，都会出现错误.传递登录名和密码可以正常工作.

Dismissing the alert doesn't work. I get an error every time, I'm using python and working with chrome webdriver. Passing login and password works fine.

我非常感谢您的帮助:)谢谢:D

I would really appreciate some help:) Thanks:D

from selenium import webdriver import time browser = webdriver.Chrome('My chromedriver path') a = 1 while a == 1: try: browser.get('www.facebook/') time.sleep(2) l = browser.find_element_by_id('email') l.send_keys('myphonenumber') l = browser.find_element_by_id('pass') l.send_keys('myspassword') l = browser.find_element_by_id('loginbutton') l.click() time.sleep(7) #code works to here and then breaks with error b = browser.switch_to.alert() b.dismiss() time.sleep(2) l = browser.find_element_by_xpath('//*[@id="js_9p"]/div/div/ul/li[1]/a') time.sleep(2) l.click() except: print('error occured, trying again')

这是我得到的错误:

raise exception_class(message, screen, stacktrace) seleniummon.exceptions.NoAlertPresentException: Message: no such alert (Session info: chrome=80.0.3987.149)

推荐答案

尝试使用 chrome_options ，它将取消通知.

Try using chrome_options, it will suppress the notification.

from selenium import webdriver from selenium.webdriver.chrome.options import Options import time options = webdriver.ChromeOptions() preferences = {"profile.default_content_setting_values.notifications" : 2} options.add_experimental_option("prefs", preferences) browser = webdriver.Chrome(chromedriver, chrome_options=options) browser.get('www.facebook/') time.sleep(2) l = browser.find_element_by_id('email') l.send_keys('username') l = browser.find_element_by_id('password') l.send_keys('password') l = browser.find_element_by_id('loginbutton') l.click() time.sleep(7)
