Selenium在调试期间正常,但运行单击失败

您的按钮似乎启动了一个AJAX请求。驱动程序不会等待它完成,因为没有页面重新加载。因此,应该添加显式等待。诸如此类:

expected_number_of_articles = 10 # enter your number
article_locator = (By.CSS_SELECTOR, 'div#article') # enter your locator
wait.until(lambda driver: len(driver.find_elements(*article_locator)) >= expected_number_of_articles)

在访问页面源之前,请等待一个小间隔以等待页面加载

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
import time
driver = webdriver.Firefox()
driver.get('https://baijia.baidu.com')
wait = WebDriverWait(driver,10)
wait.until(EC.element_to_be_clickable((By.ID, 'getMoreArticles'))).click()
time.sleep(4)
content = driver.page_source
page = open('test3.html','w')
page.write(content)
