Python Selenium实现模拟浏览器点击页面按钮实战教程

步骤：

1. 将chromedriver.exe（https://chromedriver.storage.googleapis.com/index.html?path=2.35/）下载放到Python文件夹里面

2. 运行命令安装Selenium

pip install Selenium==3.3.1

3. 创建代码

根据要求书写：打开页面-点击banner广告-返回上一页-刷新页面

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

# 初始化Chrome浏览器
driver = webdriver.Chrome()

# 打开指定的URL
driver.get("website_address")

while True:
    # 刷新页面
    driver.refresh()
    print("Refreshed page")

    # 等待页面加载完成
    wait = WebDriverWait(driver, 10)
    element_ad = wait.until(EC.presence_of_element_located((By.XPATH, '//* 
    [@id="advertViewDom"]/uni-view/uni-swiper/div/div[1]/div/uni-swiper-item[1]/uni- 
    view/uni-image[1]')))

    # 确保广告是可见的
    if element_ad.is_displayed():
        # 点击广告
        element_ad.click()
        print("Clicked on ad")
    else:
        print("Ad is not visible")

    # 尝试返回上一页
    try:
        driver.back()
        print("Returned to previous page")
    except Exception as e:
        print(f"Failed to go back: {e}")

    # 如果不在首页，跳出循环
    if driver.current_url != "website_address":
        break

p.s. 如何找到XPath？

打开chrome，F12，找到需要点击的元素，右键copy-copy
