已导入相关模块，为何这段Selenium自动化表单填充代码无法运行？

先贴出你提供的原代码：

from selenium.webdriver.support import expected_conditions as EC
import time

# 1. Setup Service and Driver
service = Service('C:/Users/HP/Desktop/Drivers/chromedriver_win32/chromedriver.exe')
driver = webdriver.Chrome(service=service)

# 2. Define Data
datas = [
    ['Mary D Joiner', 'MaryDJoiner@gmail.com', '4079025063', '2474 McDonald Avenue, Maitland', 'NA'],
    ['Karen B Johnson', 'KarenBJohnson@gmail.com', '3153437575', '2143 Oak Street, GRAND ISLE', 'NA'],
]
try:
    for data in datas:
        driver.get('https://forms.gle/28PLHQyMXKAxsENx6')
        
        # 3. Wait for elements using Explicit Wait
        wait = WebDriverWait(driver, 10)
        textboxes = wait.until(EC.presence_of_all_elements_located((By.CLASS_NAME, "quantumWizTextinputPaperinputInput")))
        textareaboxes = driver.find_elements(By.CLASS_NAME, "quantumWizTextinputPapertextareaInput")
        
        # 4. Fill Inputs
        count = 0
        for box in textboxes:
            box.send_keys(data[count])
            count += 1
            
        for area in textareaboxes:
            area.send_keys(data[count])
            count += 1
            
        # 5. Submit
        submit = driver.find_element(By.XPATH, '//*[@id="mG61Hd"]/div[2]/div/div[3]/div[1]/div/div/span/span')
        submit.click()
        
        # Give a brief moment for submission to process
        time.sleep(2) 

以下是代码无法正常运行的常见问题及修复方案：

• 缺失核心导入模块：代码里用到了Service、webdriver、WebDriverWait、By，但仅导入了EC和time，必须补充导入：

  from selenium import webdriver
  from selenium.webdriver.chrome.service import Service
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  

• 元素定位方式不稳定：Google表单的类名（如quantumWizTextinputPaperinputInput）属于动态生成类名，随时可能变更，建议改用更稳定的定位逻辑：

  • 文本框：通过标签+类型属性定位
  • 文本域：通过标签直接定位
    示例：

  # 等待所有输入框加载完成（匹配文本、邮箱、电话类型）
  textboxes = wait.until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, 'input[type="text"], input[type="email"], input[type="tel"]')))
  # 定位文本域
  textareaboxes = wait.until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, 'textarea')))
  

• 提交按钮绝对XPATH易失效：原代码用的绝对XPATH依赖页面结构，一旦Google表单调整布局就会失效，换成相对定位：

  # 按按钮角色和标签定位提交按钮
  submit = wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'div[role="button"] span')))
  

• 索引越界风险：如果textboxes+textareaboxes的数量和data列表长度不匹配，会触发IndexError，建议添加长度校验：

  total_fields = len(textboxes) + len(textareaboxes)
  if total_fields != len(data):
      print(f"跳过当前数据：数据长度{len(data)}与字段数量{total_fields}不匹配")
      continue
  

• 缺少异常处理与资源清理：原代码只有try块，没有捕获异常和关闭浏览器的逻辑，容易导致进程残留，补充完整：

  except Exception as e:
      print(f"运行出错：{str(e)}")
  finally:
      # 无论成功失败都关闭浏览器
      driver.quit()
