python - 如何在数组中循环url并在驱动程序中打印css选择器元素，Python Selenium

问题描述

想要使用 selenium web 驱动程序查找每个产品的销售数量（给定数组中的 url）

这是我的代码

urls=["https://shopee.com.my/Pantene-Shampoo-750ml-i.52968176.7669592698/","https://shopee.com.my/PureMAE-Ylang-Ylang-and-Grapefruit-Shampoo-250ML-i.238433989.4820842024/","https://shopee.com.my/Some-By-Mi-Cica-Peptide-Anti-Hair-Loss-Shampoo-285ml-Tonic-150ml-Treatment-50ml-i.18874494.3274522052/","https://shopee.com.my/-JULYME-Anti-Hair-Loss-Perfume-Hair-Shampoo-500ml-i.219158269.6815232839/"]

for url in urls:
  driver.get(url)
  print(driver.find_element_by_css_selector('div.aca9MM').text)

预期结果是：

3.4k 13 5.3k 1.9k

但我在第 5 行出错，只能打印出第一个 3.4k

driver = webdriver.Chrome('/Users/YOURNAME/Desktop/chromedriver')

#for every url in the list of urls
try:
    for url in urls:
        driver.get(url)
        print(driver.find_element_by_css_selector('div.aca9MM').text)

except:
    print("error")    


3.4k

13

error

您提供的第三个 URL 上似乎没有 div.aca9MM 。
