使用Selenium抓取Bing Chat遇元素不可交互问题求助

问题 #

尝试用Selenium抓取Bing Chat回复时，执行inp.click()步骤出现element not interactable错误。确认目标textarea带有b_searchbox类，改用xpath或id定位仍报错。实现代码如下：

import undetected_chromedriver as uc
from time import sleep
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
from selenium import webdriver
from selenium_stealth import stealth


options = webdriver.ChromeOptions()
options.add_extension(r"D:\chromext\extension_1_0_5_0.crx")
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)

driver = webdriver.Chrome("D:\chrome driver\chromedriver.exe", options=options)
driver.maximize_window()

driver.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {
     "source": """\n          const newProto = navigator.__proto__\n          delete newProto.webdriver\n          navigator.__proto__ = newProto\n          """
    })
stealth(driver,
        languages=["en-US", "en"],
        vendor="Google Inc.",
        platform="Win32",
        webgl_vendor="Intel Inc.",
        renderer="Intel Iris OpenGL Engine",
        fix_hairline=True,
        )


driver.get('https://login.live.com/login.srf?wa=wsignin1.0&rpsnv=13&id=264960&wreply=https%3a%2f%2fwww.bing.com%2fsecure%2fPassport.aspx%3fedge_suppress_profile_switch%3d1%26requrl%3dhttps%253a%252f%252fwww.bing.com%252fsearch%253ftoWww%253d1%2526redig%253dCF6FAA3B24AB4DB69ADB641F4381D432%2526q%253dBing%252bAI%2526showconv%253d1%2526wlexpsignin%253d1%26sig%3d300479B8A0DF658D00BB6B57A1CD6457&wp=MBI_SSL&lc=1033&CSRFToken=1df1d208-abf2-4cf1-98c8-b17e091b4dd1&aadredir=1')
mail = driver.find_element_by_xpath('//*[@id="i0116"]')
mail.send_keys('pasw')
mail.send_keys(Keys.ENTER)
sleep(2)
pasw = driver.find_element_by_xpath('//*[@id="i0118"]')
pasw.send_keys('login')
pasw.send_keys(Keys.ENTER)
driver.find_element_by_xpath('//*[@id="iLandingViewAction"]').click()
driver.find_element_by_xpath('//*[@id="idSIButton9"]').click()
sleep(3)
driver.get('https://www.bing.com/search?toWww=1&redig=AD6EA0F2A6224B5989B5A577FCFB4100&q=Bing+AI&showconv=1')
sleep(5)
driver.implicitly_wait(10)   
inp = driver.find_element_by_class_name('b_searchbox')
inp.click()
inp.send_keys('hi, are you better than chatgpt?')
inp.send_keys(Keys.ENTER)
# ActionChains(driver).move_to_element(button).click(button).perform()
sleep(1000)

解决方案 #

1. 使用显式等待确保元素可交互 #

element not interactable大多因元素未完全加载或未处于可交互状态，用显式等待替代固定sleep和隐式等待，精准等待元素可点击：

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

# 替换登录后的页面跳转及元素定位代码
driver.get('https://www.bing.com/search?toWww=1&redig=AD6EA0F2A6224B5989B5A577FCFB4100&q=Bing+AI&showconv=1')
# 等待输入框可交互，超时时间设为20秒
inp = WebDriverWait(driver, 20).until(
    EC.element_to_be_clickable((By.CLASS_NAME, 'b_searchbox'))
)
inp.click()
inp.send_keys('hi, are you better than chatgpt?')
inp.send_keys(Keys.ENTER)

2. 处理页面遮挡元素 #

Bing Chat页面可能存在弹窗、加载遮罩等遮挡输入框，可通过以下方式解决：

• 检查页面是否有隐私政策或条款弹窗，优先点击关闭
• 若元素被遮挡但已存在，用JS强制触发点击：

inp = WebDriverWait(driver, 20).until(
    EC.presence_of_element_located((By.CLASS_NAME, 'b_searchbox'))
)
# 用JavaScript强制点击元素
driver.execute_script("arguments[0].click();", inp)

3. 改用Undetected Chromedriver #

代码中导入了undetected_chromedriver但未使用，普通ChromeDriver易被Bing的反爬机制检测到，替换初始化逻辑：

# 替换原driver初始化代码
driver = uc.Chrome(options=options)

4. 优化页面跳转路径 #

登录完成后直接访问Bing Chat的专属对话页面，减少中间页面的加载问题：

# 登录后直接跳转至Bing Chat
driver.get('https://www.bing.com/chat')
